Hi

I’m new to Shapr3D so apologies if this answer is covered elsewhere - I’ve spent a long time looking through the tutorials, have Googled and not found a solution.

I’m creating a design that involves duplicate parts (fairly complex). I want changes applied to one of the parts to automatically apply to duplicates. What’s the simplest way to accomplish this?

Thanks for any help!

Unfortunately we don’t have “instancing” yet, meaning that there isn’t any relationship between duplicates. The bst way ot achieve it is to duplicate again the modified part.

I really hope that this feature is added soon.  
I just bought Shaper3D and have a case where i want to change the mortise locations on my table legs and was disapointed as to how I have to do this with Shaper as opposed to other design packages.
