Import your work into the template.


'''Maximum material size:''' 1245mm x 710mm x 12.7mm
Check that your work is at the appropriate scale. For example, if you need to make a model at 1:100 scale, scale down your work by 0.01. If you're having trouble with scale, try a [https://www.ginifab.com/feeds/cm_to_inch/scale_converter.html scale converter].


'''Can cut:''' Strawboard,  Plywood
=== Choose material size ===
Choose an appropriate material size for your work. Use the ''layers'' panel to hide unused layers for other material sizes.


=== Nest objects ===
Move elements to fit within the boundaries of your chosen material size. If you need to use multiple sheets, make a copy of the material boundary to prepare separate sheets. Hide any layers for sheet sizes that you aren't using.


Arrange the parts of your design inside this boundary, close together, and favouring the left side. This saves money and reduces material waste. 


Make sure to keep at least 5mm from the edge of your material, and at least 1mm between shapes. This allows latent heat to disperse from your material, preventing charring and the risk of fires.

=== Assign layers ===
Layers are pre-set in the template. Assign parts of your design into the appropriate layers:


# Select the element or elements to assign; for example, select all the curves you plan to cut, or the hatches you want to raster engrave.
# In the ''layers'' panel, right-click the appropriate layer (e.g. Cut or Raster engrave).
# Click ''change object layer.''

=== Line weights ===
</div>Line weights have been pre-set in the template. If you're not using the template, or you've added extra layers, set the following in the ''layers'' panel:


# Set ''Print width'' to ''hairline''
# Set ''Line type'' to ''continuous''


=== Remove duplicated lines ===
Check for any duplicated lines. To remove duplicate lines in Rhino:


# Select your work and the material boundary.
# Use the ''Make2D'' command, and input the settings shown in the ''2-D Drawing Options'' panel below.
# ''Make2D'' will make its own layer group. You should ''Hide'' or ''Delete'' the original layer group to avoid duplicates.

The Laser Cutter cuts at 1:1 scale.
For example, if you need your models at 1:100,
they should be scaled down by 0.01.

Download the template

Download the Rhino laser cutting template.

This is a zip archive containing a 3dm. On Mac, double-click the zip file to extract it. On Windows, right-click and select Extract all... to extract it.

Job setup

Import your work

Import your work into the template.

Check that your work is at the appropriate scale. For example, if you need to make a model at 1:100 scale, scale down your work by 0.01. If you're having trouble with scale, try a scale converter.

Choose material size

Choose an appropriate material size for your work. Use the layers panel to hide unused layers for other material sizes.

Nest objects

Move elements to fit within the boundaries of your chosen material size. If you need to use multiple sheets, make a copy of the material boundary to prepare separate sheets. Hide any layers for sheet sizes that you aren't using.

Arrange the parts of your design inside this boundary, close together, and favouring the left side. This saves money and reduces material waste.

Make sure to keep at least 5mm from the edge of your material, and at least 1mm between shapes. This allows latent heat to disperse from your material, preventing charring and the risk of fires.

Assign layers

Layers are pre-set in the template. Assign parts of your design into the appropriate layers:

  1. Select the element or elements to assign; for example, select all the curves you plan to cut, or the hatches you want to raster engrave.
  2. In the layers panel, right-click the appropriate layer (e.g. Cut or Raster engrave).
  3. Click change object layer.

Line weights

Line weights have been pre-set in the template. If you're not using the template, or you've added extra layers, set the following in the layers panel:

  1. Set Print width to hairline
  2. Set Line type to continuous

Remove duplicated lines

Check for any duplicated lines. To remove duplicate lines in Rhino:

  1. Select your work and the material boundary.
  2. Use the Make2D command, and input the settings shown in the 2-D Drawing Options panel below.
  3. Make2D will make its own layer group. You should Hide or Delete the original layer group to avoid duplicates.

Explode and join hatches and text

For all text and line-based pattern hatches:

  1. Use the Explode command
  2. Use the Join command

Do not explode solid hatches.

Export to PDF

  1. Click File, then Print, or type in Print into the command line.
  2. Under Destination, select Rhino PDF. Under Size, scroll down to select Custom.
  3. Set Width and Height to match your selected material size, making sure units are set to millimetres.
  4. Select the following: Output Type: Vector Output, Output Color: Display Color.
  5. Under View and Output Scale, select Window and click Set. This will return you to the view of your work.
  6. Select the area to print by selecting the corners of the rectangle that matches your material sheet size.
    If you are using multiple sheets, only select one and repeat the PDF export for each sheet.
  7. Press Enter to go back to the Print window.
  8. In the Print window, set Scale to 1:1. Set Margins to 0.00.
  9. Click Print to finish and save file as PDF.
