In a part file, I'm finding that for some reason when you create a blend, doesn't matter how simple, then create another blend that intersects that blend (may not just be an intersecting blend, haven't tried other ways), the second blend becomes a child of the first blend. This wouldn't be that big of a deal, but I'm using some If statements in Pro/Program to determine which blend will be suppressed, and which will be shown. If it's decided that the second blend is the one that should be shown, it's obviously an issue that the first blend's creation is skipped in the part's program and comes back with a failed feature. And I don't believe I referenced that first blend at any point in the creation of the second one as the first one was already suppressed when I created the second.
Does anybody know why the 2nd blend automatically becomes a child of the first and if there's a way around that? Took me like an hour to figure out that I wasn't doing something wrong, but that Creo was simply not allowing me to create an independent (from the first) second blend.
I even tried this in a blank part file to make sure I wasn't just complicating things in my somewhat more complex part file. Same thing, if you try to suppress the first, the second is suppressed as well.
Thanks in advance,
Can you upload the part?
I'm not quite sure how to do that actually. I'm finding it's not so much with blends in the same place.... as a simple box extrude does the same thing. I'm starting to think it's my first blend that's creating the problems because I tried to replace the second blend with just a box and it did the same thing. That's the only feature that I can't replace with another feature based on the if statements, the other features work fine.
I suggest to:
1.] create 1st blend
2.] suppress 1st blend
3.] create 2nd blend
4.] suppress 2nd blend
5.] apply and test Pro/PROGRAM
Thanks for the help Martin, if I can't figure this out, I'll hafta start from scratch and try this.... I was adding If statements into my Program as I added each possible blend.
Is it a solid blend? Surface blend? Not a lot of info here. Does the second reference geometry created by the first blend?
It sounds like you need to learn how to use the reference viewer. Or, redefine references on the second blend, and pay close attention to what references are used. I can't see Pro/E "automatically" making the second blend a child, unless it's a cut removing material from the first, or referencing some of the first's geometry.
