Hi,
It is almost complete, but I just realized we are still missing a change.
And the PR fails compiling on my Manjaro PC.
So we need some more work on this tomorrow.

Take a cylinder face. It is built from a rectangle wire (4 edges and 4 vertexes), wrapped around a cylinder surface. The 2 opposite edges get fused into a single edge (the seam edge). And the 4 vertexes get fused into 2 vertexes. OrderedEdges and OrderedVertexes include the edges and vertexes that w...

I don't know much about placement either, but I reached the same conclusion as yours.

I think the only thing that OCCT does slightly different from others, is separating the knot sequence into 2 lists (of equal length) : - knots is the list of unique knots (= not repeated) - multiplicities (integers) is the list that represent the number of repetition of each knot. So, a knot sequenc...

so face.curveOnSurface(edge) maps the edge on the surface on which face lies More precisely, or maybe because english is not my native language, I would say that face.curveOnSurface(edge) returns the 2D representation of edge on face, if it already exist, otherwise, one has to project edge on face ...

ok, should be in data section. IMHO.

I don't agree : following the camera movements is purely a Gui thing, so it sounds more logical to me in the View section.

I'm using the Flatten Face tool and sometimes it ignores some edges without warning. In the example file flattening 'Face4' with 4 edges results in an open 2 edged shape. I tried to locate and fix by myself in the python script but it seems to originate deeper. Out of reach for me. I suspect Open C...

How to set like before "fixed view following direction" ?

Set TrackCamera to False

Or you can build all the ruled surfaces that join the 2 offset letters, to close the solid.
