### Transform

 Cube:`max( max( \$Y^2-1, \$X^2-1 ), \$Z^2-1 )` Translate:`max( max( \$Y^2-1, (\$X-2)^2-1 ), \$Z^2-1 )`You can simply translate object by subtracting value to axis:(\$X-2) move 2 to \$X axis.You can also create dedicated expression to help you to play with:`float tx(float val){ ``    return \$X-val;``}`Then replace `(\$X-2)` by `tx(2)` Scale:`max( max( \$Y^2-1, (\$X/2)^2-1 ), \$Z^2-1 )`You can resize any object by divide or multiply the axis:(\$X/2) scale the X axis by 2.(\$X*2) divide the X axis by 2.You can also create a cpecial expression for scaling:`float sx(float val){``    return \$X / val;``}`Then replace `\$X/2` by `sx(2)` Shear:Shear in XY axis:`max( max( \$Y^2-1, (\$X+ \$Y*tan(25))^2-1 ), \$Z^2-1 )`Replace the \$X axis by \$X + \$Y*tan(Angle) `float shearXY(float val){``    return \$X + \$Y*tan(val);``}` Flip:`max( max( -\$X^2-1, (\$Y+ -\$X*tan(20))^2-1 ), \$Z^2-1 )`Flip X-Y : replace \$X by \$Y and \$Y by -\$XFlip Y-Z : replace \$Y by \$Z and \$Z by -\$YFlip X-Z : replace \$X by -\$Z and \$Z by \$X Rotate:`max( max( (\$Z*sin(25) + \$Y*cos(25))^2-1, \$X^2-1 ), (\$Z*cos(25) - \$Y*sin(25))^2-1 )`Rotate X:replace `\$Y` with `\$Z*sin(Angle) + \$Y*cos(Angle)`replace `\$Z` with `\$Z*cos(Angle) - \$Y*sin(Angle)`Rotate Y:replace `\$X` with `\$X*cos(Angle) - \$Z*sin(Angle)`replace `\$Z` with `\$X*sin(Angle) + \$Z*cos(Angle)`Rotate Z:replace `\$X` with `\$X*cos(Angle) + \$Y*sin(Angle)`replace `\$Y` with `-\$X*sin(Angle) + \$Y*cos(Angle)` Twist:`max( max( \$Y^2-1, (\$Z*sind(\$Y*2*\$PI*ch("N")) + \$X*cosd(\$Y*2*\$PI*ch("N")))^2-1 ), (\$Z*cosd(\$Y*2*\$PI*ch("N")) - \$X*sind(\$Y*2*\$PI*ch("N")))^2-1 )`Parameter "N" is N turn/unit.Twist in X:replace `\$Y` with `\$Z*sin(\$X*2*\$PI*ch("N")) + \$Y*cos(\$X*2*\$PI*ch("N"))`replace `\$Z` with `\$Z*cos(\$X*2*\$PI*ch("N")) - \$Y*sin(\$X*2*\$PI*ch("N"))`Twist in Y:replace `\$X` with `\$Z*sin(\$Y*2*\$PI*ch("N")) + \$X*cos(\$Y*2*\$PI*ch("N"))`replace `\$Z` with `\$Z*cos(\$Y*2*\$PI*ch("N")) - \$X*sin(\$Y*2*\$PI*ch("N"))`Twist in Z:replace `\$Y` with `\$X*sin(\$Z*2*\$PI*ch("N")) + \$Y*cos(\$Z*2*\$PI*ch("N"))`replace `\$X` with `\$X*cos(\$Z*2*\$PI*ch("N")) - \$Y*sin(\$Z*2*\$PI*ch("N"))` Thickening:`abs(\$Y*3 + noise( \$X*2, 0, \$Z*2 ) ) - 0.3`By simply absolute your open object and minus with a distance you add a thickness to it.
