Hello Members; i just try create a formulate in the OpenScad of a mate sound proofing by some pyramids like this: Excellent Sound Insulation Soundproof wall sticker <https://www.aliexpress.com/item/32955836989.html> *and that my script :* ================================ BEGIN SCRIPT // Variables de Pyramide Area_X=82.1; Area_Y=82.1; H=37; Top_Pyramide=0.01; // changeable variable X=Area_X*2; module Pyramide(){ // Pyramide color("green") linear_extrude(height = H, scale = Top_Pyramide) square([Area_X, Area_Y], center = true); } union(Area_X){ // all position got from [ctr]+[4] Pyramide(); // Front for (i = [Area_X, X]){ translate([0, i, 0]) Pyramide(); } // Front Right for (i = [Area_X, X]){ translate([i, X, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([i, i, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([X, i, 0]) Pyramide(); } // Front Left for (i = [Area_X, X]){ translate([-i, i, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([-i, X, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([-X, i, 0]) Pyramide(); } // Back for (i = [Area_X, X]){ translate([0, -i, 0]) Pyramide(); } // Back Left for (i = [Area_X, X]){ translate([-i, -X, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([-i, -i, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([-X, -i, 0]) Pyramide(); } // Back Right for (i = [Area_X, X]){ translate([i, -i, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([X, -i, 0]) Pyramide(); } for (i = [Area_X, X]){ translate([i, -X, 0]) Pyramide(); } // Left for (i = [Area_X, X]){ translate([-i, 0, 0]) Pyramide(); } // Right for (i = [Area_X, X]){ translate([i, 0, 0]) Pyramide(); } } union(Area_X) ; ================================ END SCRIPT <http://forum.openscad.org/file/t2643/Pyramide_Sound_Proof.jpg> in this variable: X=Area_X*2; by changing 2 by 1 or lower i got good model but when i multiple Area_X by 3 or more i got pyramided far from the main object my be i forget a dimension in union(Area_X) function or my script need some work because i'm beginner of using For in my script thank you for our suggesting -- Sent from: http://forum.openscad.org/

Here’s your program in much shorter code. You can change the number of pyramids in the X and Y dimensions by changing the values of totalX and totalY // Variables de Pyramide Area_X=82.1; Area_Y=82.1; H=37; Top_Pyramide=0.01; // changeable variable X=Area_X*2; totalX = 5; totalY = 5; module Pyramide(){ // Pyramide color("green") linear_extrude(height = H, scale = Top_Pyramide) square([Area_X, Area_Y], center = true); } translate([-Area_X * (totalX - 1) * .5, -Area_Y * (totalY - 1) * .5]) for(x = [0:totalX - 1], y=[0:totalY - 1]) translate([x * Area_X, y * Area_Y]) Pyramide(); > On Sep 23, 2019, at 1:45 PM, Higraphics <hichm19956@gmail.com> wrote: > > Hello Members; > > i just try create a formulate in the OpenScad of a mate sound proofing by > some pyramids like this: > > Excellent Sound Insulation Soundproof wall sticker > <https://www.aliexpress.com/item/32955836989.html> > > *and that my script :* > ================================ BEGIN SCRIPT > // Variables de Pyramide > Area_X=82.1; > Area_Y=82.1; > H=37; > Top_Pyramide=0.01; > > // changeable variable > X=Area_X*2; > > module Pyramide(){ > // Pyramide > color("green") > linear_extrude(height = H, scale = Top_Pyramide) > square([Area_X, Area_Y], center = true); > } > > union(Area_X){ > // all position got from [ctr]+[4] > Pyramide(); > // Front > for (i = [Area_X, X]){ > translate([0, i, 0]) > Pyramide(); > } > // Front Right > for (i = [Area_X, X]){ > translate([i, X, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([i, i, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([X, i, 0]) > Pyramide(); > } > // Front Left > for (i = [Area_X, X]){ > translate([-i, i, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([-i, X, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([-X, i, 0]) > Pyramide(); > } > // Back > for (i = [Area_X, X]){ > translate([0, -i, 0]) > Pyramide(); > } > // Back Left > for (i = [Area_X, X]){ > translate([-i, -X, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([-i, -i, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([-X, -i, 0]) > Pyramide(); > } > // Back Right > for (i = [Area_X, X]){ > translate([i, -i, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([X, -i, 0]) > Pyramide(); > } > for (i = [Area_X, X]){ > translate([i, -X, 0]) > Pyramide(); > } > // Left > for (i = [Area_X, X]){ > translate([-i, 0, 0]) > Pyramide(); > } > // Right > for (i = [Area_X, X]){ > translate([i, 0, 0]) > Pyramide(); > } > } > > union(Area_X) ; > > ================================ END SCRIPT > > <http://forum.openscad.org/file/t2643/Pyramide_Sound_Proof.jpg> > > > in this variable: X=Area_X*2; > by changing 2 by 1 or lower i got good model > but when i multiple Area_X by 3 or more i got pyramided far from the main > object > > my be i forget a dimension in union(Area_X) function or my script need some > work > because i'm beginner of using For in my script > > thank you for our suggesting > > > > > -- > Sent from: http://forum.openscad.org/ > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

Have you considered to use the translate of the pyramids within a pair of nested loops: // Variables de Pyramide Area_X=82.1; Area_Y=82.1; H=37; Top_Pyramide=0.01; x_count = 5; y_count = 3; // changeable variable X=Area_X * 2; module Pyramide(){ // Pyramide color("green") linear_extrude(height = H, scale = Top_Pyramide) square([Area_X, Area_Y], center = true); } Pyramide(); for (i = [0 : Area_X : x_count * Area_X - 1]){ for (s =[0 : Area_Y: y_count * Area_Y -1]){ translate([i, s, 0]) Pyramide(); } } <http://forum.openscad.org/file/t824/pyramid_test.png> -- Sent from: http://forum.openscad.org/

Thank You Very Much boxcarmib, i remove *X* variable i work with *totalX* and *totalY* and that make the code simple as you told me, and also can i make rectangle view of object not only square form, Thank You Very Much discuss, *x_count* , *y_count* is the number of pyramids that i can translate it trough x & y axe i learn new things with this examples. -- Sent from: http://forum.openscad.org/
