It's Starting To Come Together Quickly But I'm Not Getting One Thing...

I have an old blueprint I working from. I need to create a trim from the geometry - I have numbers. Let me simplify this a bit so the issue should be clear. I'll describe things geometrically, not necessary as they appear on the blueprint or what be done in Evolve.

 

There are two non-overlapping circles whose centers are on a line. Say they have a radius of 8. Now take both circles and create a concentric circle of radius 12. Draw a line that connects the center of the circles. Draw a line perpendicular to the line connecting the center of each circle such that it goes through the center of each circle and intersects the outer circle in two places.

 

When the two perpendicular lines intersect the outer circles I need to place a rectangle such that I can connect the larger circles and use split curves to create a racetrack looking shape that can be used for a trim.

 

It's easy - thanks Darren! - to do this arbitrarily with two circles and a rectangle. Doing this with the concentric circles and connecting with a rectangle that comes last has escaped me. I've tried different approaches - varied geometrical and tool usage -and somehow the racetrack shape is not 'continuous' and so cannot be used for a trim.

 

Another have any ideas? There has to be a tool...

 

Thanks!

    Nevermind! I figured it out. I had to be very careful in placing my end points using the Bi-Tangent Segment (line) tool.
