Making sure about the dimensions of your objects.The Part Workbench also contains a Check Geometry tool that is handy to check further for possible defects.
We saw in earlier chapters that FreeCAD helps you a lot in that regard, and that the PartDesign Workbench will notify you if you do an operation that prevents your model to stay solid. Real-world objects are solid, the 3D model must be solid too. If you have been cautious while modeling, most of the difficulty you might encounter when printing your model in 3D has already been avoided. This chapter will show you how to get your models ready to send to these machines. These can be designed in FreeCAD, and then made real in different ways, such as communicated to other people who will then build them, or, more and more frequently, sent directly to a 3D printer or a CNC mill. One of the main uses of FreeCAD is to produce real-world objects.
