The process involves transferring drawing files from a source Tekla Structures model to a destination model. This action facilitates the reuse of detailing work, promotes consistency across projects, and reduces duplication of effort. For instance, standard connection details, floor plans, or elevation views developed in one model can be readily implemented in another, ensuring uniform representation and adherence to established standards.
The ability to migrate drawing sets offers significant advantages in project management and workflow efficiency. It reduces the time required for detailing similar structures, enables standardization of construction documents, and minimizes the potential for errors arising from manual redrawing. Historically, this capability has evolved from simple file copying to more sophisticated methods incorporating revision control and attribute mapping, reflecting the increasing complexity and integration of BIM workflows.
Several methods exist for accomplishing this transfer, each with its own advantages and limitations. Understanding these methods and their implications for drawing properties, revision management, and model integrity is crucial for successful implementation. The following sections will explore the various techniques available, focusing on practical considerations and best practices.
1. Drawing File Format
The drawing file format directly impacts the effectiveness and feasibility of migrating drawings between Tekla Structures models. The native Tekla Structures drawing format (.db1) is generally the most reliable for preserving drawing integrity, object associations, and parametric relationships when transferring information. Attempting to transfer drawings using incompatible formats, such as .dwg or .dxf, can result in loss of data, altered visual representation, and broken links to the 3D model. This incompatibility necessitates manual rework to restore drawing fidelity and functionality. For instance, a general arrangement drawing exported as a .dxf file may lose intelligent object properties, rendering it a static graphic rather than a dynamic representation linked to the model.
While exporting to common formats like .dwg can facilitate interoperability with other CAD platforms, this process should be approached with caution. Tekla Structures provides options for customizing the export process to control layer mapping, object representation, and other settings. However, even with careful configuration, some data loss is often unavoidable. A structural steel detail drawing exported to .dwg may require manual adjustment of dimensions, annotations, and line weights to match the original Tekla Structures representation. Moreover, revisions to the original Tekla Structures model will not automatically update the exported .dwg drawing, creating a disconnect between the model and the drawing documentation.
In summary, the choice of drawing file format is a critical consideration when transferring drawings between Tekla Structures models. Utilizing the native .db1 format is generally recommended for preserving data integrity and parametric relationships. When interoperability with other CAD platforms is required, exporting to formats like .dwg can be a viable option, but it necessitates careful configuration and awareness of potential data loss. The optimal approach involves balancing the need for interoperability with the preservation of drawing accuracy and model associativity, considering the implications for long-term project maintainability.
2. Reference Model Association
Reference model association is a critical component in the successful migration of drawings between Tekla Structures models. Drawings in Tekla Structures are intrinsically linked to the 3D model; they are not merely static representations but rather dynamic views that reflect the model’s geometry and attributes. When drawings are transferred, maintaining this association is essential to ensure that the drawings accurately represent the target model and can be updated to reflect any changes in that model. For example, if a drawing detailing a steel connection is transferred to a new model, the drawing must be re-associated with the corresponding connection objects in the new model. Failure to properly re-establish these links results in drawings that are disconnected from the model, rendering them useless for clash detection, revision management, and other BIM-related workflows.
The process of re-establishing reference model association often involves manually re-linking objects or utilizing Tekla Structures’ tools for identifying and correcting discrepancies. If the target model differs significantly from the original model, the manual effort required to re-associate drawings can be substantial. Consider a scenario where a general arrangement drawing is transferred from a model of a commercial building to a model of an industrial facility. The drawing would need to be extensively modified to reflect the new building’s layout, structural components, and object properties. The success of the transfer hinges on the ability to accurately map drawing objects to their corresponding counterparts in the new model, which necessitates a thorough understanding of both models’ structures and object naming conventions.
In conclusion, reference model association is not simply a technical detail but rather a fundamental aspect of drawing transfer in Tekla Structures. The integrity and usability of migrated drawings depend directly on the accuracy and completeness of these associations. Addressing this challenge effectively requires careful planning, meticulous execution, and a comprehensive understanding of both the source and target models. When the appropriate steps are taken to preserve reference model association, the transfer of drawings becomes a valuable tool for streamlining workflows, promoting consistency, and reducing the potential for errors in construction documentation.
3. Revision Control
Revision control is intrinsically linked to the process of exporting drawings from one Tekla Structures model to another. When drawings are transferred, maintaining a clear record of modifications and updates is paramount to prevent conflicts and ensure that the correct version is being used. The act of exporting drawings essentially creates a copy of the drawing at a specific point in time. Without robust revision control measures, it becomes exceedingly difficult to track changes made after the export, potentially leading to discrepancies between the original model, the exported drawing, and the target model. For instance, if a structural engineer modifies a steel connection detail after the drawing has been exported, the exported drawing will no longer reflect the current design, potentially causing errors during fabrication or construction. This necessitates a rigorous system for version management, change tracking, and approval workflows.
