Summary0002359: OpenSCAD import is broken by lack of support for hull() function
DescriptionOpenSCAD has a function called hull(): https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Transformations#hull

A simple example .scad file using this is:
hull() {
   translate([15,10,0]) circle(10);
   circle(10);
 }

This translates the following .csg content:
group() {
    hull() {
        multmatrix([[1, 0, 0, 15], [0, 1, 0, 10], [0, 0, 1, 0], [0, 0, 0, 1]]) {
            circle($fn = 0, $fa = 12, $fs = 2, r = 10);
        }
        circle($fn = 0, $fa = 12, $fs = 2, r = 10);
    }
}

When opening/importing either of these, FreeCAD enters some sort of endless loop of death while trying to process the input.

Confirmed. I open the attached file in OpenSCAD, export to .csg, open in FreeCAD, and get an error:

    raise OpenSCADError('OpenSCAD executeable unavailable')
<class 'OpenSCADUtils.OpenSCADError'>: 'OpenSCAD executeable unavailable'

In spite of the error message I do have the OpenSCAD executable.

Works just fine for me.

Maybe kkremitzki has a permissions problem on his/her openscad executable.

There was a fix for hull and 2d objects at https://forum.freecadweb.org/viewtopic.php?f=27&t=18233&p=142918#p142918

 @kkremitzki can we also make keithsloan52 a developer so we can attribute fixes to him?
