Sure thing.  Thanks for sharing your design too.

Another method to create the surface would be to use EDGESURF.  You need four edges though so take the piece of an ellipse that is the longest of the three and break it.  Once you've run EDGESURF you can then run the Mesh-to-Solid lisp found here at the CADforum to generate a solid.

What aren't you getting?

If you could do the 3D model you uploaded to this site then you can do this.

You're going to be working with just one quarter of the ellipse in plan, front and right views.  You're going to loft the two vertical sections of ellipses and specify the horizontal section as the "guide".  That's what will create the surface.  The surface needs to be given a depth.  That's what the Thicken command is for.  Once you have one quarter of the dome completed you mirror it to create half a dome then mirror the half to create the whole dome.  Join all four sections of the dome together using the Union command.  I'm sure you can handle it from there right?

Thank you, very much for all your help. But I'm just not getting it...My lack of experience and my trial-and-error technique to learning has only allowed me so much. I'll keep trying thou. The rat gets the cheese eventually, right?! Have a good one!]]> Mon, 02 Jun 2014 20:27:03 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27289&title=nurbs-api#27289 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27282&title=nurbs-api#27282 Author: John Connor

Create one quarter of the dome using the Loft command.  That will create a surface.  Use the Thicken command next to get the overall thickness.  Then mirror and union the separate pieces to create the entire dome.  Extrude a circle through the dome and Subtract for the hole.  Slice it up as you see fit.

Basically, I think? I've generated shapes before and then I've sliced them using the "Slice" Command.
Then I've used "interference checking" to generate new shapes. Or make new
surfaces that are perfect!? So, how can I generate an ellipse in three directions? Mesh or otherwise, so that I may "SLICE" it every 12" with an 1 1/2" solid? Did I ask that right? BTW, Thank you for your responses!]]> Mon, 02 Jun 2014 19:47:26 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27281&title=nurbs-api#27281 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27280&title=nurbs-api#27280 Author: John Connor

You would slice it using the SLICE command wouldn't you?  Maybe I'm not following you.  Sorry.

OK, I gave it some more thought.  Tell me if I am on the right track.

Basically you want to create an elliptical dome with a thickness of 6.0 units (I based this on your original drawing) then you want to slice it into multiple sections of 1.5 units?

See ellipse block in "New blocks"... instead of creating the rafters one by one for a roof. I wanted to generate the shape and slice it...I couldn't figure out how I could do that.]]> Mon, 02 Jun 2014 18:37:39 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27277&title=nurbs-api#27277 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=10340&PID=27276&title=nurbs-api#27276 Author: John Connor

Yes, you can extrude, loft, sweep and revolve an ellipse.  What are you trying to create?
