How can I know the memory size of a TIN or DEM surface? I have a very dense points data to create a surface and I would like to test what option would be the best: simplify the surface removing points or make it raster...
One option would be to create the surface in a new, clean drawing. Then data shortcut in the surface to your project files. This will keep your drawing file sizes to a minimum and your memory usage down.
You could also copy the drawing with nothing but the surface in it and test the different methods of reducing the file size.
Credit where credit is due! Give kudos or accept as solution whenever you can.
Also, remember that the drawing size will be impacted by the surface style in use when last saved. For example, your saved drawing will be smaller if the surface style is a "No Display" style versus a style which displays contours and TIN lines.
Thanks guys, what you are suggesting can indicate the proportional impact of each surface... and maybe it should be good enough.
But I was expecting to calculate the TIN memory size by the number of triangles and its size in bytes vs the number of pixels and its size in bytes. So I guess I should write a VB code to be able to get the number of triangles (TIN) and valid pixels (DEM).
Isn't this the memory size of these ARX objects?