Implementing effective revision control requires careful planning and adherence to established protocols. It involves utilizing Tekla Structures’ built-in revision management tools, as well as potentially integrating with external document management systems. The versioning system should clearly identify each iteration of the drawing, noting the date of the revision, the author, and a brief description of the changes made. Furthermore, the process should include a mechanism for flagging drawings that have been exported, preventing unauthorized modifications that could compromise the integrity of the data. As an illustration, consider a scenario where multiple engineers are working on different aspects of a project. Exporting drawings without proper revision control can quickly lead to confusion and errors, as engineers may inadvertently work on outdated versions. A well-defined revision control system ensures that all stakeholders are using the most current and accurate information.
In conclusion, revision control is not merely an ancillary concern, but rather an integral component of drawing export procedures. Its significance lies in preventing errors, promoting collaboration, and maintaining the integrity of the design documentation. By implementing robust revision control measures, organizations can mitigate the risks associated with transferring drawings between Tekla Structures models, ensuring that the exported drawings remain a reliable and accurate representation of the design intent. The challenges inherent in managing drawing revisions underscore the importance of adopting a systematic approach that integrates seamlessly with the overall BIM workflow.
4. Object Representation
Object representation significantly influences the fidelity and usability of drawings exported from one Tekla Structures model to another. The manner in which objects are visualized, encompassing aspects like line weights, colors, hatches, and symbology, directly impacts the clarity and interpretability of the transferred drawings. Discrepancies in object representation between the source and destination models can lead to misinterpretations and errors during fabrication and construction. For instance, if a steel beam is represented with a thick, solid line in the original model but is rendered with a thin, dashed line in the exported drawing, it may not be immediately apparent to the end-user that the element is a primary structural member. This issue underscores the necessity for maintaining consistency in object representation across models to ensure that the exported drawings accurately convey the design intent.
The proper handling of object representation becomes particularly crucial when transferring drawings that contain complex details or annotations. Hatch patterns used to indicate different material types, for example, must be accurately translated to prevent confusion. Similarly, the symbology employed for welds, bolts, and other connection elements must be consistent to avoid ambiguity. Tekla Structures provides tools for customizing object representation through view filters and object properties, enabling users to control how different object types are displayed in drawings. These settings must be carefully configured during the export process to ensure that the resulting drawings accurately reflect the intended visual representation. A practical application involves setting up specific view filters for different drawing types (e.g., general arrangement drawings, shop drawings) to ensure that only the relevant information is displayed and that objects are represented in a clear and concise manner.
In summary, object representation is a critical factor in the successful transfer of drawings between Tekla Structures models. Inconsistencies in object representation can lead to misinterpretations, errors, and rework, negating the benefits of drawing reuse. By carefully managing view filters, object properties, and drawing settings, users can ensure that the exported drawings accurately reflect the design intent and maintain visual consistency with the original model. Addressing the intricacies of object representation is essential for achieving seamless drawing transfers and maximizing the value of BIM workflows in construction projects.
5. Drawing Properties
Drawing properties exert considerable influence on the outcome of transferring drawings between Tekla Structures models. These properties, encompassing attributes such as drawing scales, title block information, and dimensioning standards, dictate the visual presentation and semantic content of the drawings. The process of exporting drawings inevitably involves transferring these properties, and any discrepancies between the drawing properties in the source and destination models can result in inconsistencies, errors, and increased rework. Consider a scenario where a general arrangement drawing is exported from a model using metric units to a model using imperial units. If the drawing properties are not properly converted during the transfer, the dimensions will be incorrect, leading to fabrication errors and potential structural failures. The accurate translation and maintenance of drawing properties are, therefore, paramount to ensuring the integrity of the exported drawings.
The significance of drawing properties extends beyond mere visual representation. Drawing properties also govern how objects are labeled, annotated, and dimensioned. A drawing with improperly configured properties may display incorrect material grades, part numbers, or weld symbols, leading to misinterpretations and potential safety hazards. Tekla Structures provides extensive tools for customizing drawing properties, allowing users to define specific settings for different drawing types and project requirements. However, the complexity of these tools also presents a challenge, as incorrect configuration can have far-reaching consequences. A practical example is the use of custom attributes in drawings. If these attributes are not properly mapped during the export process, critical information may be lost, rendering the drawing incomplete or inaccurate. Therefore, a thorough understanding of drawing properties and their impact on data integrity is essential for effective drawing transfer.
In conclusion, drawing properties form an integral part of the drawing export process in Tekla Structures. Their correct handling directly affects the accuracy, usability, and long-term maintainability of the transferred drawings. By carefully managing drawing scales, annotation settings, and custom attributes, organizations can minimize the risks associated with data transfer and ensure that the exported drawings remain a reliable and accurate representation of the design intent. The challenges inherent in managing drawing properties underscore the importance of adopting a systematic approach that integrates seamlessly with the overall BIM workflow, promoting consistency and reducing the potential for costly errors.
