This error indicates the CSG file does not contain the angle parameter. Need to check CSG file.
If in CSG file then maybe you did not make the right changes to where rotate_extrude_action is called

Here is a version of importCSG.py that works on my system.

OS: Linux Mint 18.3 Sylvia
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.4.
Build type: Release

Would be good to test CSG file. i.e. load scad file into OpenSCAD
and export CSG.

If you look at the rotate_extrude it has angle=90. Is that what you also see,

I was getting totally confused with the different versions so I decided to go back to the start and reinstalled version 0.18.4.
I exported from OpenSCAD to CSG format and imported into FreeCAD with the same result as before (360 deg extrude). It had the rotate_extrude angle=90 in the CSG file.
I also imported the scad format file with slightly different result but still with the 360 deg extrude (not 90).
I copied your importCSG.py file into the MOD/OpenSCAD directory and re-ran the program.
Importing the CSG file gives the correct result, importing the scad file gave the same error as previously ie. no rotate extrude.

The above error only occurs with the scad import not the CSG import.

Thank you for your help in resolving this.

I imported the CSG file into the windows version and it failed as expected but then worked fine with your importCSG.py file.
There's no option to import a scad file directly into this windows version.

Thanks

Hi Sid

There is no direct import of scad files in any versions, what happens when you import a scad file is that the OpenSCAD workbench
calls OpenSCAD under the covers and creates a temporary CSG file that ImportCSG.py imports.

You need to tell the Workbench where your OpenSCAD executable is.

With OpenSCAD as your workbench if you click on FreeCAD Preferences you get.

Then if you click on the OpenSCAD icon ( bottom left )
You get

OpenSCAD Options.png (357.14 KiB) Viewed 566 times

Where you see the place to tell the workbench where the executable is.

If you are not seeing the option to import a SCAD file, then the path is probably not set.

When I said check the CSG file, I should have been more precise and said using the OpenSCAD application, rather than FreeCAD.

Hi Keith,

This now makes sense.
The path to OpenSCAD was set to the original version that I installed which doesn't support rotate extrude. I had to install version 2019.05 which came as an appimage and it ended up being installed in a different directory. So FreeCAD was using the old version of OpenSCAD when trying to import the scad file.
This is why the CSG file imported ok as I had exported it directly from the latest version of OpenSCAD.

Thanks again for your help.
Sid
