Snaps to a point perpendicular to an arc, circle, ellipse, elliptical arc, line, multiline, polyline, ray, region, solid, spline, or xline.
TANgent
Snaps to the tangent of an arc, circle, ellipse, elliptical arc, or spline. Deferred Tangent snap mode is automatically turned on when the object you are drawing requires that you complete more than one tangent snap.
NEArest
Snaps to the nearest point on an arc, circle, ellipse, elliptical arc, line, multiline, point, polyline, ray, spline, or xline.
APParent Intersection

OBJECT SNAP MODES
rev. 01/10/2022
PARallel
Constrains a line segment, polyline segment, ray or xline to be parallel to another linear object. After you specify the first point of a linear object, specify the parallel object snap. Unlike other object snap modes, you move the cursor and hover over another linear object until the angle is acquired. Then, move the cursor back toward the object that you are creating. When the path of the object is parallel to the previous linear object, an alignment path is displayed, which you can use to create the parallel object.

ORTHOGRAPHIC PROJECTION
There are two fundamental principles of orthographic projection, these are:
This can be simplified by using the “Glass Box” concept:
A glass box, consisting of six glass planes, can be placed around a three dimensional object. Each side of the 3-D object can be projected onto each of the glass planes so that an observer line of sight is perpendicular to a plane. If we think of the intersection of each of the glass planes as folding lines that can rotate, then we can open up the box so that each of its planes open up into a single two dimensional planes. It depends on the sequence in which we open the box on where the view planes will be located. In the United States we open the box in the third angle projection. Third angle projection results in the top view being placed above the front view, the right side view being placed to the right of the front view, the left and rear views placed to the left of the front view, and the bottom view placed below the front view.

Fig.4 In this case, orthographic views are shown of the front, top, and right side views. These are known as the principal views.
Figure 4 shows the principal views shown on their orthographic planes. These views are then rotated into a two dimensional plane with the front view. When the views are in a two dimensional plane we can fully describe their shape and size.
Fig.5 The six views of an object. The principal views are the Top, Front, and Right Side.
40 rev. 01/10/2022
The table below provides us with information in which views we can find the object dimensions.
These dimensions can be seen in the isometric projection for the object we have used in previous examples.

There are three surface types that we need to be able to recognize, these are:
The following table will help you to remember the above definitions

The rules of orthographic projection can be simplified to the following three rules:
Finally, we need a method that we can follow each time we solve a problem:

ARC TOOLS
The ARC tools are located on the Draw panel of the Home tab. There are several different ways to draw arcs, all require the selection of 3 points or 3 pieces of information. Arcs are drawn counterclockwise.
3‐POINT: Any three points will define the arc. The command asks you to identify a START point, a SECOND point which the arc passes through and the END point.
START, CENTER, and END, ANGLE or LENGTH These commands require input of the START point, and then the CENTER point of the arc. The third parameter determines the length of the arc by specifying the:
START, CENTER, END START, CENTER, ANGLE START, CENTER, LENGTH ENDpoint of the arc Included ANGLE chord Length
69 rev. 01/10/2022
START, END, and RADIUS, ANGLE, or DIRECTION This group of tools require the input of the START point followed by the END point. The third parameter can be:
START, END, RADUIS START, END, ANGLE START, END, DIRECTION The RADIUS is the distance Included ANGLE The direction of a line from the center to the arc tangent to the start point
CENTER, START, and END, ANGLE or LENGTH These commands are similar to the START, CENTER…group, but requires input of the CENTER point first, and then the START point of the arc. The third parameter determines the length of the arc by specifying the:
START, CENTER, END START, CENTER, ANGLE START, CENTER, LENGTH ENDpoint of the arc Included ANGLE chord Length

ISOMETRIC PROJECTION
The term “isometric” comes from the Greek for “equal measure”, reflecting that the scale along each axis of the projection is the same. An isometric view of an object can be obtained by choosing the viewing direction in a way that the angles between the projection of the x, y, and z axes are all the same, or 120°.
Start with an origin point and draw lines representing width and depth at 30° angles. These are called isometric lines.
Create a 3-D isometric box. Establish width, height, and Depth.
Place normal surfaces on each face of the 3-D box.
Finishes drawing other surfaces and remove unwanted lines.
