Also, if a Administrator/Moderator would be so kind, please remove the earlier versions (uploads/244286/Ellipsoid.zip and . . . ./Ellipsoid2.zip).  I, and any future members that may accidentally download those versions, would be grateful.  I would do the housekeeping myself but I haven't found any mechanism for editing my previous posts.

Kent, that is an interesting methodology.  Depending on the use it may be more representative of the projects final outcome.  And, without a doubt, ACADVer/AutoLisp compatibility is king.

 

Thank you back.  One nice thing about that routine is that it's not version-dependent as the .dll things appear to be, so people with any version of AutoCAD can build elliptical Domes with it.  [That is, unless you go way back to an early enough version that the Ellipse command made only a Polyline approximation, in which case I think it should still work but wouldn't be as accurate in shape; or maybe some very old versions don't have all the needed 3D commands.]  In fact, it was worked out in a version from before NETLOAD -- I did it partly because in the AutoCAD I have here [2004], I don't have the possibility of trying those other routines.

 

Ok, if that's the case, then it works perfectly. Thanks again for your help with this. Greatly appreciated!

 

 

Yes, that is the way the routine works.  The routine is very basic.  You would have to adjust dimensions, Height specifically, to accommodate the necessary slice.

I'll try to get one of the Autodesk DevTechs to take a peek.  I'll post back if I hear anything. 

 

Actually, that is a debugging remnant .  the Solid3Ds are slightly more "solid" than I implied above. 

 

Othe than that, it worked great.

I can certainly confirm something amiss.  The routine as posted earlier works on my desktop, but not on the laptop.  I've isolated the problem to the Solid3D.Slice(surface As Autodesk.AutoCAD.DatabaseServices.Surface) call, but I haven't found out why it fails intermittently.  AutoCAD may be haunted.

 

I did modify the procedure a bit, and it now works on both of my machines.  In case anyone's up for another go, I'll post the modified code.  Due to a couple of reasons, all valid no doubt, posts from a "Newbie" containing attachments require moderator involvement.  I'll attach the new code to a post directly following this one.
