5 Best Free OBJ to DXF Converter Software for Windows

Here is a list of Best Free OBJ to DXF Converter Software for Windows. Using these free software, you can convert a 3D model present in OBJ file format (developed by Wavefront technologies) to AutoCAD DXF format (Drawing Exchange Format). You can also convert OBJ models to some more 3D file formats in these software, such as DWG, PLY, STL, DAE, 3DS, etc. These also let you convert 3D OBJ models to various image formats like PNG, JPG, GIF, BMP, TIFF, etc.

The advantage of these converters is that you can also modify the input OBJ model before converting it by using various model designing tools. These 3D tools include mesh design tools, insert various 2D and 3D shapes, text tool, rotate, flip, move, extrude tool, and more. These also contain a handy set of 3D model viewing tools which include pan, move, rotate, change rendering mode, change view, adjust camera settings, animation, etc. With these tools, you can easily view and analyze OBJ and other 3D models before starting the conversion.

In general, these are quite powerful and feature-rich software that can also be used for the conversion of OBJ to DXF and other file formats.

• Now, you can simply view and modify source 3D model as per your requirement.
• Next, go to its Model icon and click the Export as 3D > DWG/ DXF option and select DXF as output format to convert OBJ to DXF.

Limitation:

It can be used for free for private use only.

Conclusion:

It is a good 3D modeling software that you can use for the conversion of an OBJ model to DXF format.

MeshLab

MeshLab is a free open source OBJ to DXF converter software for Windows, Mac, and Linux. It is a standard 3D modeling software that comes with an additional conversion feature. You can simply open and view an OBJ model and then convert it to DXF or any other 3D file format, e.g., 3DS, PLY, DAE, X3D, etc.

Prior to conversion, it also lets you modify source OBJ model with the help of its 3D modeling tools. These tools include translate, rotate, scale, align tool, painting options, edit referencing, etc. It also comes with various handy filters to apply over input 3D model such as point set, sampling, texture, cleaning and repairing, remeshing, simplification and reconstruction, color creation and processing, quality measures and computations, etc.

How to convert OBJ to DXF in MeshLab:

• Open an OBJ model in this software using File > Import Mesh option.
• View and edit imported OBJ model.’
• Convert OBJ to DXF using its File > Export Mesh As option.

Conclusion:

NuGraf

NuGraf is yet another OBJ to DXF converter software for Windows. It lets you convert one or multiple OBJ models to DXF and other file formats including DWG, STL, PLY, SLDASM, IGES, DWF, 3DS, STP, etc. In case you want to view and analyze imported OBJ model before conversion, you can use its import and export functions.

How to convert one or more OBJ to DXF in NuGraf:

• Firstly, open its Batch Convert tool from the File menu.
• Now, add one or multiple source OBJ files to this software that you want to convert.
• Next, select output format as DXF R12 and configure output parameters including output polygon, separate polygon into separate layers, output enables (polygons, 3D point set, polylines, etc.), line terminator type, etc.
• Finally, set output location and then hit the Convert Files! option to batch convert OBJ to DXF.

Limitation:

This free version of NuGraf doesn’t convert every 5th polygon of each object in output.

Conclusion:
