radiused drywall corner

[billemery]

I just figured out that Chief will produce a very nice radiused drywall corner using a double wall.

In this case I have one wall as half inch drywall, and the other as 3-1/2" framing with 1/2 drywall on one side only.

One nice feature of doing it this way is that the moldings will follow the curve. Another plus is that the radius shows properly in plan.

Ok now, you know the base board hasn't a radius and doing the three piece corners w/base if not done yourself may as well give the house away for the trim carpenters price if he does it right which is unlikely....Oh, just do a 90° - Do you 90° your base or 22.5 three piece it (for bullnose corners)?

- Accomplishing the "radiused drywall corner" with CA is a feat as I believe most have given up trying.

You can buy round corners for the baseboard.

That looks good Bill.

Think you could give a more detailed description of how you made it?

Thanks

Jere,
The first step is to define the wall types. One has a single layer of half inch drywall. The other is the 4-1/2" interior wall with one layer of drywall removed, for a wall thickness of 4".

First draw a straight wall with the the drywall only. then draw a curved wall with a tight radius with angle snaps turned on to get it to a 90 degree arc. Then draw another straight wall to complete the corner.

Now I have the outside corner; next I draw the inside walls using the modified interior wall type. I then move it in until it touches the 1/2" drywall wall.

I then select the walls and check "double wall" in the DBX.

Here's a nice radiused window wrap as well using a molding polyline.

Neat trick Bill. Have to wonder WHY this happens? Did you just stumble across this?

- A good point, though have not found that for the various bases used in these type homes and the the cornered base does not look bad but is an added expense.

Hi Bryce,
I've got a client that likes this look in a plastered wall. I've seen the various work arrounds, but wanted to find a better way.

I first started by breakintg the wall near the corner, and changing the wall type to one with no drywall on the outside, and then filling the corner with a polyline solid with the curve and short straight sections, which looks good, but I didn't want to see the wall breaks in elevation

It then occured to me that if the wall wall thin enough I could turn a very tight radius. It then hit me that the double wall was the solution.

We do have the radiused trim pieces available here in most common profiles which are much easier to use that the mitered method. We also have corner bead transition pieces here that allow us to transition to a square base.

The issue of different base configurations can be solved here by using a modified room polyline molding.

I've been having trouble with the way doors trim out in this double wall, so I'm breaking the wall just out of the corner and using a regular interior 4 wall. This still gives me a seamless look in elevation

Thanks Bill, very interesting.

Bill, very nice workaround.

In these parts, drywallers charge about $15 for a 'transition cap', and trim carps (myself included) charge between $10-$15 for double miters. The molded base never seams to match the straight molding, especially if its to be stained, and is not used too much.

Brilliant work Bill!
I'm mostly following you here except in the selecting the walls and checking the "double wall". I've tried selecting the walls one by one and all but the curved portion will allow me to check the double walls. The curved wall is greyed out.

Now I may be doing something different.
I am making an exterior wall with one of those tight (8") sidewall craftsman style soft corners.
So I made a 3/4" siding wall as my "exterior" and a framed 5 1/2 with 1/2" gwb "interior" wall.

But so far I'm not quite able to get all three straight seqments of the framed interior wall to merge with the 3/4" exterior wall, right at the curve. The frame portion which is 90 degrees pokes through the 8" curved portion.



Suggestions??

This is very nice Bill.

OTOH, it would seem that CA could provide a default for "Outside Corner Radius" for Interior and Exterior Walls. They could also add this to the Walls dbx and make the rounded corners automatic. This would be a really neat addition for X5 - a little something extra

I'm on the beach in Yelapa,Mexico; a village only accessible by boat, so I'm not near my computer

It's been a while back since I did this, and I'm guessing that walls may have changed enough in X4 to make more difficult.

I'll check it out next week when I get home.
