What is a PI in Civil 3d?

What is floating curve Civil 3D?

Add a floating curve, defined by a specified radius and angle range, from an existing entity to a specified end point. This curve supports both compound and reverse solutions.

What is PC and PT in Civil 3D?

PC=Point of curvature (Begin curve). PT= Point of tangency (End curve).

How do I remove a point from an alignment in Civil 3D?

In Toolspace, on the Prospector tab, select the alignment object. Right-click. Click Delete.

What is a site in Civil 3D?

The Civil Site Design pipe designer, provides a powerful interface that displays pipes in relationship to the ground surface. Pipes are designed automatically based on minimum slope and design flows. Obstructions from other utilities are displayed and color coated based on minimum clearances.

How do you fillet an alignment in Civil 3d?

Click the alignment. Click Alignment tab Modify panel Geometry Editor Find. On the Alignment Layout Tools toolbar, click Free Curve Fillet (Between Two Entities, Radius). Specify the entity (line, curve) from which you want to add the free curve.

How do you reverse a curve in Civil 3d?

Click Home tab Draw panel Curves drop-down Create Reverse Or Compound Curve Find. Select the arc object nearest the end to which the new compound or reverse curve is to be attached. Specify whether to create a Reverse or Compound curve.

What is PC in an alignment?

You can use the At Alignment Geometry command to create a point at every geometry point on an alignment. Geometry points are points of curvature (PC), points of tangency (PT), spiral-curves (SC), curve-spirals (CS), tangent spirals (TS), spiral-tangents (ST), and points of intersection (PI).

What is point of compound curvature?

The point where the two curves connect (namely, the point at which the PT of the first curve equals the PC of the second curve) is referred to as the point of compound curvature (PCC). Since their tangent lengths vary, compound curves fit the topography much better than simple curves.

Can you trim an alignment?

After performing a multiple or pairwise alignment, you may wish to trim off one or both ends before realigning, saving or exporting.
