My team and I trying to create an accurate terrain model of our site for masterplanning. Problem is the site is massive. Whenever we import the CAD topography lines from the civil engineers, the compute slows down, has trouble processing the information and crashes. Even if we get a mesh, the program lags.
We were able to create a simplified model that got us the general idea of the topography, but lacks some of the information.
Do you have any advice to to achieve a terrain model that is more efficient yet accurate?
