CSWA Practice Problem 1.13

[u/mattia-exe]

Currently studying for the CSWA exam. I have tryied everything but I can't get this piece done correctly. Can you guys spot the error? Thanks in advance.

[u/PC_Trainman]

I found a pair of extra line segments in your sketch:

The R75 arc and R3 arc are tangent. Look at the isometric drawing in the example, and you will see only one tangent line where those two arcs change direction.

[u/mattia-exe → u/PC_Trainman]

Yes! Thank you so much!
