Triangle Surface Element

The triangle surface element is used to add a triangulation into a project that has been originally created in another program (or Kubla Cubed project). The triangles cannot be edited once they are added to the project, all triangulation data needs to be imported from a file. The triangle surface supports importing data from LandXML (.xml), CAD (.dxf, .dwg) and Kubla Project files (.kcp).

The properties that are exposed for this element are summarised below.

	Mode This is used to specify if the surface should have cut, fill or both. Most commonly cut and fill will be specified. Offset The offset option is mostly used to add construction thicknesses by specifying a negative offset. The options are Off, Z or it allows you to offset the entire surface in X,Y and Z. This is useful for accommodating for a construction thickness or finding a balance. Side Batter The triangle surface boundary is joined to the ground by side slopes. The Side Batters (set as a ratio of vertical to horizontal), dictate the angle of these slopes. You can set the side batter to either External or Internal and specify different side batter angles for side slopes that cut into the ground and for those that fill into it. Turning side batter off will result in the triangle surface being joined to the ground with vertical sides. Between the Cut and Fill ratios is a double-arrow button which, when depressed, will synchronise Side Batters.
