Extending curves and surfaces

“

- Let's take a look at how we can extend or extrapolate entities in Alias. So in this case here, I've got some very simple entities. I've got a single Bézier curve here. I've got a NURBS curve here. And see the indicator here, that's telling you that it's five span. And I've got another entity down here, which is a problematic entity. And we're gonna take a look at why this would be causing problems during the extrapolation process. So let's go to Object > Edit > Extend and I'm gonna do a reset on this. So we're going to use Extrapolate. We're gonna merge and we're gonna go by distance. So let's go with the first entity. So with Extrapolate and Merge, you notice that it actually redistributes the control points along the extrapolation. And as I release, it's actually merged that extrapolation back into the basic curve. Now if I do this on the NURBS curve, you'll notice that the extrapolation only occurs on the last segment. In other words, it goes back to this edit point, to the end…
