draw linear polygons with a fixed width and length divisible by 4 feet

[ChrisFox2]

I would like to draw polygons that are constrained such that they are no wider than 16 feet and the length is divisible by 4. 

I am  working on a project which requires laying down panels for equipment to drive on that are 4 feet by 16 feet.  What I would like to do is be able to easily draw areas that will represent these panels and be divisible by the area of one panel.  ie. I draw a line and I can easily calculate the number and area of the panels.  I have tried buffering a line then calculating the numbers I need but this requires too many steps and I only have arc editor so I can't create flat ended buffers. 

Any way this can be done by topology etc?

Have a look of the Create Fishnet tool (Data Management toolbox - Feature Class toolset):

Hope it does what you need to do.

i figured out that I can use strip index with no overlap and the window dimensions meeting my specs
