Ref. Geometry  >> Create >> Torus > Fit Region

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

 Step   

Execute Ref. Geometry >> Create >> Torus > Fit Region as follows:

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

2. Select Ref. Geometry >> Create >> Torus > 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 torus to the selected faces/vertices. Use Add Max. Bound Geometry option to create a maximum torus including all the selected faces/vertices. Use Add Min. Bound Geometry option to create a minimum torus which does not include all the selected faces/vertices. Use Remove Outlier option to fit a torus 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 torus.
