Hi, I have 4GB and could only process the first 20000 lines. I changed the caches sizes and render elements in OpenSCAD preferences advanced menu by 4x. Those modifications didn't produce any changes in the result. It aborts always at line 20017. Task manager process appear to consume only about 1/10th of the memory available. <http://forum.openscad.org/file/n15230/Capture1.jpg> jpmendes -- View this message in context: http://forum.openscad.org/Test-compile-big-openSCAD-model-tp15226p15230.html Sent from the OpenSCAD mailing list archive at Nabble.com.

This is hard to diagnose without source. It might be a syntax error that is silently gobbling up the rest of the file? Or a bug in Openscad, in which case I have no clue.
