## Do auxiliary views have hidden lines?

Generally, hidden lines should be omitted in auxiliary views, unless they are needed to clearly communicate the drawing’s intent. For practice, show all hidden lines, especially if the auxiliary view of the entire object is shown.

## What is a partial auxiliary view?

Partial Aux views Partial auxiliary view In auxiliary views, it is normal practice not to project hidden features or other features that are not part of the inclined surface. When only the details for the inclined surface are projected and drawn in the auxiliary view, the view is called a partial auxiliary view.

**What are the six types of auxiliary views?**

Auxiliary views are used to find: 1) true length of an inclined or oblique line; 2) true size and shape (TSS) of an inclined or oblique face 3) edge view of oblique face; 4) point view of inclined or oblique line; 5) true size and shape of features on incline or oblique faces.

**What does an auxiliary view show?**

An auxiliary view is simply a “helper” view, which shows the slanted part of the object as it actually is. It turns, or projects, the. object so that the true size and shape of the surf ace (or surfaces) are seen as they actually are. Auxiliary views are commonly found on many types of industrial drawings.

### Why is auxiliary view important?

An auxiliary view is a projection on an auxiliary plane that is parallel to an inclined (slanting) surface. It is a view looking directly at the inclined surface in a direction perpendicular to it. Auxiliary projections are important for describing the true geometric shapes of inclined surfaces.

### What is the difference between a complete auxiliary view and a partial auxiliary view?

What is the difference between a complete auxiliary view and a partial auxiliary view? Complete auxiliary views show all of the part. Partial auxiliary views show only that information which adds to the description of the part. It is characterized by a break line, to eliminate unnecessary information.

**What is a secondary auxiliary view?**

The secondary auxiliary view is a projection from the primary auxiliary view onto a plane perpendicular to the true length edges. In this view, the sides and bottom of the groove appear as edges, as if you are looking into the end of the groove.

**Are 2 parallel lines coplanar?**

Parallel lines are coplanar (they lie in the same plane) and never intersect. Just like with congruent segments, if there are two (or more) pairs of parallel lines, we use one arrow ( > ) for one pair and two (or more) arrows ( ≫ ) for the other pair….

#### Can auxiliary views be dimensioned?

There are an infinite number of possible auxiliary views of any given object. Why are auxiliary views used? When creating engineering drawings, it is often neccessary to show features in a view where they appear true size so that they can be dimensioned. In this case one or more auxiliary views typically are drawn.

#### How do you find true lengths?

To find the true length of a line you must take a view parallel to the line; in other words, if a line is a parallel to the folding line in one view, it is shown in true length in the adjacent view.

**What is a true shape?**

The true length of a line and the true shape of an object are their actual lengths and shapes. Two views are needed to find the true length of a line or shape to overcome errors that could be caused by the viewing angle. …

**What is apparent length?**

An apparent leg length can be measured from the umbilicus to the medial malleoli of the ankle (Fig. A “direct” measurement using a tape measure can be utilized to measure the “true” leg length from the anterior superior iliac spine (ASIS) to the medial malleolus.

## How do you correct leg length difference?

Stretching exercises to loosen and lengthen muscles are used to correct functional leg length discrepancy. They also help improve back pain and other symptoms. The main muscle to stretch is called the quadratus lumborum. This muscle connects the pelvis and backbone….

## What is a Scanogram?

scanogram. A radiographic technique for showing true dimensions by moving a narrow orthogonal beam of x-rays along the length of the structure being measured, e.g., the lower extremities….

**What is true length and apparent length of a line?**

A: True leg length is a measure from a point on the pelvis (ASIS) to the ankle and apparent leg length is a measure from the umbilicus to the ankle….

**What is apparent leg length discrepancy?**

Leg length discrepancy can be divided into 2 etiological groups: true LLD, defined as those who are associated with shortening of bony structures, and apparent LLD, defined as those who are the result of altered mechanics of the lower extremities.

### What is true angle and apparent angle?

TRUE LENGTH (T.L.) AND TRUE INCLINATION (T.I.) The position of T.V. is a function of the True Inclination with the V.P., i.e., Φ. • If the F.V. of the line is T.L., then it must appear at an angle of θ with the xy line. The very moment ones sees a shorter length in the F.V., the apparent angle shall be larger than θ.

### What is apparent length in engineering drawing?

♣ If a line AB is parallel to a reference plane, then the projection of the line AB obtained on that reference plane will have true length and true inclination. ♣ If a line AB is inclined to a reference plane, then the projection of the line AB obtained on that reference plane will have apparent length….

**What is apparent shape of section?**

Sectional view : The projection of the section along with the remaining portion of the object is called a Sectional View. Projection on the other plane is called apparent section. 2. True shape of the section : Projection of the section on a plane parallel to the section plane will show the true shape of the section….

**What is true angle?**

The true angle between two planes can be measured in a view where both planes appear as lines. To measure the true angle between two planes, a view must be constructed where both planes appear as lines. In that view, the line of intersection will appear as a point.

#### When a plane is parallel to VP and perpendicular to HP and PP always?

Whereas if a plane is parallel to h.p and perpendicular to v.p, then pp is always back view (BV) first….

#### When a point is above HP and behind VP The point is resting in which quadrant?

Explanation: The position of reference planes will be similar to quadrants in x, y plane co-ordinate system. As the 2nd quadrant lies above the x-axis and behind the y-axis here also the 2nd quadrant is above H.P, behind V.P.

**When the axis of solid is perpendicular to HP?**

Explanation: When the axis of solid is perpendicular to H.P it is indirectly saying that the base is parallel to the horizontal plane so the projection on to it gives true shape of the base and then we can project and find the other dimensions. 4.

**Which line type is thick and black *?**

Answer. Answer: Object lines and hidden lines….

## How many battens will be there for a drawing board?

Explanation: Generally drawing board has dimensions of 1000 x 1500, 700 x 1000, 500 x 700, 350 mm x 500 mm, and made of well-seasoned soft wood, so there would be no bending while life increases. And also if a size of drawing board increases widely then the board will be fabricated with another 1 or 2 battens.
