• Ref. Geometry >> Create >> Cone >> Fit Region command adds a reference cone by fitting selected faces/vertices to the surface of the cone.

Execute Ref. Geometry >> Create >> Cone >> Fit Region command as follows:

1. Select vertices or faces on the region you would like to fit the cone to. ( See Select >> Entities >> Vertex / Face )

2. Select Ref. Geometry >> Create >> Cone >> Fit Region from the menu or click the corresponding icon from the Reference toolbar.

3. The following dialog may appear.

Use Add Fitted Geometry option to best-fit a cone to the selected faces/vertices. Use Add Max. Bound Geometry option to create a maximum cone including all the selected faces/vertices. Use Add Min. Bound Geometry option to create a minimum cone which does not include all the selected faces/vertices. Use Remove Outlier option to fit a cone to the selected faces/vertices while excepting entities in the region out of standard deviation. Use Ref. Vector sets a given ref. vector as a initial guess for the vector of a primitive to be generated. Fix Axis sets the given ref. vector to a vector of a primitive to be generated.

4.Click Preview button and then click the Create button to create a cone.
