Creating a globe (sphere)

Anonymous — Wed, 24 May 2023 17:02:02 GMT

Hi guys,
For my graduation project I'd like to create a hollow globe (i.e. http://www.featurepics.com/FI/Thumb300/20080526/Metal-Globe-746072.jpg) as an entrance for my complex.

For now I just used the Shell Tool to create a sphere with a thickness, but I'd like to see more detail in the model with the open and closed parts (oceans are open, land is closed = metal panels).

Even a simple globe would be fine so I can upgrade it for rendering in photoshop, but I simply have no idea how I can get the world in this sphere with something like the solid element operator.

Does someone have a good idea how to create this? Thanks!

If you create a Shell, it is possible to place any number of Holes into it. YOu can define the Hole contour and it will cut it in the Shell element. The Hole's cutting body will be an extruded body and it will perform a "Subtract" Solid Element Operation on the body of the Shell.

These Holes can be tricky to define in the case of a Sphere shape because you would have to define, e.g. the shape of Africa as projected onto a planar surface from the curved surface of the Globe. I hope this makes sense. I don't know from where you can obtain that geometry to define the contour of the Shell Holes.

Try next...

Go to Google warehouse and find there a globe.
Import it in archicad and create morph from it.
Scale it up to needed size, erase oceans and seas and any other stuff on globe that you don't need.

Window on some continent:
create wall with window, then create morph from window.
Move it to right place and scale it as needed.
Edit morphs as need to accomplish needed look

Thats the fastest and (for me) easiest way

I hope this helps !

Please don't forget New Zealand. Looks like they did in your image.

Thank you for the replies.

I liked the Google warehouse idea, so I tried it since manually drawing continents and SEO them out of the shell is way too much work for now.

Unfortunately after I import the file the object is fine, but when I convert it to a morph it changes...
I have added screenshots so you can see what I mean.

ArchiCAD texture mapping is very limited. As you saw, an imported object will get the UV mapping correctly, but converting or editing will break the map.

What you're showing though is a simple texture mapped globe, but your original post seemed to indicate that you were looking for a more detailed model that massed continents and left the oceans empty? Just do a Google search. I think these are more along the lines of what you're looking for?

It's correct that it's a more complex shape than a simple globe. But I didn't know how to manage to make it.
But the idea of just searching for a modelled globe is indeed a good one. I feel ashamed that I didn't think of that, haha. Thanks!

I can probably edit extra's around it, so it looks like a metal construction

Unfortunately there are no good free ones that I can actually load into archicad. I get an error with some of the images after 10 min loading...

So I'll just photoshop it into the section/elevation and renders
