Catia Parametrically model a Turritella Shell
Catia Parametrically model a Turritella Shell
(OP)
Hi All,
I've been reading through a lot of the posts on involutes and logarithmic spirals. My end goal is to create a model very similar to this: http://www.mat.uc.pt/~picado/conchas/eng/exemplos3... example of a turritella shell in Catia. I've successfully created a macro to run points and a spline for the center log spiral of the shell. I've been using the multi-section surface command to swipe along the log helix but get a lot of errors about cusps and surfaces when attempting to change the profiles used for the multi-section surface. Any help/tips are greatly appreciated.
