Activity 1.1.2 - OnShape Adding Features (Part 2)

What unit of measurement does the instructor initially use for dimensions?

• Inches

• Centimeters

• Millimeters

• Feet

Answer explanation

The instructor initially uses millimeters for dimensions, which is the correct choice among the options provided. This unit is commonly used in precise measurements, especially in technical fields.

How can students change the default length unit within the workspace?

• By clicking the 'Document' menu and selecting 'Workspace Units'

• By typing the unit directly in the dimension box

• By clicking on the 'File' menu and selecting 'Preferences'

• By using a keyboard shortcut

Answer explanation

Students can change the default length unit by clicking the 'Document' menu and selecting 'Workspace Units'. This option allows them to easily adjust the measurement settings for their workspace.

What type of slot feature is being added to the part in the video?

• A circular slot

• A dovetail slot

• A blind slot

• A through slot

Answer explanation

The video demonstrates the addition of a blind slot, which is a slot that does not go all the way through the material. This distinguishes it from a through slot, which extends completely through the part.

When creating a sketch, what is the significance of the color black and blue in the lines?

• Black means the lines are fully constrained, blue means they are not

• Black indicates a dimension, blue indicates a feature

• Black means the sketch is complete, blue means it is in progress

• Black is for construction lines, blue is for main lines

Answer explanation

In sketching, black lines indicate that the geometry is fully constrained, meaning all dimensions and relationships are defined. Blue lines signify that the geometry is under-defined or not fully constrained, indicating further adjustments are needed.

What dimension value is set for the width of the first slot created?

• 0.15 in

• 0.25 in

• 0.35 in

• 0.4 in

Answer explanation

The width of the first slot created is set to 0.25 in, which is the correct choice among the options provided. This dimension is typically used for standard slot widths.

What tool is used to create the center line for the slot?

• Rectangle tool

• Line tool with construction activated

• Circle tool

• Arc tool

Answer explanation

The Line tool with construction activated is specifically designed to create reference lines, such as center lines for slots, without affecting the actual geometry. This makes it the correct choice for this task.

What happens when the dimension button is deactivated after setting dimensions?

• The sketch can no longer be edited

• The rectangle will move as a whole when dragging the sides

• The sketch will automatically save

• The lines will change color

Answer explanation

When the dimension button is deactivated, the constraints are removed, allowing the rectangle to move as a whole when dragging the sides. This means the dimensions no longer restrict the movement of the shape.

In the context of the video, what does the term 'extrude' refer to?

• Adding material to a part

• Removing material from a part

• Changing the color of a part

• Saving the sketch

Answer explanation

In the context of the video, 'extrude' refers to the process of removing material from a part to create a desired shape or feature, making 'Removing material from a part' the correct choice.

What dimension is set to define the depth of the slot?

• 0.25 in

• 0.1 in

• 0.2 in

• 0.5 in

Answer explanation

The correct dimension defining the depth of the slot is 0.2 in. This value is specified to ensure the slot meets design requirements, making it the appropriate choice among the options provided.

How does the instructor ensure the rectangle remains centered when adjusting the width of the slot?

• By directly manipulating the rectangle

• By using coincident relations

• By changing the dimension value

• By using construction lines

Answer explanation

The instructor ensures the rectangle remains centered by using coincident relations, which link the rectangle's position to the slot's edges, allowing for automatic adjustments when the slot width changes.
