How to Draw Linear Dimensions on Paper
The basic idea of drawing linear dimensions is that of representing a piece of metal or other material on a flat surface. This is not the only meaning of linear dimensions, but it is the commonest and most common one. However, the concept is not limited to merely representing metal, but also other material, like glass.
There are many other ways to represent linear dimensions on a sheet of paper. For instance, when you have a part that you want to AutoCad Homework Help, all you need to do is get some paper, pencil, eraser, and ruler, and you will be good to go.
But what if you do not have a drawing paper available? You can always use a digital drafting pen, which is quite similar to a drafting pencil, except that it has a digital LCD screen on it.
Metal drafting pens have very fine points, which are much like those of a pencil, only more refined. They are great for detailed work, or for thin sections of metal.
You should always start by surface preparation. Use a clean sheet of paper to start with, and start with an outline. Draw a square on the middle of the paper, this will make your portion look larger than it actually is.
You should then use vertical and horizontal guides to make a grid like pattern in the middle of the page. Using these guides, draw a cross section to create the linear dimension. Then draw an outer circle using the vertical guides, to create a top section of the part.
Once you have made the cross section and created the top portion, it is now time to draw a solid sketch. Draw a straight line from the cross section, to the outer circle, this is called the axis. Draw another vertical and horizontal line to form the outer surface.
When you draw the center of the part, draw a dot in the middle, use a pencil to guide you. Continue along a similar path until you reach the center of the part, again you will need to use the pencil to keep the section straight.
Now, draw a rectangle right next to the cross section, using the horizontal and vertical guides. Then, use the axis again to draw a solid line in the corner of the rectangle.
Finally, draw a semi-circle in the middle of the axis, again using the horizontal and vertical guides. The lines will run across the circle. Try this with two parts and see if you can make them fit together without any gaps.
Draw a single part using these methods, this will be a click design tool. You should always ensure that you have the part being drawn at the correct size. If you are doing a part that will be more than one-sided, you should draw two pieces, each with a different size.
With the two parts of the part together, it will be easier to create a similar shape. Then, align the two parts so that they will fit together, and draw a solid horizontal and vertical line down the length of the part.
