Toes and Crests (Preliminary)

Source file: preliminary-toes-and-crests.htm

Create preliminary toes and crests is used to determine and create breaklines automatically from a triangulation.

Tip: Best results are achieved using a triangulation with an even distribution of triangles: use Fusion Surface.

Select the relevant surface.

Note: Do not use a simplified surface.
Apply a uniform colour to the surface (see Uniform).
On the Create ribbon tab, go to the Topology group. From the Toes and Crests drop-down list, select Preliminary.
Select a triangle in an open area on the surface. This will display lines representing toes and crests based on the defined Intersection angle.

Tip: Press 9 to make the line thicker and more visible.
Adjust the angle to achieve the best result.

Tip: Increase the Intersection angle to create lines higher up walls and cross obstructions.
Select Apply.
To fill in areas that have been missed, click in the Bench facet field, then click on benches that have not had toes and crests created.
Once all preliminary toes and crests are created, exit the tool.

The result of the Preliminary function is saved in the cad container, in a container with the triangulation name. Inside this container are two containers named recommended and other:

recommended contains the results considered to be the most accurate.
other contains results that can be of use. These results are colour coded in red through to green, indicating the level of confidence.

Note:

Create smart lines can be used to fill in any areas that are not clearly defined by preliminary toes and crests.

Drag any lines to be kept from the other container to the recommended container. Delete the rest.
Edit any incorrect line segments by selecting their points and pressing Delete.
