Bill Tillman Posted November 14, 2020 Posted November 14, 2020 (edited) I've always been intrigued by dome geometry. I think I have this model in somewhat decent shape. What I want to do is clad the interior of it with .093" aluminum sheet. Could use some help from sheet metal people if I'm on the right track here. I'm thinking I will need to get the arc length of inside of the rafters to get the flat dimension and the dimension across the chord at the bottom. My concerns are when they roll this panel will there be any allowances I should be aware of. Canopy Dome.dwg Edited November 14, 2020 by Bill Tillman Quote
SEANT Posted November 15, 2020 Posted November 15, 2020 (edited) And actual sphere section would be a compound (double bend) surface which would be much harder to fabricate. Conceivably, the intension is to use a developable surface where the curvature is limited to just one direction. If that is true then this would be closer to what is required. No allowance has been made for clearance. DomeSect_Developable.dwg Edited November 15, 2020 by SEANT Quote
Bill Tillman Posted November 15, 2020 Author Posted November 15, 2020 Thanks Seant, Those are exactly my thoughts. The architect has now moved the sheathing to the exterior side of the dome. Again no problem if we only roll the panel in the one direction and let the bottom stay segmented. Quote
