Hello Rhino Gurus!
I am trying to understand the whether / how to manually position surface control points to achieve G1 continuity.
So, for curves, tangency is achieved by aligning the 2 last points of a curve as seen in level 2 training.
What about for surfaces ? Aside from the automatic tools like ‘Match Surfaces’ and the manual ctr ptsG1 Cont Simple Example.3dm (487.9 KB) editing tools (Drag, UVN etc) is there a geometric construction that allows to position the second to last row of UV points (points 4 to 7 in the image below) so as to achieve G1.
What are the degrees of freedom for these points without breaking continuity (infered) – not refering to endbulge (automatic tool) but more to “these points can move in a plane obtained from …” for ex. ?
Enclosed an image and a 3dm model of a simple case made up of 2 surfaces Degree 3/ 4 Control points. (U&V)