6. Template Preservation
Template preservation plays a vital role in maintaining consistency and efficiency when transferring drawings between Tekla Structures models. Drawing templates define the layout, annotation styles, and overall presentation of construction documents. Retaining these templates ensures uniformity and reduces the need for manual adjustments after the transfer.
-
Layout Consistency
Template preservation ensures consistent positioning of title blocks, revision tables, and notes on exported drawings. If a template is not properly preserved, the layout may shift, requiring manual realignment and potentially introducing errors. For example, a company standard may dictate the placement of a project logo in the upper right corner of all drawings. Template preservation maintains this placement during the transfer, eliminating the need to reposition the logo on each drawing.
-
Annotation Standards
Templates define the fonts, sizes, and styles used for annotations, dimensions, and labels. Preserving these standards guarantees consistent readability and avoids the appearance of non-compliance with project specifications. For instance, if a project requires all dimensions to be displayed using a specific font and precision, template preservation ensures that these settings are carried over to the exported drawings, preventing deviations from the required standard.
-
Custom Object Representation
Drawing templates can include custom object representation settings, controlling how different types of model objects are displayed in drawings. Preserving these settings ensures that steel beams, columns, and other elements are rendered according to the project’s established visual standards. A common example involves using specific hatch patterns to indicate different material types. Template preservation ensures that these hatch patterns are correctly applied in the exported drawings, preventing misinterpretations regarding material specifications.
-
Automated Information Population
Many drawing templates are configured to automatically populate information from the Tekla Structures model, such as material grades, part weights, and assembly numbers. Maintaining this functionality during drawing transfer reduces manual data entry and minimizes the risk of errors. For example, a template may automatically populate the drawing’s title block with the project name and drawing number. Template preservation ensures that this information is automatically updated in the exported drawings, reducing the need for manual editing and ensuring consistency across all documents.
In conclusion, template preservation is not merely a cosmetic concern; it directly impacts the accuracy, efficiency, and overall quality of transferred drawings. By ensuring the consistent application of layout standards, annotation styles, object representations, and automated information, template preservation streamlines the drawing transfer process and minimizes the potential for errors. Ignoring template preservation can result in significant rework and inconsistencies, negating the benefits of reusing drawings across different Tekla Structures models.
7. Clash Checking
Clash checking assumes a crucial role when transferring drawings between Tekla Structures models. The process of migrating drawings introduces the potential for discrepancies between the drawing’s representation of the design and the actual model, particularly if the drawing is not properly updated or re-associated with the target model’s objects. Effective clash checking, therefore, becomes essential for verifying the accuracy and constructability of the exported drawings within the context of the destination model.
-
Detection of Geometric Conflicts
Clash checking identifies geometric interferences between different components represented in the drawings. If a drawing details a connection that clashes with other elements in the target model (e.g., a beam clashing with a duct), clash checking reveals these conflicts. An example involves transferring a drawing of a steel connection that interferes with a pre-existing concrete column in the destination model. Clash detection alerts the user to this geometric incompatibility, prompting corrective action. This has direct implications for the constructability of the design.
-
Verification of Tolerances and Clearances
Drawings often specify critical tolerances and clearances for various components. Clash checking verifies that these tolerances are maintained within the context of the destination model. If an exported drawing depicts a pipe with insufficient clearance from a structural beam, clash detection identifies this violation. A real-world scenario involves a drawing of a mechanical system transferred to a new model, where it is discovered that the specified pipe clearances are not met due to changes in the building’s structural design. This emphasizes the importance of clash checking in ensuring compliance with design requirements.
-
Validation of Drawing Accuracy
Clash checking validates the accuracy of the exported drawing in relation to the model it represents. If the drawing contains outdated information or inconsistencies with the current model geometry, clash detection can highlight these discrepancies. Consider a drawing that depicts a steel beam in the wrong location compared to its actual position in the model. Clash checking reveals this misalignment, prompting the user to update the drawing accordingly. This aspect of clash checking ensures the drawing accurately reflects the current state of the model.
-
Coordination Across Disciplines
Clash checking facilitates coordination between different disciplines involved in the project. When drawings are exported between models representing different disciplines (e.g., architectural, structural, MEP), clash detection helps identify conflicts between elements designed by different teams. For example, an exported architectural drawing may depict a wall that interferes with a structural column in the structural model. Clash checking brings this conflict to light, enabling the teams to coordinate and resolve the issue before construction. This promotes collaboration and prevents costly rework during the construction phase.
