For me it depends on the size of the surface involved as well as the point density.
I have used the UV scan method and it works ok, but if you don't use it often, it takes a while to figure it out and lots of refining to get exactly what you want.
If it's just a single surface and one part (instead of a family of parts) I do it manually with a grid overlaid with the CAD graphics utilities.
I'm not at a PCD-capable machine right now, so I can't get this exact, but I'll give it a go.
On the toolbar is an icon that gets you to a window that allows you to create a 3-D grid.
I just set this to the density I want, say, .25" X .25" and then manually add autovector points at the grid intersections.
As I said, depending on the surface area, this can go pretty fast and is easily edited.
Think about it.
This can take only a few minutes, and instead of spending a bunch of time getting the scan "just right" you just point and click a bunch of points and yer done.
If you need the spacing exact you will need to use the scan method.
