Just enter the coordinates (one Block is 100 units long) unfortunitly the sliders in Scratch 3.0 only go from 0 to 100 but if you press the XYZ Button You can enter coordiantes! (first X then Y and then Z) Then you can choose a color! And las but not least press the green “+” Button to add your Block! To remove the newest Block just press the red “-” Button! Your Blocks will be saved in the “Würfel-Anz” witch is an array!
