Michael:
For the pen settings, check that the correct pens have been assigned for the Building Materials used in the Profile Manager of the
thickened slab profile
, and that they have not been overridden in the Beam Settings > Floor Plan and Section > Cut Surfaces >
Override Cut Fill Pens.
For the black lines at the end of the gravel fill, in the Profile Manager select the edge where you don't want the line, when the Pet Palette appears select the
Set parameters for profiled edge option (rightmost on top row) and uncheck
Show Cut Line in the Custom Edge dialog box.
Is the grade (earth) a Mesh? Have you SEO (subtracted) the Mesh from the Profile?
