Detection of Colision

[Jarema]

When you use LEGo dIGITAL dESIGNER. You can simple plug-in element into another element hole.  I Like this way how LDD detect place to assemble parts.

1. How MLCAD ;LeoCAD ;Stud.io  research this goal.?
2. Where I find this function to turn on ?

What you are describing is called part snapping and it makes parts automatically connect. MLCAD and LeoCAD don't support it from what I know. In Stud.io you can turn it on and off with a menu bar button labeled Snap.

Collision detection is a mechanism that detects when two or more parts overlap, exist in the same space.

I have no idea how any of them are achieved.

Part snapping works for most of the pieces in LDCad. I think this feature is enabled by default. 

In terms of part collision in LDCad - there's no such feature, so you'd better know your bricks and their possibilities. Most of the time it is possible to zoom in and see if parts actually intersect. Not ideal, but still better than nothing
