Engineering application-data file generated by elevation points-elevation points without coding. When operating, you need to specify the name of the layer where the elevation value note text is located. The layer must only have elevation points and elevation note text, and cannot contain other graphic elements and text notes. Select the elevation value.

If the elevation points and elevation text annotation layers are not independent layers, but have been merged with other graphic elements and text annotations into one layer, you need to manually extract the independent elevation points and text annotations into independent layers. Or use the designated point function of engineering application to generate data files, click each elevation point one by one with the mouse, and input elevation values at the same time.
