[Obsolete] Joint Push Pull
-
Thank you Fredo. You think you've seem it all and then....WHAM!!! There have been many times I could have used this. Most recently, yesterday while trying to increase the overhang of an octagonal roof.
Edit: I got a kick out of your "Seidel-Gauss algorithm and the Choleski linear resolution matrix" footnote in the tutorial PDF.....LOL.
I would LOVE if this could work in version 5. It almost does now.
Edit: I noticed that after running the script some of the edges of the extrusions are hidden and the sides of some extrusions are not perpendicular to the face. These 3 faces were selected at the same time. This only seems to happen with polygons. See image below:
Edit: I now understand why there are hidden edges. When extruding multiple contiguous faces, the common edges are hidden to give a smooth look. You can see this when you select Hidden Geometry or explode the group. I guess when you extrude only one face or non-contiguous faces (like in my example), the script "wants" to hide an edge.

Great script! It's like offsetting whole faces instead of just lines.
I just wonder why all these functions are not included in SU!Thanks a lot!
-
Thanks! I was just wondering how to do this.

Edit:PS. Yes.. like bellwells says... there are hidden edges.. in a lot of cases don´t looks good... would be better to use "soften edges"
Actually, I did not know what was the most appropriate, hidden or soft, because there are advantages for both in any situation.
This is easy to fix (see attached file modified).
The question is whether I leave this as an option
-
thanks a lot! the tutorial by itself is a masterpiece, and you are definitely breaking new ground with your Choleski linear resolution matrix
-
Fredo, t'es trop fort !
-
Fredo, Thanks

Error; #<NoMethodError; undefined method `classify_point' for #<Sketchup;;Face;>>SU5/Win
Later Edit: my bad, didn't read the complete tutorial where it said that it is not SU5 compatible
-
I still can´t believe this! It works great with high poly models and makes brillants results. Incredible to make this inside SketchUp.

Fantastic, enjoyed playing with it. Now I need to find a place to use it.
Thanks, Bob
PS Confirming bellwells image earlier, if you use Joint push-pull on non-contiguous faces of an polygon block then the side of the extrusions have a mix of angles, some are rectilinear (as from the Vector extrusion) some are aligned to the center of the block.

Fredo,
Just been having a quick go with your Joint Push Pull Script.
First impressions - Very impressive. Will be really useful.
...
Joint Push Pull - Excellent
Vector Push Pull - a really good idea to include this also - Excellent
Manual / Tutorial PDF - Very Comprehensive / Well written and easy to understand.
...
I'm not too sure about the "Reverse Green Axis (-Y)" - you've assumed that the Green axis will be orientated away from the observer.
IMHO I wouldn't assume that.
I think it would be best if it was "Green Axis (+Y)" - like the other axes.
(Crops up in a couple of dialog boxes / dropdowns).
For the Vector Push Pull Method, it might be useful to somehow include an option for "interactive" - so users can push pull on screen (eg along the red axis for example).
(I'm not sure if this is possible).
...
Fantastic Script.
...
Belated Thanks for your BezierSpline Script - also excellent

hi fredo,
fantastic! what can i say that the others have not said? anyway, just want to thank you once more for a great script which will be of great usefulness to all of us.
and congratulations on your generosity.
regards,

Hey Daniel how did you do that chair? With soap skin and bubble?
-
Wo... (didn't even finish the word playing with Didier's component spray that something else comes up!) ...oW
thanks Fredo
(now i just need a dialog box to automate english weather control and embed that in SU)..
-
This is very generous, thank you.

Thanks for appreciation.
Regarding the non contiguous faces, what you get is normal, because it depends on what you want to achieve. If you wish the borders to be perfectly normal, you must select NO in the option "Extent influence to non-selected neighbors", as explained in the Tutorial, in section 1.7, p.12. Otherwise, the macro compute the direction as if you would also extrude the neighbouring face. Unless I missed something....Fredo

Very good script
, but in SU5 unfortunately does not work ...

Fredo, I do think that there is something here that is not consistent with "as if you would also extrude the neighbouring face." See this diagram (plan view of an extruded dodecagon). Notice that the two end extrusions of the five contiguous faces are different. (I did these both on the same dodecagon for simplicity but I get the same result if I do them on separate objects so I don't think there is interference between them.)
Scratching my head here but I don't see an obvious pattern.

Fredo,
I can just add to the rest: you have created a very nice and very usefull ruby. Thank you very much for sharing this with us. I am not an architect but a productdesigner and do a lot with double-curved shapes and surfaces in SU (6-pro), on a mac.
Today, after carefully reading your tutorial (which also is a nice piece of work), I have taken quite some time to play with your ruby and I have tested it with all kind of shapes and surfaces.
First: I am more impressed than I thought I would be. As long as you start with a clean surface, your ruby works without any problem at all. I really went to limits and over. Going over fysical limits creates impossible and unexpected shapes, but your ruby never stopped working.
Second: I can reassure you, your ruby performes without any hesitation on (my) mac.
Third: In your tutorial you mention your ruby might still be a bit slow. To my opinion, your ruby performs oke. Yes, if you start with curves, arcs, ellipses divided in 360 or more segments and create surfaces with 100,000's of edges,faces, instances your ruby needs time. But not more than others. As we all as pro-users know, such's details aren't necessary to create nice shapes in SU.
Fouth: as all tools, also your ruby has its own limits. But, in the 3D-world it is impossible to create a tool that thinks for us. Your ruby is a very usefull tool, makes quite some SU actions easier and much faster to perform. Together with existing SU functionalities (standard and rubies) it enhances the possibilities of my preferred piece of 3D software: SketchUpBy the way:
The number of powerfull and usefull ruby's is increasing rapidly and we have seen some promesing developments almost ready to become available to all of us. If they would all be packed together in nice way, we would already have a nice and powerfull new SU 7 pro. Looking at my SU screen, compaired to beginning 2007, I look at something quite different (and I feel happy about it).
Thanks to you all !!
I start thinking we are making life difficult for all those folks in Boulder, working on a really new SU 7.
What can we expect from them that will really surprice us. Of course, there are still more than enough wishes and expectations, but I am getting more and more curious.Again, Fredo, also you have contributed to my new SU screen.
Many thanks to you and all other great ruby-artist to make this possible.
