So I do get behind now that I'm working for myself. I remember several years back Adobe and Bentley formed a corporate alliance (?), so I thought great, now I can use those georeferenced USGS quads right in my design file. All my stuff is georeferenced, most utilize government aerials, like Mr.SID, ECWs. But it never worked. I have to use my $300 GIS program (handles them fine), export what I want and reference the PNG, works.
Recently I've seen discussion about georeferenced PDFs, seems they do work. I noticed Microstation Connect R12 (me) lists a fix "967913 Resolved issue with Georeferenced PDF located incorrectly.". I just tried it, it comes in at 0,0, in what looks like meters the size of the hard copy. What am I doing wrong?

the pdfs are supposed to use wgs84 longlat..
so as far as I understand you need a gcs of your choosing set first in your active dgn then raster ref attach the pdf and use inherit to let it reproject on the fly over your active dgn..

Yea, that's my understanding as well. Been using geo-refed stuff quite a while. Pretty simple really. The PDFs just do not work. Did try a few different settings. Did not try creating a new DGN with a WGS coordinate system, as that is not desiarable. The cheapy GIS program I use handles PDFs just fine while set to projected NEZ US Survey Feet (local system).

maybe set your active dgn CGS and units to set to projected NEZ US Survey Feet (local system) then raster ref attach the pdf and use inherit... are you absolutely sure the pdf has a datum set to long lat , if it works in GIS it should have a datum long lat built in ?
this is starting to do my head in....
Are you able to find out the real coordinates of the pdf edge corners without mstn .. say the gis your using .. .then draw the box edges in mstn new file with the same datum as your box in long lat wgs84 , then attach your raster to this the outline should match the raster..
Now ref attach this new long lat to your drg nez local datum us feet, they should land in right spot...
Thanks for the comments.
My file is set to NEZ US Survey Feet, I've tried all the various combinations of settings (at time of attachment as well as Preferences) for attachment, nothing works. The PDFs are fine, they work (georeference) in other softwares. As far as manually positioning, I can do that, just don't think I should have to. Microstation does not read the georeference from the PDF.
Not a show stopper for me, I'm pretty used to doing it with the GIS program, which also makes it easier to do multiple adjacent multiple quads. Just caught my interest seeing discussions about georeferenced PDFs.
I think when the geo pdfs are created in msnt they dont have too many bells and whistles work both for other software to use the mstn created pdfs for other msnt usersI never had problems with these sort of pdfs todate...
I would seem now days the pdfs created from GIS software have more or better settings and things to look for to get them to project correctly...that mstn raster manager cant see or use...
Bumpity bump. Still can not get USGS 7.5' quad maps to come into a DGN in the correct coordinates. They work in othr softwares. Is this one on the list of Connect bugs? Should I be filing a Service Ticket (rarely helps)? Or is Bentley just going to ignore this?
