PS Have you seen the little Conoïde membrane problem?
It's for you!

haha.. i haven't opened that thread yet.. and i better not -- i have some things to do today..
ok.. maybe just a peek

[EDiT].. same thing for that as this.. the conoid membrane is literally a 30 second deal in rhino and that's how i would draw something like that.. since this is a sketchup forum, i'll refrain from posting "use rhino for this" in yet another thread..

Jeff, Please don't refrain from comparing with rhino. Im learning it currently, and Im very interested to see how you attack these problems with Rhino. I've see it on a few threads. Im Very curious how to make the conoid membrane with Rhino. Im really quite new with it.

Jeff, am I missing something your approach makes me feel like Im missing some essential detail or a technical consideration. Have i missed something?

how does it look? it sounds like it looks similar to the (incorrect)example i posted at the top of this page(3) whereas the picture posted in the original post has a pattern of alternating triangles... a pretty big detail both structurally and visually..

V^V^V^V^ and not |\|\|\|\|

(lol at me trying to draw the pattern using the keyboard)

[eDIT]-- oh.. and hey.. i'll be the first to admit, i'm usually pretty damn picky when it comes to detail..
(ie- most of the stuff i draw irl has to then be built.. i can't just draw a sort of shape then start pulling vertices around (ffd style) and say 'ok, that looks about right' then go try to build it.. that would be a nightmare build and it would more likely than not, collapse )

so, when you see the sketchup method i posted on page 2, realize it's an attempt at making properly outlined geometry (systematic geometry? understandable geometry? idk) for building purposes as opposed to viewing purposes)

PS. I also took a run at this.

I used the same technique as gill to get the Basic shape.

Then I use lattice maker but with a depth of 0 to generate a lattice structure with windows (essentialy offset faces) - sure to assign separate colors/textures to the glass and lattice so you can 'select by color' later.

So, I have the 2d structure. From there I just used JPP to get the thickness of the lattice, selecting by color, pulling outward.

I finish the building with JPP, select by color and creative grouping and ungrouping to get proper depth and placement for windows, which are two pane and inset.

Réclamations!

that looks nice..

@yitzhar.. do what bazel is doing.. it's a lot simpler than that path i'm trying to lead you down

jeff hammond · 13 Jan 2013, 03:33

fwiw.. one reason why the approach i went after might seem longer than necessary was that i was trying to draw the actual building from the original post (within reason).. it wasn't until later in the thread that yitzhar said he only was after that style and not the building itself..

Ahhhhh, That what I imagined. Your approach at getting the shape seemed so systematic and precise, I figured there was a world of secondary (arguably primary) considerations I was not getting, as a pretty picture maker...hahah

Yes, precise systematic geometry. I get it.

Glad you like, im going to throw a roof on that puppy keep playing.

Can we expect a picture of a wooden version in the next few days?

haha.. no
hopefully something that starts to approach the coolness of this building though a lot smaller.

PS. Jeff BZ-Convert in step 2 of your technique. Can you elaborate.

I understand the top and bottom must have equal segments to get the nice/proper quads from the loft, just not sure what role that plays?

I see the beauty of your technique, all about the accuracy.

oh.. right.. i guess those 'instructions' i wrote are very vague

if you have fredo's BezierSpline plugin installed and you right click on a SU curve, you'll see an item called 'BZ- Convert to >'... within the flyout menu that comes up, i chose 'Polyline Segmentor'.. this will enable you to divide a curve into a given number of segments of the same length.. here's an example using an ellipse

(but this also works for changing the # of segments.. the ellipse didn't need to have 10 to begin with.. i'm just using it as an example to show a SU ellipse will not have equal segment lengths in the same way a circle will)

the reason you can't do this on the vertical profiles is because the floors would end up at wrong heights.. when the building is close to true vertical, it would have ,say, 12' floors and the more bent parts would end up with maybe 8' floors..

that said, i've thought of an easier way to do that step instead of using the arrayed plane.. not sure why i did the planes in the first place

yitzhar · 13 Jan 2013, 12:41

jaff, i you right about the way you wrote, the meening of all this treade is not just making
almost the same shapes, as an architect we want to the design accurate for later building
in the real life and not just for the show.

jaff i think the way you present for doing that is the best way, i tried to do the V shape
but i dont realy understands the prosess of the drawing the v shapes.

Ahhhhhhhhhhhhh, paneling tools why are you so sweet !!! Yes!

Seems relevant to mention that it took Rhino like 4 seconds to generate those panels....Just saying.

Both planar and 3d panels.

haha.. that's what i was trying to say way back in this thread .. use rhino to do this kind of stuff..
i guess it doesn't sink in until you try drawing it in sketchup and in rhino..
