Experienced user of surface modelling in parametrics, reasonably new/returning to Rhino
Observations and suggestions on the following gratefully recieved;
Because of the complexity of my usual models I prefer to build symmetrical to a mid plane and then mirror when finished.
To ensure my curves are normal to my symmetry plane I’m using grid snap or ortho to ensure the end control vector is perpendicular at the connection point to the sym plane.
I build my curves on the symmetry plane and extrude them to the mirror side to give me a reference to match my surface edges to, ensuring my surface boundary conditions are normal at the sym plane.
Setting curves or boundaries ‘normal’ doesn’t seem to be in the Rhino toolbox? so I presume the philosophy is to have a reference - curve or surface - for G1/2?
