padstack, package symbol文件的位置

生产netlist的时候出现warning, 原因是无法load一些padstack文件
#1   WARNING(SPMHNI-192): Device/Symbol check warning detected.
WARNING(SPMHNI-337): Unable to load symbol 'SMDCAP0805' for device 'CAP NP_SMDCAP0805_CAP NP': WARNING(SPMHUT-127): Could not find padstack R155_135.

系统只在如下的路径里寻找这些文件:
MODULEPATH =  .
           C:/Cadence/SPB_16.3/share/local/pcb/modules
PSMPATH =  .
           symbols
           ..
           ../symbols
           C:/Cadence/SPB_16.3/share/local/pcb/symbols
           C:/Cadence/SPB_16.3/share/pcb/pcb_lib/symbols
           C:/Cadence/SPB_16.3/share/pcb/allegrolib/symbols
PADPATH =  .
           symbols
           ..
           ../symbols
           C:/Cadence/SPB_16.3/share/local/pcb/padstacks
           C:/Cadence/SPB_16.3/share/pcb/pcb_lib/symbols
           C:/Cadence/SPB_16.3/share/pcb/allegrolib/symbols

如果这些文件(padstack, package symbol)都在工作目录下，那可不可以添加工作目录到这些路径下，否则的话岂不是所以的.pad .psm文件都要复制到这些路径指定的文件夹内?
谢谢

如果这些文件(padstack, package symbol)都在工作目录下，那可不可以添加工作目录到这些路径下。是可以的！

如何添加呢

setup-user preferences -paths-library

是这样
