Rebuilding a NURBS surface to optimize its control vertices (CVs)

- The last object that we need to model…in this entire project is the seat.…Let's create a new layer called 3D seat.…Turn it on, set it current, and give it a color.…This time, I'll choose magenta.…We have two different drawings of the seat.…The plan view here, which is broken…into two pieces, and the elevation.…You can see that better if I orbit.…These are both planar sketches.…I'm going to convert the plan drawing into a surface.…

Type j for join and join these two splines together,…making a closed loop.…Then choose surface, planar.…Press the down arrow to access the object option.…Select this object and press enter.…So now we have the seat surface.…In order to shape the seat, we're going to…convert it into NURBS.…So let's choose convert to NURBS right here.…NURBS stands for non-uniform rational basis spline.…

And it's a kind of math.…This mathematical representation…gives us different editing capabilities.…I'm going to convert this surface into NURBS.…It looks the same though.…They are very subtle differences.…
