Within general-purpose CAD packages, which types of editors are commonly included to modify geometric entities and reusable content efficiently?

Introduction / Context:
CAD environments provide specialised editors to speed up changes at multiple levels of detail—from individual vertices to entire libraries of reusable symbols and macros. Recognising these built-in tools helps users choose the most efficient editing approach for the task at hand.

Given Data / Assumptions:

• We are discussing general CAD systems (not niche plug-ins only).
• Editing tasks range from low-level geometry tweaks to high-level content management.
• Reusable content creation (macros/symbols/blocks) is a core capability.

Concept / Approach:
A point editor manipulates vertices and control points to adjust geometry precisely. A line editor handles line segments and polylines, enabling trimming, extending, or property changes. Macro and symbol editors (often called block or cell editors) let users define reusable composite objects with attributes and insertion rules, raising productivity and enforcing standards across drawings.

Step-by-Step Solution:

Verification / Alternative check:
Major CAD tools expose dedicated edit modes or commands for points/vertices, lines/polylines, and block/symbol editing, aligning with this classification.

Why Other Options Are Wrong:

Common Pitfalls:
Editing symbols directly in-place without updating the definition can cause inconsistencies; always manage library objects through the proper symbol/macro editor.

Final Answer:
All of the above.
