question seems easy, but I can't get it out - the situation: two objects, a plane and a cube. I want to position the cube on a point (vertex) of the plane, but without using the instance node.

Getting the position of a point from the plane is done via the sample index node, but how to position the cube at this position?!

Thanx in advance, H.

EDIT 1: "Set Position" with "Offset" doesn't give the desired result.

EDIT 2: Also with "Transform Geometry" I don't get the right result.

EDIT 3: node tree ungrouped for better understanding.

In principle, you have already done everything right here:

  1. with the node Sample Index you get attributes of another object
  2. with Transform Geometry you can change the position of the cube

However...

The Sample Index node has two modes:

  • If you use fields (multiple values!) at the input Index, the node also provides multiple values at the output Value and is therefore incompatible with other nodes that require a single value
  • However, if you specify a single static value at the input Index (for example, a simple integer value), the node also returns a single value at the output Value and is therefore also compatible with Transform Geometry.

Therefore, the solution in this case should look like this:

(In this example, index 8 is the middle point of the grid)

This answer explains the behavior in more detail:
Why is there a red line when I try to connect one node to another?
