TechDraw Hatching/en

Description
The TechDraw workbench has two hatching tools:
 * [[Image:TechDraw_Hatch.svg|32px]] Hatch Face using Image File (tile based)
 * [[Image:TechDraw_GeometricHatch.svg|32px]] Apply Geometric Hatch to Face (line based)

Usage
Result: The face will be hatched initially using default values. Note: Edit the hatch properties to get the desired pattern.
 * 1) Select a Face
 * [[Image:SelectFace.png|150px]]
 * 1) Depending on the need, press either [[Image:TechDraw_Hatch.svg|24px]] Hatch Face using Image File or [[Image:TechDraw_GeometricHatch.svg|24px]] Apply Geometric Hatch to Face icons.

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

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

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

The default hatch pattern file can be specified in the 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.

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