The blunt tangency command is used to eliminate small angles in the model caused by fillets. The operation 'blunts' the tangency, or small angle, by cutting out the surfaces adjacent to the specified vertex and replacing them with other surfaces that wash over and eliminate the small angle.

As shown in Figure 1, the depth parameter controls the depth of the surfaces that replace the tangency, while the angle parameter controls the resultant angle of the new tangency. Figure 2 demonstrates the behavior of the remove_material option which removes material instead of adding it.
