Need help creating a 3D surface to be used with InRoads. Starting odd with a large .tif fileI have been asked to set up the 3D model of the existing surface so it can be use in design of a new highway (using InRoads). I have been provided with a TIFF image which is >1GB so I had someone clip it for me in ArcGIS, assuming the size was the reason why MicroStation wouldn't read it. (error message: out of memory")
I still can't seem to figure it out and have wasted an immense amount of time trying. I am assuming I need to use MicroStation to open and convert the file then can proceed to InRoads. I also have shape f8iles of the proposed alignments I would like to overlay but one step at a time.
Any help/feedback is appreciated. Thanks
(I am using MicroStation V8i SELECTseries 3)
