If you mean how to create a clipping attachment with perfectly straight edges, we don't currently provide tools to do that. You could export to JSON, adjust the values of the clipping attachment vertices, then use Import Data to bring it back into Spine. Some users do this to create a perfectly square 100x100 clipping attachment, then they translate or scale the vertices to get the actual size they want.
