Intro to Parts

### 1. What are Solidworks Planes used for?

• A.

To define orientation of 3D workspace

• B.

To provide a 2D surface to create sketches on.

• C.

To provide design templates for aircraft

• D.

Both A and B

D. Both A and B
Explanation
Solidworks Planes are used for both defining the orientation of the 3D workspace and providing a 2D surface to create sketches on. These planes help in establishing the reference points and directions for designing and creating 3D models in Solidworks. By using these planes, users can easily create sketches and define the position and orientation of their designs in the 3D space. Therefore, the correct answer is "Both A and B".

### 2. To begin a Smart Dimension

• A.

Select Smart Dimension on the InContext toolbar

• B.

Select Smart Dimension on the Sketch Tools toolbar

• C.

Use mouse gestures and move up

• D.

All of the above

D. All of the above
Explanation
The correct answer is "All of the above" because all three options listed (selecting Smart Dimension on the InContext toolbar, selecting Smart Dimension on the Sketch Tools toolbar, and using mouse gestures and moving up) are valid ways to begin a Smart Dimension in the given context.

### 3. What gives a part depth?

• A.

A Feature

• B.

A Sketch

• C.

A Plane

• D.

An Assembly

A. A Feature
Explanation
A feature gives a part depth because it is a characteristic or attribute that is added to a part in a CAD (Computer-Aided Design) software. Features can include extrusions, cuts, holes, fillets, and other modifications that add or remove material from the part. These features create different levels or depths within the part, giving it a three-dimensional shape and structure.

### 4. When a sketch turns blue, what does this mean?

• A.

It is over-defined

• B.

It is under-defined

• C.

It is fully defined

• D.

You have exited the sketch

B. It is under-defined
Explanation
When a sketch turns blue, it means that it is under-defined. In computer-aided design (CAD) software, sketches are typically represented by lines and shapes. When a sketch is under-defined, it means that there are not enough constraints or dimensions applied to fully define the sketch. This can lead to ambiguity in the design and may result in unexpected changes when modifying the sketch.

### 5. When a sketch turns black, what does this mean?

• A.

It is over-defined

• B.

It is under-defined

• C.

It is fully defined

• D.

You have exited the sketch

C. It is fully defined
Explanation
When a sketch turns black, it means that it is fully defined. In computer-aided design (CAD) software, sketches are typically represented by different colors to indicate their status. Black is used to indicate that the sketch is fully defined, meaning that all the required dimensions, constraints, and relationships have been specified, and there are no degrees of freedom left for further modification. This ensures that the sketch is stable and can be used as a basis for creating 3D models or generating manufacturing instructions.

### 6. Create the following part with Plain Carbon Steel using an inch unit template.  The part your initials - SWFUND1DEI3.1.Q6. What is the mass of the part?

• A.

1.56 pounds

• B.

1.41 pounds

• C.

2.01 pounds

• D.

1.04 pounds

B. 1.41 pounds
Explanation
The mass of the part is 1.41 pounds. This can be determined by using the given information that the part is made of Plain Carbon Steel and using an inch unit template. The specific density of Plain Carbon Steel can be used to calculate the mass of the part.

Rate this question:

• 7.

### 7. Create the following part out of Brass using an inch part template.  The part should be saved as your initials-SWFUND1DEI3.1.Q7. What is the mass of the part?

• A.

1.56 pounds

• B.

2.10 pounds

• C.

1.84 pounds

• D.

1.65 pounds

C. 1.84 pounds
Explanation
The given question asks to create a specific part out of Brass using an inch part template. After creating the part, it should be saved with a specific name. The question then asks for the mass of the part. The correct answer is 1.84 pounds, which implies that the part created out of Brass using the inch part template has a mass of 1.84 pounds.

• 8.

### 8. Change the 3" dimension in the part from question 7 to 4." What is the new mass of the part?

• A.

1.84 pounds

• B.

3.28 pounds

• C.

2.75 pounds

• D.

5.16 pounds

B. 3.28 pounds
• 9.

### 9. Create the following part out of ABS PC using an inch part template and save it as your initials-SWFUND10EI3.1.Q9

• A.

1.84 pounds

• B.

3.28 pounds

• C.

2.32 pounds

• D.

5.16 pounds

C. 2.32 pounds
Explanation
The weight of the part created out of ABS PC using an inch part template and saved as "SWFUND10EI3.1.Q9" is 2.32 pounds.

### 10. Create the following part out of Nickel using an inch part template and save is as your initials-SWFUND1DEI3.1.Q10. What is the mass of the part?

• A.

1.54 pounds

• B.

1.28 pounds

• C.

2.32 pounds

• D.

4.15 pounds
