Fillet issue with Odd shapes

Post by Dushyant007 »

Fillet command ONLY works with a smooth surface or constant surfaces and DO NOT work if there is a tangential or a bit complex surface as shown in the below images. Is it a BUG issue or something else? The fillet should also work with tangential-contacted surface. Most of the time Fillet gives an error and the Model is completely disaapear.

you can do it in two operations

That's wonderful technique!

I also meet a challenge. Would you like to give a try?

The intent is commercial style fillet at asymetric joint angle.

Fillet radius is 1mm.

First edge for fillet, the angled wall.
Second edge for fillet, the straight wall.

Please the Freecad file with features, because sometimes it's needed to change the order of features and fillets.

Hi Dushyant007,
please try to create the desired radius directly after Fillet002, then it will run around the geometry without problems. Then continue the sequence with Pad003.

How large should the radius be in millimeter?
Best regards

Thank you so much, Wilfried. Great job.

The workflow of FreeCAD is more hard than I expected, usually it takes just a week or two to learn new parametric software for me. I started with NX, after that SolidWorks, Inventor Fusion, and SolidEdge, within a month I learned their workflows. But this one alone will take a month. :?
