RFMS cannot currently Estimate Mosaics set on a sheet. YOU WILL BE SHORT!
Heads up here.
If you are estimating tile set on a backing (mesh or paper usually) that comes in 12"x12" or wherever size sheets. RFMS will calculate ONLY the tile sizes and their area. as illustrated here:
As you can see I have a 2"x2" tile set on a 12"x12" sheet with a 1/2" grout line (i know thats big but its for illustration purposes to get an even 25tiles a sheet) set on a 5x5 shower pan.
The program then calculated the net area as 25sf. Thats right.
But then mistakenly says I need to order and charge for 16sf!
Because the program calculates tile area only.
It cannot understand that I purchase 2x2 tiles on 12x12 sheets (sold as 1sf/sheet) that have grout lines built into the sheet (and thus the area i need to order)
This calculation error has cost us money in mis-orders and was only caught today.
