WHOA!! Everything is green!! But, now the model looks like it did in Maya. If your model appears slightly different from the model in Maya, as mine does above, select your model and type in Explode. Note: If your model looks like it did in Maya (doesn’t look like this) skip ahead to scaling the object. Zoom Selected to Center your model into the Viewports.

Navigate to your OBJ file and select open. You now have a single object with all the normals facing the correct direction. Select the inverted face and type ‘flip’ into the command line. To fix this first explode the object (type ‘explode’ into the command line) or ungroup (type ‘ungroup’ ) until you are able to select individual faces. All normal faces will be the correct object color.Īn object with an inverted normal will now look like this: Then Select a Bright color other than Yellow (Yellow is Rhino’s selection color – this can cause confusion) and Click ‘OK.’ I like to use green.Ĭhanging Backfaces to green will make all ‘Inverted Normals’ appear green, so you know something is wrong. Open the pulldown menu next to Backface Settings, select ‘Single Color for All Backfaces.’ In the options dialog navigate to Rhino Options –> Appearance –> Advanced Settings –> Shaded First type ‘Options’ into the Command Line. Click Export Selection and save your file. In the dialog box select file type and scroll down to ‘OBJexport.’ The default settings are fine. Go to File –> Export Selection and open the dialog box. Now select the object you want to export. Once you have loaded the OBJ Exporter then click ‘Refresh’ and then ‘Close.’ Only load the Plug-Ins you know you are going to use. Note: Do not check auto-load for all the plug-ins at random. In the plug-in Manager scroll down to OBJExport and check the box that says ‘Loaded.’ Check Auto-Load to have the OBJ Exporter Loaded every time you open Maya.

To do this go to Windows –> Settings/Preferences –> Plug-in Manager. I will explain how to use both.īy default Maya does not load the OBJ exporter.

stl files so we will use either Rhino or 3DS Max. The Z Corp 3D Printers recognize Stereolithography (.stl) files. All surface Normals must be facing the same direction. If you were to fill it with water, none would leak out.Ģ.

The model must be ‘watertight.’ This means that the object to be printed must be a solid surface with a thickness, and it cannot have any holes in it. There are two important things to remember when preparing a 3D Print.ġ.
