All settings of
the mesh reduction (reduction of the geometric part complexity) for the
Geometric Search act on the settings of the configuration file $CADENAS_SETUP/geomsearch.cfg.
Mesh reduction is
always processed, when, in the configuration file geomsearch.cfg, the respective
key has been activated (value =1).
[meshReduction] reductionEnabled=1
Furthermore
stlMaxTriangleCount
(the max. allowed number of triangles) from the section [limits] is
relevant. If a part has more triangles than specified, then the number is
reduced to that value.
[limits] stlMaxTriangleCount=250000
If Mesh reduction is switched off and the number of triangles is higher than the value set under stlMaxTriangleCount, then a respective error message is displayed.

|---|---|
As of V9.03 SP3 the default value for the maximum number of triangles has been changed from 100.000 to 250.000. | |
In which cases a difference results by this change of the default value?
For parts, whose number of triangles is between 100,000 and 250,000, a difference is resulting by the change.
Case 1: Mesh reduction switched off.
At the next geo index update the fingerprints are regenerated.
Case 2: Mesh reduction switched on.
A mesh reduction is not necessary anymore for the part now. That means, that the quality of the fingerprints is higher now, which has a positive effect on the topology search. The change only affects added parts or STL as search part or a complete new generation. Theoretically the following could happen: The same part is imported again and has a little bit different fingerprints than the old one, which may cause the similarity to be only 98 or 99 percent instead of 100 percent. The same applies, if a STL is used as search part.
