TechDraw Hatching

Overview
TechDraw has two hatching tools: Hatch Face using Image File (tile based) and  Apply Geometric Hatch to Face (line based).

For either tool, select a Face,



then press the appropriate icon. The face will be hatched initially using default values. Edit the hatch properties to get the desired pattern.

Hatch Face using Image File
Hatch Face using Image File uses SVG or bitmap bases tiles to cover the selected Face.

SVG tiles are typically 64x64 pixel images. Some examples are available on GitHub.

Any bitmap file can be used (png, jpeg, etc) as a fill. Results are best with many small repeated images rather than fewer larger images.

Default Hatch fills can be specified in TechDraw Preferences.

Geometric Hatch
Apply Geometric Hatch to Face forms a pattern of lines based on a specification read from a file. This file is generally compatible with the widely used AutoDesk® PAT format. A small selection of patterns is included in the FCPAT.pat file:

You can add your own patterns if you have write permission to FCPAT.pat, or you can create your own *.pat file and point to it in TechDraw Preferences.
