OpenSCAD module now in Master

[jriegel]

Shoogens OpenSCAD module is now merged into master.

I think some testing and some small changes and its ready for the 0.13

Thanks to shoogen for that great module!

This was example006 from the openscad embedded examples. I adjusted the transparency of the cube so the spheres are visible.

Objects that use the minkowski function give a syntax error when opening the csg file. I used this example from the openscad manual

Code: Select all

$fn=50;
minkowski()
{
 cube([10,10,1]);
 cylinder(r=2,h=1);
}

At first a like to add that this importer is Keiths project and that i only tried to pack it into a module.

since the development were sperated from FreeCAD until yesterday, i used github to keep track of found bugs. https://github.com/5263/FreeCAD/issues/
There is a issue for every OpenSCAD example file except for 001-005 and 011-015.
And please do me a favor, if you found a problem in example009 please to a little forum search to find the appropriate topic to describe the problem. Since example009 imposes a lot of different problems.

In example006 the main problem is the 'render' statement (https://github.com/5263/FreeCAD/issues/21). In order to mimic the OpenSCAD behavior it should render a 'mesh'. And there has been a lot of disscussion about how close the module should mimic OpenSCAD.
The minkowski sum imposes serious problems, because it doesn't have a counterpart in OCCT. Similar to glide, hull and subdiv. But its a widespread technique to filet edges using the minkowski statement in OpenSCAD.
EDIT:
minkowski statement should raise a not implemented warning and not a syntax error. A patch is available. https://github.com/5263/FreeCAD/commit/ ... 98a6ead1d4
thank you

Jurgen, there is a tipfeller in wix file:

src\WindowsInstaller\ModOpenSCAD.wxi


line 35:

Code: Select all

            <File Id="OpenSCADCommandspy" Name="OpenSCADCommandspy" DiskId="1" />

should be

Code: Select all

            <File Id="OpenSCADCommandspy" Name="OpenSCADCommands.py" DiskId="1" />

Regards,
Petar

Fixed now.

OK, I have made win unstable with this - currently 7z file is up, and msi file is being uploaded.

Will see if the OpenSCAD module is running in the installation..

Ok, cerdits go to Keith.

Sometimes I get confused by all the people already contributing to FreeCAD!

While most of the tools in the Menu are useful only for advanced users. There is a hidden feature that is worth knowing when testing the module.
If you go tho the preferences and enter the path to your OpenSCAD binary and restart FreeCAD you will see a command "Add OpenSCAD Element". This allows to enter OpenSCAD code directly to a multiline editbox in the task panel.
Which the checkobox 'as mesh' enabled you will add the OpenSCAD mesh output (as reference). This allows to visualy judge the result of the importer.
Additionaly if the path to the OpenSCAD binary is entered (when restarting FreeCAD) the .scad file extension will be registerd to the module.
