Exporting for Machine Control Systems
Each producer of machine control systems provides their own software for preparing a file that can be uploaded to earthmoving machinery. Many of these software products support the import of both CAD (.dwg, .dxf) and Land XML (.xml) files. Therefore, you can export all your data to either of those formats, and it should import seamlessly.
To do this, navigate to:
File → Export → CAD Data
or
File → Export → Land XML
Sometimes, machine control systems work better with one format over another. It has been suggested CAD files work better for line work, while Land XML files for TINS. However, it is easier to stick to one file format unless there problems arise.
It's worth noting, some older machine control systems may not support TINS but do support point clouds. In such cases, you will need to generate gridded data in the same way as suggested for BIM Software that does not support TIN.
