Scaled array

pilou

Ok that works like a charm
except that we must find first the "Growth point"!!!
the "bottom point base" of the troncated crossing edges top Pyramid!

Maybe this can be automatic because in this case its' easy to find it but in case of complex form?
Or biggest volume?

Mr TIG it's your turn

Gee, I'm glad i stumbled on this; I like Pilou had an old version....TIG, is this only relatively new? I just went to http://www.crai.archi.fr/RubyLibraryDepot/Ruby/em_edi_page.htm and the old one still downloads.....

TIG, Have you produced a instructions sheet with this latest version? I am having trouble executing what i want to do. I seem to be confused as the the 'X' and 'Y' planes....
I assume 'X' is red direction; left and right,
'Y' is green direction; up and down the screen,
and
'Z' is obvious.

When I rotate a vertical ['Z' plane] object around what i think is the RED direction it actually rotates it around the GREEN...['Y']

Also, TIG, can you give a little detailed explanation of the order of parameters...?
I have been getting an awful lot of Bugspats!!!!

Don't get me wrong, I think once I get the concept of it I will have found my new favourite plugin!!!

@Utiler
Z Is not obvious, with it your model goes in the 3D space up & down!
there is a little help text inside the code plug! Open it

It's around the BLUE AXIS

Order gives you the natural order of transformations

About the first problem seems you can't oblige to have 80% for have perfect fit if you don't know the other X,Y,Z measures!
it's depending of the measure of the first start volume!
See my example above! I have 50% for this one (of course with my start measures volume)

My regulates and don't forget the Growth point position (see image above)
nb copy 3
X spacing = 0
Y spacing = 0
Z spacing = 100 cm
Scaling = Yes

Xspacing scaling = 1
Yspacing scaling = 1
Zspacing scaling = 0.5

Xcopy scaling = 0.5
Ycopy scaling = 0.5
Zcopy scaling = 0.5

(all exponential+ by default)

Move Scale Rotate order (or Move Rotate Scale as the is no rotation in this one)

Thanks Pilou,
I believe Z is always vertical [blue axis in SU]. If the ground plane is the ground then it makes sence to me that Z [blue axis is vertical....

See the simple Palm tree attached.

Say I want to rotate copy and move the palm fron as noted on the attached image. Still getting weird outcomes when I try to do so...

thanks in advance.

GrowTest.skp

pilou

Something like this?

utiler

No, Pilou. As a Palm fron grows [pardon the pun], it faces the sky with it's flat side facing up. Sometimes, slightly rotated but for the purpose of the exersice, lets keep it simple....
This is what i mean.

Then copy and rotate various frons to thicken up the folage...
Then do a little 'Fredo' bending....

So thats what i want to do with grow, however I just did this example manually...
Skippy attached FYI...
Thanks for your help with this idea, Pilou, much appreciated!!

GrowTest01.skp

pilou

Ok I see
Maybe monday a result

utiler

Thanks Pilou, look forward to your reply..

utiler

Pilou, My Grow dialouge Box looks a little different.... older or newer?

utiler

Still not working....
Not getting the same result as you even though I am imputting the same data...

Ready to un-install.

GrowTest.skp

pilou

You have an older version!
The last version were in this same thread always by TIG

pilou

Maybe this
But in fact all gives cool results just try different little variations
Palm's pull up is given by negative value
Here with these regulates (click image)

utiler

Damn!
I hate it when i feel amateurish...
Thanks Pilou, I think I am on the right track now. I will post some updates later.

Thank you kindly for your persistence.

utiler

Ok, I have loaded the new 2.1 version...

Did a little axis directions text [see attached.] It eems that the X axis directions are back to front. I would have thought that the postive directions would have been forward and the negative direction would be backwards....

Also, rotations around the Z axis are anti-clockwise. I thought it makes sense to have postive rotations clockwise and negative rotations anticlockwise.... [see also attached]

TIG, is there any reason for this?

Eitherway, I think i have it worked out.

You need to experiment with the 'Growth Point' origin in different places ?

hm... I wonder if there is a copy+rotate plugin out here already...

My Grow.rb already does this - there is an example of how to make a helical staircase in its thread...

I'm not finding it easy to find it - is it this? http://forums.sketchucation.com/viewtopic.php?f=180&t=20195&p=168380&hilit=+grow#p168380

It'd be best if it was in a thread by itself and not buried inside another thread.

Perhaps we could start a new thread to resurrect it - next week ?

That would be good.
Didier and Fredo had/has some old versions laying around as well. I noticed the last week several users seemed to have been downloading them instead of the new versions - despite noticed about newer versions. So I wanted to do a sweep of the plugin section and remove old versions and lock old obsolete threads. With the permission of the authors - in case they deliberately left them out there for legacy reasons.
