I don't believe so, not programmatically in a .scad, you could export to stl and look in the stl. or dxf?? ----- Unless specifically shown otherwise above, my contribution is in the Public Domain; To the extent possible under law, I have waived all copyright and related or neighbouring rights to this work.

If your going to do that, have a look at dxf_dim() etc <https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/General> (down the bottom).

If you need access to the points of a 2d (or 3d) object than write your own routines that create e.g. the points of a circle and write your own plotting routine as well. Somewhat like this: fn=16; // create 2d vector shape: circle function circv(r=1,fn=32)= [for(i=[0:fn-1]) [r*cos(360*i/fn),r*sin(360*i/fn)] ]; // create 2d vector shape: star function starv(r1=1,r2=2,fn=32)= [for(i=[0:(2*fn-1)]) (i%2==0)? [r1*cos(180*i/fn),r1*sin(180*i/fn)]: [r2*cos(180*i/fn),r2*sin(180*i/fn)] ]; // display a 2d vector shape module dispv(v){ indi=[[for(i=[0:len(v)-1])i]]; polygon(points=v,paths=indi); } v0=starv(10,20,fn); dispv(v0); echo("circle",v0); v1=circv(10,fn); translate([40,0,0])dispv(v1); echo("star",v1); 2015-01-28 4:55 GMT+01:00 MichaelAtOz <oz.at.michael@gmail.com>: > If your going to do that, have a look at dxf_dim() etc > <https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/General> (down the > bottom).
