With expression-based properties, it is possible to extract and combine parameters (including other properties) to form a string.
For example, I have properties related to timber framing like studs, nogs, treatment, grade, etc.
I have an expression-based property that determines if the wall is of timber construction then combines the above, plus other parameters (composite name etc) to form a note (sentence), if it's concrete, then a different note is formed. This is then used/displayed in a key (Interactive Schedule).
This works really well. However, one limitation is that users, in the key / interactive schedule, can overwrite the expression-generated string with manual text. This appears correct in one instance, however, all the underlying parameters still have the original data/parameters.
While I have several Graphic Overrides that look for these properties with custom values, there's still a risk.
My wish is that somehow there is a way to to lock expression-based properties.
Hi there,
I don't know – maybe all the things I'll write here are already mentioned in this forum... actually if not, I wonder why...
Anyway... I thought I bring this collection of issues about the graphic overwritings... hoping the tool will be reworked soon and get all (and maybe more) improvements in.
- Differentiation of cut and uncut lines
It is the absolute basis of every drawing (and in Archicad available for every tool) to distinguish between this kind of lines. Why "destroys" the GO this option?
In case of renovation, we need red cut fills with black contour lines and red lines for the uncut parts.... but we can't have this currently and can't use the GO for this case. - Control of Building Material (Skins) and not just complete elements
Without adopting the basic settings of Materials, e.g. it is not possible to display composites for drafting properly. E.g. The difference between in solid material and insulation has always to be visible. To get that with overwriting, hatches to (black or gray) solid fills we've set the background fill to this color... but later on in construction planning black background is wrong.
(An other method is, to use different pen sets to achieve correct displays... but It's another workaround to organize this all... it could be easier and more universally...) - Control of GDL-Elements via GO
We mostly have stairs... and because these are GDLs we are not able to overwrite them (just can use the workaround from the point above...) - Hiding elements (edges) completely also in ground plans
Why could this function that came with Version 25-2 not have for elements in ground plans?
(There is still no "invisible" line in the lines menu...)
We could do so much more with this.
That leads me to the next point: - Hiding surfaces without transparency setting in elevations and sections
Transparency for glass etc. and hiding opaque surfaces are two completely different things. Why can we have it only together?
We've to make glass opaque globally to get the option to hide, e.g. demolished building part surfaces.
Why only this way? -
Hiding Skin Separators causes missing Contour Lines
The last point here is really my biggest one.THE PROBLEM
In the GO we’ve this checkbox. It’s a useful function to fade out these lines… we can use the same composite throughout…
But the big bug is, that not just skin separators get hidden, but also contour outlines. So contours are missing and elements like floor structure and furniture, floor and slab, building and soil merge together.
(Yes, in some situation there can be applied a workaround here, called ‘the thicker line wins’, to cope with this bug… but it is still a bug…)
ARGUMENTS
And yes, of course you will argue now, just the expression ‘skin separator’ doesn’t fit really. Because the checkbox has to be activated if lines between different materials are overwritten with the same rule, shall be hidden. (And this function is one of the most important I’d say…)
But even if we can choose only to see separators of skins and different building materials or none of them, it is not acceptable that lines between different (overwritten) materials and different elements are (mostly) not displayed.
Before GO came theres was this simple rule... that separators between elements with the same (overwritten) fills got eliminated… all other one remained. This worked fine. Why could we habe this not again?
CONCLUSION
This "bug" makes the whole GO unusable for drafting display in sections. (In every planning process we have sections. If we can't use GO there… we don't need it for ground plans either.)
To get a clean drawing, I've to add a lot of 2d-lines there.
Almost everything merges together... look at this example...
So if you do nothing else with the GO, fix this first, please.
With the Graphic Overrides you can choose whether the fill overrides affect Drafting, Cover or Cut.
It would be very powerful to have similar control with the lines and line pens.
For example override all cut elements with a red 0.5mm thick pen.
This can be done through the view point settings, but you then can't adjust per view.

When I'm copying elements between files/design options, I want the ability to select "copy to active Design Option."
When I'm copying from project A to project B and those elements are on a Design Option that doesn't exist in project B, project B creates the missing Design Option—and keeps it hidden.
I want the option to create the design option AND show it, create the design option AND keep it hidden, OR paste elements to the active Design Option.
elevations/sections can show surface images, would be amazing to be able to do the same for 3d documents (probably an even more useful uncut appearance than for elevations!)

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.
If element properties import/export with Excel is going to work in the real world, URLs need to function. We need a Hyperlink property data type.
TIL you can open well-formed URLs in the schedule within Archicad. This is... not very useful in collaboration.
URLs in schedules can be opened in PDFs if the text is complete, which it isn’t, unless you want to see these 200-character things on the layout. Truncated URLs pretend to be links, but of course they are broken, which you find out when you get to the browser. Bad UX.
Excel is dumb about recognizing URL strings automatically, but the user can turn the URL into a link. Just don’t change the display text, or the URL will be lost on import to Archicad. Excel readily imports hyperlinks from other software.
When Archicad re-exports the schedule with the URL strings, they get turned back into plain text in excel.
Literally every product is selected on the web; this has to be fixed if the Excel round-trip is to be a real workflow.
PS, they have solved this for BIMx: https://community.graphisoft.com/t5/Visualize-articles/Add-hyperlinks-for-all-3D-elements-in-the-Cus...
every project seems to be a trouble shooting adventure, where these are some of the "best possible results" for wall junctions. short of a complex profile column at every other wall juction, we just have to settle for 'good enough'.
Wishlist item: make it easy and automated to clean up wall junctions in plan!
property lists can get really long in element settings. Making those searchable could be helpful.
Nothing here yet. Try changing your filter criteria!
