Ceiling or floor tile can be easily taken off using eTakeoff’s “Grid” extension. Grid extensions let you specify the size of the tile (GSHeight and GSWidth in the screen shot below). You can move or rotate the grid for the most efficient layout. The number of full (FullCnt) and partial (PartCnt) tiles are computed automatically. The tile layout is shown on the drawing. Partial tiles are shown with dotted lines. In the example below, dividing the area (1,413.33 sf) by the tile area (4 sf) would yield 354 tiles. But laying out the grid shows that 365 tiles are needed.
