Technical Drawing

In order to create the set model, a technical drawing of the theatre would need to be drawn at a 1:25 scale. After being given the technical drawings for Theatre Royal in Margate, I started to work out the scale for the two technical drawings given.
One measurement was given on the drawing: 8235mm. This measurement would help me work out the scale factor of the drawing.

• Actual dimension (8235mm) divided by measurement from the drawing (72mm) = Scale factor of drawing (114.375) Scale factor is 1:114

To work out the rest of the measurements:

• Measurement from drawing multiplied by scale factor (114) = Actual measurement

All of the actual measurements then need to be converted to a 1:25 scale, therefore:

• Actual measurement divided by 25 = Measurement at 1:25 scale

I have found working from these technical drawings (especially the plan view one) quite difficult and unclear. The technical drawing showing the proscenium arch has part of it missing, which makes it harder to work from.
