How to reduce vertex count on a mesh I need a way to fix this mesh.
It has way too many faces and when I import the .stl file to other programs it gives me a broken polygon message. I want to 3D print this object in matter control once I fix the problem.
Select all vertices, hit X button and select Limited Dissolve from the menu.

 

Then hit F6 button and adjust Maximum Angle to get desired result. 



Then to triangulate the mesh hit Ctrl+T shortcut.
