Rounding node coordinates in nodeSnap

[Mark]

I'm using nodeSnap, and when defining the nodes, I rounded all the values e.g. instead of 0.01 I just put 0.

After adding the beams, they got messed up again though, which is.. annoying to say the least.

Is there any way of automatically rounding them, so I don't have to do it manually every time?

Thanks
