TechDraw GeometricHatch

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.



Usage

 * 1) Select an closed region in a View.
 * 2) Press the  button
 * 3) A dialog will open where you can select your pattern, the scale, line weight and color.

Properties

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

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

It is also possible to use TechDraw's geometric hatch engine to produce a compound object in the 3D space. One must take care that the base face lies on the XY plane, as the algorithm is not tailored yet for other cases:
