can you zip and upload the offending code?
is in odamfcapp.exe, i think is the creation of a default database with the createdatabase function .... for this part my code is the same ...
thierry
could you explain what do you mean by "is not drawn correctly"?
btw, view changes after zooming/paning/rotating in odamfcapp are not saved to file.
sergey slezkin
thank for your answer,
i upload a pdf file to explain why is not good ....
its only with opengl end opengl cache device, its good with wingdi (but it's impossible to shade), and only when the drawing is a new database ...

to help you ... i hope
i have trace the gsopenglvectorizer.cpp when i open a new drawing (new database) opengl don't go in viewdeptrange .....
and when a object is created (new line new block ...), viewdeptrange is not call and zfar & znear are not updated
with a new database
opengl .......

more help
if i add this after create a block
database()->updateext();
extmin and extmax is good :
oddblayoutptr playout = m_layoutid.safeopenobject();
odgepoint3d extmin = playout->getextmin(), extmax = playout->getextmax();
but modelextents in odgsopenglvectorizeview::viewdeptrange return always !extents.isvalidextents() and the zfar and znear value are never update ....
can you help me?

unfortunately it's defect in 1.12 opengl device. it will be fixed in next release.
as a temporary workaround you can add a function to odgsopenglvectorizeview which will set m_bmodelextentsvalid member to false after adding entities to database. it will force extents updating.

thank you sergey,
i try that, and wait for the next release
best regards
