# SolidClip

VTKExamples/CSharp/Meshes/SolidClip

### Description

This example clips a mesh and applies a backface property to that mesh that appears to have a solid interior.

A tutorial on how to setup a Windows Forms Application utilizing ActiViz.NET can be found here: Setup a Windows Forms Application to use ActiViz.NET
Note: As long as ActiViz.NET is not build with VTK version 6.0 or higher you must define the preprocessor directive VTK_MAJOR_VERSION_5.
