Description

The FEM PostCreateFunctionBox function defines how a mesh is cut geometrically. It is used by Function cut filter and Region clip filter.

Usage

Create a sphere function

  1. There are several ways to create a function:
    • Press the Box button.
    • Select the Results → Filter functions → Box option from the menu.
  2. The Implicit function task panel is opened.
  3. Optionally set the values for the center and size of the section box.
  4. Press the OK button to finish.

Edit a sphere function

If the Box object in the tree view is hidden, select the Box object in the 3D view and press Space to make it visible, like in this example:

Move the box

  • Click and drag the big white cuboid to move the box along its normal vector.
  • Click and drag the white grid.

Rotate and tilt the box

  • Click and drag a line that connects the small cubes with the the big white cuboid to rotate and tilt the box around its origin.

Scale the box

  • Click and drag one of the 6 small cubes are handles to adjust the size to scale the box.

Notes

  • Existing functions can be used for different filters and even for different result pipelines. It is nevertheless recommended to use a separate set of functions for each pipeline to keep track of the elements in the tree view.
