I have a mesh line and I duplicate it to create 5 more lines. However, I want each line to be rotated 45 degrees. The problem is the red line, I am not able to dynamically add input to the node Transform.

$\begingroup$ Probably duplicate? blender.stackexchange.com/a/297889/2214 $\endgroup$– vkliduSep 2 at 8:05

$\begingroup$ Added image to clarify my issue. The issue is that I am not able to dynamically add input to the Transform Geometry node based on the index of the Duplicate Element. Please advice. $\endgroup$– ph_zeroSep 2 at 8:11

The node Transform does not work with fields, but with single values. This issue is described here:
Why is there a red line when I try to connect one node to another?
In your use case, however, you have fields and would have to use the node Set Position.
This processes your geometry point by point, so you would have to calculate the individual positions of the points.
Since you want to rotate points around a certain center, the node Vector Rotate will help you.
And a solution could look like this:
-
$\begingroup$ Can combine xyz be input to transform geometry and used here instead of set position? $\endgroup$– ph_zeroSep 3 at 1:45

$\begingroup$ nvm, the output of duplicate elements is attribute domain and can only be operated/transformed via set position $\endgroup$– ph_zeroSep 3 at 13:13

$\begingroup$ @ph_zero Absolutely correct: You are dealing with Fields here, so
Transform Geometrydoes not work in this case, and you would have to useSet Positioninstead. $\endgroup$– quellenform ♦Sep 3 at 13:18
