Thanks a lot Roger.... Its working perfectly... The MasterCam Version being used is X8. * Does other lower versions CHooks behave differently for the same code? * Is tool_manager deprecated?

Hi everyone, Could anyone please help me with how I could add this center drill tool to the toolmanager??? The problem is tool_manager function accepts only tp_tool as a parameter but how do I add TlToolCenterDrill to it???? tp_tool mcToolData; op_tool_info mcToolInfo; mcToolInfo.type = 1; mcToolInfo.dia = 8; mcToolInfo.tip_angle = 118; mcToolData.arbor_dia = 8; mcToolData.oa_length = 45; mcToolData.flute_length = 8; mcToolData.shldr_length = 8; mcToolData.shoulderDiameter = 1; mcToolData.taperLength = 1; mcToolData.op = mcToolInfo; TlToolCenterDrill centerDrill( mcToolData ); centerDrill.SetDrillDiameter( 2.5 ); centerDrill.SetDrillLength( 3.5 ); centerDrill.SetShoulderAngle( 63 ); centerDrill.SetShoulderLength( 8 ); centerDrill.SetTipAngle( 118 ); centerDrill.SetOverallLength( 45 ); centerDrill.SetOverallDiameter( 8 ); centerDrill.SetToolNumber( mcToolInfo.tlno ); centerDrill.SetName( "Sample Center Drill" );
