For some applications, this orientation is the default. Swap YZ Coordinates (Y Is Up): This option does just what it says: swaps the Y (green) axis and the Z (blue) axis so that the Y axis points up.Export Texture Maps: Select this checkbox to export textures applied to faces with your OBJ file.Usually, this checkbox is deselected because most applications ignore edges when importing OBJ files. If you leave this checkbox deselected, edges are ignored. Export Edges: When you select this checkbox, SketchUp line entities are exported as OBJ line entities.Both faces will render, and materials applied to the front and back faces are preserved. Although this doubles the number of polygons in the exported file, the model will look more like it appears in SketchUp. Export Two-Sided Faces: When you select this option, faces are exported twice: once for the front and once for the back.Triangulate All Faces: Select this option to break the output into triangles instead of multisided faces.When this option is deselected, the whole model is exported. Export Only Current Selection: If you make a selection in your model before you begin the export process, selecting this box exports only the selected geometry.When you export an OBJ file from SketchUp Pro, you can choose from the following options: Click Export and your OBJ file is saved in the location you selected.Select your desired options, which are explained in the following list, and click OK to return to the export dialog box. (Optional) Rename your file in the Save As text box.In the Format drop-down list, select OBJ File (*.obj).Navigate to the location where you want to save your OBJ file.SketchUp doesn’t support the output of NURBS or any advanced OBJ entities. This is different from the tree hierarchy you see in SketchUp’s Outliner, which indicates, for example, that a cushion is a subcomponent of a sofa or that a leg component is nested inside a chair component. In a flat set membership hierarchy, the format identifies what objects belong to a set but can’t tell whether one set belongs to another set. OBJ supports a flat set membership hierarchy, not a tree hierarchy.If the application in which you want to use the OBJ file expects triangulated faces, you can select the Triangulate All Faces option when you export the file to avoid triangulation errors, such as missing or reversed polygons. Each SketchUp face exports as one polygon (unless you tell SketchUp otherwise).When you export an OBJ file, SketchUp replaces any space with an underscore (_). OBJ files don’t support spaces in their file names. Here’s an overview of what you can expect from your exported OBJ files: Understanding what OBJ does and doesn’t supportīefore you export a SketchUp model to the OBJ file format, it’s helpful to know what the format does and doesn’t support. Understanding what OBJ does and doesn’t support.
