DRU Embedded in BRD file

Former Member

I noticed that v6.5.0 has the design rules (DRC rules) embedded in the file.  However, when I load the board, it doesn't use those values but rather the last specified DRU file.

1)  How can I use the embedded DRU parameters?

2)  How can I extract the embedded DRU parameters and create an external DRU file?

 

Thanks

    Actually, quite easy; when the Board is opened, its XML file can be

    read. A code example:

     

    string dr_name[], dr_value[]; int count;

     

    board(B) {

    // read the complete Board description and extract the designrules

     

       string brd_data, dr_lines[], par_list[];

       fileread(brd_data, B.name);

       xmlelements(dr_lines, brd_data, "eagle/drawing/board/designrules");

     

       // The designrules section sits in dr_lines[0]. Extract parameters

     

       count = xmlelements(par_list, dr_lines[0], "designrules/param");

     

       // extract name and value tag data into par_list

     

       for (int i; i < count; i++) {

         dr_name[i] = xmlattribute(par_list[i], "param", "name");

         dr_value[i] = xmlattribute(par_list[i], "param", "value");

         }

    };

     

    Now you have a list of the Name and Value pairs in the two string arrays.
