 May 7, 2009, 03:38 Alter coordinate system #1 New Member   DM Join Date: Mar 2009 Location: GREECE Posts: 13 Rep Power: 9 Does anyone know how I can command the change of coordinate system in a subroutine?

 May 11, 2009, 03:49 #5 Member   Oliver Lauer Join Date: Mar 2009 Location: Coburg Posts: 57 Rep Power: 9 There are two provided subroutines which could be used. DIMENSION CIN(3),COUT(3) CALL GLOLOC(CIN,COUT,ICOR) CALL LOCGLO(COUT,CIN,ICOR) Example from newxyz.f: ICOR=5 do iv=1,nvert CIN(1)=VCORN(1,IV) CIN(2)=VCORN(2,IV) CIN(3)=VCORN(3,IV) CALL GLOLOC(CIN,COUT,ICOR) any operation on local coordinates possible COUT(2)=COUT(2)+OFFSET CALL LOCGLO(COUT,CIN,ICOR) VCORN(1,IV)=CIN(1) VCORN(2,IV)=CIN(2) VCORN(3,IV)=CIN(3) enddo Attention: all vertex values are in SI coordinates, local coordinate systems could be defined in mm
