Scaling, Contouring & Flattening

3 MINUTES

VIDEO NOTES

Important Commands and Actions:
  • Scale the model using the _Scale command and type the scale factor into the command line.
  • Use the _Contour command to generate a series of contour lines across a surface at a given spacing and direction.
  • Use the _ProjectToCPlane command in the TOP Viewport to flatten linework to the XY Plane.
Alternative commands:
  • Instead of _ProjectToCPlane, you can also use the _Make2D command to flatten the linework to the XY Plane.

Modelling Material Thickness

4 MINUTES

VIDEO NOTES

Important Commands and Actions:
  • Create a new sublayer by right-clicking on an existing layer and selecting 'New Sublayer' in the dropdown list.
  • To select multiple objects in Rhino, hold down the shift key.
  • To change the layer an object is on, select it, right-click on the layer you wish to change it to, and select 'Change Object Layer'.
  • Generate surfaces from closed planar curves using the _PlanarSrf command.
  • Split surfaces with curves using the _Split command.
  • Select all the surfaces in your file using the _SelSrf command.
  • To create polysurfaces (3D objects) from planar surfaces (2D), use the _OffsetSrf command, including typing the offset distance direction in the command line.
  • To select all objects on a particular layer, right-click on the layer and select the 'Select Objects' option in the dropdown list.

Creating Supports with Notched Joints

5 MINUTES

VIDEO NOTES

Important Commands and Actions:
  • Select objects in your file and use the _BoundingBox command to generate an enclosed box around what you have selected.
  • Use the _Explode command to polysurfaces into separate surface objects.
  • Use the _Scale2D command to readjust the dimensions of a surface in a single direction/axis.
  • Split the surfaces using the _Split command and selecting polysurfaces as the splitting objects.
  • Use the _SrfPt command to create a planar surface.
  • Generate a polysurface using the _OffsetSrf command.
  • Create notch trimming objects using the _Box tool in the toolbar.
  • Use the _Copy command for the desired amount of notches you need, and use the _Scale1D to adjust their length to what you need.
  • To create the notched profile in each polysurface, use the _BooleanSplit command, using the boxes created as the splitting objects.
This support base method is not compulsory for students to follow, but simply a recommendation and demonstration of a possible method you can use.

Unrolling and Layout

4 MINUTES

VIDEO NOTES

Important Commands and Actions:
  • Turn on the _Gumball along the options panels and select objects to use it to move and rotate them.
  • Generate 2D profile curves from 3D objects using the _Make2D command in the TOP Viewport.
  • Use the _UnrollSrf command to unroll polysurfaces made up of flat, developable surfaces in the XY Plane.
  • Use the _DupBorder command to generate boundary curves from selected surfaces.
  • Use the _Offset command for edge curves you wish to create folded tabs.
Make2D Settings:
  • Drawing Layout: set to 'Current View'.
  • Options: tick 'Maintain Source Layers'.
  • Visible Lines: set to 'CONTOURS' layer.

Nesting Line work

2 MINUTES

VIDEO NOTES

Important Commands and Actions:
  • When copying objects from one Rhino file to another, select what you wish to copy and use the _CopyToClipboard command, followed by the _Paste command in the _New file.
  • To place objects onto the provided layers in the template file, select the objects, right-click on the layer you wish to place them on and select 'Change Object Layer'.
  • Double-click on the provided text to update the required information for your project.
  • Use the _Scale1D command to adjust the dimensions of the sheet boundaries.
  • Finally, use the _Move command to nest you linework within the sheet boundaries.
