My firm is working on a masterplanning project with a 4 sq. mile site outside of Riyadh, Saudi Arabia. We recieved LiDAR scan data (.asc files), which we were able bring into Infraworks as Rasters that formed a Terrain surface.
I have exported an IMX file from Infraworks and been able to open that into Civil 3D, but when i try to save the dwg, i get a message thatthe file is too big and so it is creating an .mms file that must be kept alongside the .dwg file.
When i re-open the dwg file, the mms file is not loaded, and when i use the READ MMS FILE command, it says there is no surface.

I was using UTM84-38N for the coordinate system - both for the model, the imported LiDAR terrain and the surface imagery. the LiDAR based terrain seemed to come in at the right location (when zooming out in the concept model, the topo was exactly where i would expect it on the globe), but surface imagery was clearly off when i tried importing it. and then when importing to Civil 3D, when assigning the coordinate system to UTM84-38N, i got the error message that i wasn't using the correct coordinate system.
i have come to the same conclusion about sketchup, and we are now trying o figure how to best use infraworks itself - importing sketchup model into it.... but it seems every single building needs to be modeled in separate files for the draping to work right - otherwise, some buildings get burried, an others float....
The .mms file was visible in windows (in the same folder as the dwg), and it did have a size. the original LiDAR scan resulted in an .mmsw file of 13.5 GB, while the crpped down site yielded an .mms file of 4.5 GB. Like i said - its a BIG site.
Can you try and create a new model in InfraWorks with database CS = LL84 and just import the image to see if it placed in the right location. The image needs to be georeferenced, for example with a world file.
The reason why your 3D model file (sketchup) is place correctly in on part but on the other end it's misplaced is, because InfraWorks handles the file as one file with one reference point. The reference point will be placed correctly, but the larger the 3D file is the more offset you get due to earth curvature, CS settings, etc.
Regarding to the surface file, sometimes it's a better workflow if you create an 32bit elevation image file. It is possible to do that in Civil 3D: Load the complete surface, then export as DEM (image) file.
