    Question on intent of software for Mr. Smart

    dwf to dwg convert

    I have just had an experience with a similar issue. I use AutoCAD Civil 3D and received a DWF to insert. All of the converters that I have found will convert the DWF to a DWG with a catch. The DWF becomes an image in the DWG file that is created. I don't know if that is of any assistance...

    Incorrect label on report

    When I printed out a report for a local municipality, I noticed that I had chosen Paved Roads w/curbs & sewer for Type B soil. The CN is 98. The report shows that the area is 100% pervious. Should it not be listed as impervious? I don't know if any one else has seen this or not. I am...
