Reversing the direction of a POINT SET is created in NX6
Reversing the direction of a POINT SET is created in NX6
(OP)
I'm currently creating surfaces on a model that has been created from GOM'd point cloud data. So far I have created datum planes at set distances to cut through the GOM model body, this then allows me to create a closed spline matched to the profile of the 'cut' surface. My next step is to create point sets, that will then allow me to create splines & eventually through curves that will allow me to create 6 surface profiles that will make up the blade profile.
So far, I have managed around 80% of the required point sets, but for some reason, the remaining point sets are being created on the reverse side of the aerofoil profile. I was thinking that there would be a simple fix like 'Reverse Direction' but after hours of trying various alternative methods, can't seem to find a solution. If anybody can decipher what I'm trying to ask, any help would be GREATLY appreciated.
Many thanks in advance.

I've tried using trim curve to do this, but it gives the same result in that it trims the 'reverse' side. I'm sure that there are work rounds for this operation, the fact that all the other splines have 'functioned' properly & I've got the result that I require has made it more of a task to find out why the remaining few won't.
John,
I've atached a model with some of the initial GOM'd data removed that you will hopefully be able to follow my process. A similar task has already been completed & I'm following the process set out in that model, so as mentioned previous, it's probably more for my own knowledge & future reference now.
If you follow the point sets in SURFACE_POINTS2_LAYER17, you'll see that all but the last point set has been applied to the required surface but Point Set (419) is on the reverse side. Again, any advice would be appreciated....this is driving me insane now!!

I notice that your section curves are degree 1 splines and your guide curves are degree 2 splines. If you have the option to use degree 3 splines (or higher) for both, you may get better results.

Thank you very much for your help. I'll give the tips a whirl. If you don't hear from me again on this one, take it that you've resolved my issue.....or it's all become too much
Thanks again,
