Pellipse resolustion

[ColinPearson]

**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!

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.

Can that be controled with TOOLS > OPTIONS > DISPLAY > Segments in a Polyline Curve?

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.

I am working with an old version of AutoCAD, so there are new buttons that I have never heard of. 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.

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]

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.

I may change OP to Opie. Big Andy Griffith fan back in the day.

[eldon]

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.
