First we will create one segment of the snowflake using tools we already know:

• Line
• Extrude Thin / New
• Extrude Thin / Add

Then we going to make a full snowflake using “Circular pattern” tool

Let’s start with simple branch: create sketch on Top

1. Use line tool to draw 3 lines like this:

2. Extrude Thin (New)

After you extrude lines the Sketch will be hidden, you need to show it again by right clicking sketching and selecting “Show” (you may just click on eye icon on sketch entry to show/hide it as well)

3. Extrude Thin (add) the main branch

4. Mirror the part for symmetry

Use “Right” plane as mirror plane

5. Circulat pattern

And just like that you get yourself a snowflake

Bonus - ring

Create new sketch and draw a cicrle. Please note to start circle (first click) above the snowflake and connect with it by second click.
