How wonderful will be to be able to control the attributes the same way we can control the libraries.
A centralize attribute manager that could be refreshed the same way we do the library manager. So all attributes are in sync between all the files of the same project that are interconnected.
Eg. The base building file, the fitout file and the wet area file, that must have the same attributes with matching names and ID's to avoid the nightmare of duplications.
In concept something like this...
and No more publishing and updating of hotlinks required
Same principle could apply to properties and classifications which can also be duplicated if are mismanaged.
Graphic overrides would be much better if we could apply a color range for some properties, parameters or simply data.
One use case is in urbanism where for example I want to show height of the building scheme (either in 3D or 2D site drawing).
As for now, We have to create multiple rules for each possible value.
With color range we could set eg. minimum and maximum value and their representative colours. Or just simply say to assign different colour for a different value for properties with possibility to change he colour if needed.
I am requesting the ability to instantiate IfcSpatialZone when publishing using the MVD IFC4 Reference View from Graphisoft Archicad.
The IfcSpatialZone class appears in the IFC Schema when setting up Property Mapping in the IFC Translator.
However, there doesn't appear to be a way to generate any geometry and map it to that class using the Type Mapping setting.
According to the buildingSMART International (bSI) Technical Report:
| IFC Spatial Zone – Use Cases, Requirements and Implementation | BR-2023-1025-TR | Report |
the IfcSpatialZone entity was introduced in the IFC 4 schema as a flexible spatial object to represent non-hierarchical project decomposition under some functional consideration. The official IfcSpatialZone specification (this URL points out to the current MVD IFC 4.0.2.1. Reference View 1.2. implemented within Archicad) can be found on the buildingSMART website. This entity is a cross-domain/discipline one; therefore, it is also for architecture, structure, facilities, or any other type of infrastructure; therefore, it applies to the Archicad use cases, too.
-
Unlike the traditional IfcSpace entity, which represents physically and logically partitioned space, an IfcSpatialZone may overlap and have independent placement and shape representation.
-
This allows it to express various functional zones such as thermal, construction, lighting, or usable area zones.
-
IfcZone is just an assignment (a collection of IfcSpace objects) but lacks its own geometry, only the addition of Archicad Zones geometry.
The advantage of using IfcSpatialZone is that a geometry can be attached to an independent spatial structure, not following the hierarchy of IfcSite > IfcBuilding > IfcBuildingStorey. There are situations where such spatial structures need to be conveyed, such as safety volumes or urban planning constraints.
The bSI Technical Report also describes five prominent use case clusters for the IfcSpatialZone model-based approach:
-
Spatial Coordination / Reservation
-
Spatial Definition / Declaration
-
Spatial Regulation / Validation
-
Spatial Message / Information
-
Spatial Boundary for Analysis & Computation
So, my wish is to be able to instantiate IfcSpatialZone when publishing using the MVD IFC4 Reference View from Graphisoft Archicad.
"Trace as Reference" drawing when editing Complex profile, so section or another active drawing will be shown in background of Complex profile editor. This way you can easily adjust complex profile to fit to drawing. Drawing must be placed in same position as it was in active plan/section/façade view, so you will have feeling that you editing complex profile in project not in separate editing space.
The Edit Color window is very dated. It needs the ability to input hex color codes and should probably have an eyedropper as well.
If I currently want to colour match something, I have to use the eyedropper in Photoshop and then break down the RGB values to input into Archicad.
I would suggest copying something like the Unreal Engine color picker which works well:
Rhino's Select Color window can also be used for reference:
At a minimum Folders NEED to be hierarchical and should display as every folder structure in AC or CAD program
- For Example:
- A Rhino upgrade only costs $500US around every 14-16 months so it should not be a money issue.
- This is what we got
- Missing options:
- Using Folders to control visibility, priority, lock, properties? . Main problem with this is that a layer can only reside within one folder so this has to be implemented in the Layer Combination side.
- Click to rename Layers needs to return
- Select All - Unselect All, Lock - Unlock, Hide - Show buttons need to come back.
I would like to suggest the addition of Classifications on Composite-Layers and Complex-Profiles-Layers.
Problem:
If we imagine a Composite Wall, with 25cm of Concrete and 20cm of Insulation on the outside.
This is how it looks in the floor Plan:
I would like my Concrete Layer to have Concrete-specific Properties that I can set only for the Concrete Layer. I also would like my Insulation Layer to have Insulation-Specific Properties.
What are examples of such Layer-specific Properties? Here are some really common ones from the IFC Data Scheme, not necessarily bound to it though, could be any Properties that someone would want only on the corresponding Layers.
- Concrete specific Properties (Pset_ConcreteElementGeneral):
- StrengthClass
- ExposureClass
- ReinforcementVolumeRatio
- CastingMethod
- etc...
- Insulation specific Properties (Pset_InsulationGeneral:
- AcousticRating
- FireRating
- etc...
I do not want Concrete Properties on my Insulation Layer. Same vice-versa, I don´t want Insulation Properties on my Concrete Layer. As a matter of fact I can not allow it. For any use case within a BIM project it is just not right to have properties in places where they are not meant to be. For quantity takeoffs within external software it is an absolute nightmare. Also it absolutely stands against buildingSMART Standards just as a semi-relevant side note.
Also the Ifc Entity Mapping is not correct. This example Composite-Wall should have the following IfcEntities according to their Composite-Layers:
- Concrete:
- IfcWall (PredefinedType: NOTDEFINED)
- IfcWall (PredefinedType: NOTDEFINED)
- Insulation
- IfcCovering (PredefinedType: INSULATION)
Solution:
Have each Composite-Layer listed within the Classification and Properties tab, and allow for custom classifications for each of those Layers. This is a quick UI Design of how that could look like. Please note that there are fundamental properties that are on each Layer (ID, Structural Function, Position, Renovation Status, Show On Renovation Filter) and there are also specific Properties only for that particular Layer (see "Materail properties" tab within the UI Design)
(This also solves another Wish which is currently on the Roadmap: Renovation status for composite walls and complex... - Graphisoft Community. That wish is though only a specific need within my bigger wish. My wish focuses on the core problem, missing classifications on composite layers.)
Feedback and Improvements to this design and functionality are always welcome!
Cheers!
