Tin triangulating incorrectly - corridor modeler
I am working on our final model for the dtm, finished grade tin, and top of dirt tin in Geopak SS2 Roadway Designer. I recently had to create additional templates to aid in the top of dirt surface creation. In doing so, somehow now my top of surface tin…
Geopak - creating a TIN with csv file
For some reason I'm having trouble getting my csv file to translate into a DTM model/TIN file. Yesterday it seemed to be working just fine, but no matter which avenue I'm taking it never seems to load correctly and I'm stuck without a TIN. What steps…
Discrepancies converting existing ground TIN to DTM for use in Roadway Designer
I noticed an issue with end conditions not tying into the existing ground line drawn in cross section cells. The problem occurred at several cross section and the error varied between 0.01' to upwards of 2'. After troubleshooting, it was noticed that…
RE: TIN Shift when Converting DTM
If it is an issue with the units, I'm not sure why it will display correctly when I am using the original DTM file. Just in case, I created a DGN file with SF units (the original had plain Feet) and then tried to convert the DTM to a TIN file again, but…

Re: Convert LIDAR data
Extract XYZ should work but does not provide the filtering and thinning that you desire. You would end up with all umpteen gajillion points, when what you really want to do is thin the number of points to a managable size.
My experience with the…
Re: Power Civil: LIDAR thinning
Neil - 2.5 million points is a fairly huge DTM. Not sure who advised you that you should be able to do 30 million. WIll PowerCivil do 30 milliion? Maybe, but probably not on a 2GB machine. Don't forget that your operating system and other processes will…
