Description: Gear Factory allows you to easily add standard or custom gears to your Drawing. The gear models created are standard AutoCAD solid models that can be added to your assembly drawing as 3D model or 2D entities. It's like having a gear factory on-line that can create spur, bevel, internal, rack gear and roller chain sprockets from your data input. You just select the pitch, pressure angle, number of teeth, width, and insertion point.
