I've came across another problem with the Scalectrix mode..
The problem is that pieces not always connect seamlessly..
It's all ok as long as you have straight pieces, but if you have a curved piece, it's hard to connect exacly..

It must be exact becouse if it's a little disconnected you can see a gap in the middle when you play the track, and if two pieces overlap than ode can behave badly.

What nice way can i use to place the pieces? Considering also a possible future editor..
