zera Posted December 16, 2009 Share Posted December 16, 2009 I'm drawing up a part, and the top profile is an ellipse. The other geometry is lines and circular arcs. The arcs and lines will join together, but the ellipse won't I've checked the points to ensure that they are connected, and they all are. Even when I increase the fuzz distance. Using pedit btw Thanks Quote Link to comment Share on other sites More sharing options...
eldon Posted December 16, 2009 Share Posted December 16, 2009 An ellipse is a separate AutoCAD object type so will not join up using pedit. However, a quick way to convert an ellipse is to offset it and the offset line becomes a polyline. Then erase the original ellipse and offset the offset back by the original amount, and you have a polyline where there was an ellipse. The picture shows the offset, and I have shown the grips so that you can see the difference between the ellipse and the polyline Quote Link to comment Share on other sites More sharing options...
CarlB Posted December 16, 2009 Share Posted December 16, 2009 One more step- the ellipse offset is actually a SPLINE, so use FLATTEN to convert to a polyline. Quote Link to comment Share on other sites More sharing options...
eldon Posted December 16, 2009 Share Posted December 16, 2009 Thank you for the final step CarlB. I expect you have a Lisp to do it in one go. Quote Link to comment Share on other sites More sharing options...
SuperCAD Posted December 16, 2009 Share Posted December 16, 2009 is PELLIPSE an option for you? Quote Link to comment Share on other sites More sharing options...
CarlB Posted December 16, 2009 Share Posted December 16, 2009 I expect you have a Lisp to do it in one go. No, but fuccaro does http://www.cadtutor.net/forum/showthread.php?t=1639 Quote Link to comment Share on other sites More sharing options...
fuccaro Posted December 17, 2009 Share Posted December 17, 2009 Thank you Carl! Zera, if you decide to use that Lisp, read all the thread and use the latest routine posted. The first ones have small bugs. Quote Link to comment Share on other sites More sharing options...
zera Posted December 17, 2009 Author Share Posted December 17, 2009 Thanks guys, I got to playing around with it some, and converted it to a region instead of using pedit. I've been having to calculate the area of a part to estimate material costs. I was trying to convert to polyline for tool and die. I appreciate it guys.
