I have a 3D DXF file that came from a Prodim Proliner.
It is from a boat deck/floor that has a slight curve/arch across the entirety.
I imported the DXF into Rhino, and the curvature is evident. However, there are no ‘Z’ lines which I have been reading about.
Also, the orientation on the DXF does not match up with the typical X,Y,Z zero.
Is there an easy way to line the DXF up with 0,0,0?
Is there an easy way to take the DXF and flatten it/unroll it?
Do I need ‘Z’ lines?
Is there a tutorial for this that I have yet to find?
Thanks in advance for any help.
I have attached the DXF in question.24.dxf (70.1 KB)
Hello - is this, more or less, what you are after?

I need it to be flat, like that, but I need to account for the added material that makes up the ‘Z’ height.
It looks like you basically made a flat version of the DXF I provided, without accounting for the extra material.
The material itself will be larger than the drawing you provided.
I’m not sure of the best way to explain what I’m trying to say above.
Hello - that is the idea here - you can make a better approximation of the base surface than I made - it is likely an extruded arc, or nearly, but if you get that close, then
Squish should unroll the surface and the curves to a pretty good approximation.
Can you provide me with your process so I can test it?
I am brand new to Rhino. I typically use Vectric for my vector editing. This is the first time I have attempted to account for a curved surface.
Thanks for your help!
I’ve consulted for people doing exactly what you are and I told them to tidy up the input in to a clean polyline and use Patch to get a surface you can UnrollSrf or Smash. The deck is probably very close to developable and SeaDeck isn’t, so doing this on a piece-by-piece basis might not be a bad idea.
I have a cleaned up DXF, but it loses the 3D data when I edit it in Vectric.
As far as being developable, I believe you are correct. The decking material actually isn’t SeaDek, it’s a more rigid ‘PlasTeak’ if I recall correctly.
I am just digitizing the boat for the man so he can send it off to be cut. I’m just not sure that my digital file is accurate enough in a ‘2d’ version, so I’d like to use the ‘3D’ version, and flatten it to account for the curve/arc on the deck.
Hi Jim - I used Patch in my quick test but I suppose there is better info available on the underlying shape, the patch did not look too convincing other than as a test of the process.
yeah I think it required a good bit of tweaking the settings to get a nice approximation…
