Troubleshooting
|
|
===============
|
|
|
|
The BlenderBIM Add-on is alpha software. There are many bugs! When something
|
|
goes wrong, you may see some computer code flash up on your screen. You may
|
|
also see an error message:
|
|
|
|
.. image:: images/error-message.png
|
|
|
|
**Don't panic!** Click on the button that says **Copy Error Message To
|
|
Clipboard**. You will need to paste this text in a bug report.
|
|
|
|
If you do not have a GitHub account, you will need to sign up to report a bug.
|
|
In addition to pasting the error message text, please also describe what you
|
|
were doing, and attach your IFC file or screenshots if relevant.

If your issue is particularly complex, you can also chat live with developers
|
|
or other powerusers.

Installation issues
|
|
-------------------
|
|
|
|
If you are unable to install the BlenderBIM Add-on, make sure you are using
|
|
**Blender 4.1** installed from https://blender.org/ and are installing the
|
|
latest version from https://blenderbim.org.
|
|
|
|
Other common solutions are listed below. If none of these fix the problem, you
|
|
can `report a bug <https://github.com/ifcopenshell/ifcopenshell/issues>`_ or
|
|
`live chat with a developer <https://osarch.org/chat/>`_.
|
|
|
|
1. **Some other error prevents me from installing or doing basic functions with
|
|
the add-on. Is it specific to my environment?**
|
|
|
|
Try installing and using the BlenderBIM Add-on on a "clean environment". A
|
|
clean environment is a fresh Blender installation with no other add-ons
|
|
enabled with factory settings.
|
|
|
|
To quickly test in a clean environment, first :ref:`find your Blender
|
|
configuration folder<users/installation:where is the add-on installed?>`.
|
|
Rename the folder from ``X.XX`` to something else like ``X.XX_backup``, then
|
|
restart Blender and try follow the :doc:`installation
|
|
instructions<installation>` again.
|
|
|
|
If this fixes your issue, consider disabling other add-ons one by one until
|
|
you find a conflict as a next step to isolating the issue.
|
|
|
|
2. **I get an error similar to "ImportError: IfcOpenShell not built for 'linux/64bit/python3.10'"**
|
|
|
|
If you are using a Mac, be sure to use the Mac Silicon version if you have a
|
|
newer Mac. The only exception is if you have installed Blender using Steam
|
|
on a Mac, in which case you need to use the Mac Intel download.
|
|
|
|
For all other scenarios, check the BlenderBIM Add-on zip file which you
|
|
downloaded. The zip will have either ``py39``, ``py310``, or ``py311`` in
|
|
the name. See the instructions in the :ref:`devs/installation:unstable
|
|
installation` section to check that you have installed the correct version.
|
|
|
|
3. **I am on Ubuntu and get an error similar to "ImportError:
|
|
/lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29 not found"**
|
|
|
|
Our latest package which uses IfcOpenShell v0.7.0 is built using Ubuntu 20 LTS.
|
|
If you have an older Ubuntu version, you can either upgrade to 19.10 or above,
|
|
or you'll need to compile IfcOpenShell yourself.
|
|
|
|
4. **I get an error saying "ModuleNotFoundError: No module named 'numpy'"**"
|
|
|
|
If you have installed Blender from another source instead of from
|
|
`Blender.org <https://www.blender.org/download/>`__, such as from your
|
|
distro's package repositories, then you may be missing some modules like
|
|
``numpy``. Try installing it manually like ``apt install python-numpy``.
|
|
|
|
Common issues
|
|
-------------
|
|
|
|
1. **I get an error similar to RuntimeError: Instance #1234 not found**
|
|
|
|
Blender saves and loads projects to a ``.blend`` file. However. the
|
|
BlenderBIM Add-on works with native IFC, and this means instead of saving
|
|
and loading ``.blend`` files, you should instead save and load the ``.ifc``
|
|
project.
|
|
|
|
If you have opened a ``.blend`` file, there is a risk that the contents of
|
|
the ``.blend`` session do not correlate to the contents of the ``.ifc``,
|
|
which can cause this error. Unless you are an advanced user, only save and
|
|
load ``.ifc`` files.
