- By Hand: using the drawing and a triangular prism shaped scale ruler (shown below), multiple polygons are drawn and their sides measured using the appropriate scale to estimate the sum of their areas. The polygons are drawn as a mosaic that covers the entire area of the site that will be constructed with the material. Their areas will then be summed up to give a close estimation of the area of the constructed part of the site.
- By CAD: using the CAD drawing, curves, lines and points are marked on the area needed to be found and then using those points and lines as a reference, the software calculates the exact area the points and line cover over the drawing. the process using CAD is more accurate than by hand since it can incorporate curves as compared to the hand method in which only polygons are used.
I also visited a site with my mentor where a large warehouse is to be constructed and designed by Neglia. Pictures attached below:
