I didn't understand the dimensions of the rounded part and what is 45 arrow. if someone can explain these dimensions and how to extrude them
I think that the R50 is the radius of the arc used and the 45 is the locating dimension of the center point of the arc from the top of the 25mm thick surface. The intersection point of the arc with the 40mm thick surface is located 60mm from the right end of the part. If you need further help post a copy of your part and I can modify it for you.
Thank you very much, it worked.
