For your blue object, it is possible to remove that edge using boolean union which will merge faces that are coplanar.

Select this face:


Use Edit > Separate to break it off as a separate object, then select the 2 pieces and run Construct > Boolean > Union.

Or another way - you could delete those 2 faces and prepare a selection like this and use Construct > Planar:

That worked great — thanks for showing both of these techniques! I didn’t know that curves could be used for Booleans like that — I always thought it only worked with solid objects.

I used some Booleans to trim the rounded shapes, and I think that caused a lot of broken edges — tiny segments. I can join them, but whenever I separate the edges again, they split into all these little pieces.

Is there a way to merge or “Boolean” these edges together somehow, to get a cleaner model? It gets very tricky to apply a Fillet or Chamfer to these tiny bits. I’ve tried creating Closed Curves from the edge outlines, but I can’t seem to use them to generate a Fillet.

Thanks again,

Hi Frederik,

You can use the Merge command for that:
https://moi3d.com/4.0/docs/moi_command_reference10.htm#merge

Select the whole object, type the Tab key to put focus in the bottom XYZ input, then type Merge <enter> and those fragmented edges will be combined.

A curve is its own separate object, it isn't connected to the solid.

To make a fillet on the solid you need to select edges which are part of the solid, not separate curve objects.

Thanks for explaining curves vs edges. I'm starting to understand the modeling process better. The Merge command worked great, thanks!
