Warning: If importing a DXF or DTM file where the distance units in
the source file are different than the distance units for the current
job, the imported coordinates will be converted to the current job’s
distance units when they are imported. This is normally the desired
result, but it can cause a problem if the distance units for the
imported data or the current job were set incorrectly. This situation
can most commonly occur when working with Feet and US Survey
Feet, where the conversion from one to the other is not always
obvious.

Usually the difference between Feet and US Survey Feet is negligible
(2 parts per million), but when dealing with State Plane or UTM
mapping plane coordinates, which are often very large in magnitude,
the difference can be substantial if the coordinates are converted from
one format to the other.

If importing coordinates from a source where you are not sure if the
units are in Feet or US Survey Feet into a job that is set to Feet or
US Survey Feet, you will usually just want to import them without
any conversion being performed. To do this, be sure to select the
same distance units for the source file as those set for the current job.

With C.L.

: When checked, offset and stationing information from

the selected centerline to the stake point is also provided in the DTM
Shot screen.

&KRRVH D &HQWHUOLQH« : will open the Select Line screen where an

existing polyline can be selected that describes the centerline.

Store Point

: is the starting point number if points are stored during

the staking process. Future points are stored with the next available
point names.

;

Generate TIN w\Staked Points

: will add any staked points to the

TIN so the shape of the DTM can be viewed at any time in the 3D
View screen and live cut / fill values can be viewed. When unchecked,
the 3D View is unavailable and cut / fill values cannot be viewed, but
are still stored to the raw data file.
