How to draw a line with background

[crazyfireji]

I want to plot a line on the mesh, but the line will covered by mesh(as the fig following), is there any method to plot a line with background???

translate!(lineplot, 0, 0, 10) should move the line in front of the mesh. You can either do that, plot with Point3f with explicit z value, or plot the line after the mesh (CairoMakie only!).
