Use your convex or concave options to do this.

Yes i know but i need to figure the start and end point, im new to programming

Let's start where you left off.

Concave Start X=18.5 Z=? Finis X=18.0 Z=27(34-7) Rad=20
Center X=58(20*2+18) Z=27 Intersect = up & right
Concave Start X=18. Z=27 Finis X=18.5 Z=? Rad=20
Center X=58(20*2+18) Z=27 Intersect = down & left

Hit Calculate It should give you the endpoint. I program in quadrant since the dimension is given, I found it easier. But you can program in one line.

Check Shape see they calculate it right.
Hope it will help
