Forum Post: How do you get the prop.xx file when creating a techlib in nograph mode?

I am creating a new techlib and compiling an ascii techfile into it using the core code of ddCreateLib(), techOpenTechFile(), and tclLoadTechFile() from the attached solution. However, I get very many warnings about the prop.xx file missing when opening the final layout in graphics mode. The solution description says explicitly that it does not create the prop.xx file and to copy it from somewhere. Where should the prop.xx file be copied from if it is not specific to a techlibrary? Since prop.xx binary, the contents are unknown, to confirm a random copy from another library is ok. Alternatively, is there another way to create a new techlib and compile a techfile in nograph mode that would generate the prop.xx file? support.cadence.com/.../ArticleAttachmentPortal ;pageName=ArticleContent&sq=005d0000001T5b7AAC_2017111103018741
