Happy to have found this project, but questions

[ShamanTcler]

When I try a tenon I get something that has rounded ends, what if I wanted square ends? Something like a craftman style tenon?

Also I don't see the option for a "reveal". Think of it this way the rule of thirds ... so if you have a 5 unit (in or mm) face with a 1 unit reveal the thickness is 5- 2*1 or 3 ... does this make sense?

I have done a mortise and tenon joint using sketches and spreadsheets, but that was before finding your work.
