Описание

Геометрический узор штриховки на грани

Применение

1. Select a closed region in a view.
2. There are several ways to invoke the tool:
   • Press the Geometric Hatch button.
   • Select the TechDraw → Hatching → Geometric Hatch option from the menu.
3. The Geometric Hatch task panel opens.
4. Optionally change the Pattern file, the Pattern name, the Pattern scale, the Line width, the Line color, the Rotation, the Offset X and the Offset Y.
5. Press the OK button.

Примечания

• For a solid color fill use TechDraw Hatch instead and select solid.svg as the Pattern File.
• Hatching objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension for more information. It is recommended that hatching be one of the last steps in your drawing process.
• A small set of sample patterns are available in:

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

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

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

Свойства

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

Программирование

A GeometricHatch can be created with 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"
page.addView(hatch)

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:

import TechDraw
face = Part.makePlane(10, 10)
patfile = "path/to/myPATfile.pat"
pattern = "Diamond"
scale = 10
hatch = TechDraw.makeGeomHatch(face, scale, pattern, patfile)
Part.show(hatch)
