@brunopostle to upgrade, it is a requirement to uninstall the old add-on version before installing the new one. I believe the "Remove" button in the Blender Add-ons settings does this without the need to manually wipe the add-ons folder. I should document this process clearer.
Edit: this "cleaner" process was only introduced a few versions ago, if you had an old BlenderBIM Add-on installed once-upon-a-time, that could create the behaviour you experienced, and so yes, the way is to wipe the add-ons dir. Hopefully it shouldn't reoccur in future releases ever since I've cleaned up the add-on packaging process.
@moult, I'm wary of submitting IFC files that don't import as this is likely my own fault.
However, this IFC example imports ok with default settings, but fails with the new Import Native Representations enabled, error is:
AttributeError: entity instance of type 'IfcProductRepresentation' has no attribute 'ShapeOfProduct'
@Moult what causes it becomes fat? 165MB?
Also, I deleted the old addon and closed and opened Blender, then installed the latest version, but even after multiple times closing and opening Blender it gives error when I want enable it
@brunopostle will take a look :) Likely a bug with the new unstable feature.
@ReD_CoDE it's been about that size for a while now, mostly due to OpenCascade being bundled for documentation features. The OpenCascade may also some with some Qt, which is huge. I'm relying on precompiled binaries to distribute it, so in the future with better infrastructure I'll be able to shrink the filesize drastically. There is also an option of providing an install without all of that, which should drop the filesize to be about 30MB I suspect (IfcOpenShell is 20MB), and have users optionally install it if they want to use those particular features, which are quite separate from the rest of the features.
You probably had an old BlenderBIM Add-on install from a long time ago too. Go to your scripts addons dir, and clear it out (but keep Archipack, I see). Newer versions shouldn't have this issue.
@blenderuser1991 that error looks unrelated to installation, it looks specific to your file. Would you mind sharing your IFC file (it looks like you're trying to import) with me (https://send.firefox.com for end-to-end encryption, and [email protected] ) for debugging? Naturally, I will not reshare your file and will only use it for the purposes of debugging.
@brunopostle - I had a look... you are using IfcProductRepresentation, which is abstract in IFC4, and not "allowed" in IFC2X3:
IFC2x Edition 3 NOTE Users should not instantiate the entity IfcProductRepresentation from IFC2x Edition 3 onwards. It will be changed into an ABSTRACT supertype in future releases of IFC.
Just change it to IfcProductDefinitionShape and that might help :)

Thanks, writing valid IFC files is like playing whack-a-mole, but with hydras instead of moles, and with the rules cunningly hidden in such a way that you could play for a thousand years without finding them.
Blender gives you the flexibility to recreate a personalised BlenderBIM environment. Maybe it's not priority, but in the future it would be nice if BlenderBIM had its own workspace in Blender: with a tab at the top of the screen and a pre-setup layout of windows. Maybe the 3D window with a setup of color and lighting, or image as background, suitable for a nice visualisation of architecture models. Something like these arrangements:
This has been discussed before. It is a good idea, and I believe there are a few prerequisites to execute it effectively. Firstly, myself, @kcress and @stephen_l are slowly ensuring that our add-ons are compatible with each other. Then, with the help of @stephen_l - he will help build another add-on, which has the function as a "package", which will allow a user to quickly set-up Blender with a series of related add-ons to give all of the BIM / CAD functionality they expect, from CAD snapping, Archipack, Dimensioning and sheets, BIM, GIS, and parametric behaviour. This one-click setup will allow users to immediately get a very powerful package rather than have to manage and track separately many different add-ons.
One that's there, we are start optimising the UI to create a unified package. There has been discussion about how to do this effectively, looking at Blender app templates.

@Moult new features and updates looks very cool. i am stuck at blender28-bim-200525 for mac and not been able to update beyond that. i get the error message of ModuleNotFoundError: No module named 'ifcopenshell.util'.
saw the post from @brunopostle to wipe off the addon folder. does this mean to delete the blenderbim folder inside the addon folder? deleting the blenderbim folder alone didnt work for me.
@Arv This sounds like an issue of upgrading from a very old version of the add-on.
Old versions of the add-on was not packaged cleanly - this mean that there were some files that “spilled” outside the add-ons dir. These need to be cleaned up prior to upgrade.
Try this - go into your add-ons dir, and look for any of these files (not inside the blenderbim folder):
ifcopenshell/
OCC/
pystache/
svgwrite/
deepdiff/
jsonpickle/
lib/ # Note: this generally only exists on MacOS and Linux
ordered_set.py
pyparsing.py
If you see them, delete them. Then see it that helps. Subsequent upgrades will not have this problem any more.
@iosvarms take a look at what blenderbim (see above release notes) can do for quantity surveying/takeoff. I think FreeCAD tables/schedules can also do some things.

