Express Tool users know the perfect solution to this problem is the FLATTEN command. I came across that very situation as I opened a drawing that was sent to me, and had linework drawn at many elevations. Regardless of the incredibly logical reasons behind the decision, it still doesn’t supersede the frustration of a missing tool. Since AutoCAD for Mac was a complete rewrite, and the Express Tools team has long been dissolved, it only makes sense Autodesk chose not to port Express Tools to the Mac platform. No matter how small the gap between platforms, a missing tool is a missing tool. While the gap between the Mac and Windows releases of AutoCAD 2011 left me wishing for more, the 2012, and especially the new 2013 release dramatically narrow the gap between the two platforms. In fact, my company and I are preparing to host an AutoCAD for Mac training class in the next month. Aside from being rather absent from the blogosphere, I have found myself using AutoCAD for Mac more and more lately.
