The object is this scene is a Max NGon with a PExtrude operation.
I wish to fillet the face or edges but nothing happens, see movie:

Thanks for the Vid. Very nice.

I had the same problem in trying to do a 3dnpower logo. I used the max ngon spline and ran into all kinds of problems. I asked Gary what was up and he said the Max ngon spline is very inaccurate and that when you apply functions on top of it that it becomes unstable and errors will result like fillets failing :)

So just I just used power sketch in linear mode and snapped to the verts. worked like a gem. \\

We plan on adding default npower Shapes in the future to work around the issue.

Ok, the other Eric mentioned in one of my (lately) many posts about using Max objects,
maybe I am getting the message.
I recreated the shape with PSketch and it worked quite well.

Thanks guys!

I'm getting errors on native PN objects when filleting as well. I run into errors when filleting an object, ok this may happen, but then it will cause other selection sets to fail that were ok before. I have to have had created a duplicate object before starting or I will have to either go to a previous save or rebuild the object.
Very frustrating!

Can you send us the model where the filleting fails? I'm not sure that I understand the part about creating duplicate parts, but that sounds like an unnecessary hassle.

When filleting complex parts, fillet the large fillets first. Also, make sure that the fillet radius isn't bigger than any of the adjoining edges (we don't have a good way of handling edges that would essentially be consumed by a filleting operation on an adjoining edge).

If/when I run across it again, I'll send you the file, I am not able to reproduce it right now.
I do understand about the radius of the fillet not exceeding the size of the adjoining faces, but am sure that this is what the problem was on a number of occasions.
My tendency often was just to select all (faces or edges) and try to fillet them, then I would get an error in one of the smaller faces/edges.
After a failure of this type the object seemed somewhat corrupted from then on.
Now that kind I can reproduce, and that was why I was duplicating the object before doing the fillet operation since it was permanently "marked" with red squares at places where the filleting failed. At that point, the filleting wouldn't work as it should on the object any more.

I may have come across this problem in the past. Please if you find an object that does this save selected and send it to me asap. I would really like to hunt down this problem.

Don,

First I want to thank you again for your feedback. It is top rate. I would like to ask if in the future you could start a new thread for each of your problems. This will make it easier for others to find your thread.

Thanks a million.

Sure, Eric, I'll be sure to start new threads for each issue.
Think I was getting kind of self-conscious with all my entries on the forum.

You would not have asked any of these questions if you could have found the answer. Now others can find the answers.

Good point.

Eric,
I remembered the object that was giving me the trouble and decided to rebuild it to see if I could reproduce the problem.
As seen in the movie the filleting fails at every point except along the top and bottom curved edges and trying to do a second select edge set and filleting also fails.

The problem is the vertically extruded object. Your tangency on the vertices where the arc connects to the straight lines is not correct. Convert to EDitSkt, turn on Inference and line up the vertices. Reextrude and add to the boolean. Add a New Pwr_Fillet select the edges and fillet. Works perfect once you fix the extruded curve.

Edit: Easier workflow. Select Pwr_Extrude01 from the Boolean object, Extract an Inst of it. Select the extract object and go into the Pwr_Sketch vertex sub-object. Turn on Inference (set the value to 1.0). Select the vertices where the arc connects to teh straight lines. Make them Bezier. Snap the tangent handles so they line up with the vertice they are connected to. Go back to the Pwr_Fillet and reselect all the needed curves, DONE.

Ok, works for me!
Thanks!

I did the original sketch with grid snaps and Bezier sketch drawing.

Looks like there are quite a few getting started tutorials that have been added since I was there, think I'll go through them and the older ones too.
