Converting your file to CorelDraw

  1. If your file is already in CorelDraw format, skip this section.
  2. If your file is not in a CorelDraw format, open your drawing (we used Solidworks) and make sure it shows the part and lines you're cutting, and nothing else. Delete any lines and elements you don't want cut, such as through-hole indicators.
  3. Make sure your drawing can fit within your laser cutter.
    • At the MSI, the laser cutter can take material up to 12"x24".
  4. Save the Solidworks drawing as a .dwg file. (File > Save As > Save as type: ".dwg")
  5. Place the file on a thumbdrive and transfer it to the computer you will be printing your part from.

Opening the file

On a computer with CorelDraw...

  1. Double-click on the file. Your computer may not recognize the file type (it will pop up a "Do you want to open this file?" dialog). If it gives you this dialog, click 'Open.'
  2. You may get another dialog that says that your computer doesn't recognize the program to open this file with. Go to 'Select program' and select CorelDraw, then click 'Open.'
  3. You should have a window pop up that says 'Import AutoCAD.' The settings should be as follows when you click 'OK.'
    • 3D Projection: Top
    • Scaling: Automatic
    • Auto-Reduce nodes: Checked
  4. CorelDraw will open and you'll see your part on the screen.

Resizing the part

  1. Select the whole drawing by dragging out a rectangle that contains the entire part (click the mouse above the upper-left corner of the part, drag to the lower-right corner, and release).
  2. Group the part together so the entire drawing can be selected at once. (Arrange > Group)
  3. Resize the part as needed. (Usually you won't need to resize your part.)
  4. Make sure your document is set to the right page size (in the MSI, it must be less than 12"x24". (Layout > Page Setup, then adjust the Width and Height settings)
  5. Drag your drawing so that the entire part is within the page you will be printing.
  6. Save your drawing (File > Save As) in the appropriate location in the CorelDraw (CDR) file format.
    • For the MSI Fab Lab, you'll want to save it in the D: drive, "msi-fablab".

Epilog file format

Epilog lasers have a very simple file format that specifies their activity. See Epilog Laser language.
