It is often necessary to insert new cells into an existing grid. Grid+ allows individual cells to be added, or multiple cells as described below.
Insert a single cell
To insert a grid cell next to an existing cell, select two grid nodes of the existing cell (RMC on a node, hold the Shift key then LMC on the second node, the segment will be highlighted) then RMC to display options, select Line Mirror option as shown in Figure 1. As a result, a cell will be added that shares a grid line with the existing cell as shown in Figure 2.
Figure 1 Define where to insert a cell.
Figure 2 A cell is added to the grid.
Insert multiple cells
The method to insert multiple cells is similar to inserting a single cell, the difference is in the selected grid line. In this case, we select a longer grid line that contains many cell sides in the same line by LMC on the first node then hold Shift and LMC on the second node (Figure 3), then RMC to display options, and then select the Line Mirror option. As a result, a number of cells will be added as shown in Figure 4.
