CATIA Surface-modeling
Tutorial 2A
– Import 2D outline drawing into Catia
– Build 3D curves based on the imported drawing
– Build the upper surfaces of the mouse (by Generative Shape
Design)
Tutorial 2B
– Do the draft analysis to search any undercut portion on the
upper surfaces
– Adjust the curvature of the problem surface manually
– Build the lower surfaces of the mouse
– Convert the surfaces into a solid
Tutorial 2C
– Build the parting surfaces based on the imported drawing
– Create components from the finished model
– Re-assemble the components into a product
– Modify the outlook of the master model and then get all
components updated automatically
Please be reminded that this series of tutorials is designed to demonstrate a design
approach with CATIA, rather than the command itself.
