DRAFTING QUESTION
DRAFTING QUESTION
(OP)
Is it possible to create a dimension in an assembly from a reference plan in a part ? For example: I want to create a dimension from a part to the web center of a beam, but I can't select any center line. Can I select the plan ???And how ?

RE: DRAFTING QUESTION
If you want to create constraints, it's best to work with planes for the type of geometry that you are describing. ("web" centerlines)
These have to be defined in the detail part. Nothing amiss once you've done that. I suggest that you create a plane, using the "planes between" function. You can create a plane with history on either side of your web, and then, using "planes between," you can put a symmetrical center plane between them, that will update if you change the thickness. It can then be referenced by the assembly constraints.
Remember to watch the tree when using the Assembly workbench. (make sure you are trying to create constraints with the main product - top object in tree - highlighted)
Hope that helps.

what i did was :
in the 3d i made all center points at the end of each beam.
project those point in drawing and create my dim.

RE: DRAFTING QUESTION
I have noticed in later versions, (primarily R15) that this function has either become buggy, or it doesn't work like that anymore.
Give it a try, though. That's how I used to dimension centerlines for parallel edges. If not, use the "bisecting line" function, and then dress it up to look like a centerline.
Wish I could make it easier...
