If you work with AutoCAD you have probably had a regular requirement to convert an image to an AutoCAD format. The problem is that many conversion solutions will not give you the results you require. In this post we’ll discuss how you can accurately convert your images to DXF or DWG saving you from manually tracing your designs.

Let’s begin with a demonstration of how professional conversion software, Scan2CAD, can convert an image to an AutoCAD format.

Image/jpeg: application/acad, application/x-acad, image/x-dwg: Developed by: Joint Photographic Experts Group: Autodesk: Type of format: lossy image format: Computer-aided design: Description: JPG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. This is done forever with the AutoCAD program and is therefore very important to convert image to Cad. To convert images to CAD format, is to say add vector image, we could do it in different ways, for example from a website (something that is very disastrous, as always seems to end badly), another option would be to acquire software conversion (an unnecessary expense because they can only.

What are your options when converting an image to AutoCAD?

What types of images can you convert your AutoCAD?

To answer that question, we should first get specific; in this post we’re focussing on converting raster images to an AutoCAD format (i.e. DXF or DWG). A raster image is an image formed of pixels such as JPG, BMP, TIF and many more file types.

Raster images are different to vector images. Vector images (such as vector PDF files) are typically much easier to convert to an AutoCAD format because DXF and DWG are also vector file types. The technical term for converting raster images to DXF/DWG is ‘raster to vector conversion’.

Scan2CAD supports all the raster and vector image formats you would come across including JPG, BMP, TIF, DXF, DWG as well as raster and vector PDF files.

What are your options when converting an image to AutoCAD?

When you need to convert an image to AutoCAD you have three options:

Convert using Raster Design
Convert with conversion software

Option 1: Manually trace the image

If you opt to manually trace a drawing you will commit yourself to a long painstaking process of drawing over each individual element in your image. It’s surprising that many people are still manually tracing raster images when automatic conversion software could save them countless hours and therefore budget.

Some AutoCAD users may prefer to manually trace an image because they believe that it is not possible to achieve a high degree of accuracy with conversion software. This is due to the vast difference in conversion accuracy offered by the conversion software available (most notably, the poor results provided by online converters). In almost all cases, the far better option is to automatically convert your image to AutoCAD format and then manually edit the file to get that final 1% accuracy if required.

Option 2: AutoDesk’s Raster Design

Raster Design is Autodesk’s solution for automatically converting a raster image for AutoCAD.
Unfortunately Raster Design is not AutoDesk’s core product and it doesn’t offer much of the required functionality to produce useful converted images, therefore a significant amount of manual input is still required.
Raster Design utilises simplistic vectorization methods which are not designed to convert each image element to their correct vector CAD entity. Instead, all elements will be represented as lines or polylines.

Raster Design may be commonly used by AutoCAD users due to the fact that it is part of the AutoDesk product offering. Therefore there is little friction in trying Raster Design’s conversion results first before finding that better results can be achieved with another solution.

Option 3: Convert with conversion software

Using Scan2CAD to convert text and other elements in an image

Scan2CAD is raster and vector conversion software designed specifically for CAD & CAM. We have spent the last 20 years focussed purely on improving the conversion performance, saving time and money for the world’s design, manufacturing and AEC companies.
If you need to convert an image to AutoCAD format you will most likely find that Scan2CAD will offer the best performance in almost any circumstance.

Unlike Raster Design, Scan2CAD is a standalone application which doesn’t need to be ran as a plugin to other CAD software. Scan2CAD offers OCR and object recognition which means you will convert image entities (including text) to the correct vector CAD data.

Why do some converters create poor quality results?

Scan2CAD converts a circle to a vector circle entity, not a collection of lines

The worst type of image conversion would be to convert every object in your image to the same vector element. For example some vectorization software might convert a circle in an image to thousands of small vector lines or polylines instead of a single CAD circle entity.

With this type of simplified vectorization software; the text, arcs, circles and all other elements would be represented as many individual connected vector lines. But that is practically useless if you need to edit the CAD drawing in AutoCAD.

This is why you need conversion software which has object recognition capabilities. What is object recognition? It is the process of identifying entities (objects) in your raster image and converting them to the correct vector CAD entity.

What if the image contains text?

If your drawing contains text you will need to ensure that your conversion software has OCR capabilities. OCR (optical character recognition) converts text in your image to editable vector text strings, identical to the text strings you would create when writing text in AutoCAD.

If your conversion software does not have an OCR feature, the software will instead convert all the text in your image to a collection of vector lines or polylines. We call this ‘exploded text’ but it is not really text at-all, it is simply vectors in the shape of text.

Text converted to text strings using OCR

The ‘exploded text’ can not be edited in CAD software so you will need to erase these vectors and redraw the text in AutoCAD.

Conclusion – How to convert an image to AutoCAD

If you need to convert an image for AutoCAD we recommend that you choose software designed specifically for that purpose.
Scan2CAD offers the most accurate conversions of your raster and vector designs. With automatic conversion software you will save countless hours spent fixing poor quality conversions or manually tracing files.
