When we talk about the drafting services, there are so many types of images formats are available which are useful for a variety of different software. For using directly scanned image for the CAD drafting, we need to convert the scan image into the CAD reading format image. If you are just starting out with 3d scanning, we will give a brief overview of the image conversions.
Before diving into the conversion tips, let’s have a look what are raster images and cad drafting image?
Whenever you scan or upload a document file to your computer, you get a raster image which is a mixed colourful and asymmetrical image. These kinds of images have multiple colour pixels because of which they look colourful. These images can be used for any purpose like printing, scanning and much more. But when it comes to the 3d cad models, the software needs a different format of the image, which is the CAD drafting file.
Vector files or the cad drafting files:
Vector files are the combination of instructions for drawing the lines, arcs, curves, and circles. These files are much software friendly as compared to the raster files. The two formats are very different from each other and for converting them from one format to another, certain challenges are present.
Here are some tips for converting the raster into vector files for executing your 3d cad drawing services properly and in an error-free manner. As these tips are very simple, you can use them easily even if you are a beginner.

1. Don’t scan in colour format:
Whenever you scan your any document or any drawing using, always make sure you are using a grayscale format. You can use any of the image editing software to convert your colour or black&white images into the grayscale format. The reason for doing this is that it will provide you with more control over the appearance of the image when you upload that file to the AutoCAD. You can also hire a 3d cad drafter on a contract which can get your work done easily if you are having bulk processes.
2. Use a proper image editing software for scanning:
For a flawless output, use an image editing r scanning software. You can use Adobe Photoshop because it comes with tons of other features also or you can use any of your favourite scanning software. By your scanning software, clean up all unnecessary grey shade or spotted areas in the file before you start the importing process for the AutoCAD.
3. Use de-speckle or de-spot feature:
Check it whether your scanning or image editing software is having a “de-spot” or “de-speckle” feature. These features will clean up your image with great precision and more perfection and ultimately it will reduce the raster image’s file size. And when the size is reduced, you can expect fast rendering and output process.
4. For fast performance, you need a fast machine:
If you are planning to import heavy raster files, you need to upgrade your computer faster processing and quick rendering. Otherwise, the process will take much more time. And if you are having a considerable amount of work, you can also hire a cad engineer on contract.
