face blend multiple sheets

[whaley01]

I just moved from nx6 to nx 7.5, I dont know if i am missing or dont have something checked right. But can you create a multiple face blend without having to sew the sheets together first. In the last rev (6.0) I could.

Yes you are right. I dont know why the development team took off this freedom. Freeform modellers like me dont appreciate it. I always try to keep less features in the part navigator and one sew at the end. It gives me a better control while making design changes.

The surfaces which make up each set must form a single sheet body. Therefore, if there are multiple surfaces/sheet bodies, they must first be sewn together. You can still create a Face Blend BETWEEN unsewn sets, but the sets themselves must each be a single sheet.

This was changed sp that both 2-Face and 3-Face Blending could be accommodated in the same function and still have a consistent workflow. Besides, it's considered a best-practice to have a single sheet defining a set since it eliminates having to include additional checking and hidden operations inside of the blending code. If there are going to be any issues getting a valid sheet body from multiple surfaces it's best to handle those issues in a function designed specifically for that purpose, i.e. 'Sew'.
