Which dimensions are to be used from all these dimensions to draw this part in red ? and what does the different lines appearing means ( in orange )
I can't understand how to calculate right dimensions from all these dimensions. this is the link of the model that i want to practice. https://grabcad.com/library/desktop-fan-2/files/Creo%20Fan/blade.prt.13#
R23.9 + R29.21. THEN 2 FILLETS. BUT IT IS ACTUALLY NOT AS EASY AS ALL THIS. THE 2 RADII SHOULD ACTUALLY BE TO THE INTERSECTION OF THE FRONT FACE AND THE CONICAL FACES TAKING THE DRAFT ANGLE INTO ACOUNT FOR THE PLASTIC MOULD...
I'D SAY R24mm AND R29mm WITH 2 FILLETS OF R2.5mm
