    PDF to Vector

    I've used Inkscape in the past. It's free and open source and available for mac, PC and Linux. You can take a PDF or even a jpeg and convert it to a vector format. Then you can save it as a DXF file which is able to be opened by AutoCAD.

    Compiling an shp file

    OK. We're getting closer. Last try...I promise. *2,13,SINE 11,(97,159,0,1,-044),11,(97,159,0,1,044),0 *3,10,SINE1 13,(5,0,-95),(5,0,95),(0,0),0 The fractional arc form has some unexpected behavior. It seems like the offset from the octet boundary is measured dependent on the direction of the...

The sine wave is just a circle arc above the line followed by an arc below the line. Based on all the reading I've done, I'll need to create an shp file defining the...

    Utility P&ID Sample

    When I worked for Cargill, their utility P&IDs would have several rectangles on each utility page labeled with a standard P&ID page number and show the pipes entering or leaving (see attached example). The PIP does not mention anything like this and probably suggests using utility connectors...

    Utility P&ID Sample

    I'm working on developing P&IDs for a large facility that I work at. I have the sample of the PIP P&ID standard and I've been following that as closely as I can for the main processing areas. However, the sample document does not contain the Utility P&ID sample. Does anyone have a Utility...

    I saw the question above: >Hmm... I'd be interested if anyone knows of any plants burning fuel ethanol in the boilers of their ethanol plants!:) and had to post the following piece from the air permit of a Kentucky bourbon distillery: -----------begin snip------------- Emissions Unit 08...
