Arrangement linked to an expression
Arrangement linked to an expression
(OP)
Hi All,
Does anyone know of a way to link an arrangement to an expression in NX7.5? For instance I might have an expression that I want the value to change to either 1 or 0 based on what arrangement is active. Any other suggestions on how to do this would be appreciated.

RE: Arrangement linked to an expression
I have also come across this issue. However I would like to use an expression to drive the active arrangement.

RE: Arrangement linked to an expression
I have a parent assembly of a family of parts. The main variable that differs between the parts is the overall length of the assembly, which subsequently determines the number of components to use and their position. At the moment this is all driven by expressions, and while it works I don't find it particularly neat. In future I would like to use some of the components in other un-relate assemblies where the linked length expressions I am currently using to control the component position (in a master model approach) will no longer be relevant What I would like to do is have a set of assembly arrangements i.e. 'Short' & 'Long' which generate an expression variable that I can use to control the length and/or number of components in the assembly via if/else statements or similar.
I have tried using suppress by expression but I find that this will highlight the assembly mating constraints and show them as being erronous ("Reference objects have been deleted or suppressed"), while technically correct I would prefer it if these assembly constraints were suppressed (much like they are in arrangements).
Cheers,
Alex

Phew! Your predicament is quite difficult to understand based on the few lines pf text, I honestly can't work anything out from that I'm afraid. It certainly sounds like you are looking to something far more advanced than Legs11. Without actuallt seeing something, I don't think I can help sorry

RE: Arrangement linked to an expression
In your post above you mentioned that it's easy to make expressions arrangement specific. How would I go about doing that? While my final desired result may not be worth the effort and may be more easily achieved using two seperate assemblies having an expression driven by an arrangement will get me started.
