I've watched some tutorials about grease pencil in blender 2.8 by Jama Jurabaev and other blenderers, and I wanted to do the same thing.
But now I have a problem. When I have done drawing and want to convert the lines to curve, there's no "convert to curve" option although they(Jama) easily find it when they hit f3 and type "convert to..." or something.
Of course I did the same thing, but I couldn't find it. I appreciate it if somebody has any idea.
edit:Thanks for your answer! But I still can't find it in the contextual menu.... What on earth is wrong with my blender? I'm in object mode and selecting the stroke object.
