**Scenario:**Most of my drawings are either architectural or construction and they have to be in imperial units. Futhermore they have to be expressed in terms of feet and inches as opposed to feet and decimal fractions of a foot. For example: people I work with are incapable intuitively understanding that 15'3" is the same thing as 15.25'.

**Problem:**I use the "snap to grid" feature pretty heavily to ensure my drawings are accurate. However, the dynamic grid zoom seems to work only on base 10. For example: I am currently looking at a worksheet where the grid is represented as : 0", 10",1'8", 2'6",3'4",4'2",5'0" ... and so on. In order to ensure my lines snap to the appropriate grid line I end up having to zoom way to finish a line.

**Question:**Is there a way to have the grid to zoom as whole increments of feet and then when it starts to zoom in to inches have the grid switch over to base 12: For example, as I progresively zoom in the first grid increment would be 6", zooming in my grid increment would be 3", zooming in further would give me a grid increment of 1". Similarly if I zoom out from the starting position where my grid increment is in single feet, the next increment up is 5', for example, and etc.. Right now, where I have to capture drawings with dimmensions as large as 100-200' I have to zoom down to the fractions of an inch just to snap to 178', for example.

Any help would be appreciated. Thanks.
