Hi guys, I'm back with another puzzle. I create objects but placing a jpeg of
the item on a prim and placing prims on the picture to match. In today's work I
am placing prims in order to difference out a window. The two sides are angled,
and match each other. The bottom is straight, but the top is at an angle. I use
a shape called wedge, that I made a couple decades ago, and almost have the
whole thing filled out. as below

#declare wedge=    //common wedge shape with 45 degree angle. One unit in size.
difference{
box{<0,0,-.5>,<1,1,.5>}
box{<0,-1,-1>,<2,2,1>
rotate<0,0,45>
translate<1,0,0>}
}

union{
object{wedge scale<.05,.48,.01> translate<2.02,.12,0>}
object{wedge scale<.25,.05,.01> translate<1.77,.54,0>}
object{wedge
rotate<0,180,0>
rotate<180,0,0>
scale<.05,.48,.01> translate<1.77,.54,0>}
box{<1.77,.12,-.01>,<2.02,.54,.01>}
}

this leaves an oddly shaped chunk in the top left corner that my mind can't fill
in, at 6am in the morning. The side and top should meet, but the wedge won't
work. Any ideas?

BTW, to help make it clearer, the locations of the four points is below.
1.72x .6y 0z
2.02x .54y 0z
1.77x .12y 0z
2.07x .12y 0z

NEVERMIND
I replaced the coding with this

union{
object{wedge scale<.05,.48,.01> translate<2.02,.12,0>}
difference{
box{<1.72,.12,-.01>,<2.02,.6,.01>}
object{wedge scale<.05,.48,1> translate<1.72,.12,0>}
object{wedge
rotate<0,180,0>
rotate<180,0,0>
scale<.3,.05,1> translate<2.02,.6,0>}
}
}

Why don't you use a prism object ?

I don't know how. There are still tons of options and stuff I never used. All
these years, I have made do with basic prims. Only recently did I use triangles
to create a shape I couldn't by the normal means.

I just read up on the prism object. OMG this will make things easier!

Yes indeed.
What will make even easier still is plopping ready-made code examples into your
scene with a few clicks from the drop-down Insert menu.

Have a look at:
Insert --->  Basic Shapes Angular
```
