How Do You Determine The Orientation Of Orthographic Projections In A Multiview Drawing

Glass Box

November 8, 2022

Objective: will design and build a "glass" box from a flat canvass of transparency pic. You will so use your glass box to help y'all sketch orthographic projections of an object and create multiview drawings.

Procedure:

• Begin boosted cube nets. Sketch as many boosted cube nets equally you can call up of in your PLTW Technology Notebook or on orthographic grid paper. Avoid nets that are rotations or reflections of those already identified.
• Can you lot meet a design to the nets that will fold into a cube?
• How many squares are included in a cube cyberspace? Why is this always the case?

In that location are six squares that are included in a cube net. This is e'er the case, because at that place are 6 faces on a cube.

• What else is true about the arrangement of the squares in a cube cyberspace?

The arrangement of a the square in a cube net tin can't go in a direct line, and there tin can't be more than than 2 squares going in another direction.

• Put an X through your sketches that are non unique, that is, ones that are rotations or reflections of the nets you identified in step ane or sketched previously in step two.
• There should be at least six unique cube nets. Sketch whatever cube nets that you may have missed in step 2.
• Yous will utilize one of your cube nets to build a transparent "glass" box from transparency film. You will then place an object inside your drinking glass box and sketch all six orthographic projections of the object on the box.
• Remember that the orthographic projections of a multiview sketch are advisedly oriented with respect to the point of view shown by each. The principle multiview used in the United States (chosen third-angle project) provides orthographic projections bundled and aligned as shown in the following drawings.

Conclusion Questions:

one. How practice you determine the orientation of orthographic projections in a multiview drawing?

You lot can determine the orientation of the orthographic projections in a multiview

cartoon past where the drawing is positioned, whether its the front, back, top, etc.

2.How would you describe the geometric relationship that exists betwixt the adjacent views of a multiview drawing?

The geometric relationship that exists between the adjacent views of a multiview

cartoon is that they would all have the same dimensions.

3.Why is information technology important to lay out a multiview sketch with points and construction lines before you draw object lines?

    It is important to lay out a multiview sketch with points and construction lines before

you depict object lines because it helps tell whether it'due south in orthogonal or perspective

view.
