WARNING! The roof generation is now quite significantly different. This
WILL change your geometry when you refresh roofs from existing models.
- The roof profile now always represents the top of eave. This better
represents how things are built rather than bottom of eave which was
previous.
- The roof therefore always grows down from the profile. The rafter
edge angle can only be acute. This means that the roof will never grow
larger than the footprint profile that you've drawn. (before, the
footprint was not guaranteed to match).
- The roof thickness is now the actual thickness of the roof, not the
"vertical dimension" of the roof. This means that the roof thickness can
now match intended layer thicknesses instead of you needing to do math
to work it out.
I've rewritten the internals of how roofs were generated to be hopefully
a lot simpler but as a tradeoff it's more restrictive. After the
skeleton is generated, non-uniform angles would be handled through
vertex splitting and moving. This works in simple scenarios but fails in
more complex ones. The new approach only handles non-uniform angles on
triangular faces. These faces are really easy to handle compared to
ngons, but are also more robust. The rafter edge angle is also now
handled using a clipping plane, which is a lot, lot simpler than vertex
sliding math.
Each face is now processed separately and then merged at the end. This
means that if a face has a different angle, it will now correctly
represent the different thickness at that portion of the roof.
In the process consistent roof thickness / rafter angle bugs were fixed.
E.g. two objects are selected - tesselation and profile and tesellation being active object. Using s-e with deselect tesselation object as it doens't have a usage but Bonsai would still try to run bim.enable_editing_extrusion_profile on it leading to the error.
Also fix possible issues for hotkey executed without active object (it seems all operators in hotkey do require active object)
Apparently (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62572) coreutils have changed `mv -n` to throw an error now instead of working silently, therefore our build was failing on Mac when Github Action switched from Ubuntu 22 to 24.
`--update=none` seems to restore the old behaviour.
The for/else block was too greedy, meaning that if nothing was selected,
it would still try to create slabs from walls. I find for/else confusing
so I restructured the section to do more early returns and unindent the
logic.
• Removed bpy.context.preferences.themes[0] from the input and hardcoded it in the function.
• color_path now only requires the attribute path suffix (e.g., "user_interface.wcol_regular.text").
• Updated error handling to default to "dm" instead of "lm".
If you move a wall, and that wall has features (e.g. openings), it's
desirable to also move those openings (because they are invisible). This
is a special exception to `should_transform_children` because the
definition of the feature (opening) is inherently tied to the parent
(wall).
What wasn't considered is that this would typically then also move
subchildren of the features (e.g. fills like doors). I'm surprised
nobody caught this earlier.
I did also consider another approach where if you move a wall, it moves
all unfilled openings, and if you move a door which fills a opening, it
moves the opening too. Intuitively it sounds nice, but it doesn't work
because:
- Openings can have multiple fillings. If you move all fillings, they
all fight to move the openings.
- All logic about children goes one way: a placement may have child
placements relative to it. This breaks the convention (if moving a door
instead moves its opening) which can make brains explode.
- It starts to conflate rules about relative / referenced placements
with spatial decomposition. We assume all IFCs are valid and follows the
convention of relative placement but we cannot guarantee this. This also
leads to brain explosion.
Previously the code looked for additive facets (entity, instance)
anywhere in the query, and then only added the default basket once at
the beginning of the query. This change makes it look for additive
facets in order (that way you could start with a default selection, and
then later use an additive facet) and does it per facet list (so you can
omit the additive facet at the beginning of each list).
