Draft

Description

Usage

Notes

• Non-Draft objects that are totally planar can also be converted.
• The command can only handle objects made up out of straight lines, circular arcs, elliptical arcs, B-Splines and Bézier curves.
• Draft BezCurves will be approximated by Sketcher BSplines.
• The external KicadStepUp Workbench contains a command to convert a Draft BSpline into a series of Sketcher Arcs. For more information see the forum topic BSplines to Shape2DView and Sketcher.
• This other forum topic contains a macro for such a conversion.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

To convert objects to a sketch use the make_sketch method (introduced in 0.19) of the Draft module. This method replaces the deprecated makeSketch method.

sketch = make_sketch(objects_list, autoconstraints=False, addTo=None, delete=False, name="Sketch", radiusPrecision=-1, tol=1e-3)

• objects_list contains the objects to be converted. It is either a single object or a list of objects. Draft objects, Part::Feature objects and Part.Shape objects are supported.
• If autoconstraints is True coincident constraints are added to nodes belonging to the same source object.
• addTo is the existing sketch object the geometry is added to. If not supplied a new sketch is created.
• If delete is True the source objects are deleted.
• name is the name for the new sketch.
• radiusPrecision indicates how radius constraints should be handled:
  • Use -1 to disable radius constraints.
  • Use 0 to add individual radius constraints.
  • Use a positive number to round radii according to this precision, and to add equal constraints between curves with equal radii.
• tol is the tolerance used to check if shapes are planar and co-planar. Use -1 for a strict analysis.
• sketch is returned with the sketch object.

To convert a sketch to Draft objects use the draftify method of the Draft module.

draftify(objectslist, makeblock=False, delete=True)

• objectslist contains the objects to be converted. It is either a single object or a list of objects.
• If makeblock is True the converted objects are grouped in a Part::Part2DObject.
• If delete is True the source objects are deleted.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

rectangle = Draft.make_rectangle(2000, 1000)
circle = Draft.make_circle(500)
doc.recompute()

sketch_from_draft = Draft.make_sketch([rectangle, circle], autoconstraints=True, delete=False, radiusPrecision=0)
doc.recompute()

draft_from_sketch = Draft.draftify(sketch_from_draft, delete=False)
doc.recompute()
