grid-dtms ("grd")

See this command in the command table.

To access this command:

Command Overview

Create a grid of points to represent the average, minimum or maximum elevations of points belonging to multiple (and potentially overlapping) wireframe surfaces.

Displays the Create Grid DTMs screen.

Command steps:

Ensure at least one wireframe object exists in memory.
Run this command.
The Grid DTMs screen displays.
To output the points to the current point object, choose Current Object. Otherwise, choose New Object, and add the name to the edit box.
The Grid Increment specifies the grid point spacing in the X and Y axes. Points will only be created where they lie over an included surface.
Where there are overlapping surfaces, both within a single wireframe, and/or between multiple wireframes, Combine Elevations chooses how the sample point elevation will be calculated. This can either be the minimum elevation encountered, the maximum elevation, or an average of all the elevations encountered.
The wireframe objects to be used to generate the point grid can be selected within the Objects list. These can either be selected by ticking the box next to the required wireframe name, or by using the pick arrow button, and then clicking on the wireframe in a 3D view.

Tip: Hover your cursor over a truncated object name to display it in full.
Select OK to generate points data.
