How do I... divide a continuous loop region for equidistant bolt holes.

[steamwise]

I want to create a series of holes to bolt a cylinder cover to a cylinder block. I have created a region that consists of two half circles (different radii) and two tangential lines. The holes have to be equidistant. I have tried using divide but it doesn't like my region. Thanks.

P.S thanks to StykFace for answering my last post, cheers.

You have to use a line or a polyline for DIVIDE or MEASURE. So copy the region somewhere, explode, join to create single polyline, "divide" that object, copy "bolt holes" back to region.

Thanks CarlB, thats sorted it, cheers.
