Treehugger Posted May 27, 2019 Share Posted May 27, 2019 As the title suggests I am looking for help on how to merge overlapping circles to form an overlapping shape as per the attached. I created the attached in Adobe illustrator. How can I achieve the same result in AutoCAD. Thank you for any assistance you can provide.

lrm Posted May 27, 2019 Share Posted May 27, 2019 Convert the circles to regions then do a Boolean Union. Quote Link to comment Share on other sites More sharing options...

lrm Posted May 27, 2019 Share Posted May 27, 2019 Give the region command and then select all the circles. After converting the circles to regions give the union command and select all the regions. The resulting shape is a region. If you want it as a single polyline then explode the shape which will make it a bunch of arcs. YOu can then use pedit join (J) to join the arcs into a single polyline. 1 Quote Link to comment Share on other sites More sharing options...
Treehugger Posted May 27, 2019 Author Share Posted May 27, 2019 Excellent! Thank you very much for taking the time to set it out for me. Quote Link to comment Share on other sites More sharing options...
steven-g Posted May 27, 2019 Share Posted May 27, 2019 Another method would be to draw a rectangle larger than the circles (so they are inside the box) and then use the "boundary" command, make sure island detection is turned on and then pick a point inside the box, but outside the circles, and it will draw a polyline for you tracing the outer edge of all the inner circles. Then delete the bits you no longer need. 2 Quote Link to comment Share on other sites More sharing options...
Treehugger Posted May 28, 2019 Author Share Posted May 28, 2019 Thanks steven-g. That sounds like a quicker route. I am going to try that too. Cheers. Quote Link to comment Share on other sites More sharing options...
