The developers clearly understand that engineers don’t want to learn GIS—they want GIS to come to them. And with PE4, it finally has. Subtract one point for the learning curve and

You only need occasional aerial imagery (use Snipping Tool + Align command), you already use Civil 3D with its Map 3D tools (though PE4 is more intuitive), or you’re comfortable using QGIS alongside CAD (free, but slower context-switching). You can draw a line in CAD, tag it with GIS attributes (e
