I'm using Revit 2011 and am modeling a large development with a "projected area" of 305k m2. I've felt like I've been pretty conservative with the amount of points I've included, but still my i7 930 workstation is chugging with every point modification. I've tried the "simplify surface" command, with a precision of 75%, twice, but without any noticeable improvement.
Is the performance hit due to the area of the toposurface or the number of points?
Besides a faster processor, can you suggest any way to improve performance? Every time I add or move a point it takes upwards of 15 seconds to refresh, which can get tedious with a site this large.
Thanks,
James
