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.
TDR v3.x format: Files apparently start with bytes

TDR old format: Undetermined. Note that files start with three length-prefixed text fields.
