Description

The Geometric Hatch tool fills a closed region in a TechDraw View with a pattern based on an AutoDesk PAT hatching specification.

Geometric hatch pattern on a face

Usage

Select an closed region in a View. The region will turn green.
Press the GeomHatch button
a dialog will open where you may select your pattern, a scale for the pattern and a line weight.
You may need to press recompute and/or "wiggle" the parent View to get the pattern to update.

Notes

Hatching objects are vulnerable to "topological naming" issues. See the information in the TechDraw Dimension Length tool for more information. It is recommended that hatching be one of the last steps in your drawing process.
Unlike the Hatch tool, geometric hatch patterns are included when a drawing page is saved as an SVG file.

A small set of sample patterns are available in

$INSTALL_DIR/Mod/TechDraw/PAT/FCPAT.pat

where $INSTALL_DIR is the directory where FreeCAD was installed, for example

/usr/share/freecad/Mod/TechDraw/PAT/FCPAT.pat

Properties

DataSource: The View and Face to receive the hatch pattern.
DataFile Pattern: The location of the PAT file to use.
DataName Pattern: The name of the PAT specification within File Pattern.
DataScale Pattern: The scale to be applied to the pattern (must be > 0.0).
ViewWeight Pattern: The thickness of the pattern lines.
ViewColor Pattern: The color for the pattern lines.

Scripting

The GeomHatch tool can be used in macros and from the Python console by using the following functions:

hatch = FreeCAD.ActiveDocument.addObject('TechDraw::DrawGeomHatch','GeomHatch')
hatch.Source = (view1,["Face0"])
hatch.FilePattern = "path/to/myPATfile.pat"
hatch.NamePattern = "Diamond"
rc = page.addView(hatch)
