Descrizione

Lo strumento Tratteggio geometrico riempie una regione chiusa in una vista con un modello basato su una specifica di tratteggio PAT AutoDesk. In alternativa, lo strumento Tratteggio da modello utilizza un file SVG o bitmap come modello di tratteggio, vedere i tipi di tratteggio per i dettagli.

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 may select your pattern, a scale for the pattern and a line weight.
  4. You may need to press Refresh and/or Redraw Page to get the pattern to update.

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

  • DatiSource: The View and Face to receive the hatch pattern.
  • DatiFile Pattern: The location of the PAT file to use.
  • DatiName Pattern: The name of the PAT specification within File Pattern.
  • DatiScale Pattern: The scale to be applied to the pattern (must be > 0.0).
  • VistaWeight Pattern: The thickness of the pattern lines.
  • VistaColor 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)
