Joining Polygons to Form a Closed Surface

To join polygons into a closed body wireframe:
  1. In the Wireframing Tools, change the Active feature to a polygon feature.
    The Interpretations for the Active feature will be highlighted in yellow.

  2. Click on a polygon interpretation in the 3D view.
    The selected polygon will be highlighted by a cyan outline.

  3. Click an adjacent polygon to wireframe to the first polygon you selected.
    You now have the beginning of a wireframe body. Both ends are highlighted in cyan, meaning you could continue adding to the wireframe from either side.

  4. Continue selecting polygons in the 3D view to define a larger wireframe body.
