Problem reading pdf of CAD drawing.


Badge +2

Hi. I'm trying to read a pdf of a 2D CAD drawing. The file opens ok in Microsoft Edge browser but when I use the Adobe Geospatial PDF reader it is only reading a fraction of the elements in the file - a few text elements.  I've tried playing around with the reader parameters but cant figure out why its not reading the whole file. Any idea what i'm doing wrong?

Hi. Yes you can download it from this site. Its plan 08 in the "Materials" section.

Your pdf file contains raster features. If you zoom in you can see the pixels.

The purpose of the challenge you pointed to is to find ways of converting "From old drawings to vector graphic".

There even are a few solution posted for converting them via FME.

Ok thanks yes I can see now that one of the features is a raster. But all the band values - RGBA are 0 so its not visible. Any idea how to fix that?
