Export OBJ

1. Select the Solid or Sheet you want to export.

   • If nothing is selected, all displayed Solids and Sheets will be exported.

2. Click P-Menu > Export/Save as....

3. A save-as dialog box will appear.

   • Enter the file name.
   • Select Wavefront OBJ (*.obj) as the file type.

4. The Export OBJ dialog box will appear. Configure the options.

   Option	Overview	Detail	Recommended Value
   Topology	Shape of the exported polygons	Tris - triangular polygons only. Quads - quadrangular and triangular polygons. Ngons - polygons with multiple sides, including quads and tris.
   Show Wireframe	Display the wireframe of the exported mesh	Useful for previewing topology and density, which gauges the overall surface quality before exporting.
   Density	Overall polygon density	The only value that automatically adjusts other settings. Lower value: fewer polygons, rougher shape. Higher value: more polygons, more detail.
   Min Width	Minimum polygon size	Increase to avoid congestion of small polygons in areas like minute fillets.
   Max Width	Maximum polygon size	Decrease to avoid extremely large polygons or to make polygon size more uniform.
   Edge Plane Tolerance	Maximum allowable deviation of edges (in cm)	Similar to Face Plane Tolerance, but affects edges and face boundaries more than the center of the face.
   Face Plane Tolerance	Maximum allowable deviation (in cm)	Lower value: more polygons, more detail. Higher value: fewer polygons, rougher shape. One of the most effective ways to control polygon count.	Low poly: 0.01 - High poly: 0.0001 If you need a value smaller than 0.001, consider decreasing Max Width instead.
   Edge Angle Tolerance	Maximum allowable angular deviation of edges (in radians)	Similar to Face Angle Tolerance, but affects edges and face boundaries more than the center of the face.	Low poly: 0.35 - High poly: 0.15
   Face Angle Tolerance	Maximum allowable angular deviation (in radians)	Lower value: curved surfaces converted faithfully, more polygons. Higher value: curved surfaces converted roughly, fewer polygons.	Low poly: 0.35 - High poly: 0.15

   Option	Overview	Detail	Recommended Value
   Curve Max Length	Maximum allowable length of a curve segment
   Plane Angle	Maximum allowable ratio between plane tolerance and max width	Useful for obtaining more quadrangles or polygons.
   Remove Small Features	Strip tiny surface details on export	Defines a bounding box threshold — any detail smaller than the specified size is omitted. Ideal for high poly to low poly workflows.
   Inflect	Preserve surface quality	Adds detail in areas where curved surfaces transition from convex to concave.
   Simplify Radial Surfaces	Simplify radius geometry to improve edge flow	Orients spheres, cylinders, tori, and cones along a common axial direction so edge flow lines align more predictably during faceting.
   Convex Ngons Only	Prevent concave ngons for cleaner topology	Available only when exporting Ngons. Forces all exported ngons to be convex, inserting extra faces where necessary. Results in reliable topology and consistent normal shading at the slight cost of a higher ngon count.
   Scale	Export scale multiplier	Applies a multiplier to all exported coordinates for correct unit conversion in the target application.
   Up Axis	Orientation of exported geometry	Sets the up axis to match the conventions of the target application.
