With most shade sail projects, due to the use of adjustable tensioners, there is some degree of tolerance with regard to measuring, design and manufacturing precision. We had no such luxury on this project.
The fixing points at each pole needed to be precisely located to ensure they lined up and wrapped snugly around each of the 8 poles, and allowed the sail to be tensioned up without touching the poles.
Complicating matters was the corner that the sail needed to turn – whilst a 90 degree corner, the projection of each of the balconies is different, so great care needed to be taken design to ensure the corner tensioned out nicely.
A precise 3-dimensional survey of the site was required to ensure proper fit. We used our Proliner 3D measuring machine to take all necessary dimensions and locations. The 3-dimensional measurements the Proliner provides are invaluable and time-saving as there is no need to spend time trying to work out how dimensions relate to one-another in 3 dimensional space.
In CAD, we loaded in the measurements from the Proliner and designed the sail. A great deal of thought and effort was put into ensuring that the sail could be manufactured with extreme precision that we had taken the dimensions. We achieved this by placing a series of alignment and dimensional check-marks in the plot output. Joining welds widths were adjusted as necessary, even if just by 1mm. This prevented cascading and compounding inaccuracies.
