You can use this feature to generate BOMs for AutoCAD drawings and AutoCAD Mechanical toolset drawings without BOMs.
A parts list that has been typed in manually, is referred to as a manual parts list. The following are examples of manual parts lists:
If you have drawing project where the parts lists in assembly drawings have been typed in manually, the Parts List Migration tools in AutoCAD Mechanical toolset can:
If the parts list is a Microsoft Excel spreadsheet, the tools generate the BOM, but do not place a parts list in the drawing.
If the drawings are part of a project where each part and subassembly is drawn in its own DWG file, the migration tools do not stop at generating BOMs. They go on to discover the hierarchical relationship between the drawings and link their BOMs using the BOM attach workflow.
If the drawing project is a non-AutoCAD Mechanical toolset drawing project (for example, an AutoCAD drawing project), the migration tools does the following as well:
(The drawing is migrated so that it can hold a BOM).
