perpendicular lines tied to centerline profile elevation

Treebeard

Is there a way to pin perpendicular sections to the centerline elevation? I am trying to establish a swath width of perpendiculars that horizontally extend from the main profile, at the profile elevation. The first figure is the profile and the second figure is meant to show a "level" section pinned to the profile elevation.

Hi Treebeard.

I'm not sure if I understand your question entirely. I think you are asking if GM can cut cross-sections along a sloping design profile line? If so, the answer is yes, as shown by screen grabs below.

The simplified workflow is as follows:

1. Create your design profile or line with design elevations.
2. Buffer it at required width (50 m in examples below).
3. Select buffer area and create flattened terrain from selected area (as shown in Screengrab No. 1 below).
4. Select your design profile line and create "Perpendicular Profiles" i.e. cross-sections form the Path Profile Settings toolbox at required spacings (25 m spacings below) and required swath widths (80 m width in example below).

You can then toggle backwards and forward along design line using the left and right arrow buttons on the profile box header. I've shown cross-section for Chainage 0 m, 25 m and 50 m below...

Let me know if this answers your question or if you need further help.

cheers,

Etc. Etc.

Perfect! Thanks so much for the workflow!
