5.
Similar to the stakeout of individual points in the toolbox. The Box/
Base functionality calculates the new point to stake out and changes
the values of Stake chainage and Offset.

accessing the box/base menu, press Base in the Box/Base Definition
panel. The values of the base point freeze when pressing the key.
Base is now replaced by Clear. If a different base had been defined
before, use Define to overwrite the values before pressing Base.
7.
Define the Distance box and Offset box. Both follow the same
rules as used for the definition of offsets and chainages in general.
Offset to the right = positive; distance in direction of increasing
chainage = positive.
