Parts

Parts are a set of blocks that you use for building a tower. Here are some of the parts:

Part
A part is a rectangular prism which is the starting block for any player. It's default size is 4x2x1. The default tower frame is made of these parts.

Wedge
A wedge is a smooth staircase which is a slide-like part.

Ball (Removed)
A ball is a sphere. Scaling the ball on one axis scales it on all axes. If you were an older user, then you could use it (by copying the part). However, you could still use the normal part to make a sphere by going to properties.

Cylinder
A cylinder is a round object with a flat top and bottom.

Truss
Truss is a climbable block.

Sign
