  Rotating and Aligning Elements in MLCad
 
Hey Y'all: I know this is answered elsewhere, but it's a hassle to look for. As great as MLCad is (for me it is "THEE" CAD tool for LDraw action), the documentation is just not there in some ways. Recently I had cause to mess with an angled element (...) (24 years ago, 12-Sep-02, to lugnet.cad.mlcad)
