Blender is a great program for what it is but the documentation isn’t always as clear as it could be.
I hadn’t tried to skin a surface before and when I tried these instructions in the 2.6 wiki I just couldn’t get it working and I was gong to ask about it here when I discovered what the problem was. The wiki tutorial doesn’t seem to mention that you need to join the curves into one object before using F.
So , in case anyone else spends half an hour faffing about wondering how to get it working here are some notes from me on how to do this skinning of curves. I hope this is helpful to someone as I found the Wiki less than clear.
Wiki - Tutorial
The tutorial in the Blender Wiki leaves out a key step ( unless I missed it!)
- In Object Mode - Add a nurbs curve ( or circle)
- Use this first curve ( or circle ) to create the most complex part of the shape profile.
This will likely require subdivides to get extra control points.
To do this go into Edit mode a press W > Sudivide. Repeat as many times as needed
to get required level of detail when editing the shape.
- Once most complex part of the profile is shaped use Alt-D to create a copy and move it as required along the planned
- Edit that next shape as required BUT DO NOT change number of control points ( Do NOT further subdivide)
- Repeat from step 5 until all shapes along the skinned profile have been created.
- select all shapes that will form the skinned profile.
9) Join these objects into one object. ( Ctrl -J )
- in EDIT mode press F for fill.
- This should skin the joined curves…
- The key issues are - must be Nurbs surface (curve or circle), Each curve must have the same number of control points and the curves must be joined into one object before trying to use F - fill.
I couldn’t find any way to get it to work without joining the curves ( Ctrl-J in 2.70 )
