Louvers? Louver Wall?

[TMM]

Hi,

I am trying to model a louver wall in VW. 

Here is the image below. 

Is there any way to model this wall in VW? Or should I make a series of extrusions and group them together?

There are a couple of ideas you could try in this thread:

 

 

1) A secondary Curtain Wall or 2) a single standard Wall with a Wall Hole Component symbol applied to clip away material to leave behind the louvres

Hi, thank you so much! 

 

What does a secondary curtian wall mean? 

 

Do you mean just create a curtain wall and change the grids inside? 

 

Thanks! 

[Tom W.]

No problem!

 

Yes create a Curtain Wall that consists only of vertical butt-glazed frames + it will look something like this:

 

 

You will need to place it in front of the main structural walls as a separate object. And you will need to insert Openings (Windows) in it that correspond with the Windows in the main walls as the windows will only clip the main walls.

 

If you go down the Wall Hole symbol route you would just have a single wall so the windows would punch holes in the cladding as well but that doesn't necessarily mean it's a better method. I suppose it depends how big the building is + how much cladding there is + how quick/easy you want it to be in terms of changing things around should you need to.

Sometimes you can do something like this with a simple extrusion, that ends up being no less fiddly to edit than something like a curtain wall object.

 

Worth remembering that an extrusion can be formed from multiple polygons. So, duplicate-array a rectangle, extrude all of those duplicates in one operation to the maximum height of the wall. Then you have one extrude object. To cut window openings or adjust the edge shape of the louvred wall portion, create some basic solids and do a subtraction from the extrude object. Those subtraction solids you can also create as a single, multiple-polygon extrude, extruded perpendicular to the louvre extrude.

 

If you set that up properly, you then have a single, "solid subtraction" object which you can double-click to edit either of two objects in order to make adjustments (which can be done in a precise way in an orthographic view simply by flipping to top/plan view when editing the polygon(s) that generate the extrusions.

 

Could also be done as an intersection solid -

 

 

 

 

Just as @Tom W. says above, the best method will depend on all sorts of things like the complexity of the geometry (for example, I don't think a curtain wall would let you make non rectangular louvres, and editing walls with horizontal/vertical profiles can be annoying) and how important it is to be able to edit it subsequently.

 

(By the way, it's always a frustration that extrudes don't seem to be allowed to contain symbols. If the louvre extrude object could be made up of an array of 2d symbols, then you would have a way of editing the louvre profile without redrawing things)

Surface Array is another option if you're going down the solids route...

Hm, I never use Surface Array; I should take a look at it...

[Tom W.]

If you use the Extract Tool on the Wall/s to create the surface that will form the basis of the array, the surface will miss out the doors/windows + therefore the array you then create will have readymade holes in the right places: no need to clip them afterwards.
