Models can be a great way to test building structures and if your thinking of constructing a geodesic dome building a paper model first is a great way to run through the construction process. First download the geodesic paper model plans then follow these simple instructions to assemble your dome model:
After downloading and printing the dome plans, (you will need to print 8 copies to have enough panels for your dome) cut each triangle at the red dotted line. You should have 45 panel ‘A’ triangles and 30 panel ’B’ triangles.
Now fold all the edges along the black lines to form tabs on each side, these will be used to glue the panels together.
Glue together the panel ‘A’ triangles to form 5 hexagons and 5 half hexagons. Glue the remaining panel ‘B’ triangles to form 6 pentagons
Now glue five pentagons to the five half hexagons alternately, (see diagram below) then glue the five hexagons in the space between each pentagon and finally place the last pentagon in the top.
You should now have a finished dome like the diagram below, don’t forget to glue your model to a stiff peace of card. I’ve drawn a red line to show the glue lines between pentagon and hexagon panels.

You forgot to mention that this model is a 3/8 dome if you add another 30 triangles (the ones that make hexagons) around the base you can turn the model into a 5/8 3v dome.
Jonny Spence and Graeme Brown Third Year Architecture Students built a paper dome model as part of a city center design project.
Great job Guys!
Where do the "eighths" come from?
It`s a 3v 4/9 and with the extra bottom row .. a 3v 5/9 :)
the mixup with eights and nines in third frequency are very common. Many of my educated clients (am manufacturing domes for living) are pointing out the fact that there are 9 segments. The common cause of this is the UK and US system employing "halves" to state the size, volume etc. Would it soud right to pronounce "4/9th of an inch"? it's just comfortable to use quarters, eights etc...
and if we are going to calculate the real ratio, we'll end up with 2/5 and 3/5 respectively (talking of a sphere)or 0.4 and 0.6 in Europe... Never the less the dome remains itself, no matter how you call it. and the only relevant information is the tensegrity!
THANK YOU SO MUCH!!! I built the dome and got an A+ on my project!!!!!!!!!!! YAY!!!!!
i copied the template in word, then enlarged it onto A1 card and its massive!also got an A in a graphics project, my model looked like a giant compaired to the others =)
this method is far too complicated. too many sections involved, although it can be done, there are more simpler ways of constructing a dome. the whole point of the geodesic dome is that its easy to construct, this method will get you thinking other wise.
Love the design - can you tell me the finished diameter please?
Love the idea alot am looking for a project to do this summer was thinking of a dome shed. Still trying to figure out all the angles anyone got any hints/help of places to go to get more info of the topic?
I figured why build PART of this when I can just build the WHOLE SPHERE! I think it turned out pretty sweet!
That looks great!
I'm going to try and build a dome as a piece for my twain set in the basement...
is very nice for residential complex.
Hi .. Is it possible to simply add half hexagons and full pentagons to the base run to make a bigger model? Thanks
I want to build this geodesic dome and show in this site.
Thanks this page helped lots with my project on the domes
the only way this could have been easier is if it made itself!
Thank you so much for this great info!
I used these triangle to create an image of a complete dome where as many triangles as possible were connected from the beginning, to minimize the cutting and glueing: troja.ath.cx/~zond/images/dome.svg
Thanks for your model! The triangles themselves will help me construct a geodesic dome out of gingerbread! :D
@Martin, thanks for the svg file. really cut down my time to build the dome using modelling board. :)
One problem I foresee is how to attach the plastic or plastic-type membrane to the struts/triangles. Can you suggest the recommend methods please?
I just wanted to let you know that this project was a HUGE success in my classroom. We had three groups construct their own domes (I mixed the card stock colors so all the domes would be multicolored and all the pieces would be easier to discern). We then went on to create a playground size dome from rolled paper struts (butcher paper rolled around broom sticks, paper punch, machine screws, washers and nuts. The students were able to climb inside of the huge dome and have their pictures taken for the yearbook. HUGE SUCCESS!
I am re-creating the lesson plan for an Applied Math conference that I'm attending tomorrow. Thanks again.
This activity worked very well in the Middle School curriculum. Thank you for sharing!
Where can I download the net?
Thank you so much from us both! Needed a dome for our project of the Hagia Sophia! Worked great!! Thanks again!!
