TechDraw Hatching

Description
The TechDraw workbench includes two hatching tools:
 * [[Image:TechDraw_Hatch.svg|32px]] TechDraw Hatch (based on tiled SVG images)
 * [[Image:TechDraw_GeometricHatch.svg|32px]] TechDraw GeometricHatch (line based)

Image based hatch
TechDraw Hatch uses tiled SVG images to cover the selected Face.

SVG tiles are typically 64x64 pixel images. All pattern files that come with FreeCAD are available on GitHub.

The default hatch pattern file can be specified in the TechDraw Preferences.

Geometric hatch
TechDraw GeometricHatch 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.

PAT File Path
The file can be found in the following location.
