Use the Auto fix function to automatically fix all the errors in a model.
Many 3D print preparation tools rely on a solid being topologically closed. As part of the closing process in LimitState:FIX, other geometric problems are fixed. For example, duplicate geometry is removed and shells that are inside-out or orientated inconsistently with their neighbours are reversed. Get the best surface profile by choosing from a range of hole closing algorithms – including fan, planar, minimum area and smooth.
Automatic merging of solids
All intersecting or overlapping solids are automatically merged together to create a single, shrink-wrapped object that is ready for printing.
Polygons in a 3D mesh should be ordered in an anticlockwise sense as viewed from the outside of the solid. LimitState:FIX will systematically identify and fix polygons in a mesh that are incorrectly oriented.
LimitState:FIX checks if a objects are self-intersecting and fixes them if they are, while ensuring that the final geometry is as close as possible to the original.
Remove noise shells
Solids can contain small shells as well as the intended geometry. These are errors, and sometimes they are an artefact of the software used to create the solid. LimitState:FIX identifies these shells and removes them from the model.
Many tools that deal with STL files require a manifold mesh in order for their algorithms to work correctly. LimitState:FIX will query whether a mesh is manifold and, if it isn’t, mend it.
Often models contain many more polygons than they need to. This can make the file harder to manipulate than it needs to be and can stop it printing properly. LimitState:FIX cuts the number of polygons in a solid, while making sure it still looks right and has accurate geometry.
