Make Solid From Survey Points

This command creates a solid model from survey points on the roof and floor plus a 3D perimeter polyline. This method applies to input data of relatively few data points compared to a point cloud. All the data points must be on the roof or floor and not the sides. The roof and floor points must be drawn on separate layers that the program prompts for in the options dialog.

The solid is built by modeling a surface from the roof points and a separate solid from the floor points. The surfaces are trimmed by the perimeter polyline and then stitched together with the perimeter polyline to make a watertight solid. The resulting solid is stored to the specified MDL file.

In the example shown here, points 1 to 6 are on the ROOF layer and points 7 to 12 are on the FLOOR layer. The perimeter polyline is shown in 3D between these points.
