Pictorial Drawing
Term | Definition |
---|---|
axonometric projection | A form of projection that uses three axes at angles to show three sides of an object. |
cabinet oblique | The depth of the drawing is exactly one half of the true depth of the object. |
cavalier oblique | Shows the full depth of the object. |
dimetric projection | A form of axonometric projection in which the angles of two of the axes are equal; requires two special foreshortened scales to make measurements. |
isometric axes | Three axes spaced at equal angles of 120 degrees; used for isometric sketching and drawing. |
isometric drawing | A drawing in which the object is aligned with three axes that are equally spaced at 120 degree angles. |
isoplane | In AutoCAD, one of the three isometric plane orientations available for the cursor is isometric drawings. |
normal oblique | The depth of the drawing is exactly three quarters of the true depth of the object. |
perspective drawing | A three-dimensional representation of an object as it looks to the eye from a particular point. |
picture plane | In perspective drawing, the plane on which the object is drawn. |
technical illustration | A pictorial drawing that provides technical information using visual methods. |
trimetric projection | A form of axenometric projection in which all three of the axis angles are different; requires three special foreshortened scales to make measurements. |
vanishing point | The point at which receding axes converge in perspective drawing. |
