8.6.8. Additional models open when creating a drawing with Module 4

In this guide, you will learn why additional DWG files are automatically opened during drawing derivation with SuCri Module 4. This background knowledge will help you better understand how the software works and increase the efficiency of your project creation.

Prerequisites

The SuCri Module 4 plugin is installed in your system environment.
You are in the process of drawing derivation for a Support-Unit (SU).

Step-by-Step Instructions

Start the drawing creation for a specific Support-Unit (SU) as usual via Module 4.
Observe the process in AutoCAD/Plant 3D. During creation, you will notice that several DWG files open in the background.
In these files, there may be, for example, pipelines, structures, or other plant areas.
Expected Result: The system processes this data automatically to generate a complete view and bill of materials (BOM).
Wait until the drawing derivation process is complete.
Expected Result: The additionally opened files are usually automatically closed again after the creation is finished or can now be closed manually.

Important Notes

Background of this behavior: This procedure is not an error but is intended by the system. The files are indirectly connected to the SU because they are either attached as XREFs (external references) or contain objects that are referenced in the SU model.
Performance: For reasons of performance and data integrity, SuCri opens these linked DWGs to correctly calculate weights, references, and bills of materials.
Additional Objects: If additional pipeline objects appear in the drawing, this results from the Plant 3D BOM configuration.

Troubleshooting

Problem: Too many or unwanted files are being opened.
Solution: Check the SU file for unnecessary XREFs or outdated project links. Remove unneeded references to keep the number of automatically loaded models low.
Problem: The bill of materials contains unexpected pipeline objects.
Solution: Adjust the Plant 3D BOM configuration specifically for the project if certain object classes should not be included.
