Shape2DView Placement and Arch Section

[rockn]

I think it's a bug but it's difficult to explain.

Run FreeCAD
Create New Document
Create an Arch Object
Create an Arch Section of this object.
Set her placement different to origin placement.(I think it's almost a problem with angle)
Get a Shape2DView of this section.

Now Move the Shape2DView with the Placement Tool.
Apply change.
You would see the visual placement of Arch Section is changed, the reper of the Section seem wrong.

But when you re-open the file, it seem that Arch Section come back to her right position.

Just move the Shape2DView with Placement Tool and say to me if you have the same behaviour.

P.S. Yorik, I was wondering why your Arch icons show up properly in the Treeview when I have not yet started the Arch workbench yet, where as the new PartDesign Gear, does not use the correct icon if you have not yet started the PartDesign workbench?

Hmm unfortunately I can't test... There is a bug somewhere that makes my FreeCAD freeze when I select a SectionPlane Strange! But as soon as I solve that I'll give it a try.

@Jim, for that, the resource file (which contains the icons) must be loaded when the module initializes (at freecad startup), not when the module activates... Probably in the gear script it doesn't happen that way...

Ok I issued a fix.
For me all seems to work fine... I'm moving the Shape2DView and the SectionPlane, changing their placement, etc, and all seems to react normally...

Actually Yorik I have more information for you.

The section plane actually flips orientation when you click either OK or Cancel from within the Edit menu ...Placement tool, regardless of if you have moved the Shape2DView or not....

I discovered that if you select NOTHING start the Placement tool then click OK, you obviously get "No object selected" error, but it still flips the Section Plane's orientation.

Similarly if you start Placement with nothing selected and click "cancel" it also flips the section plane....and outputs the error message "No object selected".

if you adjust the Placement or Angle values for any of the items in the file in TreeView...this bug does NOT show up.

Also if you use the Draft Move tool on the Shape2DView, the bug does also NOT appear.

[jmaustpc]

I see you have just updated something else in the section Plane so .....I'm still compiling.....

The bug has ....... stayed! still there.

If you just open the file, go to edit menu ...placement with nothing selected then click cancel or OK and the section plane flips orientation.

Ah but I see a problem now, I don't know if it is the same as yours: the direction of the section is inverted!
At some moment in time, apparently, OCC shape direction has switched... This is fixed now.

*EDIT* same conclusion Jim!

Actually Yorik, I've just noticed that Arch section is not working for me at all. So I tested again in this older version below from a week or two ago, (and with older OCC 6.5.0) and Arch section doesn't work either.

I just tried in this old version above as well as the most current version

Section planes are not placing anything in the drawing. The Arch section is supposed to put a cross section of the item its passing through into a Drawing, isn't it?

rockn's test file had a Arch section in it when I open it, but it does not have a Drawing page. But I see that if I add a new Section, it creates a Drawing Page,...but it doesn't put anything in that Drawing.

I created a test file with a default Part Box and Cylinder. I put views of the solids in the Drawing to confirm that it works and work out sensible values for position and scale in the Drawing. But I can't get the Section to show up anything.

Also if I toggle the visibility Property of the Drawing View item, in the comboview view tab, it makes no difference to the image in the drawing page, that is, the view of the cylinder stays visible and the sections remain invisible in the Drawing page.
