How to make non-rotation families with adaptive points

[Anonymous]

Hi, All.
Now I'm trying to modelling tunnels by Dynamo.

but
However, the created families are rotated to the linear center axis.

I think the problem is in the way I make the family.

I created three points on the plane and converted them to reference points.

And Loads CAD files and drew profiles by pick line.

I connected the reference points to the spline, and selected the profiles together to form them.

I thought this was over, but when I drag and move points,
It rotates.

It rotate.
I cannot control this unwanted rotations.

If I want to prevent such unwanted curve rotations, I need to create another adaptive point in the Z direction.

But you know,
then, we have to create 4th points of curve, maybe offset points, this is impossible in 3D curve.
this is different from the “translate point”.

We should not create a fourth point outside the line.

Please, let me know a little clue.
How do I fix my family? How to make a family?

Zack Kron had a nice Youtube Video that was out there on Adaptive's and how to get them to behave the way you want them to.  I believe he had a similar example.

Near the 20 min mark. 

I know he's also got a little family that (triangle jig?) that might help figure out where things are going wrong.

Hope it helps.

It helped to understand the direction of the reference point. Thank you.
However, the family I make is a little complicated, so I have to Load the CAD and draw the line by Pick Line.

In this case, it seems that direction specification does not play any role.

The family is constrained to the reference point, but it seems to be moving independently of the host.

All case of Point orientation, rotated

So I'm wondering if this is a point issue and it's not selecting the points in order in which you want them placed.

Paul Aubin had an AU class that was using dynamo to place adaptive curtain panels on a sloped wall.  

The Graph he was using was picking the points based on distance from a point..  Knowing that a point off in space can be set so the nearest point is always first and so on.  You might want want to take a look for that one.  Not sure if that'll help, but it might.  Just trying to think of other things that might help you you.

Hope it does.

Thank you very much,dtpeter2901 

I'm looking for the graph you talked about, but it's not easy.

I could not find topics about 

"place adaptive curtain panels on a sloped wall",

Can you show me more Information for me?

I wish this will help me, too.
