Greetings folks; I have a case where I need to print a vars value in plastic, but it currently is a fixed by src edit value, global in scope because its use many times in other modules. IOW, if the value of sz in this call to ver_txt is undef, make it the global value, if its not undef, use the passed value. And just to prettify the plastic, is there a way to stop str from throwing away the .0 of a var its passed? its messing with center=true making the integer figure do a Russian step dance. This module is where I ned to do that. module ver_txt(s,t,sz) { color("Black")translate([-10,0,0])linear_extrude(height=t)text(ver,font = "Utopia:style=Bold",size=s,halign="center" ); color("Black")translate([22,0,0])linear_extrude(height=t)text(tdia,font="Utopia:style=Bold",size=s,halign="center"); }; //places poor text on mating faces of nuts to indicate tooth version and size of nut I am successfully passing in sz, and if undef it still works right now. Should I if(sz==undef convert sz else convert the global var? Never done this before. Hat in hand, take care & stay well all.
