Subject: [OpenSCAD] Re: How does concat() actually work ?
I noticed it returns to an echo or to a new array, however it cannot
reassign arrays.
This works
piecePoints0=[ B0, A0, A1, B1 ]; piecePoints1=concat(piecePoints0,side0);
However, piecePoints0=concat(piecePoints(),side0); fills piecePoints()
only with side0 array.
How can I go around this ? I need to add a dynamic number of points
calculated inside a for loop.
