Can't make T-junction walls

I don’t know if this is a feature or a bug, but while designing my building, I consider of placing interior walls in my building, with a little door-less opening between two columns. At the moment, this can only be accomplished buy using free-standing walls tool…

However, I discover that you can’t hot-swap a part of a wall with a column or another placed one. Which means, I can’t make a T-junction wall! But, at least you can edit individual columns to mask it as a “wall,” but being a guy picky on placement (I can’t believe you can still select completed buildings), I can’t ignore the fact that disguised column is still selectable. But hey, is there no way to make easy interior walls?

Thank goodness you can now delete recently placed walls with the undo function or the console ever since I returned to playing this game.

(PS: Also, I discovered a “new building bug” whenever I tried to place slabs on columns. Another bug report to file then…)

Yeah, the building in this game is really strange right now. The team is working on redoing building, but until then, you can make a t-junction (sometimes) by using the intersection as the end point only. Start each wall at the other end. Doesn’t always work, but I think that’s the best that can be done until the building revamp is done.

Edit: Never mind, just tried it and it doesn’t seem to work anymore.
