I was playing with Sweep and came across this crash: Not sure why I cannot use square() inside the function shape(), but when I tried to roll my own shape, OS crashed. I tried both orientations of the square inside shape(), but both crashed. Jon use <sweep.scad> function f(t) = [ (t / 1.5 + 0.5) * 100 * cos(6 * 360 * t), (t / 1.5 + 0.5) * 100 * sin(6 * 360 * t), 200 * (1 - t) ]; function shape() = [ [0, 0], [0, 1], [1, 1], [1, 0], [0, 0] ]; // square(size = 7); /* [ [-10, -1], [-10, 6], [ -7, 6], [ -7, 1], [ 7, 1], [ 7, 6], [ 10, 6], [ 10, -1]]; */ step = 0.005; path = [for (t=[0:step:1-step]) f(t)]; path_transforms = construct_transform_path(path); sweep(shape(), path_transforms);

Ah. I needed to omit the final [0, 0]. Seems like an error message is in order rather than a crash...

I can reproduce the crash with 2015.03-1 but not with 2015.03-2 (on Linux). ciao, Torsten.

I am using 2015.03 under Win 8.1 (according to the Help, About). Where would I find 2015.03-2 for Windows please?

You are correct: I get a parser error in the 2015.03-2 release Thanks!

If there are any Windows devs out there, it would be cool to do auto update. We should have most infrastructure in place for Mac already: https://github.com/openscad/openscad/issues/1470 -Marius
