Assignment mode - there is no toggle!



I’m trying to hand in an assignment for a webinar workshop.
Unfortunately I’m stuck at a mesh refinement process:
I added a mesh refinement, when I try to add faces to be refined I cannot select anything (the box with the selected faces stays empty…) The problem is, that there is no toggle to switch on the auto-add (as also presented as a new feature)

Can you please help me?
thank you very much in advance


Hello @mathias2
can you share your assignment with me so that i can look at it and let me see if i can be able to help you



Of course,
here is the link to my project

I found out, that the problem exists also with other projects - I just cannot add faces to a selection.
Thank you


Hello @mathias2,

you are trying to select refinement regions on a finished mesh. This is not yet supported. Therefore the assignment box does not allow you to add entities.

In order to assign the refinement faces you need to delete the result of the mesh operation first and then select the faces on the geometry again. If you want to keep your current coarse mesh you can simply duplicate the operation. The screenshots below show how to proceed from your current status:

The UX of this work flow is right now not on the level that we want to provide. We are investing to make the assignment simply also work on the finished mesh. Until that point you need to unfortunately stick to the proposed work around. Please not though that this is not related to the new assignment workflow. Mesh refinements were not possible on the finished mesh result in the past as well.

Hope that helps!

Best regards
