3ds max Spline Modeling Creating a freehand spline So we have granularity and threshold. And each time you click and drag you’ll create another curve. So I can click and drag with the default settings and then enable the switch to show the knots, and we can see all the control vertices. We can get in closer there.
We can even go over to the other views. Maybe right click in the top view and press the z key to zoom. I can create another freehand line, maybe in the top view this time, or change the settings over here, granularity and threshold. Maybe increase the granularity and try again and see how that works. So with higher granularity we’re getting fewer samples as we draw each stroke.
