Editing a T-Spline or Surface after using solid tools

[Anonymous]

Hey all,

Newbie question here. I'm making a facemask that has a freeform, rather amorphous shape and thus I have to use the T-Spline tools. However, my model also has some hardware cutouts that have to be done with the solid modelling tools. My issue is that I can't figure out how to setup my Form so that I can push-pull edit the mask shape without deleting the design history. Please advise, and thanks in advance! (Pic below for reference).

@Anonymous - can add some more details about what you are trying to do when you say "so that I can push-pull edit the mask shape without deleting the design history."?  Are you trying to go back and edit the T-Spline form?  Or, are you expecting that the Press/Pull command can work in the Solid environment?  I would not expect to be able to do anything meaningful in the Solid environment.  But, you should be able to edit the Form feature and modify the shape in the T-Spline environment, and on exit, all your cutouts should compute based on the newly edited result.

Hi Jeff, 

Thank so much for the timely response! Yes, I'm trying to go back and edit the T-Spline itself. I was able to do this in a new file, however, in my current one it doesn't seem to work. I have a thickened T-Spline body, and when I select capture design history, it automatically converts to a solid. Once there, I can't seem to edit the T-Spline without turning off design history. I'm fully aware that this is probably user error haha. Thanks so much for your help.

can you share the design here?  Not really sure what the problem would be from that description.  If the design was not history-based in the beginning, there may be issues with trying to convert it to be history-based, but I'm not certain.  If we can see the file, it will help a lot.  Thanks.

Absolutely, here you go:

Thanks, @cjtman.theriault - this design looks OK to me - I'm able to edit the T-Spline by just right clicking and choosing "Edit", making modifications, then exiting from the Form environment.  This is how I expect a history-based design to work, so the conversion from a Direct Model seems to be OK.

Got it, thanks! I was missing the fact that the T-Spline body is accessible in the newly created design history. Thanks so much!
