Command description:
Point entities selected will be projected onto the mesh to calculate the Z difference between each point elevation and the projected point elevation. The average difference will be calculated by dividing the sum of all calculated differences by the total number of points processed. This average z difference will be added to the mesh vertices elevation, moving the entire mesh up or down. The goal is to minimize the z differences from the control points to the mesh.
A table will be created in the text screen showing the calculated z differences and final elevation from the control points. An example of this table is as follows:
***********MESH VERTEX ELEVATION ADJUSTMENT TO CONTROL POINTS***********
(2) valid control points. (0) invalid control points.
AVERAGE Z DIFFERENCE: -0.7500

Select control points:
Tips:
•Before using this command you must draw regular point entities to select them as control points.
•The control points are usually measured on-site and are used to assess the accuracy of a photogrammetric or LIDAR survey.
•You can press the F2 key to display the AutoCAD text screen, and copy the z differences table to paste it into a text editor.
