Axis pattern not working correctly.

[Nameistaken]

I have little experiencie with proE but I have experience in solidedge, NX and solidworks. so the proE logics sometimes escape my mind.

What i want to do:

Place 4 "L" brackets in the external face of the round part.​

What i did:

I created a round feature of a sketch to create the first bracket. axis on the center of the round part.
After that i tried to create an Axis pattern to place the remaining 3 brackets​

Results:

Depending on the method prefered i obtained no result, failed geometry and also offset brackets in the vertical axis.​

Im using ProE wildfire 5.
see attached files with various combinations resulting in failure.

Just constrain the bottom leg of your first sketch to the bottom surface.

Hi dgallup,

http://www.eng-tips.com/viewthread.cfm?qid=377968

in one of the files the sketch is not dimensioned, but in the other files sketches are fully constrained.

is there any reason for the offset on the features that did worked?

 

[dgallup]

Pro/E is pretty fussy about fully defining/constraining things. I don't know why they are moving around but I never use axis patterns. As an old school Pro/E user, I will always create a sketching plane through the axis that has an angle dimension then use a dimension pattern. That used to be the only way you could do it so I still do it that way. These newfangled types of patterns have some drawbacks. For one thing, if you do an axis pattern of holes, you will not be able to show a bolt circle axis in a drawing.

Yeah, i think i read that old school method for circular patterns somewhere else. I should do it that way. I just had some hope this issue was not there anymore :S

Thanks a lot

Unless there's a specific reason, don't make your sketches 'separate' from the feature that uses them. That's what seems to be causing your pattern problem (notice that the pattern elements are spaced down one sketch length).

To fix it, try this:
-delete the pattern (only the pattern) so that 'Revolve 2' is no longer being patterned.
-in the Model Tree, right click on 'Revolve 2' and select 'Edit Definition'.
-from the Ribbon, select 'Placement', which brings up a menu showing the 'Sketch 6' is the source for the sketch.
-click on 'Unlink', which essentially copies 'Sketch 6' into the revolve feature and breaks the link between them.
-re-create your pattern. When I did this, it was fine.

Thanks for the reply Gilmiril,

I did what you described, i keep having the same offset issue. (only in the files i attached here).

i did "save as" in another file and recreated those features again(before sketch 6) and everything worked fine, even without unlinking the sketch.
Also "copy>paste special>translate" also worked fine.
