Fillet fails in some cases

Post by Konstantin »

Hi, sorry for bothering again, but here's another problem.
When I try to apply fillet in Part or Part design module, here's what I get:

Konstantin,

You should display the report view (View --> Views menu), then go to Edit --> Preferences/General/Output window and check both "Redirect python errors..." and "Redirect python messages to report view". This may give you more information when an error happens.

As for the Fillet feature not propagating to all edges, it's because it works only on tangent edges. It will chain all edges that are tangent to each other, then stop when the next edge is not tangent. In such case you need to select all non-tangent edges.

Another way to get the full perimeter of your Pad to be filleted is to select the top face instead. But it fails, which means your profile itself is problematic.

Looking at your sketch, there are many edges that are not tangent to each other. If you edit the sketch and add tangent constraints to both ends of the horse nozzle, then you will see the Fillet succeed.

In retrospect this topic should probably go in "Help on using FreeCAD" rather than in Open discussion.

Thus I'm moving the topic.
