Curtain Wall Length Parameter

tonkata — Wed, 25 Oct 2017 03:13:10 GMT

Not sure if this is possible.

I'm creating a BiFold Door family (using curtain panels). In order to show the doors in the opened position at a 45 deg angle, I've decided to nest a detail family.

The problem I face (not having a "lengths"parameter), is not being able to equally divide the nested panels.

Any suggestions?

I'm not following you. You might want to post the family. But in order to flex open and close, you are going to need some labeled angle dimensions as well.

...here: examine this one. Play with it and see if you can break it.

Associate the length of the nested panel family with the desired length parameter in the parent family.

oops Reading is obviously a must-have skill on the forum, if you want to participate. Oh well.

Any chance you have a R16 version?

...didn't read the "Curtain Wall" part of your question. Disregard attachment. It's not a CW. Still might have helped you, but unfortunately I can't redo in 2016.

Sorry Rina, I don't follow you?

The 4x panels have been created in a curtain panel family, where as the 45° line are symbolic lines create as a Detail Item family, then nested within.

I've attached the .rfa for anyone to take a look.

Please keep it as a R16 versions

@barthbradley if you think you can get it work, R17 is fine, I just can't open right now.

Well then, open the file and look at the Formulas. That's what you need to know: the trigonometry for right angles.

Didn't know there was math involved, did you?

The whole purpose of nesting families is to bring in one repeatable unit - and repeat it. In this case, all the panel door family needed was ONE panel.

Delete the umpteen other panels - only keep one. Make it horizontal. Constrain it to reference planes and add a dimension parameter to the reference planes - not the geometry. Test the parameter by changing values - the reference planes should adjust and the geometry should also adjust accordingly. THEN nest the family into the parent family.

@barthbradley never mind, I worked out the problem, it seems there was something wrong with this particular family, every time I tried adding a overall length dimension, it would tell me it was "over constrained".

Started it from scratch, now it's working just fine.

Thanks again for tuning in to give a helping hand.

@Sahay_R hmm.. Brilliant suggestion, I'll give that a try too.
