Computer Aided Drafting Questions and Answers

Answer: A

The command is MOVE.

In AutoCAD, MOVE relocates selected objects from a base point to a second point without changing their size or orientation. The original is not left behind.

COPY places a duplicate and keeps the original in place, PASTE inserts content from the clipboard, and OFFSET creates a parallel copy at a set distance.

Answer: D

The one not applicable is array modeling.

Geometric modeling in CAD is done in three ways: wire frame models of edges and vertices, surface models that add the faces, and solid models that represent the complete volume.

An array is an editing command that repeats an object in a rectangular or polar pattern; it is not a modeling scheme.

Answer: D

The command that does not belong to 2D drafting is Extrusion.

Extrude (extrusion) is a 3D modelling command in AutoCAD: it takes a closed 2D profile and sweeps it through a height or along a path to create a 3D solid or surface.

Circle draws a 2D object, and Trim and Extend are 2D editing commands that cut an object back to a boundary or lengthen it to meet one. All three are used constantly in ordinary 2D drafting, which is why they are the wrong choice here.
