![]() ![]() With Civil 3D 2009, once your surface grows to 2.5 million TIN points an external MMS (Memory Map Surface) file will be created to handle the large dataset. Once your surface grew to be above this level the recommendation was to break up the surface into multiple drawings. Previous versions of Civil 3D (prior to 2009) supported only a surface model with roughly one million TIN points. ![]() How much data is too much? How do we pare down the data so that it is usable in AutoCAD Civil 3D without compromising its integrity? Can we really use LIDAR data in Civil 3D? I will be explaining multiple ways that you can pare down your data so that it can be used in Civil 3D and still output an extremely accurate surface model for engineering design. This is great news for our engineering designs, but having a lot of data can be problematic when it comes to importing it into design software. In today’s land surveying and civil engineering world we find that with the advancement of technology we are able to collect larger and more accurate amounts of data from the field in a shorter timeframe.
