Translations:Export to STL or OBJ/7/en

Which Method to choose ?
Method 2 is to be preferred. Among the reasons:
 * When you have more than one Body to convert you can use Tools from Mesh Workbench. For example, you can fuse meshes before exporting.
 * Curved surfaces are represented in STL as a series of straight-line segments, generated via tessellation. This results in slightly under-sized inside dimensions for curved surfaces.  If you are exporting to use in 3D-printing, this may result in an under-sized hole, for example.  In such cases you may need a finer tessellation value.  When exporting from another workbench using  →, the tessellation is controlled by the overall display tessellation set in  →  → Part Design → Shape view.  However, because those parameters control the tessellation used to render shapes on the display, decreasing them will slow down display rendering, often significantly. In addition, exporting immediately after changing the display tessellation preference value will not have the desired effect because display tessellation is not updated immediately. One must force a change in the underlying model to cause the tessellation to be recomputed -- for example, by editing a sketch parameter (Setting it to its original value will suffice).
