How would you calculate the curve length so the holes are 30mm apart?

There needs to be 9 holes at 30mm apart

Currently the part holes vary in distance

Thanks

What's the other conditions???!!! im not a wizard, i can guess what you have in your mind!!!!!! give me details!!!

You need the arc at 15mm from the interior slot arc?
The first hole starts where?

i dont know what you want in detail!!!

Ok... I Get it

If you want 9 "spaces" x 30 equal 270..... you must have.... 10 holes (not 9)!!!!

Now the question is... do you want the arc concentric at 15mm? or you have the side branches with 65mm? (you cant have both)

Here you have the two versions

Conditions:

CASE1

Arcs concentric

Branch with 65

arc 140

offset 12."something"

Conditions:

CASE2

Arcs concentric

Branch with 60, "something"

arc 149, "something

offset 15
