Question Snap / Align objects via Hololens (in-game) and Editor

We want to create a Hololens App which should help industrial planers to place certain objects (e.g. pipes, engines etc.). However in order to work satisfactory, we need a script (or something similier) which helps to "snap" two objects together and align them properly.

E.g. if we want to connect two pipes, they have to fit exactly to each other as soon as we move one of the tow pipes very close to other one (see attachment).

In addition, we need a good and easy snap function that ensure that objects are "snapped to the ground surface" as soon as we move them close to the ground (see attachment).

This is a common function in Solidworks (CAD) and we need it here, too.

Thanks for your help,

Christoph.
