Model relation request of drawing parameter

[athomasen]

How come this, in model relations, doesn't work?

MODEL_PARAMETER = DRAWING_PARAMETER:D

I would like to have a part parameter refering to a specific paramter of its active drawing.

Say for instance "PTC_WM_ITERATION"

So the part has information about its drawing iteration value

How to do?

Hi,

   you can try the tree columns in the model tree navigator

   and then choose the type "Database Params",and the select the PTM_WM_ITERATION to display in the model tree columns

   but before the steps,you should ensure the parts is from your company windchill system

Hi

Ok, but how to automatize this in model relation?

A Part does not belong to a single drawing, therefore, which drawing parameter would be assigned to the part parameter?  Imagine creating two drawings for the same part and those drawings are both in session (active).  Which would be used to populate the part parameter?  This is the reason we have component ID's in drawing mode.  Drawings can have multiple components associated to them simultaneously, thus we need component ID's to distinguish between them.

Drawings are children of parts (and assemblies).  I think that is why you can't do what you are asking.

I believe it is better practice for the drawing to know the version of the objects it depends on, rather than the objects be aware of the versions of the drawings they are part of. (I apologize for the poor grammar)
