How to array families on curves

Revit
#1

Hey Guys,

Peace to all who are reading this Topic…:grinning:

I want array family file like this…

So I made graph like this

But result is…

  1. Dynamo does not allow families to be spaced below 250…
    K-007
    K-007.jpg1936×1056 280 KB

the Korean error message says, “The value is too large or too small to fit the format Int16.”…

But since the length of the family is 250, I have to arrange it at 250 intervals

  1. All families have to be rotated to the curve, and now the families are rotated at the same angle.

    or
    K-005
    K-005.jpg1936×1056 162 KB

  2. I want these families to be arranged naturally along the curve…
    Also, sometimes need to control the family so that it is not arranged in any interval…

How can I do this…?

#2

what is the curve length which you are trying to divide by 250?

#3

Total length of curve is 8,000,000mm… about 8km.
So long… and family length is 250mm

Is it related to length?

#4

is this an out of the box node? My guess is that it’s using the parameter of the curve from 0 to 1 - there might not be enough precision to divide that nicely into 32,000 parts in between 0 and 1 with only 15 digits that floating point numbers support. I would try slicing the curve up into 10 parts or so.

Thanks : Michael_Kirschner2,
I Think “DividecurveByDistance(LunchBox)” has problems with this.
So I tried to use AdaptiveComponenet.ByPoints …

I want to place the families on a 3D curve and the families to be placed in the vertical direction of each tangent.

This is related to old topics,

but I can not see the image because it is too small.
How do I align rotated families onto a 3D curve?

#6

make your family based on some extra points (not a single point) and then use the normal or tangent of the curve at that point as a second alignment control for your adaptive component.

#7

Thank you Michael,
I Tried it in two ways.

First, I tried to use “FamilyInstance.Bypoints”
this is working…
However, it does not rotate in the direction perpendicular to the tangent of the curve.
I do not plan to build a staircase…

After your advice, tried it the second way.

“adaptive component”

but the result is…

adap

maybe something’s wrong…
What’s wrong with it…

#8

With another value in Settings -> Geometry Working Range?

#9

Thanks, franciscopossetto
Geometry Working Range is largest…

This is result of “adaptive component”

I can’t understand how “adaptive component” working…
