Top Draw is a vector graphics editor for Windows 3.1. It was developed by Top Software, of Conifer, Colorado.

It has a native .TDR vector graphics file format. It also has a .TDS "Shapes" file format (a vector-based clip art library).

There was a major change to the TDR format at some point, apparently at v3.00.
