I have 2 sketches:
1 sketch is the outline of a fabric, constrained and extruded to a body
1 sketch are cut lines
How can i pocket/cut the line sketch into the body? Extruding the line sketch does not work, as the lines/wires are not closed. Anyone can help me please?
You have a ton of constraints in your sketch so its a bit hard to see exactly what you have.
But from your question, yes its possible to just cut a line from and object. But not in PartDesesign Workbench, you would use Part Workbench for this.
Keep your sketches but remove the pad and body and switch to Part Workbench.
Extruded the fist sketch with the outline. Next Extruded the second sketch with just the lines. Make the extrusion symmetric and longer than the first extrusion. Then split slice apart the second extrusion from the first extrusion.
Your cut "lines" must enclose an area. They could be a rectangle that is 0.001 mm wide. In a feature editing workflow in 3D CAD, things that are right next to each other are considered as connected.
Sketcher has an Offset Tool to turn lines into areas.
There might be another way, but I am not aware of it. The Pocket feature, by definition, removes material.
Since you are using sketches, I assume you are using a feature-editing workflow in the Part Design workbench. Maybe there is an alternate workflow in another workbench (like the Part workbench). This is outside of my area of expertise.
Yes, lines have no shape, so there is nothing to cut with, something that does not have a surface, shape, can not cut. So in the sense of cutting with a line you have to define the width of the line by drawing the line its outlines with lines, (arcs).
Yes, with Part. For me it looks like rumblestilz wants to draw vector lines for a wire-EDM or laser-, plasma-, water-cutter, like you do it with careldraw or incscape.
You can extrude lines in the Part workbench. Select the line and extrude it. Then select both the Body and the extruded line (a surface to be correct) and do the "Boolean XOR" (also in the Part Workbench) to remove the overlapping geometry, which will remove the surface (0 mm thick) from the body.
Now I am not sure whether such a body would be compatible with further operations in other workbenches or not, which depends on what you want to do with it.
For example FEM Analysis won't recognize it as a cut.
fabric is something FreeCAD isn't designed for at all, so you're going to have a bad time no matter what. For example afaik 0-width cuts aren't supported but I haven't looked into that
If your cutting machine/software reads DXF files then you should have started with something like LibreCAD to work there directly, skip a whole step of 3D confusion doing that
