Hi all- im a new user and was hoping to get help on drawing shapes for cutting out slots. I just watched a tutorial on making a colander-great work! Was disappointed when no info on the creation of the shape used for cutting the slots was given. Can someone point me in the direction of a detailed description of how this was done?  
I’m guessing it has to do with symmetry constraints, amd repeating a shape?  
Sorry if this description doesn’t make sense.  
I attached a screenshot of the geo shape used for the slots  
Thank you for the help!!!

I haven’t seen this tutorial however a simple way to make the slots is as follows.  
Extrude a thin blade and use the **Pattern** tool to create a circular group (40 in this example). Then **Subtract** the blades from the cone. Hope this helps.
