Drawing Issues

Whilst I can convert the data contained within a PDF to work within a CAD package the information contained within a PDF is not as reliable as CAD data in a DWG. Converting the data is taking the line image and converting it into useable data, however dimensions can vary greatly from what they are actually supposed to be. As such the group was working from the same drawings, but the information contained within them could vary between each group member. We decided to produce one set of CAD drawings that we could all work from. I modelled the building in 3D to ensure that the information I was reading would enable us to build the model correctly and that everything would work together and fit. Producing a 3D model allowed a 'dry run' at ironing out any problems with the drawing information and also ensured that all team members were working to one set of data and drawings.
