I had faced a problem for a long time when I fillet some line&arc in skech, some time it came ellipitical fillet instead circle fillet. I have to redo several times to correct it. Any body have the same experience or any tip to solve the problem?
I have come a cross on the same problem, regarding you use circular fillet Pro/E creates elliptical. That happens because when you picking start and end of circular fillet, you pick to different distance of start and end point, then Pro/E thinks he is smart so he assume that you want to create elliptical fillet
.
The only thing you can do to prevent this is to pick approximately same length of start and end point.
I did the same way as you discribed but it was so frustrating that It automaticlly come a elliptical fillet when I think the length was already equal enough, so I had to delete it and do it agian several times.
How can we make Pro/E don't so smart at this point?
I don't know any other way unfortunately, maybe there is config option that exclude smart assuming by ProE, but I'm not aware of it. I avoid creating fillets in sketch as much as possible, and when I create one then I'm using method that I describe above.
Maybe if you would contact support they will repair that bug (but then I wouldn't be so optimistic because I reported huge bug that crash Pro/E, almost a year ago and they still didn't fix it
I am very new to pro-e and I have already found this to be very frustrating, I have found that using the "constraints tool" makes things a little easier, I think that you just have to be more careful when sketching. At the end of the day, pro-e does not let us get away with as many errors as what autocad did
On the version I am using, wildfire 2.0... when I get a sketch error it usually highlights where the errors are with a red circle, another frustrating this is that the red circles dissapear when you move the window that pops up... they need to fix that too !
IMHO fillets in sketch are (nearly) always a bad idea. Geometry consisting of lines is much more robust than a mixture of lines and arcs. Of course this attitude has its origin back in the old days when any changes in geometry resulted in fillets flipping like in the image below.
Both solutions are equally correct in terms of connections and tangency, only the left one isn't what you want.
When fillets in sketch are meant to be rounds in the model it is far better to construct them as rounds. You have better control, you can make sets that share their radius, you can suppress them as a feature to "lighten" the model when in a heavy assembly, etc.
Breaking up models in discrete steps with manageable sketches makes life easy for anyone who has to go in afterwards to change. Including yourself.
Adding rounds later in a model has the added bennifit of being able to supress them for down stream uses: simplified reps in assembly, FEA, etc. However, there are times when you have to include them in a section. I have never had a circular fillet turn into an eliptical fillet in 16 years of using Pro/E. I think the people having the problem are picking the wrong type of fillet from the menu.
I have never had this type of problem either... I did try and create a fillet when the elliptical icon is active and that is what it creates. Make sure your tool bar has the circular fillet icon active on the toolbar image I have shown in my previous post...
That happens because when you picking start and end of circular fillet, you pick to different distance of start and end point, then Pro/E thinks he is smart so he assume that you want to create elliptical fillet
??? That's not true, locations of picks for fillet are approximate points where circle is tangent with surrounding entities.
I never use elliptical fillet, but also I never experienced an elliptical appearing instead of circular (from Pro/E 2000 to WF2).
