Welcome.
I wanted to use cgkit visualization work actuator. Do cgkit model can be done and the actuator piston, for example, without the use of  "blender", 3DStudio MAX? For this you will need two cylinders with flat ends, and we have only cgkit cylinder with rounded peaks, the box crutches. How to create a cylinder, which will enter the second cylinder, and this move?
Thanks
Sorry for my English.
