HELP: Adaptive component + nested family + locked position = broken panel. Why!?

[jesse.pyeatt674861]

Hello again everyone... it's been a while!

I'm working on a curtain-system facade where the majority of panels are rectangular and can host custom curtainwall panels without issue. However, due to the building geometry, there are a number of 'cut' panels that have 3, 4 or 5 sides.

I have built an adaptive component to 'fix' these panels, and they work fine (ie, can be manually placed at the atypical locations).

However, within the adaptive components I need to nest a face-based family to represent the point-supported structural tieback. I can place the structural ties, but I cannot control where they occur. When I lock them to the desired position, they 'break' the family and all instances within my Project File are deleted. In the attached family I have inset a series of reference lines 100mm from the edge of the glass panel. I can align the struts to these lines but they don't stick. If I lock them... the panel breaks. I've also added points at the ends of these reference lines... but same story if I lock the struts to the endpoints. It breaks in the Project.

I would like to position the 3x struts 100mm inset from the panel edges. Can anyone please help?

I've attached three files:

• ADAPTIVE_markup.jpg - This shows where the struts should be located.
• ADAPTIVE_application.jph - This shows how the struts fly off into space in the model.
• ADAPTIVE_3_point.rfa - This is the family.

Many, many thanks for anyone who has time to look, comment or otherwise help!

See attached. This should work.

Generally, you need to use points by intersection, and host your ties on individual points.
