Auto Assembly add-on creates product types and assembly type for process modeling using existing components, nodes or features as a source. Add-on requires VC 4.4 or newer as on 4.4 there were new APIs introduced to access assembly types. Add-on package includes PDF instructions on how to use the add-on. There are few demo videos of different use cases.
Add-on has been updated so that it works also in 4.7. As there were some changes to product filters in 4.7 the old version of this add-on didn’t work anymore. Now the code has been updated, see the attachment in original post.
This version should work in 4.9. If you don’t see the button in 4.9 you could double check that the add-on is under “My Commands\Python 2” folder. Context for this here:
If you get some error when running the add-on could you post it here so I can debug it?
