I want to avoid converting my objects into meshes. Can I boolean from extruded curve objects? For example, here I am trying to boolean out the interior of the letter "a" from an extruded svg. Thank you!

You can use a Geometry Nodes modifier (on your extruded .svg object) instead of Boolean to accomplish that:

Couple of things to note:

  • There's no such thing as a curve with faces. When you use the Geometry > Extrude or Shape > Fill Mode options of a curve from the Properties panel, the result is actually a mesh. What's happening is equivalent to a setup like Fill Curve > Extrude Mesh in Geometry Nodes, it's just not exposed to neither the user nor to the other modifiers.
  • Take care to keep the Object Info node in Relative mode so your curve/text object's world position is used.
  • Unfortunately, the Mesh Boolean node in Geometry Nodes operates only in the Exact mode of the Boolean modifier (instead of Fast). Good for more precise results, but also much slower.
