Preform - How to delete Hole edit

I have a model that I have made Hollow and now I need to add holes to help prevent cupping.

I add a hole and click Apply Edits and it works, but how do I delete that hole later?

All I know to do right now is right click and replace the entire object and start all over.

If you have saved and closed the file and then opened again you can not edit the holes any more.
If the file is still open you can edit the holes. Go to Hole and select the object with the holes you made. The cylinders that make the holes should be orange. Click on the desired cylinder. It turns blue. Click delete in the “hole window”. done.

Hi Revel,

Yes, Klaus is correct, but thank you for the feedback on non-destructive mesh editing processes. I will pass the note on to the rest of the product team as we continuously improve PreForm.

I’ve taken to copying the mesh before adding holes or texturing. That way I have a “clean” copy I can toggle off and have as a backup. This is especially valuable with texturing, as textures seem to be cumulative. You add a new texture, and it applies over the first, rather than to the original surface.

Great temporary solution. In case you’re saving these copied “clean plate” meshes as .form files locally on your disk, you could copy them within the same scene and toggle the eye icon next to the Model List row, rename it to indicate it was before adding a hole/texturing, and anything hidden will not slice or print. This way you can have an almost-timeline without having to import and export separate .form files entirely

That is currently how I do it. Both the backup and the edited mesh are objects in the .form file, not “exterior” models.
