CMT add-in tool
Corridor multiple targets (CMT) is an add-in tool for Autodesk Civil 3D 2018, 2019 and higher. This tool attempts to simplify targeting of complex corridors using text filters and using entity selection directly in the model space. You don't need to switch between object types when targeting to an alignment, feature line or line.
You can easily setup multiple parameters for different regions, subassemblies and even baselines. A plain dialog box completely replaces the standard Civil 3D dialog and simplifies it substantially. The dialog is floating (non-modal), so you can freely move in model space when setting targets, not needing to close the dialog. In this way, you can easily watch the results of your design work.
