This is because JPGs don’t save these drawings in black and white, but as grayscale images, with blocks of pixels in varying shades of gray.
This is an even greater problem for images which could be 2 color (black and white) for example, line drawings for part schematics, or architectural floor plans. The downside, however, is that JPG images are usually very distorted when zoomed in. JPG is a compressed file format, which means that some information is discarded in the interest of saving file space. It’s difficult to extract a clean vector from a pixelated imageĪlthough JPG is one of the most popular image file formats around, it’s not always ideal for conversion to vector formats such as DXF. This problem is compounded by the fact that DXFs don’t define physical dimensions using measurements like millimetres or inches. PDFs only preserve the relationship between objects (e.g. The trouble with this approach is that PDFs only store print dimensions, and discard the scaling information from CAD software. As PDFs can be opened universally, images saved under proprietary CAD file types are often converted to PDF before going on to be converted to DXF. One of the most common uses of Scan2CAD is conversion from PDF to DXF. The first thing to consider is which type of file you converted to DXF. “I’ve lost the scale information after converting my file to DXF” To help you tackle them, we’ve put together this list of some of the most common mistakes made during the conversion process – and what you can do to avoid them.
Sometimes, though, you may run into a few problems. In most cases, just following our quick guide to converting an image to DXF should get the job done. After all, the CAD/CNC file you require should only be a few mouse clicks away. When it comes to DXF conversion, you want it to be as quick and painless as possible.
