Change .dwg for Dwg Underlay

[Jos_Heruvent]

I want to import a dwg into an Inventor .ipt.
If I modify the dwg by stretching or moving and I update my part everything goes well. The extrude goes well. But if I add or remove something in the Autocad .dwg and update my Inventor .ipt then it goes wrong. The dwg underlay is not updated properly. The things I removed or added are not taken over properly. The changes in the dwg are visible but the new extrude is not taken over properly. The old sketch remains present. I first have to delete it and then run Project DWG Geometry again and select the modified dwg again. Even then I have to run extrude again.
Does anyone have experience with this or is this just not possible, yet.

Can you record a video so we can see what you are seeing?

I see now, I always just assumed that was the nature of it since the trimming and all. I guess I just thought it would lose the references by default.

Hi! Yes, the associativity will work well when the underlying source geometry changes sizes, not deleting. When the source geometry is deleted, Inventor will not know how to redefine the profiles. The user will have to repair the errors.

Many thanks!
