Line, is a basic command as a single line that can form into an object. However, this command can not be formed into three dimensions. To shape it needs to change the structure of the line to polyline

There's no such thing as "BIMS" in AutoCAD. You may be confusing two terms: BIM = Building Information Modeling (a process made primarily in Revit, not AutoCAD) AutoCAD = 2D/3D drafting software (Computer-Aided Design) AutoCAD is used for traditional drafting, while Revit (also by Autodesk) is designed specifically for BIM workflows. However, AutoCAD files can be imported into Revit for BIM projects, and some teams use both tools together. If you're asking about BIM software, Revit, ArchiCAD, and Navisworks are the industry standards, not AutoCAD.
In AutoCAD, drawing files typically use the extension ".dwg." This format is the standard for storing two and three-dimensional design data and metadata. AutoCAD also supports other file formats, such as ".dxf" (Drawing Exchange Format), which is used for interoperability between different CAD software.
Is AutoCAD better than Revit? Not necessarily it depends on your project needs and industry. Both are excellent Autodesk products, but they serve different purposes: AutoCAD is CAD software primarily used for 2D drafting and detailing across many industries Revit is BIM software designed specifically for building design, documentation, and collaboration throughout the entire project lifecycle AutoCAD is versatile and general-purpose, making it ideal for smaller projects, precise 2D plans, and teams that need a shorter learning curve Revit excels at large-scale, multidisciplinary projects where collaboration is critical, creating intelligent 3D models where changes automatically update across all views (plans, sections, elevations) Revit integrates architecture, structure, and MEP into one unified model, reducing errors and improving coordination between disciplines AutoCAD requires manual updates and is better suited for individual work or less complex collaboration workflows Revit is more future-proof for data-rich building practices, lifecycle management, and BIM requirements that are becoming industry standard AutoCAD is more cost-effective for traditional 2D drafting tasks and companies with legacy workflows Many firms use both programs together AutoCAD for detailing and legacy work, Revit for BIM deliverables and collaboration since they are interoperable and work seamlessly together The bottom line: Revit is better for BIM and collaborative building projects, while AutoCAD is better for traditional 2D drafting. Neither is universally "better" your choice should match your specific needs and project requirements.
The correct title for an AutoCAD draftsman can vary based on the specific role and industry, but common titles include "CAD Technician," "CAD Designer," or "Drafting Technician." In some organizations, they may also be referred to as "Architectural Drafter" or "Mechanical Drafter," depending on their specialization. These titles reflect the professional's skills in creating detailed drawings and plans using AutoCAD software.

This command is used to create single line text in drawing
There is a command line at the bottom of the screen. This is where the prompt is to type in commands.
type REFCLOSE at the command line
A polyline is a line composed of many segments: for example the rectangle is a polyline consisting of four line segments.
Type ml in the command line.

The red lines in an AutoCAD drawing indicates the error that could be geometrical or duplicate objects. Generally, every AutoCAD drawing go through several revisions, at that time the highlighted red lines are looked for edits to remove the errors with their best alternatives.
Most designers would use Autocad.
