Grid on curved surfaces

[ALHABI]

Hi,

I am working on creating a building shell that is elliptical. i managed to draw it 3d through lofting. now i am trying to have a hexagonal grid on it so i can draw hexagonal large structural ribs and then in between the ribs hexagonal glass grid. Any help?

i hope u can see the attached images.

Imprint might be your key.

Are you using as vanilla AutoCAD or as AutoCAD Architectural?

I am using autocad architectural 2010

I think there is another forum for AutoCAD Architectural questions.

thanks I will ask.... but i don't think i will find the answers there...

best regards

Imprint or any of the other Intersection methods should be able to return useful Geometry. It is tough to determine the parameters from the sketch in post #1 – here is a general model derived via Surface/Solid Intersect, Thicken, and ProjectGeometry.

 

The model lacks fine tuning but hopefully demonstrates some of the possibilities with vanilla AutoCAD. Architecture may offer even more methods.

dear gentlemen,

thanks for the advice. i have worked by doing the hexagonal grid in plan then extruded it then subtracted the glass shell (same elliptical shell with thin depth) to give the space frame shape, and the big hexagonal grid to give the big concrete rib shape. i hope it is convening. the issue will be how to do the engineering part...
