Quick Start for Griddle, BlockRanger, and Rhino

Griddle and BlockRanger are mesh generation tools that plug into the Rhino CAD system. Griddle and BlockRanger are only available for the Windows versions of Rhino 5 (64-bit) or Rhino 6 (only available in 64-bit). A single installer (Griddle_xxxx.msi) will install Griddle and BlockRanger products on your computer. The type of license will determine which components are enabled. Rhino, the CAD system (installed separately from Griddle and BlockRanger), is used for constructing model geometry. Instructions are provided below to get started with Rhino, Griddle, and BlockRanger.

Installation (on a non-server machine)
  1. Download the Rhino version purchased, Rhino 5 for Windows (64 bit) or Rhino 6 for Windows from Install Rhino by double-clicking the *.msi file downloaded. IMPORTANT: Do NOT connect the Itasca hardware key to the computer until step 4.)
  2. Download the Griddle installer (only available in a 64-bit Windows version) and double-click Griddle_xxxx.msi to install it.
  3. Reboot the machine.
  4. Connect the Itasca hardware key to the local computer (if a non-network key).
  5. From the Windows Start menu, find the Itasca group Griddle 1.0 and click the “Griddle 1.0 User Files” shortcut. This will open a directory with Rhino plugins to be installed.
  6. Double-click BlockRanger.rhi and follow the instructions to install BlockRanger.
  7. Similarly, double-click, each in turn, Gint.rhi, GSurf.rhi, GVol.rhi, and G_NMExtract.rhi to install Griddle components.
  8. Open Rhino 5 (64-bit) or Rhino 6 and select rvb and rui files from the same directory as above and drag and drop these files into the Rhino viewport.
Installation (network key)
  1. First, the server requires key server driver software to be installed. Download and install the latest Sentinel System Driver Installer here: IMPORTANT: Do NOT connect the network USB key to the server computer before installing this software.
  2. After the server software is installed, connect the Griddle network-version hardware key to the server computer.
  3. Griddle should be installed on a network-accessible workstation (not on the server) as described above (steps 1-8). To set up access to the server network key from the workstation, start Rhino on the workstation and then select the GSurf icon or type _GSurf on the command line. A dialog box will appear that allows you to specify the server location (the machine with the Griddle key).


Griddle and BlockRanger are plug-ins for Rhinoceros CAD software. Rhino, sold separately, is required in order to use Griddle and BlockRanger. Itasca is an authorized OEM reseller of Rhino.

Griddle and BlockRanger require a license key to run with full functionality enabled. A license key can be obtained by submitting a request online. A Griddle license automatically includes full access to BlockRanger. BlockRanger can also be purchased separately from Griddle. A BlockRanger license does not allow access to Griddle functionality. BlockRanger will also work with a FLAC3D v6.0 or a 3DEC v5.2 license key. If a license key is not present, Griddle and BlockRanger will operate in demonstration mode. In demonstration mode, the Griddle surface remesher and volume mesher output a maximum of 600 surface or volume elements, respectively. The Griddle surface mesh intersector does not operate in demonstration mode. BlockRanger will only output VRML format in demonstration mode.

  • Traces of problem areas found by the Griddle volume mesher are outlined graphically and placed in their own layer.
  • Intersecting faces can now easily be located using a new option of the Griddle mesh intersector. Intersections are shown graphically instead of relying on Rhino’s mesh repair report which only indicates the total number of intersections that have been found.
  • Extraction of intersecting meshes is now much easier with Griddle's non-manifold extract plugin.
  • Griddle and BlockRanger now have a file Save As dialog instead of a fixed output file name.
