double/triple faces?

Hi CGMike,
this is a problem I've never experienced myself as far as I can remember.
I don't really understand what were you first modeling steps with the geometry displayed on the pictures ... a polyline (with inserted vertices) extruded on -Z ?
Just a thought, have you tried extruding edges by only using the menu (vertex/extrude edges) and not the CTRL+E keys on your keyboard (just in case you could be pushing CTRL+E more than one time sometimes) ?

I started with a single, un-subdivided plane. I then started by selecting two vertices to effectively select an "edge" and press Ctrl+E to extrude it.

I'm not pressing more than once. While doing testing of it I made sure I was not pressing more than once. So that's not it. Like I said, it happens randomly, I can go for 10 minutes without a single incident.. sometimes it happens 2 or 3 times within a few minutes... it's very random.

Like luuckyy, I haven't seen this problem during my own modeling. I think it would still be good to try the menu command as luuckyy suggests --- if it can be reproduced from the menu without pressing the hotkey, that would tell us whether it was a keyboard issue or not. Not just a question of whether you're hitting the Ctrl+E more than once, but perhaps the key is "sticking" and getting read more than once.

Using the menu can be tedious, of course, but another option is to add Extrude Edges to the toolbar using the toolbar editor ( http://www.ac3d.org/forum/showthread.php?t=3688 ). Again, just to see whether it is keyboard related.

Another option if you do not want to install the toolbar editor is to use the attached tcl file. Drop this into the "scripts" folder under your AC3D installation folder and restart AC3D, and you will get a new "Extrude Edges..." menu item under the Tools menu. Issuing this will bring up a stay-on-top window with an "Extrude edges" button so you don't have to use the menu every time. Simply delete the file when you don't want the command present any more.

Since keyboards can have problem keys that temporarily "stick" for a second or two after being released, this may be the cause of the problem you're seeing. Being able to eliminate/confirm whether this is an issue may lead toward solving the problem.

Good luck

Hmm.. I'll give that a try, though it happens to me whether I'm working on my home keyboard or at work on my work keyboard.. the likelihood of the same exact key sticking in two different places seems a bit remote to me. If I have to press a button or use a menu command every time, it really defeats the purpose of having a shortcut key in the first place.

Can I reassign the shortcut key to something different?

It does seem very unlikely. AC3D must be getting the direction to perform the extrusion twice from somewhere, however.

I don't believe it's possible to have the edge extrusion happen twice without two extrusion commands being sent to AC3D (via keyboard/menu/button), but only Andy/Inivis could verify this. As before, however, if you can repeat it via button/menu rather than keyboard, that would certainly give them something to look at.

I find I *can* reproduce this by holding down the "E" key just a tad longer than normal (my keyboard repeat rate is set to the shortest delay possible). If I turn down the key repeat rate to Long, it ceases to happen, of course.

Good luck
