Fillet Feature API Sample

Description

Demonstrates creating fillets using the various types of fillets. Create a new design and add a box that is at least 2 cm on each side. The script creates a constant radius, variable radius and chord length fillets. After creating each one, it deletes it and then creates the next. To see any of the fillets that were deleted, undo to get the fillet back.
