Two file formats involved in The AEC Associates PDF to CAD Conversion are CAD (DWG or DXF) and PDF; the process has assumed a great significance for the building industry in recent years. Nearly all the top CAD programs use DWG (or DXF) files for storing large and complex 2D and 3D design data in an efficient manner. Despite being a versatile and complete file format for design and drafting purposes, DWG files can become very large and heavy at times and need to be converted into PDF files to reduce their size and also protect the professional and financial interests of architects. PDF to CAD conversion process is later necessary to reconvert the drawings into DWG format for easy viewing and editing.
Qualities of PDF file format
