Does anyone by chance know how to import / attach a reference file to specific Auxiliary Coordinates?
The problem I'm having upon importing the is that the reference gets place very far away from my drawing and is hard to find sometimes.
I'm using MicroStation AECOsim Building Designer V8i Select series 6.
While I can't tell you how to get your reference to a specific coordinate, and this may not work for every situation...When I attach a reference by "Top" instead of something like Coincident, it comes in (in plan view) "on" my cursor. That way I can place it closer to wherever I want it.
The issue with attaching references while an ACS is active, is that the ACS has redefined the coordinates for the drawing plane, and the reference is trying to attach to "the right coordinates. If I am working on something that in World coordinates is at 50000,50000 and I set my ACS so that the origin is at that point, Microstation "reads" that point as 0,0. Now anything I reference is going to come in at the "new" 50000,50000 which is very far away from where I am working.

Hello MaryB, thanks for the the tip on using Top. I had to change my title block reference to a 3D model to access Top as a choice. But it worked very well. I am still confused on using Coincident and World coordinates I need to study this a bit more. Thanks!
Actually, my 2D drawings have "Top" as an option (but nothing else) but I am using Microstation and Geopak. It's possible that AECOsim works a little differently.
As I understand it, Coincident lines up the coordinates of a file, so that 5000,5000 ends up at 5000,5000. Coincident World lines up the Global Origins so that 0,0 lines up with 0,0. If all of your files use the same seed and the same origin and the same units, they look exactly the same. But they can look very different depending on unit settings and defined origin. Here are a couple of articles that touch on those concepts, and you can probably search here and in the Wiki for much better explanation.https://communities.bentley.com/other/old_site_member_blogs/bentley_employees/b/tim_hickmans_blog/posts/it-aint-the-same-old-originhttps://communities.bentley.com/products/microstation/w/askinga/1408/difference-between-coincident-and-coincident-world
This all gets a little more convoluted when using an ACS - Auxiliary Coordinate System. An ACS sets up a temporary coordinate system "over" your design plane, and while the ACS is active, Microstation will use those coordinates instead of the design plane coordinates.
If you have defined your ACS so that your "origin" is set to 5000,5000 that's the spot that Microstation "thinks" is 0,0. Any reference attachments will line up with those coordinates (not the real ones). If you attach a reference to your ACS "Coincident", the reference 5000,5000 will line up with the ACS 5000,5000 (which is now 5000+ units away from the "world" coordinates). If you try to attach the reference "Coincident World" is will line up the reference 0,0 with the ACS 0,0 (which is now at "world" 5000,5000). Either way, it comes in at an unexpected place.
ACS can be useful, but we do need to be very aware of them when attaching references. The Coordinate System part of an ACS affects anything that depends on coordinates.
Hi Luke,
A very quick way to find a reference that is far away is to set the Fit View tool to Reference, this may be all you need.
For background on working with real-world positioning that is particularly relevant to AECOsim (and continues to be equally relevant to OpenBuildings) please refer to: Series Index - Setting Up in the Real World
