In this lesson, you repaired all faulty faces and gaps
using
the Import Diagnostics and fillet features. You can therefore thicken the
model to turn it into a solid model.
Sometimes, healing the model fails to repair all import errors. In that case, you cannot form a solid model from the imported surfaces because they do not completely enclose a volume.
You can build the missing surfaces using surface tools, such as Fill Surface,
Lofted Surface, or Planar Surface, and
the
3D Sketch tool. Then use the Knit Surface tool to knit all the surfaces together and
either select Try to form solid in the
PropertyManager or run the Thicken command.
