Export Blender option box

  • The Tolerance option sets the accuracy of the meshes. The default chord height deviation of the mesh is set at 0.01 cm
  • The merge option joins the objects in a layer as a single mesh. It also merges double vertices into a single vertex. This option should be ideally used for fully filleted models. If there are sharp edges in the model, unselect this option. Default is off.
