View Full Version : How to break a circle or arc?

I was trying to make a sign with an oval shaped object that overlaps a rectangular object. The are regions on the interior of these objects which are carved out. I then wanted the whole piece cut out. I found that you cannot break a (or add a vertex to) circle or oval. I wound up tracing the oval with a number of arcs (which was rather slow). Is there a better way to do this?

I attached the project so you can see what I mean.

Jeff,

Very nice project! Your idea brings to mind many possibilities.

It certainly would be nice to be able to combine objects into one. I played around with your concept and was able to create the recessed areas a little differently by working with the clip carving (inclusive/exclusive). Still, the problem is cutting the project out as you have it.

SpiffyDog,

Very cool! your method certainly made the project easier. Still have to trace the outside, dang it. Perhaps CW will fix this in the future. Maybe, I'll add this as a feature request.

I found that if you want to manipulate a circle you really just want to convert a rectangle to a circle. To get a perfect circle use a square (though not as flexible, but better looking).

Draw the rectangle and convert each red vertex with the make spline tool from the Utility toolbar.

The one I originally posted looked the way I wanted it to. It was just a pain to have to trace around the ovals since you cant break an oval or circle. I was fishing for better methods.
