The AEC Associates PDF to CAD conversion has now become an integral part of the daily routine of the construction industry, providing a starting platform to the designers for the future design process. Most professionals in the AEC industry require PDF to CAD conversion on a regular basis; thousands of online conversion companies have mushroomed all over the world to cater to their needs in the recent years. Let us talk briefly about the file types used in the process before discussing the complexities involved.
File types used in CAD conversion:
Two types of files are used in PDF to CAD conversion: PDF files and CAD files (DWG or DXF).
PDF, developed by Adobe systems, is a most accessible file format and can be easily accessed almost anywhere since PDF reader is pre-installed in virtually every machine. PDF files may contain several pages, each page exactly as it would look in print.
DWG or DXF files are used by almost all the modern CAD software all around the globe. They can store heavy 2D and 3D design data with all the possible details.
Reason for PDF to CAD conversion:
There are basically two reasons for PDF to CAD conversion.
- DWG files contain quite heavy data; it often becomes difficult to email them. They are converted into the lighter PDF files for emailing purposes. These files are later reconverted into CAD files for easy viewing and editing.
- Just like erstwhile ammonia or blue prints, professionals issue the drawings in PDF format as they cannot be edited or tampered with. This way they can protect their professional interests.
Even though CAD conversion has become a common process, it is by no means easy or simple. On the contrary, it has many complexities involved and requires expert handling for good end result.
- Vector PDF files contain no CAD arc or circle entities, these arcs and circles have to be made either out of many short lines or Bezier curves if top-quality software is not used and the resultant drawings may be of poor quality.
- Similarly, words and sentences are held in PDF files as a set of individual characters, each set with associated positional and style information. Only good quality software and skilled persons can ensure exact reproduction of text in the converted files that would otherwise become illegible or distorted.
PDF to CAD conversion is a complex process that needs good software and skilled professionals to ensure excellent converted drawings. If the drawings provided to the designers are of top-quality, the future design process will start on a positive note.
