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
Применение
- Select an closed region in a View.
- Press the
Apply Geometric Hatch to Face button - A dialog will open where you can select your pattern, the scale, line weight and color.
Примечания
- 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
$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
См. так же: TechDraw API и Основы составления скриптов FreeCAD.
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)
