I'm using LO pattern fill for hatching cross sections. Whilst this looks fine in LO, when exporting toExample.pdf (2.2 MB) pdf the pattern fill linework becomes broken and wiggly, giving a poor quality appearance (see diagonal hatching on top of walls on section cuts in attached file).
I have all quality settings turned on high in SU and LO. I've also tried all permutations of settings in Bluebeam, my pdf viewer.
The problem occurs when viewing with Bluebeam, Acrobat and Mac Preview and prints are also affected. However, when viewed on an iPad the drawings are perfect! It seems as if the quality is there, but there's a viewing problem with pdf output. This only occurs with the LO pattern fill, all hatches, lines and textures brought in with the SU model reproduce fine on the pdf.
Any solutions would be gratefully received as the drawings don't look professional as they are.
