When you are starting to work on a new project, most of the time you will start form an existing one.
In your source product wou will probably have :
- Full 3D definition of your product(asm and prt)
- All requested drawings (drw)
- Probably inherited models for industrialization
- Manufacturing objects (mfg)
the issue today is that you want to duplicate all these objects in 1 click, but collectors are not able to collect MFG and inherited models, which leads to a lot of troubles to do a basic save-as.
