The description is fixed as the station and offset, but can be edited using the command Keyboard Input or File, Points.

The "Interval" option is not typically applied, unless Store Multiple is selected, in which case points will be stored

sequentially at the entered offset from the starting station to the ending station as entered. In addition to calculating a

station and offset perpendicular left and right, skewed pipes can be calculated by selecting the "skew back" or "skew

ahead" options in the pulldown list where "offset" is the default. A zero skew pipe is perpendicular to the horizontal

alignment. So a "skew ahead" of 20 degrees would be 20 degrees "ahead" of the 90 degree offset, or 70 degrees to the

right of the forward tangent. Here is an example where both ends of a pipe are calculated, with the resulting graphic

shown below. Decimal places on the stationing are set under File, Job Settings, Format Tab, Station Display.
