To query surface intersections

The Surface intersections query is used to create an edge network at the point of intersection of surfaces.

1. Highlight two or more surfaces in the project explorer.

2. On the Query ribbon tab navigate to the Surface group and select Surface Intersections.

   
   

An edge network is saved in a cad container named intersection lines of surface1 and surface2, or similar, depending on the number of surfaces queried. You can nominate to store a number of the largest intersections as separate objects (named intersection line 0, intersection line 1, etc.). The remainder are combined together into one object named remainder.

This function is useful for determining differences between regions, particularly when solid volumes are not suited to the calculations. You can also use it for other options e.g. explode and then use one of the loops to crop by polygon.

Above is an example of a query of Surface Intersection.
