Anyone know how to cut out a flat plate and then curve it?

[odomarchitects1810]

I have a concept for a monument competition of an 8' diam globe made of stainless steel bars at the longititude and latitude lines. (See attached image.) I want to create a flat extrusion that is a cutout of continents and then bend it to follow the curve of the earth. It will be far easier to make in reality than it is for me (at least) to figure out how to make a 3D Revit image of the continents attached to the globe. Any help or suggestions will be greatly appreciated.

You wont be able to model a flat plate and then curve it. You will have to model the extrusions oF the continents in such a way that they extend into the globe, and then use a revolved void to cut the extrusion off at the surface.

Off the top of my head, why don't you make the continents very thick and then use a sweeping void to cut away the pieces to create the curve. Does that make sense?

EDIT - MAYBE SCOTT AND I ARE SAYING THE SAME THING?

[Scott D Davis]

Yeah, after making the model-image above, and re-reading the request, the 'curved' continent pieces would be made as shown, except yhe 'solid' globe above would also be a void. You would have two void-revolves, both cutting the solid extrusion of the shape of the continent.

Probably won't help, but here's an import from 3dcafe 3dsmax file. Can't answer your question.- ain't smart enough....

Having fun experimenting with Revolved solids and voids in Revit. Here's an example of a way to tackle the 'globe' problem above, but the hard part will be extruding the shapes of the continents in the right direction!

Each "disk" in this image is actually a small dome shape, not just a flat disk.

I would do them one at a time.

The I would do it is

1. the plates shown in your examples are curved on both axis.

Decised whether you want to do this as it would be very difficult to "bend", it would be rather poured into a mould to take that shape.

if you decide that a flat plate would be just fine (curved in 1 direction) then I would generate what we used to call in my tech school days a development piece which is basically a flattened version of your final product. to do this I think you need to generate different radius as it is a sphere.

Let me know if you want to go down this line and I would be happy to assisit help you out.

Post the profile of North America and I will take a shot.

Here's British Columbia in the format you're looking for -- to save Chris' bandwidth, I've posted it on the company website:

(And sorry to the poor sots on Vancouver Island and the Queen Charlottes whose landforms were not modelled during this exercise)

That is exactly what I was thinking, thanks Wes.

Wes,

I made the Island dwellers happy for you. Only took a minute, now that Revit allows the TAB key to select a chain of underlying DWG lines.

Scott, discovered that tip about about using the TAB key to select dwg line's last night. Saved me load's of time, I was going to post it in the tips section I is was that excited. (but I forgot - late night)

We Island dwellers thank you! (poor sots, indeed!) :)

I didn't notice this til now, but BC looks like a fat version of California, after the "Big One", when a monster earthquake splits part of California off into the Pacific along the San Andreas.

This forum is waaaaay too funny.

That's great, Scott... now all the Revit users in Skidegate won't feel snubbed! :lol:

Just a few weeks away. Anyone out there taking that seriously?
