I am a boat designer and I have a question on the new Rhino 7. I purchased Rhino 4 and upgraded to 5 years ago but never really got into using it because I could not find a good way to display ruling lines on hull surfaces to verify they were truly developable. I took the course Rhino for marine designers but at the time I had the same problem, I could define a surface that the program told me was developable but there was no way I could find to verify this with the ruling lines. So the question is is there any way in Rhino 7 to view and edit the ruling lines of surfaces to make sure there is no crossing or intersecting lines which would indicate a problem with the surface unwrapping correctly.
Is there a plugin for Rhino that will calculate the Hydrostatics as well as a plugin for speed vrs HP or would I need to purchase another program such as Orca 3D which I also have an older version that I never used for anything since I never used the rhino.
