The company that I work for specializes in plastics, the production of instrument panels. I have come across similar perpendicularity call outs on various occasions. I am curious, could the intent here also be a reference to the direction that the part is to be released off the mold? I thank you in advance. I appreciate all the great information that is presented in this forum.
