Make the original pentagon a component and move a copy out of the way of constructing the dodecahedron as instructed in the video. Go back to the copy of the original pentagon you moved out of the way and extend the edges to make a 5 pointed star with the pentagon in the middle. Voila !!! A stellated dodecahedron to hang on the Christmas tree. You could have done this without making that first copy and just edited any one of the pentagon components but having a copy separate from the model makes editing into a star a whole lot easier. I went on and used the offset tool on the five points and the pentagon to give me a thin inside border, then the pull/push tool to depress all 6 inner faces just a little and coloured these with transparent colours. The result was a fabulous leaded stained glass type construction.
I can't help make some clarifications. If anyone new to SketchUp don't know how to set the polygon tool to draw a 5 sided polygon, just type 5 and press enter right after activating the tool. The number of sides is reset to 6 each time SketchUp starts up but I presume Aaron had already changed it to 5 sides when doing a practice run before recording. Also, if you don't follow what drawing the arc is for, it's because Rotate Tool has no "From Radius" snapping. The arc tool however find the intersection between the arc and edge.
Great catch, Christina! I recorded three videos that morning and I missed pointing that out! And you are right... The polygon tool was set to 5 sided as that was what I recorded when practicing!
Hi, does that center point projection method apply to other shapes? For example if I wanted to draw a soccer ball shape made up of pentagons and hexagons? Is there a way to rotate the parts so the corners snap perfectly? Thanks
To make a soccer ball, you start with an icosahedron and then delete the lines that make up the pentagon sections, leaving the hexagon sections alone. Lots of videos out there to make an icosahedron.
I love Sketchup, but I was alsways wandering what did the devs have in mind that they did not include such basic form tools. Like in many programs you could create such geometry with just 2 clicks using the basic tool.
Very late reply from me, but you're absolutely right. They could add a punch of tools that are just one level above basic tools and guess what?! ...the SketchUp is taken to a totally different level.
Hi, Aaron, when you perform those aiding lines, it's still a math knowledge, I try to use components to snap together, but the snap can not catch accurately, I tried many times, it always misses a tiny bit, could you figure out the reason? my workflow is as this: draw a pentagon as the base, then second pentagon, I make it as component, copied and then place two components sharing the same corner of the base with edge aligned with the base, then I go into a component to rotate the pentagon, theoretically, corner of pentagons should snap together, but there is always a tiny big miss catching on the point, can you explain this?
The only things I know about the geometry of a dodecahedron is that the sides are pentagons, and the tip of the "side" is directly above the middle of a flat pentagon. I honestly could not even tell you WHERE I learned that!
Are you talking about a geodesic dome? I'd love to see Aaron do that, but it can't be done using this method, I don't think. I've seen others do it. Use search on YT to find it.
Click what at @3:31? I cannot get that arc to go against any of the axis directions - driving me nuts! Please help... Instead I just rotated the first pentagon to lock into the red axis, then went from there.
While I appreciate this video, I think there is a direct contradiction between what is said at 1:30 and at 2:10. First we are told that this method of making a dodecahedron will be “without any sort of math or pre-established angles or anything like that” (1:30) and then we are told “I know that when it does rotate up this point will rotate up along an arc directly above the center of this shape” (2:10). If this is NOT a contradiction, then please provide a simple explanation for why you “know” what you say at 2:10. I’ve stared at, drawn models, searched on the web and just can’t figure it out. Someone show me the light!
Not sure if you worked it out but the most likely cause is that you didn't quite hit the top of the guide line when you performed the first rotate. I've played with this method a few times and once I dropped the first one slightly before the tip. Zoom right in the check you are hitting it correctly. If you miss this from the macro level it looks fine but as you progress this error is copied around and ends up creating those small gaps you find when zooming in.
How are you navigating in Sketchup? I do not see you using the orbit or pan tool. I'm guessing you're using the keyboard, but I don't know how. Can you Clarify? It would help a lot.
Hey! Thanks for the reply :) I checked the site, but its a little expensive for me (poor guy studying architecture :P). Is there a software alternative for this (like an extension in the warehouse)? Sorry for the trouble.
OK - color me deficient in grade school geometry, but - WHERE, praytell, did you find the ever-so-crucial tip that the 2nd pentagon had to be rotated until the distal tip aligned with its pre-rotation CENTER???? The teacher is gonna think you CHEATED!
@@AaronMakingStuff Yup, that's precisely what I'm admitting! Started getting "mechanical drawing" in 7th and 8th grade, then on in HS, but if that little detail was EVER mentioned, it has evaporated from MY gray matter COMPLETELY. While that's a theoretical possibility, it remains unlikely. So - yeah - that weren't taught when I goed threw skule. Fortunately, I enjoy learning now even more than I did then, and I (think I) know how to pick good instructors, DON'T I?????
@@palewriter1856 Me too... not sure why I learned to enjoy learning AFTER I left school, but I did. Thank goodness it;s so easy to find learning materials nowadays! Ans, yes, you have exceptional tase in instructors!
A simple "No." would've sufficed. Not only are you misleading, you're overly excited about a mundane answer to a mundane question. That rubs me the wrong way. So I wonder... Can you tell me which version it became one of the native tools?
No intention to mislead or rub you the wrong way. Just trying for a quick, direct answer. Additional Arc Tools were introduced in the 2015 version of SketchUp.
Sorry... See if this helps: Dodecahedron, dodecahedron, dodecahedron, dodecahedron, dodecahedron, dodecahedron... I guess it;s not the same when typed...
I have a new respect for the rotate tool. Here I've been rotating my whole model like a chump.
Make the original pentagon a component and move a copy out of the way of constructing the dodecahedron as instructed in the video.

