Generate a vector in the Z-axis direction

Unit Z is used to generate vectors in the Z-axis direction.

Let’s look at an actual usage example.

Components used：①Brep ②Unit Z ③Move

Let’s try to move an object in the Z-axis direction using a Move.

Enter the numerical value of the distance you want to move into the Unit Z(F) and connect the Move(T).

In this case, the distance value is set to 500.

Then the object moved in the upward direction.

Components used：①Rectangle ②Unit Z ③Extrude

Using Unit Z, try to extrude in the Z-axis direction.

This time, we will create a rectangle with Rectangle and extrude it with Extrude.

the Rectangle will create a rectangle.

The Unit Z(V) is connected to the Extrude(D) and extruded like this.

As you can see, Unit Z can produce vectors in the Z-axis direction.
