Adding shapes & objects together question?

[Gemini80]

I am familiar with Boolean Operations but am not able to add and create a new shape based on the white stroke lines - please see attached image. The lines are only stroke lines so not a typical shape/object. My wish is to create a standalone shape that is identical to the space the lines take up. I know there is a manual way to do this, i.s. create shapes and fit them to the line structure - but is there an easier quicker way? When I select all lines and press the Boolean Add Operation nothing happens. Thanks for all tips!

boolean operators work only on closed curves, not on open curves.

So in Designer you can use "Expand Curves" to convert the lines into closed curves, and then boolean add.

In Photo, you can use rectangular shapes instead of lines to achieve the same result.

Never the less, if you want to go ahead with strokes alone you could use "Merge Curves" to get one layer with all curves.
