How can I get the angle of the text created by model.Text()?

export function getTextModel(font, caption, font_size) {
  const model = new makerjs.models.Text(font, caption, font_size);

  model.layer = DrawLayerNames.Caption;

  const model_extents = makerjs.measure.modelExtents(model);

  return [model, model_extents];
}

const [caption, caption_extents] = getTextModel(font, `H: ${H}`, render_options.font_size);

  caption.origin = [
  // some origin
  ];

  makerjs.model.rotate(caption, /* some angle*/, caption.origin);

How can I find out how rotated the text is in another part of the program?

The report uses makerjs.models.Text, makerjs.measure.modelExtents, and makerjs.model.rotate; start by tracing those API entry points in the repository. Confirm whether the model exposes its rotation state and document the supported way to retrieve it, with an example matching the issue’s JavaScript usage. Done means the angle can be obtained reliably from another part of the program.
