Transfered from EAP Ideas list. Also discussed during the SS3 beta.
Referencing by ACS matching would be very cool.
Currently, I think you have to:
1. In model to be referenced: Go to your 'Top' view, use Window Center and tentative to model 0,0,0. Save View as 'MyTop'.
2. In referencing model: Make ACS active, GA with Accudraw, turn on Active Plane lock, attach reference using 'MyTop' view, AX=,,
Would be great if there was a refaln.ma-like tool that would have an source:target matching boxes for the origins, rotation, scaling values.
When a Saved View is placed, Mstn uses the View of the View as the insertion point. This is not very helpful. Would be better if it would offer the referenced model's ACS' as the insertion point / rotation as an option.
With a few expressions , you could add +10m or -90 degrees to what ever the 'referenced' values were.

This would give Ref attachments a measure of much needed 'associativity': Making the insertion point/rotation more intelligent or 'info-centric' by linking it to 'named' feature-based 'locator' or 'connector'-type info and parameters, expressions, constraints-solving outputs is everyday practice in the MCAD and animation world. The old ways of attaching everything at the model global origin to keep alignment never really worked and is unsustainable in these BIM-crazy times. Seems to me that ACS' are the obvious first candidate.

Update 17 (10.17.00.209) introduces the ability to use AEC Transform while attaching an iModel.
Please note that this Idea is about mapping the incoming Ref attachement's Global Cooordinate System (GCS) to a user defined ACS. This is different to the above.
