|Summary||0004746: Section View Shows Hidden Stairs|
|Description||Upon making a simple level containing a floor with a staircase going through it in BIM, a problem is found whereby if the staircase is of structure "One stringer" or "Two stringers", any section view of that staircase will be faulty. (Please see example files).|
By putting the section into a TechDraw ArchView the result is that the entire staircase is shown on top of other geometry regardless of if it is obscured by the floor or even if it is above the horizontal section plane.
For the prior forum discussion see: https://forum.freecadweb.org/viewtopic.php?f=23&t=62227
The suspected affected parts of FreeCAD are: "both Stairs and ArchSection/TechDraw-ArchView has some bug" - paullee
The summary of the discussion: "So, to summarize, "Structure" - "One Stringer" / "Two Stringer" are broken somehow, and no solid is resulted and thus the strange error. Making Riser / Tread Thickness > 0 make Stair return solid, thus also 'fix the problem'." - paullee
The current workaround is to set "Structure" to "Massive" or change "Riser Thickness" from 0 to 1.
|Steps To Reproduce||1. In the BIM workbench create a slab with a hole in it.|
2. Create a wall next to the hole in the floor.
3. Add a staircase through the hole.
4. Set the staircase structure property to "One stringer" or "Two stringers".
5. Move all these components into a level.
6. Section plane the level. This should be horizontally by default. This should also pass through the staircase. If it does not make the staircase longer by increasing Height and Length properties.
7.Swap to the TechDraw workbench.
8. Insert default page.
9. Click on the section in the tree and then click Insert Arch Workbench Object
10. Change the "Scale" of the ArchView if needed (0.02) and change the "Line Width" and "Cut Line Width" if needed (0.2).
