I want to edit a STL file.
But after imporint the STL into SketchUp, there are hundreds of holes which looks like in the attached image.
I know that the hole can be fixed by draw lines, but is there any automatically method to fix all these holes?
I have tried to use the Merge Faces feature, but it throws following error:
16491 errors occurred. Please report the error and sample model to the author.
16491 - Face merge resulted in lost geometry!
