ISOMETRIC SKETCHES

• What angle do isometric axes make with each other?

• What angle do isometric axes make with each other?• 120 degrees

• What are isometric lines versus non-isometric lines? What type of edges would you draw with both

• What are isometric lines versus non-isometric lines? What type of edges would you draw with both• Isometric lines are parallel to the isometric axes and are used to

draw normal edges• Non-isometric lines are NOT parallel to the isometric axes and are

used to draw inclined and oblique edges

• Explain the offset location measurement method. What types of surfaces would you draw using this method?

• Explain the offset location measurement method. What types of surfaces would you draw using this method?• Method used in isometric drawing to locate points with respect to

each other using rule of parallelism. Normal, inclined, and oblique can be drawn using this method.

• True or False. A 30, 60, and 90 degree angle triangle is shown on a multi-view. The same angles will transfer directly to the isometric view.

• True or False. A 30, 60, and 90 degree angle triangle is shown on a multi-view. The same angles will transfer directly to the isometric view.• FALSE. None of the angles will be the same in the isometric view.

Locate the points of the triangle using dimensions rather than using angles when drawing the isometric view.

• True or False. Hidden lines and centerlines are used in isometric Drawings

• True or False. Hidden lines and centerlines are used in isometric Drawings• FALSE (or True in a way?) Hidden lines and centerlines should be

used sparingly. If in doubt, leave them out.
