i have a problem with zebra analysis and a question about match surface:
Problem with zebra analysis
In zebra analysis usually i have problem to distinguish curvature(G2) from tangency(G1) as you see in the pictures
What should i do?
Match surface question
As you see in the picture :
I want to match surface number 1 with surface number :
At first i match surfaces 1&2(G2)then if i want to match surfaces 1&3(G1) my match between 1&2 surely destroy ? or have change type of continuity (for example G2 transform to G1)?
