I can't seem to make a "Face" on the surface of my model

What Box wrote. I welded the edges.

By the way, edit the style and set the Profiles to 1. It’ll make errors like your face dividing edge easier to spot.

ok got it, i think my version needs to be updated to see Weld in the menu, just updating now.

Let me throw another curve ball at you, i also want to make this mounting plate like a 45deg angle wedge (if that makes sense). Can you pull a surface around an axis for example?

Not to get what you probably want.

Which direction and do you really want to cut it at 45°?

it doesn’t have to be exactly 45, something around that.

Do you mean like this, or something else?

Use the Solid Tools.

yes, exactly this. Although thinking about it, those 4 screw holes would need to be at right angles to the top surface

Cut off the bottom, then.

of course. I’ll leave you guys alone. Super impressed, thank you.

45 is quite steep but…
You can always offset the holes so they have flat tops.

Hi Box, can you explain how you made the holes go through the solid and created the flat tops?

I made the cut in the wrong place, but I’m sure you get the idea.

Perfect. Turns out i dont need those flat tops anyhow.
