STL quality can be improved by this key
By activating the key, a higher quality can be enforced when generating STL files
1: If set to 1, a new faceted model will always be created whenever a STL file must be written (e.g. geometric search, 3D-preview).
0 (default): If left at its default value, 0, a new faceted model for the STL file will only be created when either no faceted models exists in the part file, or the file is modified. Otherwise, the existing faceted model will be used (faster).
High STL quality improves the geometric search.
Possibly existing facet models have lower quality or existing multi-body models are not supported by the interface.
