15. What is a polyline in AutoCAD, and how does it differ from a line?

A connected series of line or arc segments that are handled as a single object is called a polyline. Polylines, as opposed to individual lines, can be readily modified as a single unit and have varied widths and curved parts. They work well for drawing intricate borders and forms.

16. How can you edit a block after it has been inserted?

The BEDIT (Block Editor) command can be used to edit a block, allowing you to change its constituent parts. All occurrences of the block in the drawing will be updated by modifications made in the Block Editor. As an alternative, you can use the EXPLODE command to explode the block; however, this separates it into separate components.

17. What are grips in AutoCAD, and how are they used?

When an object is selected, little handles or squares known as grips emerge. They make it simple to change an object’s size, shape, or rotation. Grips offer a rapid and participatory means of adjusting without requiring the entry of particular commands.

18. What is the difference between the Stretch and Move commands?

The STRETCH command moves endpoints, vertices, or control points to change an object’s shape. It’s frequently employed to make portions of an object longer or shorter. In contrast, the MOVE command moves the object in its entirety from one position to another without altering its shape.

19. How do you create a text annotation in AutoCAD?

The TEXT and MTEXT commands can be used to produce text annotations. While MTEXT supports multi-line text with sophisticated formatting options, TEXT only produces single-line text. Using the Text Style Manager, you may adjust the font, size, and other characteristics.
