DWG keeps ‘Scanning the drawing’ between every command

For some time now, AutoCAD Civil 3D along with other Autodesk products have had an issue where the drawing keeps continually scanning every time you use a command i.e. MOVE, ZOOM, LINE etc… The progress bar may run several seconds or even minutes during the scan, so you can see how irritating this can be.

I’ve seen this issue fixed with a PURGE a couple of times, as well as as not fixed with PURGE a couple of times.  The fix I’ve seen work consistently is to change the system variable of SHOWLAYERUSAGE from 1 to 0.

I hope this quick fix saves you some time and effort.
