Hi Roger, are these part of some larger structure?

Usually for something similar to this you will be better off building a larger surface with a simple 4-sided outline similar to this:



And then trim that regular surface to produce the irregular edges:




That's instead of trying to build a surface through the irregular curve layout directly like you are trying to do.


If you can't build a larger initial surface and trim it, then you would probably need what is called an "N-sided patch" tool which tries to fit a surface through a set of curves. MoI does not have a tool for that currently, you would need to use Rhino for that particular one, but also it can be a bit hit or miss anyway. If it is possible to build a simple surface and then trim it that is usually better.
