Failed Circular Pattern: Unique Modeling Issue

Jesse Brown Aug 26, 2015 2:39 PM

I am having issues completing this circular pattern. I have used solidworks for years and have never seen this error message. Things I have tried to resolve the issue: 1. Draw a centerline 2.turn on temporary axes 3.new reference geometry axis 4. Using the surface 5. turn off temporary axes. I do realize that I should be able to sketch this cut and do multiple revolves around my part (it has some complex surface curvature that needs attention), however this will cause alot more work, and with solidworks I have always found usually satisfying approaches to models. I just am unsure about this one. Someone please help me figure out my problem!? thanks again.

could you post the part to look at.

  Yes do you mean the .sldprt/model or a picture? Thanks for your attention to this!

        I have had a look at the file. There are a few unconstrained sketches in the part but I would need to take a longer look and see why it is falling over. As a quick workaround I was able to use the axis you had created to create a circular pattern WITHIN the Cut-revolve sketch and then I update the cut-revolve to get the cuts you require - see attached.

        Thank you, I figured this was the fix to my problem, I just don't understand why it had an error before. I do understand the unconstrained sketches, however I never saw any geometry that conflicted with others. I did take a look but I could have missed something. If you do look more into this, I would love to know what was messing it up because I have spent hours on it so I would never have to see the warning again... Thank you for the help again! and for now sketches are my way to go for weird patterns!

        Hi Jesse,
        
        Ok I was able to get it to work. I actually just re-ordered the cut-revolve, surface and axis before the previous cut-revolve and it worked. Something in the order was causing it to fall over. Anyway I have attached so you can review.

        Thanks for help on this, you saved my day and the rest of my week on time! After your modification, I tried to mirror those features to the other side, and got the exact same error as I had in the original picture. To fix my problem, I cut the body in half and then mirrored the good side as a body and merged. Easy enough to do that way. I wonder what the "technical" reason is, as this error is one I havent seen. I guess it could also be partial to 2015. Either way thanks again for the help?
