Infilling stl volume with lines

Hi everyone,

I have a structure that I've meshed using the STL format, which means only the outer surface is meshed. Now, I'm looking to create a line cloud within the volume using these outer surfaces. I'm using a printer that operates by printing lines, which is why I need this. The distance between the lines in the z direction will be referred to as sd (slicing distance), and in the y direction as hd (hatching distance). However, the x coordinates will be defined by the surface of the structure. The lines should start from the bottom and continue upward. I'll draw and attach a picture to help illustrate what I'm looking for.

Thanks a lot for your help!

Here is another similar topic that has been asked previously, but to be honest i am not sure how can i import it to my strucure,

Slicing and generating infill is the job of the slicer. Pathing is described by the gcode or machine file, not the STL.

Hi @DGM,

Thanks a lot for the clarification. With your help, I believe I can search more efficiently on the internet. To make it clearer, I've added a meshed STL volume and the sliced line that I'd like to create.
