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 box function

1. Press the Box button or 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 box 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 a face of the box. The box is defined by blue edges.

Rotate and tilt the box

• Click and drag one of the 3 lines that pass through the box to rotate and tilt the box around its origin.

Scale the box

• Click and drag one of the 8 small cubes at the box corners to scale the box.

Transform the box

• Click and drag one of the 6 small cubes around the center of the box to change the shape of 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.
