Surface with .mms file export doesn't work

[Anonymous]

Hi,

I have created surface from around 8 milion points. I got 2,15 MB dwg file + 534 MB mms file.

Now I have this surface style set to "Border and countour lines (1 meter step)" and I need to export it to plain Autocad. Export goes right but there is only the border in exported dwg. There are NO countour lines - I need to get those 3D polylines...

What should I do? How to export dwg+mms surface?

Thank you for any advice!

Peter

Petr,
Welcome to the Autodesk Forums.
You'll need to first Extract the Contours from your Surface. Good video by @Jeew-m >>>Here<<<.
