ColinPearson Posted October 14, 2011 Share Posted October 14, 2011 (edited) **I can't type today - title shouldread Pellipse Resolution **LOL, still can't type... I know this should be easy, but can't figure out yet. How do I change the resolution of a pellipse so that I can get many nodes for import into FEA? Thanks all, and keep in mind that the weekend is CLOSE! Edited October 14, 2011 by ColinPearson Quote Link to comment Share on other sites More sharing options...
eldon Posted October 14, 2011 Share Posted October 14, 2011 I am making this up as I go along, but as far as I know, Pellipse only enables a Polyline to be drawn instead of an ellipse. There is no facility to increase nodes. However, I had a go, and by successively using Pedit with the Fit Option, then exploding the polyline, and rejoining with Pedit, the number of nodes does increase.

Dana W Posted October 14, 2011 Share Posted October 14, 2011 Can that be controled with TOOLS > OPTIONS > DISPLAY > Segments in a Polyline Curve? Quote Link to comment Share on other sites More sharing options...

Dana W Posted October 14, 2011 Share Posted October 14, 2011 Can you post a screen shot so we can see? I don't have a dwg at hand at the moment and I have not tried it. Lemmee try it out and I'll let you know. Heck, I's hopin' you'd know it off the top o' your head. Quote Link to comment Share on other sites More sharing options...

Perhaps you could guide the OP to these new buttons and give a before and after screen shot to demonstrate the effect of more segments, shown by more grip nodes.

Now that I am on my computer with AutoCAD available..... The answer to my own question in post #3 is Nope, nothing to do with it, won't change anything except how the elipse looks when you need a regen. The answer for the OP's question is, change the value of the system variable PELLIPSE to 1. First, F1 pellipse then read. Pellipse = 0 - Creates a true ellipse object and has grips only at center and each axis end. Pellipse = 1 - Creates a series of joined polyline arcs with a grip at each end and midpoint of each arc.

eldon Posted October 15, 2011 Share Posted October 15, 2011 I suspect that the OP had already found out that by changing Pellipse to 1, the ellipse command was drawing a polyline instead of a true Ellipse. But the OP was wanting more nodes to the polyline - hence my suggestion which would seem to work, unless someone knows better. The process seems to be a reverse Weed.

Dana W Posted October 15, 2011 Share Posted October 15, 2011 I didn't assume OP new whether pellipse was a system variable or a command, or that OP had changed the value off the default. Your solution is a workable one though. I hope OP's comment about the weekend doesn't mean his deadline is already passed. Can you explain what Reverse Weed means? I have this mental image of somebody blowing a bong like a tuba. (Personal experience not used for reference) I sure am glad I grew up in the sixties and got it over with.:roll: I may change OP to Opie. Big Andy Griffith fan back in the day.

eldon Posted October 15, 2011 Share Posted October 15, 2011 When you want to reduce the number of nodes in a polyline, there is a Lisp called "Weed", which decreases the number of nodes. The OP wants to increase the number of nodes - hence "reverse weeding". I hope you don't take this out of context I suspect that the OP is having a good weekend, and might have a good chuckle on the next day of work.

ColinPearson Posted October 17, 2011 Author Share Posted October 17, 2011 @Eldon - laughing my a** off this morning indeed. I checked out to take my kiddo camping all weekend and found this thread when I showed up at work. I'm off to the other screen right now to check your Pedit suggestion; I think that will Fit my needs. Sorry. Terrible, terrible pun, but it couldn't be avoided. @ Dana - I also had to know what a Reverse Weed was... that one threw me for a loop. LOL And nope, no deadlines have passed yet Thanks folks for the replies, and especially for the image of someone blowing a bong like a tuba. All Mondays should start with something like this.
