Thanks Michael, now I understand it, and now the Network tool works for me! :-)

Yes, I did read the documentation before posting as suggested by Frency Pilou. I also searched the MoI forums and tried to google an easy explanation on "Coons Patch" but I just didn't get it, until now... Sorry.

The Network tool seems fairly powerful actually. It gives me some more freedom to sculpt but can I add control points (including new corners) after the surface has been created?

Hi Hbasm,

Once you have created the surface from the network then all curves that created the surface will be left and show. If you then select all the origin curves (which are by default left as shown/selected after creation of surface) you can select "show pts" then "add pt", that will allow you to add control points to the various control curves which will then affect the surface.

Thanks Manz, that ... kind of works... I'm a bit confused about the relationship between curve-points and surface-points (why do we need both?) but I'll experiment a little and see where it leads me.

Until next time,
Hbasm

Well, I mean basically surfaces and curves both have 3D points in them as part of their structure... So it is possible to edit this part of the structure of these objects.

MoI's toolset is more focused on curve editing for now though, for example it has a way to insert or delete points from curves but not surfaces. But you can turn on the points for surfaces and move them around.

If you have drawn profile curves to create a surface by something like Network, it can be more manageable to use the History update mechanism which allows you to edit your curves (including adding or removing points) and then has the surface automatically recalculated using that command again. That lets you control the result by just those profile curves that you picked for running the command, that is usually a smaller amount of things to manage than the full set of points on the resulting surface.

For certain kinds of models it can work well to modify surface points instead, and it is possible to create a surface like a sphere directly and then turn points and modify them without ever using a profile curve at all. For instance lyes used that for creating this gas tank shape here: http://moi3d.com/gallery/viewitem.php?id=50

So that can come in handy for certain kinds of things, but generally it is not a focus for MoI's toolset right now though.
