Tori is how I spell the plural of torus.

It's also (IIRC) the first name of a female musician a friend of mine has 
a certain attraction for (Tori Amos)

Create a torus.

Rotate x=90 (type 90 into the x rotation box in the modify tab)

Translate z=5

Create a Cube.

Scale x=3 and z=2

Translate z=7

Create a CSG (union because all CSG operations start as unions in Moray)

Click Add in the Modify tab.

Add the Torus and Cube.

Select intersection as the Operation type.

Hit evaluate.

Create a cylinder.

Scale it to x=0.5 y=0.5 z=5

Translate it to x=1.5

Make another cylinder

Scale it the same as the last one.

Translate it to x=-1.5

Create another Union, and add the previous union and the two cylinders to 
it.

Leave the operation type as Union.

Now, if you select the union, you can move the entire (rather crude) 
doorframe around your scene.

Did this make any sense?

Sorry for the delay, but I tend to check my news once a day and read it 
offline, then I just drop on quickly to upload any posts.

Bye for now,
