## Lesson goal: Draw lines in 3D

Previous: Drawing in 3D with cubes | Home | Next: Drawing polylines in 3D

In a previous lesson, you learned how to draw lines in 2D graphics. In this mode, you used line(x1,y1,x2,y2) to draw a line between the points $(x_1,y_1)$ and $(x_2,y_2)$.

In this lesson, we introduce a 3D line drawing function, called line3d, that'll draw a line between two points in 3D space, $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$.

line3d(x1,y1,z1,x2,y2,z2,color,thickness)

You can find a list of color codes here. The 3D drawing area will appear under your code-editor. You might have to scroll down to see it.

#### Now you try. Mess around with the code a bit and see what you can come up with.
