Converting DWG Files via Command-Line

Convert dwg via cmd

Are you designing a program targeting people who work in architecture, construction engineering or design? If so, you probably want to add DWG conversion as one of its useful features. DWG (“Drawing”) is one of the most helpful and popular formats in handling computer-aided design or drafting (CAD).

However, though preferred by many for its ability to edit and optimize 3D design data and metadata, DWG files also have a few drawbacks. Firstly, in order to open them you need to have AutoCAD or IntelliCAD installed, and using these programs requires not only a powerful computer, but also special training. Secondly, DWG files tend to have very large sizes and require long loading times. For all these reasons, most people who work with DWGs prefer to be able to convert them into PDFs, because thus it becomes much easier to store, open and e-mail them.

3 Tips for Integrating TIF Conversion in your Custom Solution


The TIF (Tagged Image File) format is often preferred by photographers because of the image quality it provides, as well as its compression features and availability for editing. TIFs provide high colour-depth images and smaller processing times than, for example, EPS or AI files. Apart from photography, the TIF format is also used in the professional printing or publishing industry and in graphic art.

As opposed to JPEGs, which provide a “lossy compression” of the image, TIF files can ensure a “lossless” compression, thus retaining all the image details with increased accuracy. This, however, also means that uncompressed TIF files tend to get very large and are more difficult to store or share.
