Python script for extracting information from Autocad block attributes in multiple documents.

• Uses package EZDXF Sequence of operations

1. FOR loop for checking unreadable files.
2. Define the function for extracting information from cad files.
   • Select Autocad block types and defines user-customised parameter for filtering between selected blocks.
   • For each attribute extracts tag information and value in a Python dictionary.
3. FOR loop to run the function on each file in the dxf file folder and return a Python dictionary.
4. Checks number of files read and number of files saved for discrepancy.
5. Pandas dataframe creation and excel export.
