I'm still have a strange behaviour.
OS: Ubuntu 12.04.4 LTS
Version: 0.14.3245 (Git)
Python version: 2.7.3
Qt version: 4.8.1
Coin version: 3.1.3
SoQt version: 1.5.0
OCC version: 6.5.1
Make an Arch Structure, add an Arch Section of Structure. (Delete Drawing page).
Move the Section with Edit menu Placement Tool and you will see the viewable placement is wrong. But the placement properties seem good.(After unselect/reselect Section Object)
Exemple : the origin placement of the Section is 0°,0,0,1,0,0,0
The move is : 270°,0,1,0,10,0,0
The viewable placement look like 0°,0,0,1,0,0,10 <== See how X become Z
The placement properties is : 270°,0,1,0,10,0,0
And if you move the section in this properties you see also that change X make move in Z direction the Arch Section.
Oo I have a lot of difficult to explain this. Sorry for the language.
In any case, I see the placement with Edit menu Placement work perfectly with Shape2DView of a Section. It don't move the Section.
