Roof Design - what's the best way to accomplish this shape?

here's what I have.
A "roof" element in the design which contains a large slab. tapered in a percentage of the slab.
it also has an end taper as well.
it contains multiple openings (slits if you will) and one large opening in the flat part of the slab.

what is the best way to model this roof object?
Currently we have a designer who has modeled this as a "morph" and has placed large mass objects all around to represent the subtraction of the holes.....
Now..I don't mind doing this but...you always have to have these "boxes" in a layer that is always turned off so's as not to see it.

Any suggestions on a better way of doing this shape with slabs or shells?

If you want to get rid of the SEO operators you can convert to morph again (after the subtraction) and the holes will become a feature of the resulting morph. Keep in mind that this may make future adjustments more difficult.

This could be a solution ( using the created morph):

save the morph as an object.
place the newly created object
transform it into a morph again if you wish

hummm...I like the "create morph into object" idea.
Yes, I can see how if the design changes...the re-doing of the 'morph-to-object' recreation would have to occur every single time....

will look into this tactic.

I'm not that bothered by the SEO being in a frozen layer...that much but it somewhat does bug me that I have "shapes and masses" in a layer that has to be constantly hidden.

When you do a "select all layers" and unfreeze them..then is the only time you will SEE those floating large boxes which create the holes in the morph....but we'll see how it goes.

thanks guys for your advice.

Minor point: Freeze is an AutoCAD term. In ArchiCAD it's show/hide and lock/unlock.

Why not just do this as a slab with holes in the slab. For the taper place a temporary roof plane matched to the desired taper and use the Trim to Roof command. You can then delete the roof if you wish.

Humm....I'll try the slab with tapered edges as well:

The tapered edges start from the top of the slab, so that will not yield the section you show.

You could do two slabs - as easy as cutting with a roof, etc.
