FreeCAD 1.0 Create Manual Fillet Using Blend Surface.

Great. Works perfect. Thank you very much. I try your recommmendaton for the bottle. Thank you 🙂

Great video!

Good morning! Is it possible to do a tutorial about car class-a surfacing with freecad? It will be a great video. I'm try to shift all my work flow, as mech engineer, on open source software suite. Thanks a lot for your attention and your works on this fantastic channel.

short answer no - FreeCAD does not have the tools you need for Class-A surf. The ability to move CVs is missing as well as crucial tools like the loft or blend surface tool giving it a topology align option etc. FreeCAD is far behind Rhino and that already is hard to use for Class-A. I also feel after few tests that the FreeCAD openCascade powered modeling tools in FreeCAD produce rather poor surface qualities. G1 seems doable but G2 it seems is borderline unusable. I could be wrong - however all FreeCAD models I opened in Alias showed a shocking NURBS patch topology. Even in Fusion360 this is an extremely difficult task

Example: Sketch, pad the rectangle, fillet two long edges with 6mm, then place a cylinder (second body), pad the lower surface of the cylinder with 6mm, combine the two bodies and fillet again.

Have you tried this? I get fail at the fillet of the cylinder. using v1.1-dev-39416

[@DuyQuangDang]

Yes we can try that! It's a lot quicker! But again, we have to work with surface if we want to fix some sharp line transitions, also topology :)

Thanks!

[@DuyQuangDang]

Thanks alot!! :)

[@w.binder-freecadchannel]

If I have to fillet a larger object in several places, it takes a lot of time, is there a simpler method? Thanks 😊

Can someone explain the G1, G2, G3 continuity?

[@Pixelwaster]

the continuity between surfaces - how smoothly they connect to one another. G0 - position (touching) G1 - tangent (angle) G2 - curvature (radius) G3 - acceleration (rate of change of curvature) From "Freeform surface modelling" by Metzger and Eismann (sorry no linking to pdf)
