Clip Model

The "Clip Model" function enables you to cut off parts of the model.

When you have activated the function, the model is encased within a 3D box whose sides can be adjusted by the arrow tools. The functions correspond to those used to adjust the wind tunnel (see Chapter Wind Tunnel). The "Box coordinates" displayed in the panel enable you to control the size in detail.

Click the Button "Apply Clipping" button to crop all parts of the model that are not contained in the box. To cut off the parts within the box, however, activate the "Invert" option before clipping.

Tip

Watch this video to see how a model can be clipped.

Tip

Note that the "Clip Model" function deletes parts of the model. If you want to create visibilities of specific parts, for example to assign zones, use one of the "Cut" options in the toolbar list.

Important

When a model is clipped, the triangular meshes are trimmed. This approach may lead to imperfect results for cases when closed surfaces are not fully recognized. The tool (which is part of the VTK library) is not 100% perfect, but still very useful so that its advantages outweigh the shortcomings.

Split Model

This feature allows intelligent division of the model into multiple parts and is very useful, for example, for separating a part of the model intended for detailed calculation with increased accuracy and mesh density

To apply the Split Model function, select the "Clip Model" function from the "Edit Bar" and check the check boxes, see Split Model.

Then click the Button "Apply Clipping" button to split the model into two parts and it is possible, for example, to increase the "Level of Detail" of the model, see the figure below.
