It’s very important that the indicated step in the right of the attached image is removed for the correct piece working. I’ve inserted a R0.5 fillet in the new REV04 3D model. Also a chamfer would be ok, but the step is not allowed.The other modifications are indicated in red in the attached image “Image2.jpg”. Please provide also costs and timings estimation for the modification at Devis Cusin, who is reading us in copy. I will remain at your disposal for any technical clarification needed.Best regards
