Curtain Panel Family Breakage

[leis.ho]

Hi,

I am a heavy Rhino/Grasshopper user transitioning to Revit/ Dynamo.

I intended to create a variable facade system based on attractors-

The following was modeled in in Rhino/GH.

Modeled in Rhino/GH

My approach in Revit involves 3 rfa files:

1. Conceptual Mass profile for the "bowtie" sweep of each individual unit.

Bowtie Profile

2. Curtain Panel family of a single "bowtie" unit.

Curtain Panel Bowtie Unit

3. Conceptual Mass curtain wall with 2 Checkboard Pattern surfaces with Bowtie unit applied; one checkboard is indented and globally rotated 90 degrees.

Curtain Wall Checkboards

While certain UV settings provide desirable results, many other settings lead to breakages within my single Bowtie unit family that seems to disregard predetermined length parameters and symmetries; the bowtie unit loses form in ways that I don't understand. I don't think I can move onto the attractor script until this has been resolved.

Attached are the 3 rfa files.

Any insight would be greatly appreciated.

Thanks!

When you're ready for the attractor part -- I'd recommend checking out my friend Konrad at Archi-Lab. Hes done a lot of work with this. 

Here is one post that may provide some insight for you:

This type of family work is unfortunately out of my wheel house. Luck!

After messing around a bit more, i suspect the issue lies with the fact that my Curtain Panel family exceeds the rectangular boundaries of a single panel unit. 

When I remodel the family such that it stays within the bounding box, i no longer run into the same issues of losing axial symmetry.

This works fine.

Can anyone confirm this?

I had a look at your family and I think I have a better method for you.

I will record a short video about it.

See you soon.

Here is a short video to model the family you want. I didn't use any dimension except an offset parameter.

Let me know if you still want to fix your family in the first post.

Thanks for the help. 

After messing around with the files a bit more, I think the original issue was that my sweep profile consisted of a closed loop within a closed loop. Once I fixed that, the family worked as intended.
