The curve tool we use most is the Edit Point Curve.
00:06
So I'm going to switch to a side view and then simply click a start point
00:11
and an end point.
00:12
And then do a Pick Nothing,
00:14
Pick Control Vertex,
00:16
and then use move to start shaping the curve.
00:19
And I'm using the left mouse button to just click and drag.
00:24
And if I want an extra CV,
00:26
I would typically stick with a single span for smoothness
00:30
and instead increase the degree by one
00:33
and then hit accept.
00:35
And then Pick Nothing,
00:37
Pick CV, move again,
00:39
and keep going until I'm happy with the shape.
00:46
For this straight line, I'll use the Edit Point Curve tool again
00:50
and hold down Ctrl to do a point snap
00:53
and then just click and drag to the other end.
00:56
And I don't need these middle CVs,
00:57
so I'll reduce the degree down to one and hit accept again.
01:03
Now I'm going to need to move these curves out to the side.
01:06
So I'm gonna use a two screen layout so that I see the side and top views together.
01:13
And first, I'll pick the curves and do a move using the right mouse to move only in Y.
01:19
And you can see that I'm not losing any of the XZ shape I created in this view.
01:25
So then I can use Pick CV and do the same for the CVs to get the 3D shape.
01:31
But you don't have to use these 2D views,
01:33
you can always use the XYZ mouse directions in the perspective view.
01:40
So now I can build from these curves
01:42
and I'll start by double-clicking on the MS draft surface as an example.
01:47
And I'll select the curves
01:49
and then choose the direction and give it some length
01:53
and then click on build.
01:55
And I'll just shade that.
01:58
I can modify the direction or add some crown and
02:02
use the space bar as a shortcut for Update.
02:05
But if I delete that,
02:06
this time I can create the subdivision extrusion.
02:10
And again, I'll open the settings and select the curves,
02:14
and I can use the manipulator to just bring this out.
02:19
And if I use the box shading,
02:20
you can see here that my curve is recalculated into segments
02:25
and I can just adjust it to the complexity I need.
02:29
And then keep using the space bar for Extrude Again
02:32
and start to build up the sub-d.
