CREATING 1'0" 3-D DOMES

[Andrew Mac]

i AM SOMEWHAT NEW TO THE 3-D WORLD. i AM TRYING TO CREAT A 1'0" THICK HOLLOW HALF CIRCLE, MEASURING 10'0" IN HEIGHT, AND 20'0" RADIUS, ESSENTIALLY A DOME. CANSOMEONE HELP ME GET STARTED IN THE RIGHT DIRECTION? THANKS

"Essentially a Dome.."

If you just require a dome shell then you can use the Sphere Object:

"...Applications/VectorWorks%2011.5.1/Plug-Ins/Sphere Object.vso"

But if you need to design to construct other than a 'perfect mono shell' then specify the type class & frequency required.

[Biplab]

Just create a hemisphere of radius 25'. Then shell it using Shell Solid Tool using a thickness of 1' and selecting the bottom cap (be careful to select the bottom cap as the selection of the spherical face and botom cap looks the same). You can also create another hemisphere of 24' and subtract from the larger hemisphere. Then go to the front view or some such view where you see the elevation of the hemisphere and split the hemisphere using a line 10' below the topmost point of the hemisphere - you may need to construct a locus or a line for this step.

Or Join & Compose the two radius arcs & Revolve with Rail to create individual angular segments or the entire shell.

[islandmon]

You only have to create a segment of the Dome as a symbol:
