what is the importance of scale drawing?

Wow.  You need to do your own homework.

On a graph, these are the points where the line you are drawing crosses the "x" and "y" axis.  It's hard to give an example without drawing a graph, but you can see some here:\n\nhttp://www.tpub.com/math1/13a.htm

Basically when you are drawing a system diagram or describing a system you need to decide what is contained within the system and where its boundaries end to separate it from the environment. There are usually no right or wrong answers just different interpretations of the system. \n\nBasically the conceptualizing of a system is what you imagine is contained within the system and the boundary is what separates the system from the environment in which it exists.

If it is drawn 1:1, and you are scaling the drawing through printing, then try  print previews at those scales.  If it fits, then it's good.\n    If you scaled it when actually drawing it in cad, then follow juan4824's advice.  at a scale of 1:20, a line in CAD should measure 20 times LESS than the real life object it represents.  Example, a wall which is 20' in real life would measure 12"(1 ft) in CAD.  The same is true for 1:40 scale.  You can measure a line in Autocad using the DISTANCE command.  Type in DISTANCE, autocad will ask you to pick the first point.  Pick one point on the line.  The Autocad will ask you to pick the second point.  Pick the other point of the line.  Autocad will give you 4 distances.  The DELTA distance.  This is the one your interested in.  It gives you the linear distance along the line.  You'll also see X distance, Y distance, And Z distance.  The are lengths along various axis, and you're probaly not interested in these.\nHope this helps.  Good luck.

People usually don't do the Sun to scale when they do their model. They do it smaller. And they'll use distances between planets that are not to scale for the real distances from the sun.\n\nThat's the straight answer. Use artistic license, since using scale is not practical.

In Civil Engineering, it is always important to include a compass rose (or North arrow) and a scale (to show how the plan distance translates into actual distance) on each plan sheet.  Existing conditions need to be shown as accurately as possible.  The new design should be clear and well thought out.  Especially important is that each plan sheet is to be stamped and signed by a registered professional engineer.

dilation because it changes the size of the figure ... figures remain similar\n\nrotation, reflection and translation maintain congruence because all they do is change the position and/or orientation

Most of the free CAD drawings you are going to find are insertable blocks. CAD programs were originally intended for the engineering sect. However it is easy to create your own. Find a jpg or tif of a scene you like. \nThe following assumes you would be using AutoCAD...\nUse the "image manager" on the insert menu to select and insert your picture.\nAnother dialog box will pop up for insertion point, scale, and rotation with the following settings:\nInsertion point: Specify on-screen\nScale: X Y & Z all are 1\nRotation: Angle = 0\n...and click "OK".\nNow you should have your picture on the screen in AutoCAD.\nMake another layer & call it whatever you like. For the color use one that constrasts with the image.\nNow...all you do is start tracing it with lines and arcs.\nI've had to do this before when a client refused to provide the needed CAD files to complete the project. I had to send the drawing set out to Kinko's to get it scanned in tiff format. ...then traced over these to get the necessary scale drawings. It worked quite well.\nGood Luck!

The edges are anywhere that 2 of the surfaces connect.  If you are given enough information, say the coordinates of one of the corners and some combination of length, width, height, surface area or volume, you should be able to draw it in 3-dimensional space.

surface area, circumference, perimeter,and area are the important ones- for all figures- spheres, circles, cubes, etc.\n\nThat's just to start, you also want to make sure that anything you don't know or have trouble remembering is on that formula card.

geometry got its importance universally.in medical engg for \nthe study of the various instruments used their geometry is to be known.for eg:an optical fibre used in endoscopic surgeries must of very fine geometry,or else it cannot serve the purpose.\nstill many examples can be coated.

Accurate representation of angle and size. Some tests include: \nDistance from the center of projection to various points;\nOrthogonality of lines of lattitude and longitude;\nProportionality of areas;\nAzimuth angles between points, measured in all directions.\nThese tests are performed at many places on the map.\nAll projections have some distortion of scale and/or angle. Generally projections try to minimize one or the other, or compromise on both minimizations.\nSee the ref. for examples of projection types.

Well, almost every engineered product such as cars and bridges and rockets and even iPods require drawings to show how they're going to be made.  Even for 3D objects, those drawings are still largely 2D, and 2D geometry is indispensible in the development of those 2D drawings.  This is true even for computer workstations that work with 3D representation of products, because all the cross sections are still 2D, and engineers need those cross sections to help with the analysis.

A map's scale is a ratio that relates a unit of measure on a map to some number of the same units of measure on the earth's surface.\n For instance, a map scale of 1:25,000, tells us that 1 unit of measure represents 25,000 of the same units on the earth's surface. One inch on the map represents 25,000 inches on the earth's surface. meters or yards or kilometers or miles, respectively, on the earth's surface.

Cartographers have drawn many different kinds of maps, or projections. Each map projection is a different way of showing the round earth on a flat map. Drawing an accurate map gives cartographers a huge problem. It is impossible to draw a round planet on a flat surface without distorting, or misrepresenting, some parts of the earth. Each kind of map projection has some distortion. Typical distortions involve distance, direction, shape, and/or area.
