Get the diameter of a CylindricalFace selection

[sandeepdutta]

Hello All,

I am selecting a CylindricalFace using

si = inputs.addSelectionInput('wheelDia', 'Select Wheel Outer face', 'Select wheel diameter surface')

si.setSelectionLimits(1,1)

si.addSelectionFilter('CylindricalFaces')

How do I obtain the "Diameter" of the selected  CylindricalFace.

What you'll get back, in this case, is a BRepFace object. A BRepFace object represents any face in a model, regardless of its shape. But because you've set the filter to "CylindricalFaces" it will only allow the selection of BRepFaces object whose underlying geometry is a cylinder.

The BRepFace object supports the geometry property, which will return one of many types of objects depending on what type of geometry is associated with the BRepFace. In your case, it will always return a Cylinder object. The Cylinder object supports many methods and properties to get information about the cylinder, including the radius property which will return the radius in centimeters.

That worked out. Thank you.
