i am trying to make a timing belt pulley and i have got myself caught up with a warning about growing normalized tree elements reference attached file, if i un-comment the difference() on line 65 to cut the teeth out of the cylinder() i get warning WARNING: Normalized tree is growing past 200000 elements. Aborting normalization. WARNING: CSG normalization resulted in an empty tree Normalized tree has 0 elements! and nothing displays if i un-comment the render() on line 153 openscad freezes and all i can do is end task it yet if i leave the difference() commented out on line 65 it draws all the gear teach fine, i just cannot difference them against the cylinder() on line 84 i am running openscad 2021.01 on Ubuntu 22.04 in my programs menu i also have a blue icon for openscad that i think says something like nightly release and clams to be version 2023.06.25, i have also tried opening it with that and i still get the same warning and the same not responding if i try to rended the file any help or suggestions would be appreciated regards Jay Dee

You can change the limit in Preferences. I have it set to 1,000,000.

Also I make pulley teeth by linear extruding a 2D version because it is much faster than subtracting teeth in 3D, see https://github.com/nophead/NopSCADlib/tree/master#Printed_pulleys On Sat, 1 Jul 2023 at 08:01, nop head <nop.head@gmail.com> wrote: > You can change the limit in Preferences.
