Feature classes are homogeneous collections of common features, each having the same spatial representation—such as points, lines, or polygons—and a common set of attribute columns, for example, a line feature class for representing road centerlines.
What is a feature class example?
A feature class is a collection of geographic features that share the same geometry type (such as point, line, or polygon) and the same attribute fields for a common area. Streets, well points, parcels, soil types, and census tracts are examples of feature classes.
What is a simple polyline?
A polyline is a connected sequence of line segments created as a single object. You can create straight line segments, arc segments, or a combination of the two.

Is a feature class A layer?
A feature layer is a layer containing a grouping of similar features and their associated properties. Feature layers are how ArcGIS Pro represents feature classes. They are the most commonly used layer type.
Why do we use polyline?
You can create straight line segments, arc segments, or a combination of the two. Some reasons you may choose to use polylines include the following: Vertices remain joined even after grip editing. Absolute line width (as an alternative to relative lineweight) that can be constant or tapered across a segment.
What is the command for polyline?
Creates a 2D polyline, a single object that is composed of line and arc segments. A 2D polyline is a connected sequence of segments created as a single planar object. You can create straight line segments, arc segments, or a combination of the two.

What is the difference between a layer and a feature class?
The feature class contains geographic features, such as buildings, parcels, cities, roads, and earthquake epicenters, and attribute information about the features. The feature layer is a part of the map or scene, and the map or scene is stored in the project.

What are polyline features in AutoCAD?
Polyline feature classes contain the vector geometry and descriptive attributes for the features you create. Polyline features consist of straight line segments, circular arcs, elliptical arcs, and Bézier curves created between vertices. You can create linear and curvilinear objects that have length but no area.
What is the relationship between a polyline and a polygon?
A polyline and an polygon cross if they share a polyline or a point (for vertical line) in common on the interior of the polygon which is not equivalent to the entire polyline. Only True relationships are shown in this illustration. Splits this geometry into a part left of the cutting polyline, and a part right of it.
