Creating a Contour Operation

A contour operation is made up of any number of paths that follow the same mechanical and geometric property trends.

Select the rounded arrow icon button from the plugin tab (see outlined in blue below).



The command line will prompt the user to select the paths that will be under that contour operation, and press Enter when all paths have been selected.

The user will be able to add more paths to the operation once it has been created.

 Select the operation in the left-hand list panel to view the profile settings for the operation.




Contour Path Operations

Add Path

Select this button to add one path to the operation, which the user selects from the list. 

Add Multiple

Select this button to add multiple paths to the operation. Once one or more paths is selected from the scene, press Enter to solidity the selection. 

Once more than one path is present in the list, they will be numbered in the order they are printed. To change the order, drag the paths by holding down the hamburger on the right side of each path bar. 

Delete Path

To delete any path, press the X on the right side of each path bar. 

Delete All

Select this button to delete all the paths in the operation. 

Select All Paths

Press this button to select all the operation paths in the field, which can be used with the following Rhino commands:

  • Hide
  • Show
  • Lock
  • SetPt
  • Group
  • Translate
  • Rotate

Flip Paths

Flip the direction of printing all paths in the operation. To flip the direction of a single path, select that path and command 'flip'. 




Nominal width in mm. 

Actual width is dependent on height from substrate and material viscosity. 


The thickness (in the Z direction) of the area. 

Actual thickness is dependent on distance from nozzle to substrate. 


Unitless value to control extrusion rate. This can be used to account for absorption into the substrate.


Controls the flexibility and hardness of the polyurethane, and is independent from geometric parameters. 

A range from 0 - 1, where 0 is the softest formulation and 1 is the hardest formulation of the material set.


Controls the measure of polyurethane's resistance to gradual deformation by shear stress or tensile stress.

A range from 0 - 1, where 0 is the lowest viscosity and 1 is the highest viscosity. Viscosity is heavily dependent on stiffness, and its range decreases as stiffness increases.