In summary, integrating clash checking into the drawing transfer process is vital for ensuring the accuracy, constructability, and coordination of exported drawings. By identifying geometric conflicts, verifying tolerances, validating drawing accuracy, and promoting cross-disciplinary coordination, clash checking helps mitigate the risks associated with drawing migration and enhances the overall quality of the project. Its application is critical in preventing errors and improving efficiency in construction workflows.
8. Drawing Numbering
Drawing numbering schemes are intrinsically linked to the efficient export of drawings from one Tekla Structures model to another. A well-defined numbering system provides a unique identifier for each drawing, facilitating organization, retrieval, and revision control during and after the transfer process. The absence of a coherent numbering system can lead to confusion, duplication, and difficulties in tracking drawing versions, significantly impeding the effectiveness of drawing export workflows. Consider a project where drawings lack consistent numbering. When exporting these drawings to a new model, it becomes difficult to determine which drawings are the most current, whether any drawings are missing, and how to properly organize the transferred drawings within the new project structure. This lack of order can result in errors and delays in downstream processes, such as fabrication and construction.
Drawing numbering impacts the reference model association. When exporting drawings, the links between drawing objects and model objects must be maintained. Proper drawing numbers help ensure these associations remain intact, particularly if the target model uses a different object numbering system. The drawing number serves as a stable identifier that bridges the gap between the source and destination models, minimizing the likelihood of broken links and misaligned objects. For example, if a drawing details a specific steel connection identified by a unique object number, the drawing number provides a consistent reference point for locating the corresponding connection in the target model, even if the object numbering schemes differ. This illustrates the practical significance of using drawing numbers as a mechanism for preserving the integrity of drawing-model relationships during the export process.
In summary, drawing numbering is not simply an administrative detail; it is a fundamental component of an effective drawing export strategy. A well-designed numbering scheme enables efficient organization, facilitates revision control, and preserves drawing-model associations. By prioritizing drawing numbering in drawing export workflows, organizations can minimize the risk of errors, streamline processes, and ensure the long-term maintainability of their construction documentation. Challenges in implementing consistent drawing numbering often stem from project-specific requirements and legacy data structures, underscoring the importance of establishing clear and well-defined numbering protocols early in the project lifecycle.
9. Custom Attributes
Custom attributes within Tekla Structures models constitute user-defined data fields attached to various model elements, including drawings. Their proper handling is critical when transferring drawings between models to maintain data integrity and project-specific information.
-
Data Preservation
Custom attributes embedded within drawings often contain essential project information not found in standard Tekla properties. This data includes approval statuses, fabrication notes, or specific material specifications. Failure to transfer these attributes results in the loss of valuable information, potentially leading to errors and rework. A practical example includes custom attributes designating specific weld procedures required for a connection. If these attributes are not properly transferred, fabricators may use incorrect welding techniques, compromising structural integrity. This facet underscores the importance of preserving custom attributes to maintain the semantic content of drawings.
-
Drawing Organization
Custom attributes frequently drive drawing organization and filtering within Tekla Structures. These attributes may be used to categorize drawings by discipline, building area, or revision status. If these organizational attributes are not correctly transferred, drawings may become misplaced or misclassified in the destination model, impeding efficient retrieval and management. For instance, a custom attribute may identify drawings belonging to a specific phase of the project. Without proper transfer, these drawings become difficult to locate, increasing the risk of overlooking critical documentation during construction. This illustrates the crucial role of custom attributes in maintaining drawing organization and accessibility.
-
Report Generation
Custom attributes are commonly used in report generation for extracting project-specific data from drawings. This data may include quantities of materials, lists of required inspections, or summaries of fabrication requirements. If these attributes are lost during the drawing transfer, the generated reports will be incomplete or inaccurate, hindering effective project management. A typical scenario involves using custom attributes to track the progress of steel fabrication. If these attributes are not transferred, the ability to monitor the fabrication status accurately is compromised. The dependency of reporting functions on custom attributes emphasizes the necessity of their reliable transfer.
-
Automation and Scripting
Custom attributes enable automation and scripting within Tekla Structures. User-defined scripts and macros often rely on custom attribute values to perform specific tasks, such as automatically generating drawing views or updating drawing properties. If these attributes are not preserved during drawing transfer, the automation functionality will be impaired, requiring manual intervention and potentially introducing errors. As an example, a script may use a custom attribute to automatically set the drawing scale based on the size of the object being detailed. Loss of this attribute will prevent the script from functioning correctly, requiring manual adjustment of drawing scales. This dependence of automation processes on custom attributes demonstrates their importance in maintaining efficient drawing workflows.
The seamless transfer of drawings between Tekla Structures models necessitates meticulous attention to custom attributes. These user-defined data fields encapsulate project-specific information, drive drawing organization, enable reporting functionalities, and facilitate automation. By prioritizing the preservation of custom attributes, users can mitigate the risks associated with data loss, maintain drawing integrity, and ensure efficient project execution.
