Does anyone know a way of quantizing sensor data in MapleSim?

I cant figure out how to add friction to my translating block. This is an example of what I was trying I thought I would take the Translational friction component attach it to the current force line being applied (because the direction of motion can be extracted from it) and then attach the friction force line and the original force line to the block im moving. I have tried hooking this up in series and in parrallel (the picture is with the component in parrallel) Here is a picture because this is hard to follow: http://yfrog.com/eufrictionattemptj
