mike46 Posted February 11, 2003 Share Posted February 11, 2003 Hi I am attempting a stie model for the first time and have made several experimental versions to try getting the hang of it I created a new layer on which to input the source data and tried the grid entry and 2d poly the grid method seemd to work best for me so I set up a new one with real data on a new layer after entering all the heights the site model dialog box has the layer options greyed out and has the experimental layer refrenced in it which I can't change so if i click ok it uses the data on the exp layer instead of the new one. can I fix this and what did i do wrong ?? thanks Mike Quote Link to comment
Guest Posted February 11, 2003 Share Posted February 11, 2003 You can't have two existing DTM's in one specific file. You can update an existing DTM once one is created, or you can create a proposed DTM. A proposed DTM displays changes you plan on making to the existing after doing cut and fill or something of the likes. If you want to create an existing DTM using the good data, you will need to do so in a new file. Quote Link to comment
