Edit: I've confirmed this is a bug in X16, it's working fine in X15. I've created Support Ticket 133553.
I'm still learning. Following both https://cloud.chiefarchitect.com/1/pdf/documentation/chief-architect-x16-reference-manual.pdf (Page 861) and from 3:00 of this video: Using the Gable-Roof Line Tool - Video | Chief Architect I can't get the alcove tool to work in X16.
Using a default new/template, with zero changes, and drawing exterior walls roughly the same as the video above. I can't get it to cover the alcove. What am I doing wrong? Attached video of my attempt to close the alcove.
