Just noticed something with 2D Acad plans etc attached as Refs to dgn as 'platform' to construct solids on,
Even though these are carefully 'flattened' 2D drawings, extreme zoom-in shows that as Refs their bounding boxes are 3D, having a thickness of 0.2mm - 0.1mm above and below the plane. That's been misleading me, thinking the bounding 'box' would be just a flat 2D Shape-equivalent in same plane as the 2D drawing. So when clicking on the bounding box to move the Ref to an exact 'height, was anybody's guess which vertex I was picking - in any case never the drawing plane, as I thought.
This has explained some of the discrepancies I was getting. I spent a long time hunting for whatever wasn't properly flattened in the 2D.
Is this correct - that 2D Acad plans etc attached as Refs have 3D bounding boxes of thickness 0.2mm? Can it be eliminated?
Any answer?

dont use acad DWG files try converting to dgn and use that instead..

Good reasons to keep the source of the Refs as dwg - 2D Acad is so easy peasy to create and continually Edit In Place 2D profiles - MS is def clunky by comparison (not just because unfamiliiar to me) both for 2D creation and in its Activate procedure.
Hi Tom,
Since you mention that the dwg files are flattened and considered to be 2D, did you also set the Options to open these files in MicroStation and behave as 2D only? See picture below.
If those options are not set, MicroStation will assume the dwg file to contains 3D data and may act as such.Can you share an example (master and dwg reference), so that we can investigate?hth.Henk
That sounds promising, but I wasn't offered any such dialog while attaching the dwgs as Refs in MS (BD actually).
Nor do I see that dialog when opening the dwgs direct into MS (BD).
How do I get to that dialog?

When moving the reference, Lock onto an element in the reference, that way you are moving them to the elevation you want. When in 3D think 3D! Even the 2D lines have Z thickness when looking from Front You will never have a 2D plane or you would never see it in Front view or actually any other rotated view if they didn't have some thickness. If a line Weight is set to 0 pixels you wouldn't see it. Why it is set to a .2mm thickness might be your working unit settings but in 3D there is always some thickness. Just my opinion!
I Hope This Helps Someone Reading This! (Intergraph>PseudoStation>MicroStation user since 1980's)
When you first attach a DWG file as a reference you should find the Options button listed under the Cancel button on the Attach Reference dialog. Please note, that this will only appear after you have selected the DWG file that you are about to attach. Once you have clicked on the Options button a new dialog should appear showing these 2D options for Model Space and Paper Space.
