Need help converting 2D drawing to Rhino8 3D

I’m a newbie. Have been using a 2D program for over 20 years. Now I have to go to 3D to use a 3D printer for manufacture. I saved a three-view drawing in DXF format, then opened it in Rhino8. All I get is the top, front, side, and perspective views of the flat drawing. How can I separate and put the top view into the top window, front view into the front window, and etcetera. Or can that be done?

Can you show us a screenshot of what you have?

I’m not sure which application you are using.
You post in the iRhino category - iRhino is a viewer only and won’t let you change your geometry.
I haven’t heard of Rhino8 before.

If you are using Rhino 5, you should be able to use RemapCPlane to put your side view geometry to the right viewport, and front geometry to the front viewport.
