Best practice for DXF and DWG files

DXF and DWG files are commonly used by CAD (Computer Aided Drafting) programs such as SolidWorks, Inventor, AutoCAD, Fusion and other CAD software. DWG and DXF files are the preferred file types used by Academy’s quoting software and laser cutters to produce parts.

It is very important to make sure these files are well modelled and accurate as any issues in the DXF or DWG could be detrimental to the end quality of the part.

 

We have a few Do’s and Don’ts below to produce a laser cutter friendly DXF or DWG file:

Do:

  • Make sure all parts contained within a file are in the same scale (ideally 1:1).
  • Delete any geometry that is not going to be cut such as title blocks, templates and notes.
  • Make sure geometry is exported the way it will be cut, i.e. as a flat pattern/in its unfolded state.

 

Don’t:

  • Don’t leave any gaps in line work. Open sketches will not be recognized by our laser cutter. It always pays to take a close look at line as even the smallest gap can cause a file to cut incorrectly.
  • Make sure lines do not extend past corners. Sketches with extended lines may not be recognized by our laser cutter, making sure your corners are neat and tidy can save a lot of time (and headaches!) in pre-production.
  • Ensure there isn’t any overlapping geometry. This is an especially big don’t as our laser cutter might recognize all lines in a file with overlapping lines. This will program the laser to cut multiple times over the same area resulting in a poor cut quality. Overlapping lines can be very hard to find until the damage is done.

 

If files are created using the above guidelines, we can swiftly import your part into our quoting software in a matter of minutes.

However, files that have issues can easily add unnecessary hours to a job which can be charged in addition to the price for cutting.
