What I want is the image in green (bottom right).
The way to get there is what I think can be much easyer.

How I tried to do:
1 - Imported a DXF image and use “offset shape” tool on them resulting im the red image (Upper left)
2 - Create a rectangle with “Create Rectangle” tool, using “create array” tool create an array of the rectangle, gave it same width and height of the dxf offset result image and group it (bottom left blue image).
3 - Center both images one on top of the other and used the “boolean intersection” tool (red arrow). The result is the image on the upper right corner.
I thought this was enough.
My question is: What did i do wrong for some of the vertical lines disapear?

To obtain the green image (bottom right) I have to use “draw line” tool, create an array of that line, group them and give the same width of red image. Put both images one of top of othr and centred. Then, one by one, adjust the height to the upper line of the red image.

I can somewhat recreate what you’re getting. I say somewhat because in my case I get no shapes from the lower-left preserved. I assume this is because in your example that the vertical pieces are not all perfectly aligned such that there is no space between shapes.

I can’t think of a single step way of doing what you want. Here’s a multi-step workaround.

1. Using your same setup first duplicate the top-left shape
2. After aligning the top-left shape with the bottom left shape, select every other vertical strip from the bottom left shape and group them. Do the same for the other half set.
3. Select the top-left shape and one set of the grouped vertical strips and complete the Tools->Boolean intersection.
4. Repeat for remaining top-left shape and other grouped set
