So I thought this would be great since we do alot of this type of cut through cylindrical sheet metal parts...
It works great on flat pieces, but on an angled "rolled" part, it really messes up. Am I missing something?
Move the end of part up past "Cut1" and the cut appears, but also, it takes material off the back of the part!
HI TO ALL TIN BASHERS
I SPEND 90% ON INVENTOR TIME USING SHEET METAL, WHICH IS A PLEASURE TO USE MOST OF THE TIME
I LIKE MANY OF YOU HAVE LONGED FOR THE CUT NORMAL FUCTION, SO WHEN IN 2015 IT WAS ADD I WAS DELIGHTED
BUT DISSAPOINTED WITH IT'S LIMITATIONS. IT CANT HANDLE CUT TO CONICS OR CYLINDERS IF THE CUT PASSES THROUGH EDGES
AND CUTS TO BENDS THAT CHANGE DIRECTION SO FOR THE MOST PART ITS BACK TO UNFOLD CUT AND REFOLD
WHICH WORKS MOST OF THE TIME. BRAVO TO AUTODESK FOR STARTING THE PROCESS HOPE THEY KEEP IMPROVING
THE FUCTION UNTIL WE HAVE A MORE RELIABLE COMMAND

Hi Chris,
We've internally fixed both the issues that you reported at the beginning of this thread but we still have some validation to do. Nevertheless, keep an eye out for any Updates and Service Packs and thanks again for contributing to Inventor improvements 🙂
Feel free to get in touch for anything else,
Indy
And thank you for the encouragement and feedback, Phil!
Best wishes,
Indy
Hi! This particular issue has been resolved on the Update1 to R2015. Please download the update and try it out. After the update is installed, simply open the sheet metal part and do Rebuild All.
Thanks!
Hi! I think indeed, the issue is not completely resolved by Update1 yet. But, for the part you attached to this thread at the beginning, do you see the correct result?
The issue here is that Inventor fails to pick the persistent planar reference before and after cutting normal in this case. For contour roll profile on XY plane, the problem seems to go away on Update1. But, if the profile plane is not on XY, the bad behavior is still there. I will work with development and get to the bottom of it.
Many thanks!
Hi to all interested in the cut normal and pattern on cone developments
I have a solution that seems to work in most cases if you may be useful
to try. You may be able to follow the working from the ipt if not
i will run through the method and it also folds and unfolds ok

HI
With oblique cones you have to be careful where you place the opening
it does not like cutting through joins - the cut normal option still need working
on to make it more robust
please see one work around you may be able to use
cheers

Hi everyone,
I tried all the parts on Update1, and found the cut normal issue on the first part attached by Chris got fixed on Update1, but it still takes material off the back when circular pattern the cut normal. The cut normal issue still exists on the second part posted by Chris even on Update1(recreation or rebuild). The SA-RDC5X005.ipt attached by Smccoywm failed in one direction but succeeded in the other direction. I’m afraid it’s a limitation since it’ll pass through edges. Anyway, I’ll confirm this with our developers and product designer.
I’ll summarize all the reproducible issues (on Update1) and let our developers investigate them, and will keep you informed when getting addressed.
Sorry for any inconveniences it brings.
Thanks,
Webber
Hi Webber,
Now on update 2 for Inventor 2015 and still no fixes for sheet metal cut normal on the conics
and the inadility to pattern cuts, and the fold and unfold still not working on conic
wondered if any progress is being made or is this not a priority bug.
Cheers

Some cut normal issues will be fixed on Dyson SP1 instead of Update2. Please try it then.
Thanks,
Webber
I've got the same problem and other problems with a lofted sheet metal (circular both ends) part when trying to cut normal.
The part that is trying to be created is a cone for the top of a vertical round tank that has vertical nozzles in the top, we get this piece laser cut in flat pattern and are trying to add the holes to where the nozzles are required.
Problems:
-When cutting the part with a rip in it, it opens the rip up further or makes a random cut around the rip. The cuts can also move around to different locations
-Tried to cut the part before making the rip and cannot cut as errors are created when trying to execute the command.
-Lofted part as semi circle and then cut normal, some cuts are accurate, but others move around to different locations.
I'm using Inventor 2015 with SP2+
Hope this can be solved in the new release as Cut Normal would be a very handy function if it was 100% reliable
Edit: Screenshots added
Before
After (sketch and cuts visible)
@dshev199 , it appears that your part is a cone. What happens if you model it as a revolved surface (359.9° to leave a gap for unfolding) and thicken? Does the Cut Normal option work then?
Not suggesting that your modeling technique is the problem, but perhaps a different technique would work around the obvious Inventor shortcoming.

I'm pleased to say the 2016 release seems to have fixed these issues.
It pays to have the latest software release 🙂
