I would never convert a survey originally drawn in feet and create a duplicate drawing that uses feet-and-inches. If I did, the surveyed coordinates, the x/y’s, would get messed up.

 

In a survey the coordinates are golden (the typical US survey is in feet). Believe it or not, modelspace represents the earth's surface while surveyed coordinates represent real world 'points' on that same surface. You want the points or the x/y’s, in the survey to be honored. If they're not, then you or your boss, just paid a licensed surveyor unnecessarily. And don’t forget, you paid that surveyor to 'get it right' not to 'get it close!'

 

Your feetinserttoinchesmakeblockxref procedure is whacky. Why? Because you've taken your 1st drawing, a survey feet drawing, scaled it to inches in a 2nd drawing, then inserted the 2nd back into the 1st. Aaahh…..excuse me while I climb back into my chair.....I got so dizzy typing it I accidentally fell on the floor.

 

You need to expand your drawing repertoire and draw in feet instead of drawing in feet-and-inches. If you feel compelled to use feet-and-inches anyway, be forewarned, your Bing aerial imagery will no longer be consistent with your line work. Yes, you can make Bing aerial imagery appear as a basemap in the original Survey Drawing if know how to assign the same coordinate system used by the surveyor.

 

<<Sidenote: If you want to know how to turn on Bing Aerial in the survey you uploaded, start a new thread titled How to Turn on Bing Aerial Imagery in a Survey Drawing so it’s Consistent with my Line Work.>>

 

To make the paste procedure work accurately, abandon your procedure and do this instead:

  1. Open the survey drawing. Type UNITS on command line and change the units to UNITLESS.
  2. While still in the survey, perform a Save As (You make a COPY w/Save As because you want the original survey to remain as-is). When you save it, keep the same name as the original but add an underscore version 2 as a suffix, like this *_v2.   
  3. Next while still in *_v2, SELECTALL=>Right Click=>SCALE=>base point enter 0,0=>scale factor enter 12=>ENTER
  4. Pan and Zoom to the newly scaled objects=>Select all the scaled objects=>Right Click=>Clipboard=>Copy to Clipboard=>base point enter 0,0=>ENTER
  5. Next, go to your ‘inches’ drawing such as TEST FILE A – Inches.dwg, the drawing you uploaded in a previous post=>Right Click in modelspace=>Clipboard=>Paste to Original Coordinates (or Paste as Block).
