Description
The Mesh TrimByPlane command trims faces and parts of faces on one side of a plane from a mesh object.
Usage
- Select a single mesh object and a single Part plane. The (extended) plane should intersect the mesh object.
- There are several ways to invoke the command:
- Press the
Trim mesh with a plane button.
- Select the Meshes → Cutting →
Trim mesh with a plane option from the menu.
- Press the
- The Trim by plane dialog box opens.
- Select the side you want to keep by pressing one of the buttons:
- Below
- Above
- Split: removes the faces and parts of faces above the plane, and creates a new mesh object containing them.
Scripting
See also: FreeCAD Scripting Basics.
To trim a mesh with a plane use its trimByPlane
method.
import FreeCAD as App
import Mesh
# Create a non-parametric box-shaped mesh:
msh = App.ActiveDocument.addObject("Mesh::Feature", "Mesh")
msh.Mesh = Mesh.createBox(30, 40, 50)
msh.ViewObject.DisplayMode = "Flat Lines"
# Define a plane by a base point and a normal vector:
pnt = App.Vector(25, 0, 0)
nor = App.Vector(0, 0, 1)
# We need to work on a copy of the msh.Mesh object:
new_msh = msh.Mesh.copy()
# Trim that copy:
new_msh.trimByPlane(pnt, nor)
# Update msh.Mesh:
msh.Mesh = new_msh
