If erasing those edges removes faces, your faces aren’t in the same plane. Very likely the best fix is to start over and make it correctly so those faces are planar and those edges can be removed. What is it supposed to be?
Remaking it kind of defeats the purpose, moving them section by section would be a lot faster. I was curious if it was possible to make it all one piece so I can push the side in for the whole unit. This is a bracket. I had success welding it at one point but I couldn’t replicate it for the other sections and now the weld wont take at all.
It’s just by eye from your image, but it looks like the long part isn’t on the same plane as the little squares at its ends. There looks like a small bevel if you look closely at the top or bottom edge.
Brilliant!!! Thank you. In regards to your upload request, what is the preferred export file type? This is like the 2nd thing I have ever made on sketch up, please excuse my ignorance. Looks like I can choose png or stl
