Let’s use the attached simple gatehouse design with one 900mm x 2100mm door, a 1200mm x1200mm window and a 600mm x 600mm toilet window plus a 750mm x 2100mm toilet door. (I have done the elevation to ensure all possible elements are visible on the elevation).

OK – This is it.

Our 1st task would be to find the linear length of the entire building line i.e. how long is the block if we put them in a single line; we would achieve this easily by taking one grid-line after the other.

Grid 1 = The linear length of blocks on grid-1 is 4500mm (its that simple), now lets take for others.
Grid 2 = 4500mm also (now you’ll notice i omitted the windows and door opening on grid-2, we would come back to deduct those.
Grid A = 3000mm
Grid B = 3000mm
Grid C = 3000mm

Now, lets add to get the total linear length of building = (4500×2) + (3000×3) = 18,000mm [its important to group similar dimension especially when dealing with larger drawings to safe time].
