**Lines not on edges**

Is there some rule or recommendation against lines (type 2) not matching real edges of triangles or quads?

With this, I mean, for instance, lines that pass through some vertices, such as a line between (0,0,0) and (2,0,0), when the polygon's edges are (0,0,0)-(1,0,0) and (1,0,0)-(2,0,0). Or a set of lines that simply draw a figure inside a polygon.

Are these allowed or should I split the polygons or lines so that every line matches an actual polygon edge?
