Hai, I want to segregate the entities of the current working design file into different files. I am able to create new files with an copy of the entities that belong to those particular files with the functions 1) mdlWorkDgn_read 2) mdlWorkDgn_write. The symbology and the propeties of the entities remains the same. Problem area is as follows : a) The current working design file is having a color table ( not the default color table). When creating the files, I am getting the color table as default color table. But I want to get the color table of the working design file. b) Also i tried with mdlColor_getColorTable which i got the color tablename of the working design file in the main function. And setting the color tablename with the function mdlColor_attachColorTable after the function mdlWorkDgn_write. When i do this, the colortable of the current working file is getting processed by this function and not the newly created design files. Help me in setting the colortable for the newly created design files as like the working design file. Help with suggestions, advice in advance is invited... Regards, M.Sworna Vidhya
