Civil 3d Alignment|Overview| Elements|Alignment Creating with Pi,Fixed,Floating&Free Method| Part 1

In Civil 3D, an alignment is a linear feature that represents a centerline or edge-of-pavement for a road or other transportation corridor. To create an alignment in Civil 3D, you can use the "Alignment" tool in the "Create Design" panel of the "Home" tab. This will bring up the "Alignment Layout Tools" dialog box, where you can specify the type of alignment (e.g. "Centerline" or "Baseline"), the alignment style, and the alignment data (e.g. layout points, tangents, curves, etc.). Once you have specified this information, you can create the alignment by clicking the "OK" button. Additionally, you can use the "Import/Export" feature to create an alignment using data from a spreadsheet or other external file
