Thank you! Everything I share in my videos is learned the hard way by plenty of trials and errors, until I figure out a practical solution.

Thank you! :)

@@AutomotiveCNC you mind sharing your rhino layout? (interface)

@@masamiakita993 , mission complete :) discourse.mcneel.com/t/back-up-topic-share-your-rhino-options-and-toolbar-layouts/185419

@@AutomotiveCNC ur a legend

Thank you for the appreciation! More short tutorials like this one are in the making soon.

These are custom viewport modes which you can download from this topic: discourse.mcneel.com/t/share-your-custom-viewport-modes-here/151321

That would create a curve approximation with too many control points. A surface built from a pulled curve is also inaccurate and needs extra matching, which adds even more control points. The idea of the basic curve with 4 control points which I used is to create a simple surface with fewer control points, then match its left edge over the untrimmed target surface.

​@@AutomotiveCNC In pull command, there is a loose option. If you change "loose" option to yes, it will not change the degree or point counts of curve. It will try to best match it to surface without changing curve.

@@akchemaceshwa , I'm aware of this, but using a manually adjusted basic curve is the better way to build the surface.

@@AutomotiveCNC That is how it works. But matching curve, surfaces to achieve desired continuity is also the part of the process.

@@akchemaceshwa , pulling a curve on surface uses the normal direction of the latter, which is a limiting factor. Manually adjusted curve is the better option, because the user has a full control over the shape, with no imitations.
