How do I save the "view to cad"?

They don't stop changing their minds till the house is sold..
When building a house I snap all the lines on the floor with red caulk(last forever)so they can see where walls will be.
Even then,I tack the plates down and ask 1 more time if they like it before building the inside partitions..
So maybe "last" is when the people are moving in,just before the remodeling starts..
