Hi Matadem, one way is to export your curves to DXF or PDF formats, and then open the DXF or PDF file back into MOI.

You can also use the Make2D command which will generate a 2D drawing like DXF/SVG/PDF output but insert the 2D vectors into MOI instead of into the external file.

To run Make2D type the Tab key, then type Make2D and push Enter.

There's also a related new command in v5 called ViewProject which will generate a projection of the objects but not completely flatten it so that it can process a solid into another solid.

But you probably want to use Make2D for what you show.
