At this stage however, a minimum understanding of control points is still necessary to use the tools. What this means in practice is that eventually the user will not need to know anything about control points, knot vectors, or weights. So when we dimension/constrain the handles, we are dimensioning the surface itself.

The main difference with subdivision surfaces being that with full NURBS, we can have perfect conics, no intrinsic continuity limits, and the ‘handles’ stay on the surface itself.

Ideally, the user interaction with the points/normals would be analogous to manipulating a coarse mesh, like subdivision surfaces. This is very personal, and cannot address all individual preferences. I have some ideas as to what constitutes an efficient and intuitive input/interface structure. The ultimate goal is to implement a set of tools that require very few points and tangents/normals to generate NURBS surfaces of high continuity. Moving the white lines of the sketch sculpts the blended surface. There is a fair amount of work to setup a blended model, but the payoff is that all the work is parametric, so one can go back and edit the initial overall sketch, and everything, including the blends will update. trim/clip sections of curves / surfaces (several steps needed here) convert the polygons to curves (black lines), or combine the polygons into grids (light blues lines) convert the sketches to polygons (blues lines) create and position sketches using FreeCAD (white lines) The next image shows the current required steps: It shows control of an overall shape with ‘main’ sketches, and automatic ‘blending’ of the corners of the main surfaces to obtain curvature continuity (G2). What does it do right now? Here is my favorite model so far. The sketches are used to control NURBS curves and surfaces. The workflow is based on sketches drawn in FreeCAD 0.17 or later. This is the rough workflow prototyping phase. My python scripts for creating surfaces in FreeCAD. View the Project on GitHub edwardvmills/NURBSlib_EVMĪLL DEVELOPMENT HAS MIGRATED TO SILK NURBSlib_EVM There is also the possibility to use a gratis service ( beside subscription of their newsletter) such as Netfabb.Python scripts and macros to make NURBS surfaces in FreeCAD. If all else fails, you can use another application to repair the object. stl object(s) and hopefully by using the ' Evaluate & Repair' can fixe those issues and get your slicer to happily accept the object. Activating the workbench in question, one can find a ' Analyze' submenu, after choosing your. stl's, there is an workbench called ' Mesh design' which can help you solve these hiatus. If your slicer complains about your newly exported. Choose ' Mesh formats' and finally ' filename.stl'. This can be by selecting those object(s) you want to export and then ' File -> Export' or by pressing ' CTRL+e'.

Gives you an idea just how easy it can be to build a object in FreeCAD. (See also old their respective export & import-threads.)

Experimental module for Export/import of CSG ( read OpenSCAD) since v.0.13, ( announcement-thread).

Such as the Free cellphone Neo Freerunner case files.

Export/import of different formats such as IGES & STEP ->.

It is also useful for amongst other things: There are several helpful resources just clicks away: That being said, there are a few bugs and remember saving your work! As always learning new things may seem daunting, but remember those dreams of yours and keep RepRap's philosophy close at heart! Good on it! Why limit one self, right?įreeCAD can definitely be a good starting point! Although FreeCAD is in development but it is quite useful even at this point. B.: These days FreeCAD can actually dabble with OpenSCAD.

FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties.
