I didn't revert the order of the layers, but i was able to use the eyedropper tool to copy the layer order from one viewport to another. here are the options I used.

the other thing I would look for is a wall that has no fill. that makes it hard to find the wall when you drag along the wall.

sure, Bob, you can do that. Be careful of the inserting point of the symbol, it determines the elevation of the symbol when you use send to surface.

Edit your Massing model preferences. The important settings are the: use Custom Roof from Profile Pitched roof. You need both. once you have created your massing model, right-click and choose Edit Profile. The profile is a roof object that you can edit like a standard roof. The buildings in the image are massing models, even the one with the curve on the roof

did you read this manual? http://learn.archoncad.com/2018/07/31959/sst_1807-creating-and-managing-details/

that could be good, but it has its issues. people might use that to create openings in the wall, when they should really create an opening.

if you remove the 2D part from the symbol you can rotate it freely.

I think Boh is right with this.

are all your classes turned on? class options set to Show/Snap/Modifiy others?

if you use the second mode it works as you want.

Drag them by their number

I had forgotten that I had presented that webinar. For the changes to 2019, look at the Novedge webinar 300 https://youtu.be/L-whw7Z2_NU you can see an introduction to the changes for 2019 about the 1:02 mark

Do you want to send me the file?

try this: =INT(C3)+(IF((3)-INT(C3)>0, 1, 0))

you only need to add one if the rounding does work. I use this IF statement =INT(D3/E3)+(IF((D3/E3)-INT(D3/E3)>0, 1, 0)) (this is from one of my other worjsheets and does not relate to your worksheet)
