A few tutorials show that it is possible to get Blender, the open source sculpting and animation tool, up and running on the Pi 3. Surely there are other programs that could help to round out the tool kit. Rather than troubleshooting to make it work I prefer to jump over onto a mac or PC with native Chrome or Firefox where the in browser design experience is still much more stable. At this point it seems to be a limitation on the support for the Chromium browser, which is just getting started in WebGL with some of the more recent builds. I am sure too that over time Onshape will start to become an option. TinkerCAD offers a similar in browser design tool and though the functionality is not the best it is plenty to get something started. There are also other online tools, like the easle app by instructables, that can be used through a chromium browser. Most major CAD programs will accept the incoming design files and for CNC or 3D printer control there are file conversion tools that are relatively easy to access.Ĭoupled with OctoPi, or some CNC control projects, the possibility of driving useful prototyping and manufacturing tools from a Pi really start to open up. dxf which can be used by AutoCAD or imported into Solidworks or Onshape. The file types are limited for saving, the default format is. Tracing the print is a good way to get practice in the sketching and drafting tools function.
Importing an image can be done from the left side menu. To get things started a simple template helps to provide some context. That is not a real surprise given that the graphics are so bare, but even it did strike me that the CPU usage was a fraction of what the system uses to run even the barest of webpages in a browser. Surprisingly there is very little CPU or GPU usage while running the LibreCAD software. Still for CNC work or even layer profiles of 3D printing this is fine. The UI for LibreCAD is very similar to other 2D drafting packages, that is to say it could use some updating.
#LIBRECAD DWG SOFTWARE#
Within minutes I was able to pull up the software and begin sketching. It is open source, lacks a little in the UI, but is a fairly intuitive drafting tool.
#LIBRECAD DWG INSTALL#
One of the more accessible CAD programs, from an install and setup standpoint, is LibreCAD. With a few CNC projects out there opportunities for making use of 2D CAD data exist. The attempts at Onshape on a raspberry pi failed but there are native linux cad tools available.
