AutoCAD Commands and Objects Quiz

Adds dimensions to objects in a drawing.

Used to change layer properties like color and line type.

Starts a new drawing file.

Change the color of an object using layer properties.

Creates a smooth curve through points.

The standard file type for AutoCAD drawings is .dwg.

Not a conic section; formed by a line rotating around a fixed point or axis.

Created by the intersection of a plane and a cone.

A point from which all points on the parabola are equidistant.

Greater than 1 in a hyperbola.

The line passing through the center and parallel to the asymptotes.

A line parallel to the axis of symmetry in a parabola.

The distance from any point on the curve to the focus is equal to the distance from the point to the directrix.

The sum of the distances from any point on the ellipse to the two foci is constant.

A line on the Horizontal Plane (HP).

A projection of the plane onto the plane of projection.

Appears as a line in the front view (VP).

Projects as a line parallel to the inclined edge.

Appears as a polygon.

Use an auxiliary view perpendicular to the plane.

Projects as a line.

Visible only in a view perpendicular to the plane.

Projects as a straight line in both views.

Combination of views to represent a solid object.

A method of representing a 3D object in 2D where the top view appears above the front view.

When a plane is parallel to the Vertical Plane (VP) and perpendicular to the Horizontal Plane (HP), its projection on the HP will be a straight line.

A drawing method that uses multiple views (typically three) to represent a 3D object in 2D. Each view shows a different face of the object.

When a rectangular block is inclined to the Horizontal Plane (HP) in orthographic projection, its top view will still be a rectangle, but it might be elongated or foreshortened.

A type of 3D projection where the object is viewed from a corner, with its three axes at 120 degrees to each other. Lines parallel to the axes are drawn in their true lengths.

The three axes in isometric projection are at 120 degrees to each other, allowing for a 3D representation of an object.

The front view in an orthographic projection is placed directly above the top view and to the right of the side view.

Orthographic projection is advantageous because it shows the true size and shape of the object's features.

The process of unfolding a cylinder into a flat, two-dimensional shape.

The process of unfolding a pyramid into a flat, two-dimensional shape, consisting of triangular sectors arranged around the apex.

The process of unfolding a right circular cone into a flat, two-dimensional shape, resulting in a sector with a radius equal to the slant height of the cone.

The process of unfolding a hexagonal prism into a flat, two-dimensional shape, consisting of six rectangles and two hexagonal faces.

The process of unfolding an open box with rectangular faces into a flat, two-dimensional shape, resulting in a combination of squares and rectangles.

The distance between views in orthographic projection depends on the object's size.

Isometric projection shows all three dimensions with equal foreshortening, meaning they all appear smaller.

Orthographic projection uses front, top, and side views to show the 3D shape.

Hidden details in orthographic projections are shown using dashed lines.

Front, top, and side views are arranged specifically in orthographic projection to reveal the object's 3D form.

Surface development is the process of unfolding a 3D object into a 2D plane, like laying out a pattern.
