Select the feature type icon. For the Add, Remove and Intersect types, the topology of the active part will be altered by the feature.  The Base option is automatically selected if the active part has no shape geometry.

 

 

	Base - A separate base feature will be created.  Base features are used to define the initial basic shape of a part.
	Add - A shape will be created and then added to the active part.
	Remove - A shape will be created and removed from the active part.
	Intersect - A shape will be created and then intersected with the active part.

 

 

• Center - Select the center point for the cylinder.  The standard point input options are available.  This point will remain fixed as the Align Plane option (see below) is applied.

• Radius, Length - You can drag to select points on the diameter and length of the cylinder or specify the exact radius and length.

 

 

 

Align Plane

Use this option to align the cylinder with a datum plane or planar face.  The center (see figure) will remain fixed and the radius of the cylinder will be aligned.