Comments
@brunopostle to upgrade, it is a requirement to uninstall the old add-on version before installing the new one. I believe the "Remove" button in the Blender Add-ons settings does this without the need to manually wipe the add-ons folder. I should document this process clearer.
Edit: this "cleaner" process was only introduced a few versions ago, if you had an old BlenderBIM Add-on installed once-upon-a-time, that could create the behaviour you experienced, and so yes, the way is to wipe the add-ons dir. Hopefully it shouldn't reoccur in future releases ever since I've cleaned up the add-on packaging process.
Good to hear it works :)
@moult, I'm wary of submitting IFC files that don't import as this is likely my own fault.
However, this IFC example imports ok with default settings, but fails with the new Import Native Representations enabled, error is:
AttributeError: entity instance of type 'IfcProductRepresentation' has no attribute 'ShapeOfProduct'@Moult what causes it becomes fat? 165MB?
Also, I deleted the old addon and closed and opened Blender, then installed the latest version, but even after multiple times closing and opening Blender it gives error when I want enable it
@brunopostle will take a look :) Likely a bug with the new unstable feature.
@ReD_CoDE it's been about that size for a while now, mostly due to OpenCascade being bundled for documentation features. The OpenCascade may also some with some Qt, which is huge. I'm relying on precompiled binaries to distribute it, so in the future with better infrastructure I'll be able to shrink the filesize drastically. There is also an option of providing an install without all of that, which should drop the filesize to be about 30MB I suspect (IfcOpenShell is 20MB), and have users optionally install it if they want to use those particular features, which are quite separate from the rest of the features.
You probably had an old BlenderBIM Add-on install from a long time ago too. Go to your scripts addons dir, and clear it out (but keep Archipack, I see). Newer versions shouldn't have this issue.
I have tried re-installing although I keep getting this error. I am using blender 2.82 and windows 10 64-bit.
@blenderuser1991 that error looks unrelated to installation, it looks specific to your file. Would you mind sharing your IFC file (it looks like you're trying to import) with me (https://send.firefox.com for end-to-end encryption, and [email protected] ) for debugging? Naturally, I will not reshare your file and will only use it for the purposes of debugging.
@brunopostle - I had a look... you are using
IfcProductRepresentation, which is abstract in IFC4, and not "allowed" in IFC2X3:Just change it to
IfcProductDefinitionShapeand that might help :)Thanks, writing valid IFC files is like playing whack-a-mole, but with hydras instead of moles, and with the rules cunningly hidden in such a way that you could play for a thousand years without finding them.
Blender gives you the flexibility to recreate a personalised BlenderBIM environment. Maybe it's not priority, but in the future it would be nice if BlenderBIM had its own workspace in Blender: with a tab at the top of the screen and a pre-setup layout of windows. Maybe the 3D window with a setup of color and lighting, or image as background, suitable for a nice visualisation of architecture models. Something like these arrangements:
This has been discussed before. It is a good idea, and I believe there are a few prerequisites to execute it effectively. Firstly, myself, @kcress and @stephen_l are slowly ensuring that our add-ons are compatible with each other. Then, with the help of @stephen_l - he will help build another add-on, which has the function as a "package", which will allow a user to quickly set-up Blender with a series of related add-ons to give all of the BIM / CAD functionality they expect, from CAD snapping, Archipack, Dimensioning and sheets, BIM, GIS, and parametric behaviour. This one-click setup will allow users to immediately get a very powerful package rather than have to manage and track separately many different add-ons.
One that's there, we are start optimising the UI to create a unified package. There has been discussion about how to do this effectively, looking at Blender app templates.
At the moment, we're still at step 1 :)

@Moult this release motivated me again, good job
The Addams Family's Mansion? XD
@Moult new features and updates looks very cool. i am stuck at blender28-bim-200525 for mac and not been able to update beyond that. i get the error message of ModuleNotFoundError: No module named 'ifcopenshell.util'.
saw the post from @brunopostle to wipe off the addon folder. does this mean to delete the blenderbim folder inside the addon folder? deleting the blenderbim folder alone didnt work for me.
@Arv This sounds like an issue of upgrading from a very old version of the add-on.
Old versions of the add-on was not packaged cleanly - this mean that there were some files that “spilled” outside the add-ons dir. These need to be cleaned up prior to upgrade.
Try this - go into your add-ons dir, and look for any of these files (not inside the blenderbim folder):
If you see them, delete them. Then see it that helps. Subsequent upgrades will not have this problem any more.
@iosvarms take a look at what blenderbim (see above release notes) can do for quantity surveying/takeoff. I think FreeCAD tables/schedules can also do some things.

I think measureit-arch 4.5 addon is not compatible with blenderbim.
@swathi you need to use the latest version of MeasureIt-Arch, and ensure that the add-on dir is has an underscore between MeasureIt and the Arch word, not a dash. Ping @kcress .
I use this version of addon and I am getting this message
But when I disable the Measure_it addon it is working

Great work, a new Technical WIP Demo would be appreciated
Nice!!!! Cool with layers!
I'm not happy about this. Does anyone know why do layers exist in ifc? One of the few things I really like about Revit is that they dared to drop layers.
