We had a member ask about the availability of a model for an Continental O-300 engine that they can drop into an aircraft design. Continental has agreed to provide 2D models in a GP4 or PDF file. I have two questions. First, is GP4 importable into SOLIDWORKS. Second, does anyone have a 3D sand-filled solid model of this engine that they can share so that it doesn't have to be redrawn? Thanks!
