Converting surface to matrix of values

[Anonymous]

Hi, I was wondering if I can recreate a CAD model in MATLAB or Jupyter Notebook, and I was thinking about using mesh() to plot the surface. However, I don't know if there's a way to parse a surface in CAD so it becomes a matrix of values. Thanks!

Hi Yuchen,

It is not possible in plain AutoCAD at least without programming.
Civil 3D can make this for sure, but it is a separate application which is available only on PC, not on Mac.

Hi Maxim,

Thank you so much for your response! I actually have access to a PC with Civil 3D, so I was wondering can you tell how to do this in AutoCAD Civil? Thank you so much, I really appreciate it!

I'm not Civil 3D specialist, but you can ask your question on Civil 3D Forum.
Here are a couple of posts related to your question (as I think):
