I think about and teach that work flow thing. Order of operations is a good term for it, too. I can speak to drawing the sideboard because furniture is most of what I drew in SketchUp. I would use the same basic approach for drawing a house, too but I wouldn’t be surprised if others share different approaches.
So first, it depends upon the level of detail you’re after. Most of the time I’m drawing to joinery level for plans such as for this lowboy built by Philip C. Lowe.
I would start by drawing and placing the legs. Front left leg first, make it a component, Move/Copy and Flip along to make mirrored copies. In the case of the piece, I started with much simpler legs so I could quickly get the rest of the parts drawn. I wen back and shaped the legs later. Then I draw the rest of the parts to fit in between. If the legs are properly placed, and I draw the rest of the parts in situ between them, they have to be the right size. No joinery is drawn until after I have all of the parts drawn. Every part that would be made in the shop would be a component even if there’s only one of the part in the model. When there are mirrored parts such as the sides or the left and right vertical dividers between the bottom drawers, I draw one, make it a component and copy it to make the other making sure it gets flipped. The same applies for all the internal parts.
The only parts that get drawn separately are things like the drawer pulls, hinges and other hardware but I make those components to save and insert them when I’m ready for them. Setting the component axes and origin to a logical place in the component makes them basically a simple drop in place and leave them operation.
After I have all of the parts in the right locations and I’ve confirmed the dimensions I’ve got, I go back and detail the joinery. I’ll use various methods to reduce time spent so for example I’d get tenons drawn on the sides and use those tenons to cut the mortises in the legs or I’ll draw the dovetail pins on the drawer fronts and use them to cut the sockets on the drawer sides.
Hopefully that gives you some idea.
