array (duplica) with rotation and spacing that decreases

[kubbah]

Hello
I would like to make an array of elements that (as from image)
a: the spacing between the diminiusce elements
b: the spacing between the elements decreases and the elements rotate progressively
https://docs.google.com/file/d/0b9ww_0_r5bzqdurywvc3b2jssfe/edit?usp=sharingWould someone know how to do it without resorting to rhino?

elements are columns under a cover.

Thank you very much for your help

Since we speak of structural elements, the first certainly would do it with the use of grids...and perhaps also the second (unfortunately I fear there is no automatism)

 

[Tristan]

kind of thing:

 

[kubbah]

Thank you!
the answer is interesting. ...
but I would like to understand if there is an automatic possibility, introducing certain algorithms/parameters. . .
because we imagine that there are 1000 of these elements. . .
It's where revit zoppica I think... but I hope I'm sorry.

 

[Tristan]

I fear not...the command "array" of revit is not particularly evolved unfortunately

 

[kubbah]

What if I create a family?

What if I create a family?

And then? ...

 

[Alfredo Medina]

it is not possible with "array" but with "divide & rep" and adaptive points.

 

[kubbah]

hmm pooresti give us more details?
Thank you very much

progressive spacing and rotation. How?

here you find some info
http://wikihelp.autodesk.com/revit/...prelimin135/0204-conceptu204/0319-associat319the procedure for creating adaptive elements is quite complicated but perhaps it is the only chance.
@alfredo
a pregunta: but are those elements in the project seen as pillars?

I didn't do that, but I think it should be possible, like "shared" families.

(fast lesson on how to make an adaptive repetition, extracted from my conference to auckland, in new zelanda, last week).family 1This is the object we want to repeat. you start with the generic model. In this case, it is a rectangular column. basic work-plane.
family 2This is the repeater. you start with a generic model adaptive. it contains 2 adaptive points and 2 reference points.
point # 1 adapter is the point that goes to every knot of the divided path.
point #2 adaptive is the "cursor" or "control point". we measure the distance between these two adjustment points and convert to "x", a reference parameter of instance.
point # 1 reference is created the vertical worktop of point #1 adaptive, and its offset parameter is set to "s" (paint).
point #2 the reference is created on the horizontal working plane of point #1 of reference, and its rotation parameter is set to "a" (angle). the angle is set to be "x" times a rotation value for each step.
this family also contains a parameter to help spread repetition in and out, if necessary "s_factor" (space factor). the distance is set to be the square of "x" times the spacing factor.
family 3This is repetition. you start with a generic model adaptive. it contains a divided path and an adaptive point. the adaptive point in the repeater is where we need to locate the "second click" when we place the repeater on the split path node.
workflowfamily 1 is nested in family 2, and placed on the horizontal working plane of the reference point 2.
family 3 should contain a divided path and an adaptive point. it also contains a "s_factor" parameter (space factor), and optionally, a "#" whole parameter to control the number of split trajectory points.
family 2 is nested in family 3, placed on face on one of the nodes of the divided path, and the second click is placed on the adaptive point. family "s_factor" 2 at the local family "s_factor" 3.
select the column, and click on "repeat".
change the spacing factor if necessary.

we see all this in motion:
