在后处理里,把\UGS\NX 4.0\POSTBUILD\pblib\custom_command\pb_cmd_helix.tcl添加进去在程序头调用,输出线性还是整弧,自己设置变量. The following variable deines the output mode for helical records.
#
# FULL_CIRCLE -- This mode will output a helix record for each 360
# degrees of the helix.
# QUADRANT -- This mode will output a helix record for each 90
# degrees of the helix.
# LINEAR -- This mode will output the entire helix as linear gotos.
# END_POINT -- This mode will assume the control can define an entire
# helix in a single block.
