Hi I have a question about Rhino 3D software and in general 3D modeling. First i think, i should draw my vehicle from 4 views in rhino:back,front,top,side. How and with which special tool before scanning a sketch i can draw it first because all ratios should be the same in each views i'm gonna use.
In my opinion, you should fisrt draw the plans of your vehicle on some tracing paper at the scale you want (the bigger will be the most precise, but if the plans are too big, you won't be able to scan them...). Using tacing paper, you can check the proportions are the same on each view. Then scan your plans at a same resolution.
Otherwise, just scan your sketches, than import them in photoshop in the same resolution (for ex: 150pp) and rescale them so the proportions of all your skecths are the same.
If you want to use your sketchs 'cause they're not clean enough to be used them as global "plans", import them in illustrator, and re-make the lines of your sketche with the path tool. You can import all the views on the same document, so you make sure the proportions are right, using the rulers to check the alignment of the different view.
I would personnaly use the last method cause its fast, easy to check everything, and your plans will be realy clean. & you can print them the size you want, if you have to make a model then...
If it's just for a fast modelling, the first and second method are ok.
It's fairly simple to input an image as a reference in Rhino using BackgroundBitmap Place command.
But in general what counts is the accuracy and proportionally correct reference images.
You may achieve it by hand if you have some drafting experience and a decent scanner and image editing software or simply digitally drawing in a 2d/3d package.
I use both methods and most of the times I simply draw from scratch in a 3D package like Maya or StudioTools. You can define the constraints, max length, height, wheelbase, hard points etc importing human models as for ergonomic checking or seeing the impact of different wheels and tires on your design and its stands if you have a library of commonly using wheels and tires or your custom designs.
Anyway some basic knowledge of resizing images in Photoshop would result in really good proportionally accurate references which can be imported into almost every 3d or CAD package.
Rhino itself is good and light as well for your purpose.

How can i learn these knowledges?introduce me some good toturials if you know, e.g. Teaching CDs or web based toturials. Meanwhile you can send your post in persian.
