I'm running openscad nightly on Ubuntu18. I am importing an STL and performing an intersection. The GUI performance is terrible. I drag the mouse and it takes a couple seconds for anything to happen, and the movement is large and difficult to control. >> Are there settings i can change to improve performance? codeblock: CHOPBLOCK=[115,300,320]; intersection(){ import(FILENAME,convexity=10); cube(CHOPBLOCK); }

You can wrap a render() around it so the result is calculated once with CGAL and then it will be fast to draw. Also in development snapshots you can turn on vbo rendering and that is much faster. If the STL is slow to draw I expect it has many facets and that might be a problem for CGAL. You might have to reduce the number of facets in another program.
