Hi

line wall:pit AUT has a fill anomaly similar to the debris blocks anomaly that was fixed with 5.3.9.

The end symbol is not filled at the start of each line segment (used here to denote an entrance at the base of a surface cliff).

Also, the shorter length of the thinner line looks good for a stand alone line, but when two lines are joined, as might commonly be the case, there is often a gap.  Perhaps better if the thin line is closer to the same length as the thick line?

And an idea for consideration.

The above image suggests that the symbol size tweaking to match the line length might need its limits adjusting slightly.  The contrast between biggest and smallest symbols seems a bit much to me –perhaps compensating a smaller maximum size with a longer ‘blank’ length at each end?

And yes, I could resolve the size/gap issues by drawing one continuous line, but they cross multiple scraps in some places…
