Select objects on multiple layers

Is there a way to select objects in multiple layers but all the layers have a common phrase? Like to use a wildcard character or something

Think of it this way:

  1. Get all objects (All Objects of Type or Block.Objects)
  2. Get their layers (Object.Layer)
  3. Check the layer names to see if they match your condition (String.Contains)
  4. Filter the original list of objects with List.FilterByBoolMask

In other words, get all the objects and filter out the ones you don’t want.

Yeah I am trying to do just that but my layers are named like this “X STR ABDFGH” “Y STR HKJHKJ” “Z STR HKJHKJH” so I just want to filter by items where the layer contains “STR” but I can’t necessarily list every layer

4

So for the String.Contains node, the string to check might be STR?

Trying to use string.contains but the source list is a list of objects (polylines) and it is expecting a string

Try step 2 above :arrow_up:

OOH. OK looks like the mask is working but now the filter doesnt like the input.
Error is dereferencing a non pointer
