Curtain wall louvre panel?

1826 Views, 6 Replies

I'm trying to work up a standard curtain wall type for our office, and have hit a snag with a curtain wall panel.

 

I'm trying to make a panel which will feature a louvre profile, that will sit in the curtain wall opening nice and neat, and array the required height of the panel.

 

I've made up a generic object, inserted that into a CW panel, then got that into my CW OK, and it flexs fine, but if I try and do an array then it all falls apart?

 

As far as I've got attached, all I can get to work properly is to have the top and bottom louvre, if I turn this into an array it extends outside the bounds of the CW panels left/right reference plans.

 

I also have tried to do the array based on a division, e.g. 2000/50 = array number, but to do this I need a height, and when I try and put a height in it becomes overconstrained...again, any suggestions?

There is a "quick" way, and an "advanced" way to do this. It all depends on the time available and your level of skills in making families.

 

The "quick" way is this:

 

Make a new curtain mullion profile with the shape of the blind of the louver. Load this profile into project, and create a new mullion type with this profile. Then, in a curtain wall, create new grid lines by segment, inside the panel where you want the louver to be. Then, create mullions at those new grid lines, using your new "louver" kind of mullion. Then, select all the glass panels that were created in between each louver mullion and change them to "empty".

 

The "advanced" way is this:

 

Make a profile family with the shape of the blind of the louver. Load this profile into a generic model family and create a sweep, controlled by a length parameter. Start a new family with the Curtain Wall Panel template. Create reference planes from the front view, to define the location of the first and last blind of the louver. Create a parameter for spacing, and use that to control the distance of these reference planes in relation to the top and bottom of the panel. Load the generic model family, and place it at one of the horizontal reference planes of the front view. Create an instance reporting parameter to measure the width of the panel. Associate the nested sweep's length parameter to the width of the panel. Array the sweep vertically. Constrain the array to the top reference plane. Create a reporting parameter to get the height of the panel. Use that reporting parameter to determine the number of items of the array. Load into project, and assing this panel to a curtain wall panel. The curtain wall panel must be not driven by type as the one you are using now, which does not let you to define panels types for individual panels.

Alfredo, your second solution is so obvious I didn't think of it!

 

Thanks, I'll do that instead, much simpler.

The advanced solution is simpler than the quick solution?

Alfredo,

 

I say the second is simpler as it requires rather less onerous manipulation by the end user, most of whom will struggle with something like this.

 

Worked up revision attached.

 

I've added a low detail version of my louvre so it makes it look simpler for elevations where we don't want to see a lot of lines, early stage planning drawings perhaps. I've also set the constraints so the louvres can be variable size apart, with the louvres themselves adjusting in size too. Spacing comes out nice and even as you'd expect. Louvres overlap as also would be expected, which also minimises visible linework.

Hi,

I made a quick test, changing the width and height of the panel, and your louver panel works very well. Thanks for sharing.

Alfredo,

 

Thanks right back at you, its a virtuous circle.

 

Update to my CW type attached, I made an adjustment so there are now two panel types, one a complex louvre shape, the other a simple shape more appropriate for low level detail work, whihc one you see is controlled by a tick box in the Type. I also added an allowance for varying the spacing.

 

Regards,

 

Charles.
