What program did you use to create it?

Please post all the details and the file.

Thank you.
Step 1 : Create the outlay

Step 2 : Create sections along the profile.

Step 3 : Connect all the loose ends of the sections to create a second guide.

Step 4 : Multi section surface

Step 5 : Redo most steps for engine cover. Be careful to ensure tangency at the seam for aesthetic purpose.

Step 6 : Use mirror function (though for printing I think it would be a nice place to divide the model)

Step 7 : Do a thick shell

Step 8 : Prepare the front lights with a profile

Step 9 : Do a revolution on the profile of step 8

Step 11 : Do the profiles for the wheel cover

Its these kind of things that really show the power of the graphical 3D Design tools! I don't think OpenScad can do this stuff so easily.

I wish LambdFF would get back here. All I've got at the moment is a 2D shape for the body in one plane. I need to know how to make the curves to make surfaces in 3 planes.

The download has the body suitable for printing doesn't it. Both the STL and the IGS seem OK.

Hi EMU. Sorry for the delay. On a good note I am now a father (again) and both my wife and son are OK. On a less good note, my CAD soft is CATIA. I'm not familiar with RHINO.

However, here is a bit of advice : if you look at step 1, I just designed a single line, not a section.
-> this allowed me to use a function that creates a plane at a given point , perpendicular to the tangent of the curb. From what I see in the rhino documentation, it seems what you are looking for is CPLANE
http://docs.mcneel.com/rhino/5/help/...nds/cplane.htm

Once i had those planes on several key points of the profile line, it was possible to do the sections.

On the STL I uploaded I think I gave the hull a 3mm thickness and the overall thing about 200mm height. Figured it would make it printable for most printers.

Can't model and scan - I don't have a scanner. Besides, creating the object with CAD is half the fun of making an actual object.

That's a good idea about using a zero-turn mower if one ever made a person-carrying vehicle, but, unfortunately, Mercier is unknown to most people because he was working in the 50s & 60s and the adults of those times are mainly plucking harps.The significance would be lost on Gen Y. I remember him because I was introduced to his work when I was a child, and I'm a nostalgiaphile.
