Modeling commands: which collection correctly lists AutoCAD 3D Modeling toolbar commands that can create or modify 3D solids?

Introduction / Context:
AutoCAD’s 3D toolset includes primitive creators and feature-creation operations. Recognizing the common commands accelerates modeling and reduces learning curve during concept-to-detail workflows.

Given Data / Assumptions:

• The question references the Modeling toolbar or panel.
• Standard 3D primitives and operations are available.
• We must decide whether each listed command belongs there.

Concept / Approach:
Box and Sphere are classic primitives that generate solids directly. Extrude converts closed 2D profiles (e.g., polylines, regions) into solids by adding depth. All are core parts of the 3D modeling workflow and reside within the modeling command sets.

Step-by-Step Solution:

Verification / Alternative check:
Open the 3D Modeling workspace: you will see Box, Sphere, Extrude available among other tools like Cylinder, Cone, Loft, and Revolve.

Why Other Options Are Wrong:

• box / sphere / extrude individually: True commands, but the most complete answer is that all are present.

Common Pitfalls:
Extruding open curves creates surfaces, not solids; ensure closed profiles for solids.

Final Answer:
all of the above
