I am using LwmDraw4Beta. After I chenge the coasts how can I remove default shoreline.

Hi Kenan.If you look at the ASM code, you'll see a line like:VTPLayer 8, 0The first parameter is the Layer number ( 8 is usually shorelines ).The second parameter is the replace flag. If you change it to:VTPLayer 8, 1Whatever previous data was at Layer 8, within the LOD13 Areas your new line touches, will be erased. If you have more than 1 line in that LOD13 Area, just change the replace flag in the first instance, or your new lines may be erased.If you search the forum using:exclude vtpas keywords, and make sure the 'And' button is ticked, you'll get some discussions about excluding VTPs.And, now that you've made some progress with Ken's LWMDraw, it's a good time to review the FS2002 terrain SDK, to see what your code is actually doing.Dick
