This tutorial shows you how to make a five point star in blender, but the concept can be applied to any number of pointed stars. Included on this page at the bottom is a contribution from Officer Flake on how to make a star in Gepoly.
Multi-Point Star in Blender (By: Decaff_42)[]
Alright, I'm sure that some of you guyts know how to make nice 5 point stars, but until a little while ago it was a mystery to me until I played around in blender and slapped myself in the head for over thinking things.
Here are two examples for how these stars can be used.


Step 1: Insert a Circle. Press the space bar to see the menu below.

Step 2: Make the number of verticies to equal the number of points on the star.

Step 3: Rotate the Pentagon by -27 degrees around the z-axis (Note that this angle will differ when this technique is used with differnt numbers of points). Press n to get the menu.

Step 4: Cut between the verticies of the pentagon with the exact cut tool. Press K and then select:

Hold down crlt to snap the cutter to the nearest vertex and then select the two vertexes for the cut and then select another point somewhere else.

Step 5: Delete the unnecessary edges. These are the original sides of the pentagon that was made from the 5 sided circle. Make sure you are using the edge selection mode and select the edges. Press x to delete them.


Done!

Making Stars in Gepoly (By: Officer Flake)[]
- Make a solid of revolution in 5 steps. This will yeild a pentagonal prism. Cut the prism away till you are left with the polygon.
- Repeat the process but smaller, and start upside down.
- You should have two pentagons, on inside the other.
- Delete both polys, and just play "connect the dots" to make your new 5 point star.
