Does anyone know of any free software downloads for LT that will convert raster images to vector?  (Ex:  black and white scanned property boundary converted to polylines)
Also, are there any downloads to paste excel charts into Autocad LT as autocad entities?

I know Vectornow-Raster to Vector Converter and download it from here: http://www.autodwg.com/vectorNow.htm
it is not a freeware but worth a try. It can convert raster images to vector. You can simply copy and paste the excel charts as OLE into acad.In Microsoft Excel, select the spreadsheet area that you want to import, and copy it to the clipboard. In AutoCAD, on the Edit menu, click Paste Special. In
the Paste Special dialog box, select the AutoCAD Entities option. This
will create an AutoCAD table that can be formatted to match the
linetype and text style.

You may take a look at Vextractor raster to vector converter. It work good enough, especially on noised scan drawings.
