Fillet fails to update

Post by Meslomp »

Freecad version:
OS: Windows 10 Version 2009
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.24291 (Git)
Build type: Release
Branch: releases/FreeCAD-0-19
Hash: 7b5e18a0759de778b74d3a5c17eba9cb815035ac
Python version: 3.8.6+
Qt version: 5.15.2
Coin version: 4.0.1
OCC version: 7.5.0
Locale: Dutch/Netherlands (nl_NL)

After having less than 0 time to play with Freecad for a large amount of time I had a go again a couple of days ago.
I have created a little scoop 4 days ago. During its design I have not gotten errors, and even printed a version.

This evening however I wanted to change the length of the handle, and that is were things started to go weird.
I keep getting an error "failed to create fillet". Even if I now take the original design the first fillet (fillet 1mm) and do a re-calculation it will throw an error.
As said I opened the file I left a couple of days ago and all I did was "recalculate object"without changing a single thing. I have been searching the web and in freecad itself so see if I could find what could cause this, but I do not see what is going wrong. When I select the fillet ( fillet 1mm) then all 3 side show up nice in pink. everything seems to be a single piece, and as said I did not change a thing and did not get an error when I created the fillet nor a couple of other fillets after that.

I hope someone sees what I a doing wrong or what is going wrong

* Open "Fillet 1mm" or 2mm or 5mm
* Close it with OK
* Last fillet fail

I think the problem is with Refine.
I don't know why there is yet a seam line underneath when all fillets are with Refine=true.

You should set Refine=true in the last Pad then correct all fillets (suppress + add).

The seam is properly removed here.

Fillet1mm with Refine=true shows seam in the original file.
This seam disapear after opening Fillet1mm and OK it, but after fillet2mm fails.

That's probably due to the topological naming change.

True, but why is the seam still visible with refine=true in the original file ?

That's a riddle to me.
I opened the file and did nothing but changing Refine=True for Fillet 1mm and making it visible. I upload the file in that state, please have a look and check if a recompute shows the seam again.

Your file shows directly an under face without seam.
The original file with recompute hide the seam in Fillet1mm.

I thought changing Refine status would recompute the construction, hiding the seam (and failing latter fillets).

BTW, opening your file and rotating it shows weird view, like a cut in the view (picture).

That's what it does here if I leave the field

I don't know if it is in the file or just an unlucky coincidence of the camera position. A "Fit All" should fix this.

Sketch002 uses a zero dimension instead of a point-on-line constraint. When I fixed that problem the seam disappeared. Due to precision issues there really is a small step at that point.
