- use optional argument to get unicode from translation in python2
- add a utf8_decode function to get unicode from string, bytes, unicode
The method execute must create the sshapes and vshapes objects. They must
1. exist in the cloned (parent) object (by calling the execute function)
2. and be copied to the clone object.
Then the SVG rendering in ArchSectionPlan can find it.
* Allow mesh-based windows (with non-solid shape) to pass through
* Allow precast elements to be clones
* Structure elements now display a different icon when thry are clones
* Arch clones now get the same placements as their cloned object on create
* Fixed the bad export of clones to IFC
* Recoded the Site/Building/Floor IFC export to be more flexible
* If an arch object is selected when creating a window, the window is always inserted in that object
* No more "create from scratch" mode.
* Now needs to create the sketch first, then press the window button
* Added "Auto-include" checkbox in window creation task, to disable auto-embedding
* Fixed wrong orientation of windows
Arch objects can now be based on a Part Compound and will take
its DiffuseColor property. Arch objects that are clones of
such objects will also copy that property.
* Added utility to make non-parametric Arch component
* Ability for all Arch components to be a clone of another Arch component of same type
* Modified the Draft Clone tool to produce Arch Clones if applicable
* Fixed Arch Roofs so they can be based on a solid shape like other Arch objects
* Ability to change the Root element to be imported in IFC preferences
* Ability to import IFC files also as compounds, Part shapes or non-parametric Arch objects
* Added an "only" parameter to importIFC.open() to import only a certain object ID.
* Ability to read colors (IfcSurfaceStyle) from IFC objects
