Surface-modeling

Tutorial 8A
– – Insert 2d pictures and reposition them on offset planes Create 3Dcontrol curves

Design with a Master model

Not For Commercial Use

Tutorial 8B,C, D
– – – – Create the front body of the master model Create the middle body of the master model Create the rear body of the master model Create parting surfaces

Tutorial 8E
– – Split the finished (master) model into separate parts Build more details on each part

Tutorial 8F
– Reassemble them together

Please bereminded that this series of tutorials is designed to demonstrate a design approach with CATIA, rather than the command itself.

Tutorial 8A
• Create a new project folder (e.g. C:\Car_R8)
Pic1.jpg Pic2.jpg

Before Start: http://models.audiusa.com/r8 • Crop thepicture (972.jpg) into two jpeg files in a square size (just extracting four views: front, left, top & back) • Save the files into the project folder
