Step 1: Understanding the figure.
The figure shows an object (profile line) being extruded along a straight vector direction to generate a 3D mesh surface.
Step 2: Command functions in AutoCAD.
- TABSURF: Creates a tabulated surface by sweeping a curve along a straight path (direction vector).
- REVSURF: Revolves a curve around an axis to create a surface of revolution.
- RULESURF: Creates a ruled surface between two curves.
- EDGESURF: Generates a surface using four boundary curves.
Step 3: Matching with the question.
Since the task involves sweeping a profile along a straight path, the correct command is TABSURF.

Match the position of feet in Group I to the most appropriate description of stability of human body in Group II.
Group I
P \(\text{Position 1: Feet slightly apart in parallel}\)
Q \(\text{Position 2: Feet apart in a wide stance}\)
R \(\text{Position 3: Feet close together with a narrow stance}\)
S \(\text{Position 4: Feet in a wide cross stance}\)
Group II
1 Stable antero-posteriorly
2 Laterally stable
3 Fairly stable in all directions
4 Vertically stable
5 Unstable
