How to Disconnect vertices/Remove unnecessary edges inside mesh?

Hello!

I’m new to blender, so please forgive me if I say something dumb.

I’ve been trying to make a map in blender. I imported an SVG file and followed a YouTube guide, already applied Decimate modifier to clean up the messy edges, converted the curve to mesh, and my map still ended up with these edges across the map.

Dissolving vertices or edges doesn’t do anything, and deleting these connected vertices/edges only removes the face and everything in it.

Can someone tell me what I did wrong here and how do I remove these edges that are inside the mesh?

Thank you very much!

NGons, (faces with more than 4 vertices) need those edges when there are holes in the faces.

Those edges cannot be removed, because a face cannot have a hole in its middle. You need to use multiple faces here. The best you can do is to put them in areas where they look nice, if that’s important to you. In other words, you can remove those edges only if you add additional ones somewhere else so the hole doesn’t end up floating in the middle of a single face.

Thank you. I didn’t know that. I tried adding some more faces and everything worked out. Thank you!

Thank you for the information! Helped me understand it better :smile:
