Datum Setup

Datum Setup

Details

This is a core settings control to establish the initial Datum's used for the long section display.

The Datum controls include two parts, each listed as SEPARATE items in the data list:

Datum Settings - establishes the overall layer control, persistent prefix/suffix text as well as the rounding of the datum text;

Row/Band Item - position this where you want the datum to be calculated from as well as establishing the height of the row. The Heading controls applied here also establish the Prefix text information displayed for the first datum on each sheet. This row will automatically be created and users are strongly encouraged to edit the details of the band as well as the position.

Using this command will automatically create both data entries.

Rounding (m) In the box provided enter a rounding, in metres, for the Datum level to snap to.

Datum Settings Entry Form is as above. This controls the rounding of the datum and general datum controls.

Structure Item (Datum property) This entry is a Row/Band that exists in the Bottom of the bands/rows. Position this where you want the Datum to be measured from in the bands. This will act as a band in the long section. Use the HEADING LINE 1 control to establish an additional text Prefix to be applied to the first long section branch displayed on each sheet

Structure Row/Band Item Added for the Datum

It is critical that users understand that the Structure item controls the position of the Datum on the long section. The Datum will take up a band of information in the plot. Edit the datum band to confirm the details:

Users should edit the Heading to control how the Datum is represented on the first long section of each sheet. The Linework and Text tabs can be used to control the band height and text.

Inputs are as per the Structure Items command control.
