Acknowledged loft/shell issue Inv 2010

Hello all, thought I would pass on an acknowledged bug in a lofted/shelled solid in Inventor 2010. Bear in mind that I have been doing this workflow since Inventor 5.3  or so. Imagine my surprise when I installed 2010 and found out I had to workaround this issue as best I could. Imagine my larger surprise after talking with my reseller (good people) that Autodesk acknowledged the bug, but they have not issued a fix for it. This bug is not present in 2008 (previous release used) or 2011 (have not upgraded yet because of workload and a couple of other issues). This was acknowledged as a bug sometime in January 2010. Open the attached loft1.ipt and pull down the EOP. edit sketch1 of Loft1. change the 3 to 3.5 and the 5 to 5.5 and see what happens to the corners. I am told that Inv 2011 does not have this bug, only Inv 2010. I will stop now before I really get going on a rant

hmm...that's weird.

 

Work around was fairly simple, but it the way you've done it seems the most logical to achieve your end result and that way is obviously not a proponent of change.

Hi! Indeed, I see no reason why this case should fail. I have forwarded it to development for review. Regarding how to make it work for now, there are two workarounds I can think of.

 

#1, Edit the loft->check Merge Tangent Faces.

#2, Instead of creating shell, create an offset surface and split or sculpt the body to hollow it.

 

Thanks!

workarounds

I agree, there are multiple ways to work around this issue, which is what I have been doing for the last ummmmm 7 months. If was the finished product, that would not be a problem, however this is the beginning of the solid, and other features are added, etc. Workarounds are just that, more work to get around the issue.

 

Thanks for your response
