OpenSCAD实现圆角矩形，可以参考如下代码：

// 圆角矩形模块代码 module roundedcube(xx, yy, height, radius) { difference() { cube([xx, yy, height]); difference() { translate([-.5, -.5, -.2]) cube([radius + .5, radius + .5, height + .5]); translate([radius, radius, height / 2]) cylinder(height, radius, radius, true); } translate([xx, 0, 0]) rotate(90) difference() { translate([-.5, -.5, -.2]) cube([radius + .5, radius + .5, height + .5]); translate([radius, radius, height / 2]) cylinder(height, radius, radius, true); } translate([xx, yy, 0]) rotate(180) difference() { translate([-.5, -.5, -.2]) cube([radius + .5, radius + .5, height + .5]); translate([radius, radius, height / 2]) cylinder(height, radius, radius, true); } translate([0, yy, 0]) rotate(270) difference() { translate([-.5, -.5, -.2]) cube([radius + .5, radius + .5, height + .5]); translate([radius, radius, height / 2]) cylinder(height, radius, radius, true); } } } |
