In this next example, I've built some simple block shapes using NURBS surfaces
00:07
as these give me very clean reflections.
00:10
So I'm going to use the side surfaces
00:13
and with Retopo,
00:14
I'm going to select the surfaces as targets
00:17
and then Next and then Go.
00:21
And a slightly different way of working is
00:23
to just start by specifying the whole shape
00:26
and then creating a large face
00:29
and then I'll do another one.
00:31
And then I can just use Insert using Shift
00:35
to add divisions
00:36
in particular where I've got features I want to capture.
00:40
And because we had smooth target geometry,
00:43
the subdivision has got pretty good highlights
00:46
which gives me a good starting point to develop the side of the vehicle.
00:51
And with the roof,
00:52
I'll use the NURBS surfaces and an existing SubD
00:56
which doesn't fit the roof shape yet.
00:59
So if I do
00:60
retopo, I'll pick the target surfaces as before.
01:02
But this time, I'll answer the second prompt by selecting the SubD
01:06
and then hit Go.
01:09
Now this doesn't automatically snap to the target surfaces
01:12
until I pick and move a vertex.
01:16
And I can use the Relax tool with the right mouse button as
01:19
a quick way to get all of the vertices attached onto that target.
01:27
And then if I don't use any target geometry, so I'll just hit Next and Go,
01:33
I can create directly in a view plane.
01:36
So I'll choose the side view
01:38
and then draw freely with all of the
01:40
Retopo tools.
01:42
And there's no great advantage to this, but some users just like the Retopo
01:46
workflow and prefer it to starting with curves or primitives.
01:53
Now, this only creates a flat SubD in that view plane.
01:56
So I would delete the construction history so that
01:59
the vertices no longer snap back to the plane
02:02
and then move it and edit it with the normal
02:04
SubD tools to start building up this cant rail.
