When dimensioning, in the options bar, we have the ability to prioritise our selection using the drop down menu. Our choices are; wall faces, wall centreline, faces of core, centre of core.
This is only a priority selection though, not an exclusive one. I wish in the options bar next to the drop menu you could check to make that an exclusive selection, that way, no matter where you hover your cursor over the wall, you can only select that choice.
I find it annoying that having chosen to dimension to 'face of core' that my cursor still picks up wall faces. When you have walls with layers of plasterboard and I am dimensioning setout, the layers of plasterboard are of no concern to me. It is the framing that I am interested in. I just think this would be a nice feature to improve productivity and reduce error. Less zooming & my middle mouse wheel would last longer too!
A trip to AUGI wish list is in order!
