[Solved]Projection of Wire on Mesh

[HakanSeven12]

I will try it

[HakanSeven12]

With this I got for most of the wires a satisfactory solution

Yes most of it works but some of wire dont extend to edge. They stay last triangle edge.

I can create projected wire like this by using Mesh.crossSections. But I can't finish projected wire at base wire last point.

Code:

Code: Select all

import MeshPart, Draft

GuideLinesGroup = FreeCAD.ActiveDocument.Test.Group
SectionGroup = FreeCAD.ActiveDocument.Group
CopyMesh=App.ActiveDocument.Surface.Mesh.copy()
Base = CopyMesh.Placement.Base
CopyMesh.Placement.move(Base.negative())

for Wire in GuideLinesGroup:
	CopyShape=Wire.Shape.copy()
	CopyShape.Placement.move(Base.negative())

	Vec = CopyShape.Edge1.Vertexes[0].Point - CopyShape.Edge1.Vertexes[1].Point
	Vec.x, Vec.y = -(Vec.y), Vec.x

	Section = CopyMesh.crossSections([(CopyShape.Edge1.Vertexes[0].Point,Vec)],0.000001)
	print(Section)

	for i in Section[0]:
		Pwire = Draft.makeWire(i)
		Pwire.Placement.move(Base)
		SectionGroup.addObject(Pwire)

FreeCAD.ActiveDocument.recompute()

With git commit 115ff0191 everything works now.

With git commit 115ff0191 everything works now.

Does same macro work or I need to change something?

[wmayer]

Same macro.

[HakanSeven12]

Okey I will try when next build available

[HakanSeven12]

Same macro.
