Exciting times on the test layout.
The attached videos and pictures show a cast house in the works. Disregard the hot glue please. I like hot glue for checking fit because it doesn't magically find my skin like super glue does and it dries pretty fast. I usually get rid of strings with a blow torch but the cylinder is out of propane.
This experience went much the same as building the start of the open hearth: everything is not straight. I think the solution here is to try to use Plastruct columns instead of printing my own. It would help.
I also realized I failed to print holes into the cast floor for the iron to drop into the torpedo cars below. WHOOPS! I'll have to correct that on the next go around I suppose.
This model comes out 3/8" bigger than what I planned for in the track design but I don't think it will hurt anything. I'm actually much more concerned about the height. The test layout was moved away from the walls to allow for ceiling work to be done so those ducts won't play as much of an issue in the final layout but even still, it sure is close to the ceiling. The blast furnaces will only have the helix under them under the table. I'm considering dropping their elevation a bit. I like the fact that it will add to visual interest (the world isn't flat afterall 
) and it will reduce the grade for the high line and that will make the grade look more believable.
I am very pleased with the clearances. B6's, 0-8-0s or the little 0-6-0 docksiders will be working the blast furnaces (torpedo and slag cars). All three clear with just over a scale foot of room.
Hopefully these videos come out ok. They had sideways thumbnails but played upright on my computer.
The rest of the day will be spent rearranging more of the basement and cleaning the ceiling to prep it for paint.
EDIT: Yep. I filmed that with a vertical phone. Sorry! I'm new to the video stuff. I was focusing on trying to hold the phone still. I didn't consider portrait vs landscape
