The drawing manager uses the current bill of material (BOM) to create tube and pipe drawings. When you migrate R9 or earlier tube and pipe drawings, specify whether to use the R9 BOM (default) or the current BOM.
The BOMs differ in how they store the raw material description for library parts:
- In the current BOM, the raw material description for conduit parts is stored in the new stock number property. All BOM items with the same part number are automatically merged in parts lists. If the part number is blank, parts do not merge
- In the R9 BOM, the raw material description for conduit parts was stored in the part number property. You had control over the merging of rows in the parts list. If two pipes had the same part number, you could choose not to merge them.
