This is added to conveniently change the face maker type of an extrusion object.
Hint: A new property is used to avoid to break project files when opening it with an older version.
This PR adds the same functionality as provided by Part Extrude.
The used code parts are sorted out to a new helper function that is used by Part and PartDesign.
- there can be strange cases with structures all intersecting each other. Their extrusion has no practical use case but we must avoid that such structures results either in an infinite loop or in an invalid geometric result.
* Added Part::Feature::getTopoShape/getShape() function that can obtain
shape from any object with proper implementation of getSubObject(). It
can even construct compound from group object with proper implementation
of getSubObjects().
* Modified ViewProviderExt to work on any object, because it now obtain
the shape using Part::Feature::getShape()
* Modified various Part features to obtain base/tool shapes using
Part::getShape(), which allows them to be any type of object,
including Link and groups.
* Modified various Part command to relax type requirement on selected
objects.
* Add support of link and group to dimension, and add dimension refresh
command
* Support link and group in simple command command, and add a few more
copy command variations.
* Add special handling of 'Shape' attribute in PropertyContainerPy and
use Part::Feature::getShape() to return shape for any object without
Shape property. This allows many python feature work with any object
without modification.
* GeometrySurface/CurvePy, add convenience attribute 'Rotation'
* TopoShapePy:
* Extended support of sub shape attribute, e.g. Compound1, Solid2,
SubShape3 ('SubShape' is used to access child shape of a compound)
* makeWires(), new API to sort and return wires given a list of edges.
* transformed/translated/rotated/scaled(), return a new shape with
some transformation.
* findPlane(), find the plane of a planar shape
* isCoplanar(), check if two shape are coplanar
When facemakers were introduced, Solid property of Revolve and Extrude
was made strict: it calls facemaker if Solid==true, and facemaker would
fail if shape being extruded/revolved is a face.
This is fixed by testing there are no faces in source shape prior to
calling facemaker.
Part::FaceMaker::ConstructFromType() could return null pointer if
abstract class type is supplied.
Here, it is fixed by checking for null pointer in facemaker itself,
rather than in every place ConstructFromType is being used.
* split Dir into Dir+Length; added second Length
* support for parametric linked direction: to arbitrary edge, and to
normal
* options: reverse, symmetric
* second taper angle
* changed offset join mode for tapered extrusion on OCCT7
