Here lurk gremlins

Years and years ago I included a routine in my data collection software to automatically draw a saguaro cactus to scale. Nothing to it, really: SAG9 will draw a saguaro 9 feet tall, with the cross at the bottom the horizontal location.

Today I was collecting elevations on a site and came across two transplanted saguaros, so I located them. When I ran the file into AutoCAD they both drew something like 30 feet tall instead of 5 feet. Now why would something that has run perfectly for decades do a fizzle? Ah, usually I do the horizontal first, then the grid elevations and break lines. I located these saguaros while getting grid shots, and I didn't want to plot the elevation, so the code was NOEL/SAG5. For whatever reason, the culprit was NOEL plus SAG, lurking all these years and just waiting for the right combination of descriptors.

So, let me get this straight. A routine that I am figuring You wrote, you are now saying has (now had) a gremlin. Which makes you a master gremlin if I got the sequence correct? 😀

I now know what I did years ago. I often have multiple codes/descriptors at one point, such as: B CURB/B SWK. I knew that a saguaro descriptor would always stand alone because nothing would ever connect to a saguaro, so it couldn't handle the NOEL/SAG5 coding. The lesson learned is never say never.

I was just about to start a gremlin thread, but saw this one, so here goes. This morning I'm merrily drafting away, then get a phone call. Then get asked to set up a transmittal for a plan we finished last week. So I write the transmittal in Word, and print it out. Open the PDF of our plan in Adobe and print 6 copies to a large format Xerox plotter. While waiting for the Xerox to do it's thing I sit back down to my computer and notice that AutoCAD has a pop up message saying "Plot and Publish Job Complete". I open up the details and it displays:

Job: - Plotted
Job ID: 1
Sheet set name:
Date and time started: 6/19/2017 10:49:50 AM
Date and time completed: 6/19/2017 10:49:51 AM
UserID: plothian
Profile ID: Carlson2016
Total sheets: 1
Sheets plotted: 1
Number of errors: 0
Number of warnings: 0
Sheet: - Plotted
File: G:Carlson Jobs24974Dwg24974 SRV-WP.dwg
Category name:
Page setup:
Device name: Canon iPF785
Plot file path:
Paper size: 24"x36"(ARCH D)

The thing is, I never sent anything to the Canon plotter this morning. Check the plotter tray, and sure enough, nothing plotted from my drawing. I check the command history, and there is nothing there about sending a plot. The only thing that happened since taking my phone call is a couple of autosaves, since I forgot to hit qsave before moving on to my other errands. Very weird.

And I found the gremlin. A coworker jumped on my computer to plot a drawing while I was off to see the Xerox machine, made here plot, then closed the drawing so I would not see anything in the command line history. Mystery solved.
