Sketching in Assembly NX6
Sketching in Assembly NX6
(OP)
Why can't I constrain/dimension a sketch to multiple components on an assembly. I'm only able to pick edges of the component who's surface I used as the sketch plane (and I get a linked feature in the model tree). If I pick a datum plane as the sketch plane then no component edges can be picked. Note....The all edges will hilite with select filter set to "entire assy", but that option goes away for constraining and dimensioning. Any help would be appreciated.

Can you explain what you are trying to accomplish ?
RE: Sketching in Assembly NX6
You are right the "ENTIRE ASSEMBLY" option will not work in your case (sketch constraining).
As Jerry told Wave Linking is the one of the way out (in case of a top-down assembly).
Secondly (my apologies if i got it incorrect in case of NX6).... use Project Curve to reference the other component entities (ENTIRE ASSEMBLY option should work here ...at least this is the case in NX8).Also note to keep the CREATE INTERPART LINK option ON (this is just besides the ENTIRE ASSEMBLY option) if you want the constraints to be associative with the reference geometry.
In case it doesn't work (i am 50/50 sure on that as i have a feeling that perhaps the CREATE INTERPART LINK option came into picture after NX6) ...go with what Jerry told.Take a wave link and use it as a reference.
Do share the exact detail with us so we can provide other possible workarounds also.

I presume you are mentioning the skeleton modeling in PRO-E. In NX we create a top-level sketch which can be referenced out at all the component levels using wave linking.I worked on a heat condenser assembly 2 years back and followed the same procedure.Create the layout sketch at the top-assembly level and then reference out the entities at the component level (you need not take reference of the entire sketch but rather go for a selective selection too.)
Also NX provides you doing the same through interpart expression linking.
