Hi to all,
Find here some words and screenshots about my work around.
I hope it is informative. Since I am dutch, my english is far from superb, but I shall give it my best try.
First I make a side view of the car.
Then I create a loft with 5 curves. For that I make use of 1 curve which I than copy 4 times. These curves are modified mostly by the scaling function. I try to keep the form of these curves as close to each other as possible, so that the resulting surface is as smooth as possible.
After that the body around the wheels have to be made. Here the blend function between the curves is very useful.
N.B. to be able to change already trimmed surfaces afterwards, I always store curves and untrimmed surfaces in another file for back-up. If I am not happy with an already trimmed surface, I can simply replace this by the back-upped surface.
I cut the form at the fourth curve so that the top of the construction is gone.
Than I create surfaces for the windows.
The bonnet, front window, roof, rear window and trunk are created as one surface by the network function. Afterwards I cut these into separate surfaces. The front window is corrected so that it “starts” under the bonnet.
I fillet between that surface and the surface for the windows. Alternatively you can choose to off set both that surface and the window surface and blend these 2 together.
In fact after that the biggest job is done. I than create the lights, rims and all other details.
For rendering I choose KeyShot. I bought this in a package with Alibre, which works very well. This keyshot license is limited to importing only bip files. So I have to get from MOI into Keyshot with a conversion step.
For that there are 2 methods:
I can export from MOI to Simlab composer using a obj-file (important: I noticed that it is better to choose the option quad and triangles rather than the N-gons option. With N-gons I run into some trouble when there is text in the MOI file (in my situation, the text “concept 430” upon the license plates of the car. Using quad and triangle is trouble free. Perhaps this is a bug in Simlab. I do not know about the "triangles only" option.
Simlab composer can export a .bip file for Keyshot.
The other method is an export from MOI into Alibre, using a step file. Than Alibre can create the .bip file for Keyshot. Important here (mentioned already in other posts) is to leave the curves out of the export. Alibre cannot function with the curves.
That is it for now. I hope this rough description is useful. Off course there are many ways to get to the final result.
The more I work with MOI the more I like it!
