Wall reference line in composite walls

[KeesW]

Here is something that most of you probably know but I didn't. Wall reference lines in composite walls are not infinitely adjustable, as for ordinary walls. In fact, there are only 6 options. Putting the centre of new walls over predetermined grid lines is sometimes a useful way to start a plan. I did so, selecting the centre of the wall for the wall reference lines because I hadn't resolved wall finish thicknesses. I figured that I could adjust the exact location of the reference line later.

NO! If you are using composite walls comprising a standard timber frame with different finishes, one should select the 'centre of core' option. If one doesn't do this, walls with different thickness claddings won't line up or join properly because the reference lines won't line up. I've had to go through and adjust all my external walls because they have thicker claddings than internal walls. A lesson learned for next time!

Not entirely true. While there are only certain default locations for the reference line, you can adjust it infinitely with the indicated reference line offset control. Typically I set my reference line at the structural core and allow the skins to do what they will and then adjust the few walls necessary for proper clean up.

Of course there may be more adjustment with a centerline alignment depending on your wall skins.
