Yup, I definitely agree!

The reason why it hasn't been added yet is not because I don't think it would be a good and useful feature, but just because it is not an easy thing to implement and will take some hard work to enable it.

Hi NightCabbage,

> It's pretty intuitive, so that's good (no idea why it didn't work before!)

Well, if you select the edge while you still have that blue surface in place, it won't delete. Untrim only works on edges that are not connected to other things, so you have to delete the blue surface first before having an open hole there... Maybe that was what you ran into?

Quite possibly :)

So general rule:

You can always delete surfaces, but you can only delete lines that don't have any dependant objects (like a surface).

Hi NightCabbage, yes that is correct.

Also to delete edges you need to select the entire loop that forms the trimming boundary. Like for example if you have a square hole with 4 edge making up the hole you have to select all 4 of those edges to delete, not just one of them.
