Civil 3D tools

Hi, is it possible to do thiessen polygon, I saw a video on youtube but i did not found the tools option?

Can we also do a groundwater level and water direction like surfer software can do?

thank you

Hi @Anonymous

I could be wrong if anyone wants to correct me but I don't believe Civil 3D or AutoCAD Map can do this out of the box.

I know with previous versions you have to use 3rd party plugins to do this.

If anyone is aware of this being added more recently please comment.

If you can give us the link to the youtube video we can tell you if they are using a plugin or not.

This will be a plugin in the youtube video.

They are using Civil 3D 2012 which doesnt have thiessen polygon.

Please see this forum post for the same issue and may have some usefull links to plugins if they still work:

Turn on slope arrow in surface styles for the direction.

No idea about the polygons.

This has been added to DotSoft's C3DTools add-on package.  Simply select points (or CogoPoints) and the exterior boundary to generate the interior linework with no overlaps (as shown) or a collection of closed polygons.
