Toes and Crests from Points

Source file: toes-and-crest-from-points.htm

This function creates four sets of lines representing the Crests, Toes, Top of rill and Bottom of rill lines within a pit.

The input data showing the pit can be a set of points, scans or surfaces. The results are saved to individual toes and crests containers under the cad container.

1. Import the pit data into a new view window.

   

2. Select the pit scan in the project explorer.

3. On the Labs ribbon tab, go to the Create group and select Toes and Crests from Points.

   

Main input panel - specify pit centre and continue with creating lines.

4. Specify the Pit centre to determine the shape of the pit from the drop-down list by selecting either:

   • By points: Place the cursor into the first row, click at least two points in the pit base to draw a line running along its centre.
   • By edge chain: From the project explorer drag the edge chain into the field. 

5. Change the output line colours according to preference via the colour boxes. Either single click for the standard colours, or double click for more advanced colour choices.

6. Click OK or Apply to complete the function.

The results are saved in the cad container.

Each of the line sets is also in a separate sub-container in the cad container. Select the four toes, crests and rills containers and view them in separate windows.

                               

Crests and toes lines (pink and red lines), each saved in its own container.
