Yep, that's what I've been doing, but maybe I'm just being lazy or too demanding of a free product. Suppose I should better describe what I'm after, as some different form of the dim that is typed that interprets what is typed as the resulting dim (automatically taking into account the dim that was previously created possibly by another push/pull operation) rather than the dim for this push/pull operation alone. I am trying to avoid having to do calculations myself, lazy sod that I am. Hope this makes sense. I have at times first tried push/pulling down to virtually nothing (just before the whole face disappears into nothingness) which makes the calculation simpler and then push/pulling to the required length.

I like your "Benjamin Chair" very muchly by the way... guessing you CNC'ed the ply cross sections before clamping, gluing, and bolting through?
