Computer Aided Drawing (CAD)
CAD guidelines for laser parts
Best cutting accuracy is achieved with CAD files, when supplying CAD files please follow these guidelines for best results.
Preferred file format: DXF for cut only and STEP for pressed parts
The file contains only the outline, no frames, no dimension lines, no title blocks and no labels.
CAD file does not contain blind holes, chamfers, or threads.
The lines are solid.
Outer contours are white and closed.
The etching layer is marked yellow, the white layer is cut.
In addition to the CAD file, a PDF drawing is best supplied, If only simple laser-cut parts are requested, a PDF drawing is not necessary, although information for overall dimensions is a must.
PDF drawings are required for bent components that include all necessary bend details and additional specifications such as good side (PVC), grain direction, checker side, threaded/countersunk hole information and finishes.
The CAD file is used as a cutting file. In the event of discrepancies between the CAD and PDF files, the CAD file will be taken as a precedent.
Please ensure that all units are in millimetres (mm) and that there are no overlapping lines or duplicate entities in the CAD file.

Part Identification and Line Marking
Yes, part identification and line marking are important considerations for manufacturers looking to improve their efficiency and reduce costs. By implementing effective part identification and labelling systems, manufacturers can streamline their production processes, reduce errors, and improve quality control.
Line marking is an important consideration, as it helps to ensure that parts are properly aligned and positioned throughout the pressing and post-drill/tap production process.
