How Do I Make a Double Concave Shape?


Hi I am in need of help on how to make a double concave lense using Sketchup. Any links or resources to help me with this is greatly appreciated. Thank you Sketchup Community.


You could draw a cross section of it and then use Follow Me to extrude the shape around a circular path.Double Concave.skp (225.0 KB)
