How do I create a trapezoidal glass block window in a curved wall?

[dd4st]

Hi,

I have a semicircular staircase against a curved wall.  I need to place a glass block fixed window (no frame) in the wall that follows the staircase.  In other words the sides are vertical but both the top and bottom slope up.  I've figure out how to fake it in another curved wall where the glass block is rectangular by using a bow window with all the appearances set for clear or glass block.  However this doesn't work for a trapezoidal shape.  I thought about stacking walls on top of each other and changing the appearance of one section, but when I try to do that by elevating the wall the wall below it disappears.  Any body ever solve this? 

Thanks

Hi Dan,

I will have to experiment with this but I am have to out for a few hours so can't right now.
First thought though is to try sloping top and sloping bottom walls on different locations and use a curved piece of wall (exported as a 3DS and imported again, to serve as the 'glass'.

There are probably other ways but no time right now. Will get back to you if the above does not solve the problem for you.

Hi Dan,

Sorry about the delay.

Did some testing and found you can easily do what you want, if I understand correctly, just using walls.

In the example image I had a thin wall with all surfaces set to the Glass Block texture on a copy of the Ground Floor (same settings as Ground Floor). The lower slopting wall was a slope top wall on the Ground Floor itself and the Second Floor had a sloped bottom wall. You will have to fiddle with the height settings of the slope to get the angle you want and the height of the window. In the example, I had the 'a' set to 6' and the 'b' as 6" and the reverse for the bottom slope on the second floor wall.

Not sure how familiar you are with the program - if you need more details just ask.

Allan,

This works!  I didn't think about trying a second floor wall.  The slope wasn't bad to figure out.  What was a little tricky is I had to elevate the second floor wall a negative amount to get it to come down.  I couldn't set a negative point in the wall slope.  I've got another place where TFP wants to slant the edge is a square wall sitting on top of a curved wall.  Seems TFP doesn't recognize walls at different heights ant treats them all as merged entities.  The second floor option may fix this.  Too bad one has to figure out work arounds to do this.  Me thinks TFP sometimes tried to be too smart.
