[Solved] A2+ disappeared

[steveinjava]

Just updated FreeCAD 0.18 to Revision 16131 (Git) (It was already 0.18 but earlier revision no) and the toolbar drop down menu has lost the A2+ workbench option. It was always the last on the list for some reason but now it has disappeared. I tried updating it (and restarting) and also removing it and reinstalling it all without getting it back on the menu. Any ideas? Thanks in advance

You can try to delete your config files and the Mod folder in the same directory or to move them in case you want to restore them.

A2+ has moved at the top of the wb list. Have a look there.

No, the list starts with "Arch" and ends with "Web". I still have the older version (still 0.18) on my laptop (Both windoz 10) and that is still showing A2+ at the bottom. I tried the manual addition to the mod folder and that doesn't help. Tried deleting configs and Mod. Tried removing other workbenches. Any ideas? Thanks

Please have a look at the report view for errors shown there regarding A2plus.
If there are such messages, please post them.

Very sorry, didn't read this sensible suggestion before I uninstalled and reinstalled 0.18.1
Now everything works as before with A2+ working fine 'out of the box'.
It does sound like a bug given it works now? If I get a chance I will retry the new version and post the error report.
Thanks all for responses- FreeCad is great and so are its users and developers!

Well, easier said than done. (for me)

Same happened to me. Several WBs not working anymore.

Report says: "['C:\\Program Files\\FreeCAD 0.18\\bin\\lib\\site-packages\\numpy']. One method of fixing this is to repeatedly uninstall numpy until none is found, ...

OK, how could I uninstall numpy?
I found three numpyfolders inside bin\\lib\\site-packages: i.e. numpy, numpy-1.15.3-py3.6.egg-info and numpy-1.16.4.dist-info
There is no file like "uninstallnumpy"

Please advise.

A2plus depends on a correct numpy installation. So you will need at least one valid python numpy module being installed and which can be found by FreeCAD. Perhaps your system is confused by conflicting numpy installations (installation of other software ?). Uninstalling all numpy's from your system will definitely not help. One is needed.

Please give your FC version and system information and what you did before the WB's vanished.

Found the answer for Wind10

In CMD as admin:
cd\ C:\Program Files\FreeCAD 0.18\bin\Scripts>
(this is dir where pip is installed.)
command: pip uninstall numpy

pip will try to uninstall numpy. If succesfull, it answers: Successfully uninstalled numpy-version
Repeat same action until message: Skipping numpy as it is not installed.

Once done, command: pip install numpy

If succesfull, it answers: Successfully installed numpy-version

Thereafter FreeCAD starts without troubles.

Best regards,

Roland
