Description

The GeometricHatch tool fills a closed region in a View with a pattern based on an AutoDesk PAT hatching specification. Alternatively, the Hatch tool uses an SVG or bitmap file as hatch pattern, see Hatching for details.

Geometric hatch pattern on a face

Usage

  1. Select an closed region in a View. The region will turn green.
  2. Press the Apply Geometric Hatch to Face button
  3. A dialog will open where you can select your pattern, the scale, line weight and color.

Notes

A small set of sample patterns are available in:

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

$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

See also: TechDraw API and FreeCAD Scripting Basics.

The GeometricHatch 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)
