Hi all,
As I understand it, some folks would prefer vector hatches in Layout. I don't now use hatching very often but I have been experimenting with a way to do it. Of course I realise that my version of hatching will exist only in Layout & will not be 'Smart' in any way. I apologise if this has been thought of/discussed before.
Essentially, I create a single hatch in a SU file, insert into a Scrapbook & then simply drag-n-drop into the Layout workspace. For instance, a line of batting (insulation) is drawn at full size in SU. The array length should be made long enough to fill the expected space (in LO), at the expected scale. A cross hatch should, of course, be arrayed in both the X & Y directions and again long enough in two directions to fill the expected space in Layout.
Once in Layout the hatch can be manipulated in any way that an inserted SU file can be because it is just another Viewport. In this way rectangular areas can be filled quite easily & quickly. More complex shapes can be filled by tracing round the shape perimeter and using the trace to produce a Clipping Mask from the hatch. More awkward are shapes with an 'island' or hole but with experimentation it is sometimes possible to produce a trace that is joined throughout, including the hole. Once the clipping mask is applied the trace stroke can be turned off in the Format tab leaving just the hatch. A simple filled shape would work as well.
I attach a Layout file (LO 2015) and a PDF of the same. This will, I hope, go some way to illustrating what I have come up with.
