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 and starting point for the cone/frustum.  The standard point input options are available.  This point will remain fixed as the Align Plane option (see below) is applied.

• 1st Radius, Length, 2nd Radius - The 1st radius is applied about the center point (see above) and lies on the default plane or the optional Align Plane (see below).  You can drag or enter the exact length which is normal to the default plane.
  
  You can let the 2nd radius default to zero for a cone or specify it to create a frustum.  The 2nd radius is applied about the length point and is parallel to the default plane.  Refer to the figure.

 

 

 

Align Plane

Use this option to align the cone/frustum with a datum plane or planar face.  The center (see figure) will remain fixed and the 1st radius of the cone/frustum will be aligned.
