Hi, I find there exist convex/concave lens in some scenes. I don't know how to creat them, , can you give me some details? Something like a tutorial.

in algodoo -1.8.5, right click, insert phunlet.

In there there should be a folder called something like, optics (may be in a folder called prefabs or official)

In algodoo beta (1.9.4+) open the scenelets screen, and it should be in a folder called optics. (may be in a folder called prefabs or official).

Thats off the top of my head so it may be slightly different.

Alternatively, you can create an ellipse/lens by stretching a circle. You can create the other type (I forget which is which) by creating two elipses and making them cut into a box using CSG.
