Grid Extension

This document describes grid extensions. Grid extensions have all the functionality of normal (formula) extensions, plus they calculate and display a grid of squares covering the measurement. Grids are typically used to lay out floor tiles or ceiling tiles but they can be used for any rectangular layout. The following parameters can be specified for a grid extension:

The full grid squares are surrounded with a thin solid line. The partial grid squares are surrounded with a dotted line.

Creating Standard Grid Extensions

If no standard grid extensions exist, you can create a grid extension using Standard Extension Maintenance. Simply press the "Add" button in the Standard Extension List Window and select "Grid" from the context menu. The Standard Extension will be displayed with five rows predefined.

The five pre-defined rows are:

The name and position of the predefined rows can't be changed. Otherwise, the information can be edited as described for Standard Extension Maintenance.

Other rows can be added after the predefined rows. These rows can use formulas with any of the measurement values (Area, Count, Length, Perimeter) or the predefined rows (GSHeight, GSWidth, GSGap and GSEdgePcnt) or any of the following calculated values:

Editing a Measurement's Grid Information

The formula part of a grid extension can be edited the same way as other extensions. This is described in Extension Measurement Maintenance. You can also move and rotate the grid. To start this, right click on the measurement and select "Edit Extension" from the context menu. Then select "Move/Rotate Layout..." from the sub-menu. The Move/Rotate Toolbar will be displayed over the measurement as shown in figure 2.

The toolbar has four buttons:
