I am not sure precisely for how long, AutoCAD automatically scales incoming blocks from, for example, Architectural units to Feet. More Information and Background (if desired) Survey feet as a block scaling factor, and any difference between a receiving drawing and an inserted drawing will cause AutoCAD to scale the incoming drawing WITHOUT warning.

Why?ĪutoCAD 2017 and above recognizes U.S. This works well, regardless of INSUNITS settings, when both AutoCAD Civil 3D or AutoCAD Map drawings are established on a good Geographic model reference.

Either your working drawing or the reference drawing’s INSUNITS setting is set to 0įigure 1: Note the “Locate using Geographic Data” option in the above xref insert dialog.

Both drawings use the same INSUNITS setting.

Please check and verify that either of the following is true BEFORE using a reference drawing (including blocks and xrefs): Due diligence by all parties caught the difference and we corrected it rapidly. The site is thousands of feet long, and as many of the old references were not shown, I did not identify the problem immediately. When the latter was reintroduced to the former, they did not match.

Recently I was involved with a 2016 drawing that went out with INSUNITS = 2 (feet), and after being worked with by others, returned as INSUNITS = 21 (U.S. What Went Wrong with AutoCAD Civil 3D INSUNITS Scaling We always verify key distances after an insert or xref is added. This is generally understood, but can be an occupational hazard. If one is set to Feet and another Inches, the system will scale accordingly. AutoCAD automatically scales incoming blocks and external references (xrefs) to match the receiving drawing, according to their INSUNITS settings. AutoCAD Civil 3D INSUNITS Scaling problems are becoming evident as pre-2017 drawings are referenced with newer versions.
