Hi Michael
Here is the screen shot of my problem with Network

Hi FED, it helps a lot if you can please post the .3dm model file with the curves in it instead of only a screenshot.

That way I can do things like examine where the endpoints of your curves are and zoom around and inspect it from various angles and other stuff like that which isn't possible to do with a screenshot.

From your screenshot my best guess is that it looks like some of the curves in one direction are closed and some are open - all of the curves in one of the network directions should be the same with regard to open or closed, not a mix.

Thanks, - Michael

Hi Michael-
Thanks for your patience and help!
I am a new at 3D modeling and MOI, but I am trying hard to learn this great program!!!
I have attached my file.

Hi FED, so to make a network you would need to reconfigure your curves by cutting the bottom one in half using Edit > Trim so you've got pieces like this:



Then you'll be able to have 3 curves in this direction:



And then in the other direction you'd need to use Edit > Separate and delete the bottom pieces so you had the other curves set up like this:



Then you would be able to use Network, see attached file. But it will be difficult to avoid a kind of pinching effect at the "poles" in such a configuration.

For dome shapes rail revolve can be better, although you will give up some of the control over the sloping of the sides. But to use rail revolve, you'd select this for the profile curve:



Then run Construct > Revolve > Rail revolve, then pick the bottom closed ellipse as the rail, and then pick the revolve axis here:





That will make the pole where the surface pinches together to a single point to be at the top and to have nice shaping there.

Hi Michael-
Thank you sooooo much!
I am going try it out!
Really appreciate your time and help!!!
