Usually, a scanner produces more than a point cloud. Usually the data is ordered in rows and columns. If this is the case, you can import each data set as a mesh surface. If you have an STL file, you can import it as an STL surface. There are other ways to import a polygon surface into TrueGrid® , but I am guessing that if you have a polygon data set, it will be in one of these two formats.
If your data is truely a point cloud with no structure, then you need a specialize software to construct a polygon surface from the points cloud.
All surface types in TrueGrid® work the same within TrueGrid® . There are no special cases. As soon as you learn the basics of TrueGrid® you will know how to use these surfaces to build a mesh.
A special note: You may have many surfaces created by the scanner. In this case you will probably want to use composite surfaces in TrueGrid® . It is simple in TrueGrid® to form a composite surface from a collection of smaller surfaces. On the other hand, if you have a STL file, it may be only one surface with many features. This can be awkward because you will not be able to take advantage of some of TrueGrid®'s powerful features. In this case you may wish to break the large STL surface into smaller surfaces along feature lines. This is also possible within TrueGrid® .
