> meshes; new element qualities available through API; new IGES export; new volume  
> glyph; OCC curve loops can now be oriented based on the sign of the first curve;  
> better mesh node visualization; added suppport for model attributes in MSH2  
> files; new mesh renumbering capabilities in the API; new GAMBIT mesh reader;  
> replaced Geometry.OCCSafeUnbind with more flexible Geometry.OCCFastUnbind (which  
> can be set for boolean operations as well); added support for editing STEP  
> headers; small bug fixes.

thanks, hopefully it’s not having serious problem in PrePoMax to upgrades.

as i know, R-Tree algorithm for hex-dominant mesh being re-enabled at this version, even the result is not so good as previous version in 3.x due to some reasons.

Hi,

just one more thing i’d like to suggest is adding the option “progression” for edges (bias factor).

Thank you

I agree, but I need to add a feature to define the number of elements per edge first.
