Plug-in for AUTODESK Inventor files

[Roy_043]

Things seem to work fine in V0.19 now. But when I start V0.18 there is an error:
During initialization the error No module named olefile occurred in C:\Users\<username>\AppData\Roaming\FreeCAD\Mod\InventorLoader\InitGui.py
Please look into the log file for further information

I have tried to follow this procedure again (using the V0.18 bin path) and have also tried reloading the addon via the Addon manager. Both without success.

Both without success.

When you have two version of FCs, the other will has this problem. Because you didn't install the wb on it.
The installed information is stored in a public space on c drive for the user. When fc starts, it reads this information. This information direct fc to look for olefile in a fc folder. But the one without the wb doesn't have this file.
This is common problem when you install wb through add on manager. I don't know if add on manager has an option to install all wb information inside fc only. And you could try install wb manually, Copy everything under yourfc/mod/yourwb. In this case, maybe move everything under C:\Users\<username>\AppData\Roaming\FreeCAD\Mod\InventorLoader\ to you fc folder. In this way, your 0.19 still fine with the wb. Your 0.18 doesn't give an error msg and doesn't have the wb.

Both errors should be fixed now.

Both errors should be fixed now.

Thanks.

There are other issues with the Window_test.dxf file though.
In the file there are 7 solids.

Two are 1000x1000x1000 cubes. These are helper solids that BricsCAD uses for parametrics and to subtract holes from walls.
If the 'convert to STEP' option is selected the position of one of the cubes is faulty.

The other 5 solids form the window. In the top view the window outline should match the subtractor cubes: the window should be 1000x1000. But somehow the imported window measures 133.33x133.33. A 1/7.5 factor smaller than it should be.

Another thing that is peculiar: The DXF 3D import function always creates a new file. Even if you use the Std_Import command. That is not consistent with how other importers work.

Regarding the installation issues: wouldn't it make more sense to install the dependencies in the
C:\Users\<username>\AppData\Roaming\FreeCAD\Mod\InventorLoader\
folder?

Looks like on first run it will install missing dependencies now. Nice

There is a downside to this approach. If you start a different FreeCAD version it will try to install the dependencies (without success) every time you start the application.

In my case I first installed the add-on in V0.19. I have tried to start V0.18 as administrator and have also tried running that version from a folder other than 'Program Files'. The only solution that I could find is to copy the dependencies from the FreeCAD V0.19 program folder:

Code: Select all

<FreeCAD program folder>\bin\Lib\site-packages\easy-install.pth
<FreeCAD program folder>\bin\Lib\site-packages\olefile-0.45.1-py3.6.egg
<FreeCAD program folder>\bin\Lib\site-packages\xlrd-1.1.0-py3.6.egg\*.*
<FreeCAD program folder>\bin\Lib\site-packages\xlutils-2.0.0-py3.6.egg\*.*
<FreeCAD program folder>\bin\Lib\site-packages\xlwt-1.3.0-py3.6.egg\*.*

I tried this plugin before, not really want to install it on both version of FCs. Now I just try to avoid using addonmanager. Alway install plugin manually.
