I have worked for 30 years designing and drawing buildings from houses, to factories,
hospitals to apartment high risers. Now I prefer to measure existing buildings especially
of the kind that have historical value so that it can be published in CAD format. I can
work from PDF's and give the drawings out in .dxf files. Recently I have measured one of Cape Town's oldest buildings and produced that in CAD drawings. The orginal building plans were lost on this building and the latest drawings were inacurate, hence it was difficult to plan
any work that the developers had in mind. I prefer to measure up in Cape Town and will do
drawings from other documents in any other place.
