Hi,
can someone help with this please?

PUT -A/2,yy1+rr1,1,
A/2,yy1+rr1,1

FOR angle=alfa TO 180-alfa+EPS STEP delta
y=(yy1+rr1)*sin(angle)
x=(yy1+rr1)*cos(angle)
PUT x,y,1
NEXT angle

PUT -A/2+(A/2+e1),yy1+rr1,-e2,
A/2-(A/2+e1),yy1+rr1,-e2

FOR angle2=alfa2 TO 180-alfa2+EPS STEP delta2
y=(yy1+rr1-(A/2+e1))*sin(angle2)
x=(yy1+rr1-(A/2+e1))*cos(angle2)
PUT x,y,-e2
NEXT angle2

I would code the arch into the niche (not rotated like you have it) and then use a tube or prism of some sort to fill the rest

than you,
Sides of niche are not perpendicular...

The sides of a niche don't have to be perpendicular.
They can be a prism so they will be perpendicular but they can also be a pyramidal or wedged where the sides won't be perpendicular.

I haven't played with it enough myself to tell you the actual settings - or if in deed it will actually work.

Remember if you can't do it with one wall niche you can combine 2 or more to get the shape you need.

@Barry, thank you for a tip. I try this, but in this type of niche_shape (arch) it doesn't work. maybe I overlooked something i don't know.
So i tried "SenecaDesignLLC" method (thank you again) with tube. (i hope this is the way) Unfortunately I have problem with tube geometry - it is deformed.

looks like you will have to extrude and cutform? no tube they are problematic

[SenecaDesignLLC]

if you find the right calculations for distance, the wall niche with method 2 gets you what you want

[rozky]

finally I find solution. Not nice but it works.
wallniche with method 1,A,B,....Subgroup with Prism A,B(prism interact with wall) and Ruled.
If someone have a time try to find smarter solution with this parameters.
Thank you all...
