FreeCAD: Divide a face into multiple faces

FreeCAD 0.19

A face can be divide into multiple faces with FreeCAD. For example, with this function, you can set load condition on a part of the single face in physical simulation on FEM workbench.

Steps

  1. Select [View]-[Workbench]-[Sketcher] menu to switch workbench to sketcher workbenchsketcher workbench.

  2. On 3D view, click a face that you want to divide. Make sketch planeSketcher_NewSketch on selected face and draw the face region as sketch.

  3. Select [View]-[Workbench]-[Part] menu to switch workbench to part workbenchWorkbench_Part.

  4. In model tree, first select the shape that has the face to be divided (In the example, cuboid), and then select the sketch defining face region (In the example, sketch defining a circle). You can select multiple item by clicking them with Ctrl key.

    Execute "Slice to compound"Part_Slice to create a face region on the plane from the sketch.

The face region like this can be used in simulation in FEM workbenchWorkbench_FEM. Forexample, you can set load condition at a part of single plane in condition settings.
