[Tutorial > Modeling] Helical Dome
-
This is one of the ways of making an Helical Dome in SketchUp.
Feel free to change the English explanation if it is not well done.

Iglesias,
Interesting and creative. Thanks for sharing.

urm... just looking at the starting slide, how do you slice profile 20 divisions or fillets??
Many thanks -
Hello vinnie,
When you make circles, circumferences or arcs, SketchUp shows you the number of sides, by defect 24 for circles and 12 for arcs, you can change typing the number of sides you want, previously of typing the dimension of the circle or arc.
-
I see. thanks Iglesias. So to make the shape shown on starting slide. I create a circle (with 24 segments as default), then draw a circle each snap to midpoints, then delete anything unwanted to create the shape.
Just wondering if sketchup got a function like array (or polar array) just as in autocad, which makes life a lot easier when rotating things(or copying).

Hi Vinnie,
Read more about "Radial arrays" here

and "Linear arrays" here in SU:

Can someone tell me how to make an helicoidal stairs ?

Here's a helical [spiral] stair step-by-step example using 'Grow'. [Sorry for the terrible pun on 'step' !]
However, you can do it all by hand - if you have the patience. First make a component tread, rotate+copy it around the required angle/times [15degrees x 15nr], then select all treads except the original [tread1] and move them up by the riser height [in the example it's 170mm], then de-select tread2 and move the rest up by the next riser, de-select tread3 and move the rest up etc etc, until they are all at the desired heights. All 'Grow' does [in this example] is copy/rotate/move-in-Z - all in one-step which will save you time...

I find this method incridbly usefull but i will check your plugin too…

That 3D Warehouse file is from an Official Google SketchUp Blog entry from July 3, 2009, at http://sketchupdate.blogspot.com/2008/07/building-spiral-stairs.html
Nearly all of the comments on that Blog item are spam.Does anyone know how, who, or where to report such spam and get it cleaned up? I ran the Chinese post through babelfish and it's clearly advertising adult content, on the blog site since November.
-
You can try to report it in the Beta forum (I have done it a couple of times). Those blogs should be maintained much more regularly and better.
-
Ah, the Beta Forum! Good idea. Not exactly public access though.
On the Blog pages next to all the spam is the note "We're interested in your comments" that turns out to be a link to the main Google Group. I figured it would not get any more attention there than on the Blog page itself, so why bother.
Thanks,
August -
good thank
