Easy Geodesic spheres in sketchup

- Here's a quick way to build geodesic spheres and domes using sketchup. I've just started using sketchup, so you don't need to be an expert to follow this tutorial. You'll be making your own geodesic spheres in no time.
Thanks Paul. I learnt a few things. In return, I have a tip - after rotating the four components once, just type in "*4" enter and your dome will be complete.
hi Paul,
I've been looking to work easily and efficiently with spheres domes and polyhedrons in general for quite some time now.
I thought Sketchup was not up to the task: you proved me wrong!
great tutorial, I love it
thanks a lot
I've been trying to figure out how to remodel a piece of jewelry I have. I thought - oh, this shape should be easy peasy in CAD. Boy was I wrong! I think it's probably a 6v or 9v faceted sphere. I've been scouring the internet for a good tutorial and finally I think yours will help me! Thanks very much for a great tutorial
for someone guesstimating joint angles of equilateral hexagonal orbs.. holy arc angles, this be from the vaults of wise'dome! ..congruent to ol' brick masons fix centering radius rope arcing layout domes in digital.. appreciations a bunch! the icosahedron tut was also dead square! burnt some fuses in the mem'brain tryna 'freehand/head' model it point perfect..
You sir, are most likely a genius.
This is awesome, thank you very much!
genius!!!!!!! best tut on geodesic spheres ever!
Hi Paul, any chance you could do a vid on a 6v dome in sketchup ? I would really love that !
Thanks, get it, well explained 👍🤓🙏
I just use the platonic solid phi ratios and then truncate the polyhedrons from there
Hello Mister Robinson. Could you tell please how did you start measure 4V dome. I mean before you start to draw first triangle in the middle and 4 radiuses from the center, please?
Real nice. thanks.
hi, brilliant method!
Hi that is a great tutorial. Thanks. I started following and saw your video. What are you using to cover your geodesic dome? Is each triangle covered individually and if not what are you using to cover it and how did you stretch it so well? Would be interesting to see a video how you covered it. And HOW you can climb it as you did with that one rope?
TYPE 5X TO ARRAY
Did I miss it? When doing the 4v dome, how do you know the height of the centre triangle is 102?
Hey, Paul. I sent you an email recently but I'm not sure if you got it. My main question is about dihedral angles. I'm not sure if I am measuring them improperly but when I modeled the struts of my panels they seemed to be different for each panel. How does one reconcile the dihedral angles (what the struts are ripped to) to be all the same?
Designing a new house right now and this has been my major hurdle.
Thanks!
and maybe a link to the sketchup file you've created in this tutorial as well so if our results differ, we can compare?
+ Paul Roinson
how can i get dome in 0:00 sec ? Thank you very much
Hi Paul, thanks for your helpful tutorial. I've understood very well how to construct the sphere, but the thing is that when I double click the original component, the changes will not be copied automatically in the constructed sphere I made and I can't see the complete sphere while doing the changes at the original component. Do you have an idea why this is so?
Losego Rachele - Sounds like you didn't create the component, or you didn't copy from the component once you created it.
Does it have to be an equilateral triangle? I could not make a proper triangle face to start. when i rotate and copy the sides doesnt unite
Burak Ünver - initially yes. Because you start with a platonic solid.
can you please put the link you downloaded the icosahedron from?
can we export file from sketch up to ansys 15?
I have tried many times to follow your tutorial, but it fails. Every time I need to copy a triangle gets it wrong, it does not turn into a ball, but is flat. What am I doing wrong?
Tom Mørk Yes I think I know what's happening, When you click on the corner to copy rotate you need to hold the click and slide the pointer to the center of the sphere, this makes sketchup rotate around the axis from corner of triangle to sphere center instead of flat with the face. Let me know if this works for you.
Paul Roinson It succeeded, thanks for the help
This rotate-and-copy move you're doing early on with the first triangle component - I've been trying for days, everything I can think of, watched a good number of tutorials on inferencing, watched a number of your videos and seen other examples of you performing this action... but for the life of me, I can't get it to pull the new copy to a new plane while still sharing an edge.
I've exhausted every avenue I could think of before resigning to bother you for an answer.
I would readily accept that the fault is mine, that my inexperience with this software has me blind to some specific, perhaps trivial move of the camera or click of the mouse. But I also see the possibility that my issue is a limitation of the version of SU I'm using (SU'08 - for supposed stability of SketchyPhysics). Could it be the case that the old, non-pro version I'm using is simply unable to make the inferences needed to make this happen? No matter what I do, even duplicating what I see you doing, and every combination of things close to what you're doing, my copy won't come off the plane of that face and share an edge.
If it helps to know, I'll describe what I believe you're doing - maybe you'll identify where I've gone wrong by comparison to what you actually do while performing this action.
With the rotate tool ready, you select a corner as the point of rotation - corner selection appears to be arbitrary. I can hear when you click your mouse to set that point, but I'm unable to determine if at some point you press and hold the shift key to inference lock that corner. I've successfully inferenced the polygon's center point, which is the next step you seem to take, with inference locked and without - so I'm unsure what to make of that. Once the corner is set and the center is inferenced by hovering the cursor there for a moment, a corner other than the one set to rotate is selected, and with a second mouse-click, the copy is initiated and pulls out of its parent component. A third click sets it in place and finishes the operation.
That's pretty close to it, yeah? What am I missing?
I'd be _very_ grateful for any time you're willing to spend in helping me to resolve this (terribly frustrating) malfunction of mine. Thank you..
Nevermind, I figured it out. Of course that would happen right after I finally break down, swallow my pride and ask for help. Of course I have to write a long comment first, to discover what I was missing like, 20 minutes later.
If God exists, I'm certain his name is Murphy..
OK I hope I can help, my best guess is this... You have everything correct, so you can rotate copy a selected object, yes? it's just the "axle" about which you are struggling. Here's exactly what I do - Select object - select rotate tool - Click a corner from which you want to rotate (Ok the next bit is very important!) Do not click and release, you must hold the click down, then slide your curser down to the bottom of the line you want to use as an axle, then release the click. Use alt to make a copy and rotate as usual. The rotate tool will snap to any face so if you can make a face that is perpendicular to the rotational plane then you could do that, but I think clicking one end of a line then releasing when you have hovered over the other end is better. Give it a go and if you still have bother I'll revive the video and make a step by step easy to follow video for you. I an assuming that you can do this in SU08 the oldest version I have is SU15.
@@Geo-Dome thanks for your reply and explanation Paul - I appreciate it.
I ended up figuring it out shortly after I first posted. Before that, I just wasn't making the connection between your "click and slide" and holding the mouse button down through the intended axis to inference the center point in such a specific way. Seems a bit counterintuitive to me, but I dunno.
Anyway, thanks again for sharing so much of what you've learned - it's helped out quite a lot of us, I'm sure..
Is the beginning shape (that 1 section of the icosahedron) a tetrahedron?
+Megan Weber No but it is close, if you had a radius of 10,000mm the equilateral triangle would have sides of 10515mm. Hope that helps.
Thanks.
Is there a link to the original polyhedron you started with?
Jess White Water Queen - If you can't find one to download he also made a video of how to make it from scratch. ua-cam.com/video/bR2BL2C8fvo/v-deo.html
there is: go to the 3D Warehouse and search for "geodesic tutorial"
yes, look for Taff Gochs "geodesic tutorial" in Sketchup's 3D Warehouse
