In the design archives are a number of interesting non-traditional frames. Folders, penny-farthings, curved seat tubes, an X-frame, Notably several by cronjewv. When I try to open these in bikecad, the java applet just hangs.
Are these only available for the pro version? If so, what are the limitations on geometry supported by the pro version? I have some rather eccentric ideas for bikes, and if the pro version could handle them, it would be worth the money rather than spending the time it takes to draw them in Draftsight.
