Can't activate collada on Mac OS

[Hevii Guy]

Hello All,

I've recently come over from the Dark Side . As such, all of my models are in Sketchup format. After I had converted one to .dae format, installed pycolllada as per https://www.freecadweb.org/wiki/Extra_p ... s#Mac_OS_2 and tried to import the same .dae file, I couldn't! The error showed as: pycollada not found, collada support is disabled.

This is a bit confusing since, along with a few others, the following directories had been created:

• /Applications/FreeCAD.app/Contents/lib/python2.7/site-packages/collada/

• /Applications/FreeCAD.app/Contents/lib/python2.7/site-packages/pycollada-0.6-py3.6.egg-info

Whereas the discrepancy in python version is disconcerting, I'm neither sure if it's an issue or, how to "fix" it.

Has anybody encountered similar problems? More importantly, could somebody please provide some guidance so that this can be resolved? Many thanks in advance!

You need to install into the py3 site-packages, I don't know if its 3.6 or 3.7 on osx. collada is pure python so you could move the files to the correct site-packages directory.

You need to install into the py3 site-packages,

Thanks for the input. Seems, therefore, that the Mac OS-specific instructions are no longer valid. I'm going to push my luck now in asking my hand to be held in completing your recommendation Would I need to do some sort of sym linking or, will FreeCAD "know" where to look?

I'm not an OSX user so beware.
I think

Code: Select all

$ pip install --target="/Applications/FreeCAD.app/Contents/lib/python3.6/site-packages" pycollada

I'm not sure about 3.6 or 3.7, you can check your "About FreeCAD" to determine which it should be.

FreeCAD is looking in the ....python3.x/site-packages directory.

Maybe chrisb can offer more insight. After we figure this out we should update the wiki for py3.

After surprising myself that I was able to find the correct directory, I discovered that collada had been installed not only at:

/Applications/FreeCAD.app/Contents/lib/python2.7/site-packages/collada

but also at:

/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/collada

Yet, it s not recognised by FreeCAD as being installed. Hmmm... this has me perplexed.

FreeCAD uses it's own python, so the first one found is FreeCAD's python only py2 instead of py3.
The second is the system installed python that FreeCAD doesn't use, by default at least.

[Hevii Guy]

Thanks for your additional input!

I just did a:

Code: Select all

pip install --target="/Applications/FreeCAD.app/Contents/lib/python3.6/site-packages" pycollada

This resulted in collada being installed as expected within the application directory at:

/Applications/FreeCAD.app/Contents/lib/python3.6

I was quite excited about this desirable functionality now functioning but, when I restarted FreeCAD and tried the .dae import, the same error was thrown at me

FreeCAD uses it's own python, so the first one found is FreeCAD's python only py2 instead of py3

So, should I then try to find a 2.7 version of collada? How would I instruct the pip command to load an earlier version (assuming that I can find one)?

The actual pycollada is not version dependent. It's where it's being installed that is the problem. That's why FreeCAD is not finding it. chrisb is a native osx user so hopefully he will see this. He's on the forum now so hold tight for a few minutes.
