Описание

Инструмент GeometricHatch заполняет замкнутый регион внутри вида шаблоном, базирующимся на спецификации AutoDesk PAT hatching. В качестве альтернативы, инструмент Hatch использует качестве рисунка штриховки файл в формате SVG или растровый, подробности см. в Hatching.

Геометрический узор штриховки на грани

Использование

  1. Select an closed region in a View.
  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.

Примечания

  • 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.

A small set of sample patterns are available in:

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

$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.

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)

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)
