Calculating volumes, creating contours, and creating profiles are all tasks that are performed on surfaces, which must be loaded in memory. Multiple surfaces may be loaded at once. On the other hand, if you are working with a large volume of points, you can optimize performance by closing unnecessary surfaces.
The general surface interface makes it possible to view all the surfaces saved in the Vision database as well as how many points, breaklines, and triangles they contain. In this interface, it is possible to add, delete, copy, move to the solids section, and merge surfaces quickly by first selecting them from the table and then choosing the function.
The button is used to update surfaces drawn in the main window, if modifications were made without redrawing it.
Note: This function does not update the points, outlines, or breaklines, only drawn triangulation.
The Erase button is used to erase all elements from the main window.
The button is used to merge two surfaces together. When merging, there are three options:
Include all points from each surface.
Give one surface priority and incorporate the points from the second surface that are outside the first one's outline.
View cross-sections along an alignment and choose views on the surface given priority.
It’s also possible to fuse surfaces as layers of another layer. For this option to work, all XY points needs to have their concordance in each surface.
The "Determine and show elevations" section is used to apply the elevation of COGO points or points picked in CAD to different surfaces. Simply select the desired surface from the table, then select the points either on the screen or by point groups. It will generate an elevation report that can be saved as a text file.
