Introduction
Introducere
Această comandă creează o formă dintr-un mesh object . Obiectele din rețea au capacități de editare limitate în FreeCAD, transformându-le în forme, permit utilizarea lor cu multe alte instrumente în FreeCAD (vezi și Notes).
The inverse operation is Mesh FromPartShape from the
Mesh Workbench.
Usage
Utilizare
Limitări
There will be no analyzing or validating of the mesh object.
Analyzing and repairing of the mesh (if needed) should be done manually before conversion.
Appropriate tools are available in the Mesh Workbench.
After creation of a Shape, it may be useful to use Convert to solid (necessary for boolean operations) and Refine shape.

Scripting
Creating a Shape from a Mesh can be done by using the makeShapeFromMesh
method from a Part TopoShape; you need to specify the source mesh and tolerance, and assign the result to a new Part Feature object.
Notice that the mesh must be recalculated before it is converted to a Shape, otherwise there won't be topology information, and the conversion won't be successful.
import FreeCAD as App
import Part
doc = App.newDocument()
mesh = doc.addObject("Mesh::Cube", "Mesh")
mesh.recompute()
solid = doc.addObject("Part::Feature", "Shape")
shape = Part.Shape()
shape.makeShapeFromMesh(mesh.Mesh.Topology, 0.1)
solid.Shape = shape
solid.Placement.Base = App.Vector(15, 0, 0)
solid.purgeTouched()
doc.recompute()
