3d design disappears when I do the fillet
Hi! I am new to FreeCAD,
We imported a .stp file into freecad, and converted it to freecad format, while trying to create fillet on the edge,the entire 3D model was disappearing, but sometimes, I am able to perform the operation on one edge alone.
We would like to have all the edges filleted at a very minimum possible radius value.
I wasn't able to find a valuable solution from the tutorial videos, also I saw a similar thread posted in 2015, I also wanted to know if there has been any fix found for this problem, will we be able to resolve this issue, in the existing 3D model itself.

Re: 3d design disappears when I do the fillet
Fillets fail if they consume the complete adjacent face. More may be said if you provide the file.

Hi Chris,
Hope you are doing good.
I have attached the file here, could you have a look at it, and let me know why the fillet doesn't work, when I select the bottom edges of the rectangular pipe and the intersecting surface of pipe and tank. The 3D geometry disappears when filleted.
Re: 3d design disappears when I do the fillet
I only can guess what you meaning.
I think you mean this edges (red arrow). The reason why fillet not working is, that it runs out tangential. Also the object is self have errors. This often comes from a bad step export. But there is a workaround.
First pad the upper surface (important: setting refine set to true).
Fillet the edges.
Cut the plane, what you have added before, away.
Just said, because the error of the geometry before is still there, later some issues can occur. But to be honest, this model is easier to make in FreeCAD completely as imports some corrupt step model.

Re: 3d design disappears when I do the fillet
Thank you, But I am trying to achieve the fillet in the highlighted edges alone, If I pad the upper surface I would miss that edge.
@papyblaise, I don't require the entire pipe to have fillet, but how did you achieve it?

Re: 3d design disappears when I do the fillet
no problem, just a little less
I redo from zero, you will cut afterwards

Re: 3d design disappears when I do the fillet
thank you @papyblaise .
But could you say how did you achieve it?

To analyze a model:
- make everything invisible
- in Part workbench: make only one of the objects on deepest nesting level visible
- investigate its properties
- make it invisible
- continue with other objects on the same level
- continue working up the tree and investigate the properties of booleans and other operations
