Applies a radius constraint to cylindrical surfaces or circular edges.

## Accessing the Command

command bar: **dmradius3d**

menu bar: **Parametric | 3D Constraints | Radius**

toolbar: **3D Constraints | Radius**

ribbon:

**Solid | 3D Constraints | Radius****Surface | 3D Constraints | Radius****Assembley****| 3D Constraints | Radius**

Quad cursor menu: **Constraints |**** Radius**

: **dmRadius3d**

Select a face or circular edge: *(Select a cylindrical surface or a circular edge) *

Enter radius value <current value>: *(Either press Enter to accept the current value, or type a new value.) *

Press the TAB key to select obscured geometry.

In case the surface of an elliptical cylinder is selected, the surface is converted to a circular cylinder.
