thanks Fom.
you're right.
I have gds importing problem.
so I guess that the problem is occured by not installing "Technolgy file" menu.
my problem is as fallows.
I make library with Tech File supplied by Foundry.
the tech file includes the layer definition of layout file.
atfter making library, I import gds files which is exported from @gilent @DS. but layout is not imported its exact layer.
for example, the stream layer definition is same . but cadence layer definition is different from tech file definition. And Cadence purpose of the layer is not drawing , but P0(???)
please tell me how to solve this.
