Welcome to the forum
Once you open the file in SW, go to Tools>Check
You can enable all and "Check". This will show you the open edges and you can do a surface fill
Enable merge entities and Try to form solid. I am getting solid after this
There may be 7 gaps to fill
Which version of SW you use?
Hope this solves the problem
Thanks, the surface fill worked. I'm using 2013 SP1.
On the lower housing I've tried the same steps but the surface voids are more complex and the fill surface feature is failing to work. Any other ideas? On one of them the fill surface feature manager asks me to select edges for blending. I don't want to create a blend as I want the original geometry to remain.
if the leggs are symetrical split the leggs at acertain spot delete the bad body of the leg and they use move\copy body to rotate a copy of a good leg to the deleted position and the use the combine tool to make it on solid body again.
Mulitple bodies works wonders for imports that have problems that are a mirror or symetrical or a circular pattern.
now this is a suggestion as it does look like the part is a pattern.
