   Here goes:
   Microstation + GC V8i

   Trying to import a surface from Rhino into GC and use it to populate with points,

   Opened .3dm file in MS and saved it as .dgn
   ModelAttachment of .dgn file it's ok,
   Create 2 points and set the Range (seems) ok,
   bsplineSurface SelectElementsWithinRangeAndPromoteToFeature

   Surface doesn't show in GC and at the "Symbolic Diagram" showed as red, can't find anywhere a error message or something that explain what is going wrong.

   Any sharp pair of eyes - and mind - that can figure it out?

   

   (surface.txt is actually surface.dgn rename file extension)

   seems like "surface.dgn" is empty. this would indeed create an issue as gc can not yet do magic stunts :) don't know whether this is the same at your end or if it happened due to the .txt extension on the dgn-file while uploading. either way, do it again and just zip it!

   surface.dgn becomes a 2d-file when extension is renamed back so that's probably the issue. upload again please. on another note - if you took the bsplinesurface into ms via iges import it would have become a "smart surface", which is a different type of element to a bspline ditto even though they look the same. this might be why gc won't read it - try to drop it in ms (ms equivalent to "explode" in acad) and make sure it's of the "bspline surface" type in your dgn file.

   last one (and a kind of silly one at that): more than once I've forgotten to give the object a visible color in ms. this gives you black on black and similar things, i.e. it's there but you can't see it...

   That should narrow the problem to...my UNknowledge of MS;
   or something related with ms levels and any kind of filter gc uses
   in the zip file are the .dgn file and the original .3dm file;
   the .dgn file in ms shows and detects the surface as it should (Bspline Surface).

   on other note, when I try to export the surface from rhino in iges format and then import it in ms it just doesnt import anything.

   yeah...trimmed surfaces are not that easy to transport between interfaces. if you repeat the process with no trims it will work. try then to either build it without trimming or aim to do the trims in gc. how did you import into ms btw?

   also - a "zipfile.jpg" still is not a zip-file. just ZIP the dang thing !! :)
