This is usually very straightforward, both provide installers for many platforms or are usually included in the software repositories of most Linux distributions. Installationīefore being able to use the Raytracing Workbench in FreeCAD, one of these two rendering applications needs to be installed on your system. The best way to know is to look at examples on both engines websites. Both have their strengths and weaknesses, depending on the type of image one wants to render. POV-Ray is a very old project, and is considered a classical raytracing engine, while Luxrender is much newer, and is categorized as an unbiased renderer. Through its Raytracing Workbench, FreeCAD can use two of these rendering tools: POV-Ray and Luxrender. Some other open-source rendering tools are made to be used inside another application, and will take care of doing the complex calculations to produce realistic images. 3D models can very easily and faithfully be exported from FreeCAD and imported into Blender, where you can add realistic materials and illumination, and produce the final images or even animations. Probably the most famous one is Blender, which is very popular and widely used in the movies and gaming industries. FreeCAD being an application more geared towards technical modeling, it doesn't feature any advanced rendering tool.įortunately, the opens-source world offers many applications to produce realistic images. Of course, producing such photo-realistic images requires a lot of work, and a 3D application that offers specific tools for that, such as precise controls for materials and lighting. But anybody who saw a recent Hollywood movie knows that it is possible to produce images with a computer that are almost undistinguishable from a photograph. Of course, we could say that what se see in the FreeCAD 3D view is already nice. Online 3D design tools (onshape) are also available.In computer talk, a rendering is a word used to describe a nice image produced from a 3D model. At present, many 3D rendering tools are very mature (Auto CAD, CAXA, SolidWorks, etc.) or open source free (FreeCAD, LibreCAD). Q:Will EasyEDA support to draw 3D models in the future?Ī:Don’t. This format is more complicated and needs time to study. Q:Can EasyEDA export the whole PCB 3D format for structural design? Step, etc.Ī:It will be supported in the future, step by step, and will directly support importing the step format in the future. At present, you need to specify to PCB or PCB footprint. Q:Can the official footprint library specify the 3D model first?Ī:Yes, later official libraries will specify 3D models. Right click can edit and delete 3D library Switch to “PCB 3D library” and “WorkSpace” The SHIFT+F shortcut opens the component library dialog box For the specific use of the tutorial, please see: PCB - 3D Model ManagerĪdjust the position and parameter relationship between the 3D model and PCB packaging, and click updateĪfter completing all the specified 3D models, you can start the 3D preview of the whole PCB. Specify the imported 3D model for the corresponding footprint, which is basically consistent with the footprint manager operation.Open the PCB or Footprint, and find “ - Tools - 3D Model Manager”.You can check which 3D model you want to import. If your WRL file cannot import directly, please use FreeCAD to export a new one and try again. OBJ format contains many 3D models in one file, you don’t need to zip them. If you have many 3D libraries, you can zip them to a zip file to import, no more than 10 WRL files for one zip file, otherwise it will fail to import. (“mtl” files are automatically downloaded when obj files are downloaded.) Note that file suffixes cannot be capitalized. Other formats of 3D files wii be supported in the future. WRL can be imported directly without the need for compression Obj must be compressed into a zip file with the “mtl” file and then imported, and the “mtl” file is usually taken with you when you download the obj file. Note: currently only 3D models in “WRL(VRML)” and “obj” are supported. Exporting PCB 3D model files is not supported yet. EasyEDA supports for importing 3D models, PCB can view cool 3D models when doing 3D preview.
