About the 3D Contact User Interface
The 3D Contact tab consists of tabs, commands, and shortcut menus. A 3D contact is represented by

• References—Displays the selected contact references, and the vertex radius if one contact reference is a vertex. The default vertex radius is 2.5% of the size of the part's bounding box.
• Contact—Displays the Side 1 Contact Properties and the Side 2 Contact Properties. Select an option from the list.
◦ Select material—Click More to select a material to use.
◦ Use values—Type values for Poisson's ratio, Young's modulus, and Damping.
