The images were drawn in the computer into some particular formats like GIF, JPG, JPEG, PDF etc. Images in these formats are called raster images but they have some limitations. These limitations include the need to edit the image, increasing the resolution, creating different layers of the same image so that everything can be explained in separate layer etc.
As the time passed, a need to remove these limitations occurred and a new technology called Computer Aided Drafting (CAD) came to rescue. CAD technology helped to convert these raster images into vector images i.e. into DWG format which is the native of this technology. This format allowed to overcome these limitations and to take those pictures into new arena where they could enjoy the benefits of new technology. The benefits that can be availed through format conversion are:
Desired Changes Can Be Made
When it comes to make changes, raster format does not allow making any changes in the image. If it is required then the whole drawing has to be made again. This limitation created a requirement to get a technology which let the user to edit the drawing when it is required without having to redraw the whole picture.
Creating Many Layers of Same Drawing
Now, the drawings can be seen into different layers. These layers allow one to view different features of the drawings separately. For instance, the text and drawings can be seen separately. If the blue print of the building is drawn then the electric fixtures, plumbing fixtures, doors and windows could be seen into different layers to understand the blueprint in better way.
Resolution can be increased as required
One more problem was being faced by people with the raster format is that the resolution of the pictures could not be increased, since they went blurred when the resolution was increased. It translates into that every nook and cranny of more complex drawings could not be seen, as this could help to demonstrate the image in better way. But, DWG format helps to avoid this problem.
Files are easy to keep safe for longer duration
Files in DWG format require less space as compared to GIF and therefore, they can be kept safe easily and that too for longer duration. Moreover, this helps them to transport easily through internet from one computer to another. Otherwise, heavy files cannot be downloaded or uploaded easily on internet.
All these developed features of DWG format create a necessity to convert GIF files into DWG files. Those who want to take the benefits of new technology will surely give a second though to the format conversion of their existing files.
