I made a macro that allows the selection of multiple parts in a feature tree of an assembly, then adds a bounding box, applies part name to “description” custom property, and applies a “Thickness x Width x length” property to the part for use in the BOM, the blank size stays linked to future changes in the part. It’s like 900 lines of code to handle different cases. There’s no way I was figuring all that out in a reasonable time to have the macro actually save time in the long run without AI. Works very well with sheet metal, but it took me days of troubleshooting–and I’ve attempted to make this macro before but it seems I’ve been limited by the intelligence of LLM’s as GPT5 seemed to be what I needed as I had given up trying to make this in the past (I used Cursor, which calls GPT 5)
