The Surface Trimming command is used for surface trimming.

Step-by-step instructions

1.Select the result of the operation by clicking the respective button in the Result group in the Main section of the Parameter Panel.

New surface (default option) — the result of trimming is saved in the model as a new surface. The original surface will remain, however it becomes hidden one.

Trimming the original surface — the selected surface is trimmed.

2.Select the surface to be trimmed. For this purpose, select the faces of solids and/or surfaces in the graphic area. The names of the faces are displayed in the Surface Faces field on the Parameter Panel.
If you want to trim all the faces of a solid or surface, select the solid or surface itself. In this case, the name of the selected solid or surface will appear in the Surface faces field. The notes on selecting a solid/surface as a clipping object are the same as for selecting a solid or surface as a secant object. Details...

3.Define the secant object. To do this, click in the Sectioning object field on the Parameters Panel and specify the object in the graphic area or in the Design Tree of the model. The name of the object will appear in the Sectioning object field.

Requirements to sectioning objects...

If you need to trim a surface by the isoparametric curve, you can plot this curve without exiting the trimming process. To do this, click Isoparametric Curve to the right of the Sectioning object field. The operation of creating an isoparametric curve on surface..

More details on using the isoparametric curve...

4.A part of surface on either side of the cutting border may be deleted. In the graphic area, the cut direction is indicated using an arrow pointing towards the deleted part of surface. To change the clipping direction, click Change Trimming Direction on the Parameters panel.

5.You can hide or keep visible the solid or surface used as a cutting object. The option Delete secant object serves this purpose.

Enabling this option means that after the surface is trimmed, the secant object will be hidden in the graphic area. You cannot enable its display in the graphic area. If the trim is deleted, the secant object will become visible again.

Disabling the option means that the secant object remains visible in the graphic area. After the completion of the operation, the secant object can be hidden manually. More about managing the visibility of objects...

The Delete secant object option appears in the Parameter Panel if a solid or surface is selected as the cutting object.

6.You can rename the trim operation in the Properties section.

7.If the operation results in a new surface, you can configure the parameters of its display using the Displaying group located in the Properties section. More about setting the color and optical properties of objects...

8.To complete the operation, click Create Object .

Depending on the selected result of the operation (see above), the following happens in the graphics area: either a new trimmed surface appears, or the original surface changes to reflect the trimming.

In the Feature Tree, a new element appears, which represents a surface created by trimming or a trimming operation.

If the operation results in several separate surfaces, then after completing the operation, the process of changing the set of surfaces is started. Select the surfaces that you want to keep. Details...

Each of the resulting surfaces is a separate object. You can independently change their colors, hide them or move them into layers. But they will be registered as created by one feature, i.e. they will all change in case you edit the plotting feature.

9.To complete the operation of the command, click Finish .

If you've selected a solid or its faces as trimmed object, then trimming may result in disrupting its integrity. More about solids with disrupted integrity...
