Hi, I’ve been having this problem for a while now. I use make2d command often, saving as a dwg and opening in either autocad or illustrator. I am careful to make sure all of the objects I am capturing are in the viewport because I know make2d can get confused when objects are behind the camera. I have also tried playing with the different options for polyline, natural, etc.
The make 2d lines appear as they should in rhino but once I open them in another program strange things happen. Some of the lines seem to be scaled many times larger than the others while the bulk of the drawing is a minuscule speck in the corner of the illustrator window. Below is a link to a dwg that has this problem. I am using rhino 4 SR9.
Thanks,
David
