Sorry I am not a big developer but wanted to do this for my project and couldn't find a clear answer for this.
This is what I want to do...
1) Main Marker, which has a Plane as its Child. This Plane is essentially a Factory Floor.
2) Machine Marker, which I Place above the Main Marker. This marker has a Machine as its 3DGame Object.
3) Once I Place this Machine Marker, I should be able to Move the Machine 3D Object from the Machine Marker to the Main Marker(Factory Floor).
4)Once on the Factory Floor, Snap to Grid and Save at the desired position.
5) Repeat Step 3 & 4, if there are multiple number of same machines.
A sense of direction on the approach to this Problem will be greatly appreciated. Functions or Packages that could be useful, to make it easier for the User and also somewhat for me.
