CAD drafting Surface Difference 6 Command line: PC_HEIGHT_DIFFERENCE

 

The Surface Difference command creates a new surface by subtracting one surface from another by height.

CAD software Surface Difference 7

The source surfaces can be a SubDMesh or a PolyfaceMesh.

The resulting surface is obtained by combining the points of the first and second surfaces, preserving their X and Y coordinates. The Z coordinate is calculated as Z of the first plane minus Z of the second plane. Since the X and Y coordinates of the points of the first and second surfaces do not coincide, then in fact the Z coordinate of the points of the new surface is calculated as the difference between the Z coordinates of the existing points of one or another surface and the Z coordinates of the intersection of perpendiculars from these points with the other surface.

The command has no options. To perform it, you only need to specify the source mesh.

The command is applicable to obtain a height map with a legend: the resulting surface can be colored by height using the Coloring the Mesh by Height command and generate a legend using the Formation of a Legend command.
