Slope Surface

The function calculates the slope from a selected polyline in the drawing. It draws the slope, and returns calculated volumes for cut and fill. You are free to use an active triangulation towards terrain or calculation towards an existing grid file of a terrain layer, as a calculation method.

Group and feature code settings are important when calculating more than one set of slopes that have interactions with each other and if the slope calculations are to be saved to the terrain model. It is also important to give correct priority to the groups being used for slope calculations, in most cases priority 1 if the terrain surface has priority 0.

In the case of having groups for surfaces with several priorities and several subsurface levels, the slope calculation function will automatically calculate triangles for each priority and level. The only thing the user has to control is that the correct groups in the terrain model are active.

Working Process

Note: You can skip steps 1 and 2. There will then be generated a unique name and a Slope Parameter Set template, automatically.

The slope calculation function uses AutoCAD Tool pallet technology and the user can edit parameters and edit the polyline at the same time as well as use all AutoCAD standard functions.

The function Slope Surfaces is included in Novapoint's Landscape, Terrain, Road Professional, and Civil Construction modules. Run the function; the palate Slope Surface will be docked on the left side of the screen. Press and hold down the left mouse button over the double lines at the top of the palate to move it. The upper part of the palate shows the different types of parameters and settings that are available for the function. Select each type of setting by pointing at the text.
