Trying to make triangular curtain wall grid . . . not mass.

[josephclee]

I am working an exercise of using Dynamo to randomize the curtain wall triangular panel colors. In order to randomize the panels, I need to select each panel. I created the mass with pattern (Triangle Flat). However, the Dynamo node can only select the panels from a real Curtain Wall element (See below the 6x6 rectangular curtain wall). It can't select and read the panel from the triangular pattern mass. Is there a way the Dynamo can read the panels from the mass (red)? or a way to make the Revit Curtain grid triangular?

The situation is . . . the Dynamo can only read a real Curtain Wall . . . not from a mass. See title.

Curtain Panel Pattern Based is a curtain panel family.  Dynamo will read it.

Can you show me the Dynamo nodes will read the panels from a pattern base mass?

It is the same one you use.  Feel free to share the script here if you want a test run.

The nodes in the image can only read a real curtain wall element but not from a pattern base mass. Why don't you try it?

I suspect you did not read the instruction carefully.  Please read it again and watch the video.  There is a step of assigning a curtain panel pattern based family to the divided surface.  Did you do this step?

[josephclee]

I already made the pattern base mass triangular curtain wall mass. It doesn't work for the Dynamo node. See the attached image at the beginning of the post. The red ring is a pattern base mass. It doesn't work for the nodes.

You can create your Dynamo nodes and pattern base mass to prove it work. Please don't guess it will work.

You keep saying mass.  A mass is only the beginning steps of the process.  There are more to it.

Did you create a curtain panel pattern based family?  Did you load it into the project or the conceptual mass and assign it to the divided surface?

I don't see any panels in your screenshot. I see a 2D Triangle (bent) divided surface pattern.  

The next step would be to create the 3D panel geometry in a Curtain Panel Pattern-Based Template and then load it into the Family/Project having the Divided Surface and assign it to the Divided Surface the same way you assigned the Triangle (Bent) Pattern.  Note: Make sure the Material Parameter for the panel geometry is associated to an INSTANCE Parameter in the Family Types Dialog Box.

Okay you win.  Your script doesn't work because it selects curtain panels based on their host (a curtain wall) and Pattern based curtain panels don't have a host.  Use Select by Family Type node to select them instead.  You can have one family type for each divided surface so you can run the script on each surface more easily.

Thanks for the graph. It works. Maybe the node I used was the problem. Thanks for taking time to show me the Dynamo.

[josephclee]

Will the Dynamo work if the mass is in the Revit model?

[ToanDN]

No. It only works in Conceptual mass family environment.

[josephclee]

It works on the conceptual mass. The next step for me is making schedules for each of the panels to show the colors, size and position.

Load the conceptual masses in a project, tag each panel and create curtain panel schedules.
