Build a Minecraft Wizard Tower
Plotz online modeller for Minecraft now models Wizard Towers. By entering just a few values in boxes you can create your own custom wizard tower and then go on to build it in Minecraft using whatever materials you like. Plotz will model the walls, floors and roof. The rest is up to you.
Model your Minecraft Wizard Tower
Start by visiting Plotz modeller and click Take me to Plotz. In Plotz you can now build spheres, observatories and Wizard Towers. In the top left, click Change and select Wizard Tower. You will see the default wizard tower with a top floor diameter of 12 blocks and 3 floors just like below.
Adjusting Tower Diameter
Now you can experiment with changing the Wizard Tower. Change top floor diameter to increase the width of the top floor of the tower and all floors below. Large diameter floors mean a taller roof. Eventually Plotz will stop you altering this value when the tower reaches 64 blocks high. That's ground level to sky in Minecraft.
Adjusting Tower Height and step
Increase the number of floors to make the tower higher. Change this in conjunction with the step every value which controls after how many floors the tower steps out.
Adding a side tower
The checkbox next to side tower height will add a side tower. Side towers are about 2/3 the diameter of the main tower and placed on the middle floor (or as close as). The side tower is initially 1 floor high. Once checked, you can increase the side tower height to what you want.
Building in Minecraft
If you have a printer you can choose to print a schematic. I recommend turning off best fit before printing out a Wizard Tower schematic. Also you can step through the layers on screen as you build and I prefer this method myself. Start by entering a value of 1 in Show up to layer then use the up and down arrows next to that value to change it as you build.
