It can intersect and do path operations on curves and can trace bitmaps, which I haven't been able to do on qcad. Joining the lines helps somewhat the crazy cut order it makes. This is also why the software complains if the sections that you are engraving aren't continous, it might find a section that is open and engrave for ever.Ĭut is straightforward.
It also means that if you overlap two objects on the same engrave layer then it will not engrave twice but stop engraving. This allows for unengraved things inside engraved sections. The first line it comes to it switches the laser on, when it comes to another line it switches off. In the laser cutter software it does it by taking a vertical line and and then seeing where it intersects with your shapes lines. It is non trivial to decide if a point is inside or outside a shape and should be engraved or not. Some engraving may not work at all unless this is used.Įngrave involves filling in the shapes. Note that for complicated paths, it may also be necessary to use the "Unite curves" feature of the laser cutter software. Object -> Fill and Stroke -> Set fill to None.
