Removing Lines, Borders and Dimensions From Drawings
When making drawings, only include elements that are meant to be laser-cut from flat sheet metal. Items like text, borders, tables, construction lines and various dimension expressions should be left out of all such drawings. Here’s an example of a drawing with far too many lines, borders, text inserts and other non-supported elements:
And here’s the same image as above, but in the proper format:
Features to Avoid
As we noted above, DXF file format is our preferred style. This format does support things like hatch patterns, text or 3D features, but do not use these – they aren’t meant for laser cutting. Our software will often simply eliminate those more complex elements.
Units to Use
Another thing to note about DFX files is that they don’t specify units naturally. As such, we recommend you create drawings using either millimeters (mm) or inches, as this is what our instant quoting Cypress Metals software assumes the dimensions are listed in. Pay particularly close attention here if you use CAD platforms to create engineered parts.
How to Export
DFX supports both binary and text file options, but we prefer text (or ASCII). Again, this is mainly due to the expectation of our software. There will be times where you won’t be given a choice here, but when you are, choose text over binary.
