Angle of elevation is the angle formed by the line of sight of an observer with the horizontal while he is viewing an object upward.The angle of elevation is a degree measure indicating the gradient of the line of sight. Angles of Elevation or Depression can be got using inverse trigonometric functions if the related lengths are known. Generally, an angle in the right triangle whichis the alternate interior angle of the angle ofdepression is considered for solving the problem.

When two positions are each viewed from the other position then, the angle of elevation from one point is equal to the angle of depression from the other point, as two angles are alternate interior angles. Now I can start drawing (but of course, I created some new layers) and project some lines down from the key points of the floor plan. I haven't designed a deck before, so I did what I normally do when I need information: I asked google.

If you looked at the plans, you would have seen that 4x4 posts are needed to support the deck. I check the code to see that the minimum height for a railing is 36 inches about the deck surface. Now I can add my hatch patterns to make the walls and chimney brick and add shakes to the roof.

Remember that elevations are a visual representation, so you can make them as detailed as needed.

Extra practice: Copy the floor plan to the left, then rotate it 90 degrees counter-clockwise. Elevation Church, led by Pastor Steven Furtick, has multiple locations in the Charlotte, NC area and beyond. As this angle can be measured using devices, this measure can be used to determine large heights and long distances, which are impractical to physically measure.Elevation of Sun is a degree measure similar to angle of elevation, which represents the the distance of the center of Sun's disk from the Horizon.

In the above illustration, you may note the alternate interior angle at the ground level.Even though we normally consider alternate interior angle for solving the problems, the angle of depression has to be shown different from this in the sketch. He traveled in the straight road leading to the mountain and measured the angle of elevation of the peak from a point A which is on level ground with the mountain base as 32?.

An exterior elevation might be used to show a home buyer what the front of their new home will look like, complete with bushes, bricks, and window trim.

You'll start with a floor plan and draw a front exterior elevation and an interior elevation. You will need to establish the overall size of the building and placement of windows and doors and other features.

Since my cabin is 24 feet wide and the roof is in the middle, this is an easy one to figure out. You can go a step further and add colors in a program like Photoshop (for an example, click here). There are not a lot of commands that are needed when creating elevations, but you need to learn how to use them wisely, and be fully aware of what you are drawing. Draw you projection lines down, then draw lines over from your existing elevation to get the heights.

Elevation of Sun is also used frequently in Right triangle model applications.In the above diagram Sun's elevation is marked as the angle between the line joining the Sun and the tip of the shadow and the horizontal. An elevation drawing is the view that you would see in real life as you stood on the floor or ground and looked at the wall. Another example is an interior elevation drawing to show a contractor where finishes and items are to be used. The techniques will be the same, but the difference will be in the detail that you provide.

I am going to make my wrap around to the side and make it larger to accommodate a table, hairs and a bar-b-que.

My usual rule for detailing elevations is to add detail first to the objects 'closest to you'. So I drew a line down from the center of the fireplace (notice the small circle for the flue?) and then offset it to make a 18 inch wide chimney. Later on if you start drawing 3D, you can create rendered images that look almost photographic, but for 2D work, elevation drawings do a great job.

These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles.In the above picture a man standing on a cliff is simultaneously viewing an airplane flying in the sky and a boat sailing in the lake beneath. The first example would be quite detailed, while the second would be more basic (but might contain dimensions). For this exercise we are going to use the Cabin drawing that you might have drawn earlier in this level.

You will need to figure these out (I'll help!) and you will also have to design the exterior materials.

Then I will rotate the drawing so the the side that I'm drawing the elevation of is pointing down. In this case, you want to draw a line that represents the top of the foundation that the cabin sits on.

I've added in a hidden line to show where the wall is, but this is only for reference and will be erased.

Have a look at it and start thinking about what the cabin might look like from the outside.

To draw this is just a simple matter of offsetting and then trim the objects 'behind' the deck railing.