Hi Christina, I know that you are a Sketchup Master. Could you please tell me the mathematic name of the curve which is used to flip the face up ?
Right on time, for new Christmas dodecorations...Well done Aron, great video...!
Oh, yes!
Yay!
I did it!
Thank you, Aaron!
Very Nice exercise Aron!

Very good explanation, and also very good solution (usefully in every software)
Thank you

That is well done. Bravo!
thank you very much i reallyyy needed this
How did you know that the first fold would go until the vertex met that vertical line from the center?
"I'll be saying it a lot through this video"... [Says it once, five minutes later]
:D
You can have a lot of fun with using components instead of groups and modifying them before exploding!

Very nice!!
how did you do that part in 3:40 ? did you just click on the midpoint and drag again to the endpoint?
excellent work
At around 2 min you said that the far point would end up directly above the center point. How do you know that?
The only things I know about the geometry of a dodecahedron is that the sides are pentagons, and the tip of the "side" is directly above the middle of a flat pentagon. I honestly could not even tell you WHERE I learned that!
Aaron Dietzen that’s mathematics
you surely showed him!
WTG
Great Video
Excellent tuto, thank you
This is great, thank you! How do you make it into a 6V dome from here? Is it possible?
Are you talking about a geodesic dome?
I'd love to see Aaron do that, but it can't be done using this method, I don't think. I've seen others do it. Use search on YT to find it.

HOW do YOu change the protractor position ?
How did you "Toggle through your inference options" mentioned at 3:15?
The arrow keys will allow you to snap to the different axis.
"Beautiful, Ugly Deformation"
Nice demo Aaron... does the same 'no math' method apply for an icosidodecahedron???
Uh... OW! My brain just quit!

I've done all of this but if you zoom in close to the edges of each side, they don't meet up right at all... how do i fix that

Please, what is the maths name of the arc ?
Joan lol

Abhimanyu Ghosh If you can’t swing a 3D mouse, it’s pretty hard to beat the simplicity and power of the scroll wheel on your mouse!
no math Fkn finaly. Thank you wery much
make the pentagon a component instead of a group
follow the steps
make some extrusions and insets so that it looks stupid
profit
Homer Simpsons favorite Platonic solid...sorry. Thanks.
Istead of drawing arc or vertical centre guide line - Just rotate each side upwards - type in 63.435 degrees
it is not exactly , it"s just aproximative. His method is exact.

how to add music or sound on google sketch up ?????
why

God I hate the fact that I can't swap the Pan/Orbit keybinds; actually the only thing that keeps me from using SU
Push the mouse wheel for orbit, hold shift at the same time to pan.
sorry - it used Math
TBH I hate sketchup
