How to remove all stray lines / surface mess and fix the structure


Hi Community,

I got a shape I imported from STL that has lots of stray lines and overall mess,
I am trying to remove lines one by one but it’s tedious, so I was wondering, is there a way to remove all useleff stuff from the shape and keep only the … actual shape?

After I manage to do this I will pull it to 3D, make it solid and then 3D print it, but all these lines… arghhh.

First thing I always do with imported STL files is run Thom Thom’s CleanUp3. That generally gets rid of all the unneeded coplanar edges.


Worked like a charm. Thank you very much!
