In the command GRADING>EDIT FEATURE LINE GRADING>INSERT ELEVATION POINT
I can specify the Increment value which is what I want but this only allows me to select one line. How can I select multiple lines and specify an increment value?
Solved! Go to Solution.
We talking polylines or feature lines? I'm assuming FL
When working with Feature Lines you can only edit one at a time.
You could create one to your liking a just copy it. Keeping in mind that the elevations will be the same.
Thanks for the reply.
Its just a collection of 3D PL's that I'm using to create the surface. They are all existing topo content so I quickly want to add more vertices to make it more accurate.
Another way would be to add Supplementing factors "Distance" on "Add Breaklines" dialog when adding to the surface definition. This will add a verticie to the triangulation along the 3d polys at a specified increment.
If you are trying to create the Existing ground, the previous solution is the answer.
If you are trying to put elevations from an existing surface onto them use features lines instead instead of using 3d polys.
Select all of your 3d polys - "Create Feature Lines from objects"
In the dialog check "Assign Elevations" In the next dialog, select the surface and make sure that the "Insert intermediate grade break points is checked"
This will create feature lines with a vertice everytime they cross a triangle on the existing ground surface.
