How to Generate High and Low Points on a Civil 3D Surface
Comments
Jerry Bartels of Autodesk covers the Civil 3D Toolbox command AECCDRAWSURFACEHIGHLOWPOINTS.
The command creates COGO points at High Points and Low Points on a Civil 3D surface or a portion of a surface.
From the Jerry's YouTube Channel.
and the Civil Imersion blog.
Sadly, this handy command is still NOT XREF aware. However, the surface can be a DREF.
The boundary you select must be an 2D polyline object in the current drawing too. No Parcels allowed.
Yes, in a complex surface you can get a lot of new COGO points.
Also left unsaid by Jerry is a reminder that you might want to set your current COGO point number in advance.
I always thought this would be more useful if you could choose to create only low points for example.
That would be handy for Catchment creation. As it is you just have to delete the high points which are separated by Style.
