I want to convert a grease pencil line to a spline, the option should show up under “Tool Shelf – Grease Pencil – Grease Pencil – Tools: Convert to Geometry…” or by hotkey Alt-C according to the manual, but neither works, only the search function gives me that option.
The hotkey does not work when you are not in the correct mode. Convert geometry can be found when you turn on edit strokes mode for your grease pencil drawing. It’s in the GPencil menu then
