Q3D to STL Conversion: FAQ

What are Q3D files?

The Q3D format is associated with QuickDraw 3D or QD3D, a program initially launched in the mid-1990s for Macintosh computers. The program offered a series of features for 3D graphics design, but registered modest popularity. Starting with the late 1990s, Mac applications for 3D graphics became based on OpenGL, a cross-platform programming interface more widely used by similar applications.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems.
