Use the Inquiry Tool to run inquiries on Autodesk Civil 3D objects. You can extract information from the design model to aid in design, validation, and analysis. See About Inquiry Typest for a list of available inquiries.
The Inquiry Tool is in a window you can keep open on screen while you do other work. Like the Toolspace, you can dock the window or turn on the AutoHide feature so it displays only when you move your mouse over it to save desktop space.
The Inquiry Tool consolidates and replaces some of the listing and inquiry commands that were in previous releases of Autodesk Civil 3D.
