* Curves objects now support the geometry nodes modifier. * It's possible to use the curves object with the Object Info node. * The spreadsheet shows the curve data. The main thing holding this back currently is that the drawing code for the curves object is very incomplete. E.g. it resamples the curves always in the end, which is not expected for curves in general. Differential Revision: https://developer.blender.org/D14277
