Hello Stefan and Sekar!
We were just working on a drawing set for kitchen production drawings earlier this week. Keep in mind a plan drawing must be a horizontal cut, and sections and elevations must be vertical cuts.
You found the Detail drawing! This is a lingering part of DRAFT mode that we have chosen to eliminate. It gives a 2d CAD drafting feel inside of SketchUp, then stacks viewports with lineweights that correspond to layer/tag color. I find the scaled drawing command in LayOut to be infinitely better, so we have eliminated this feature. It works… okay… not my proudest feature! But it served a purpose in the early days…
Can you clarify what is not working with your plan?
