Question 26

The tool in the image is a dial caliper, which is used for precise measurements. An engineer’s scale is for scaling, a digital micrometer has a different design, and a scientific ruler is a basic ruler. So the correct option is B.

The icons represent geometric constraints (like perpendicular, parallel, etc.) used in CAD to define sketched geometry. Assembly is for putting parts together, numeric is about numbers, and design is a broader term. So the correct option is D.

To determine the method, additive builds up, subtractive removes, skeletal is a framework, and assembly is combining parts. If the model is created by adding material (or features), but more likely, if it's a solid model created by adding (like extrusions, etc.), but the options: additive is building up. However, sometimes subtractive is cutting, but the question's model (assuming typical solid modeling) – but the options: the correct method here is likely additive or subtractive. Wait, the options: A is Additive, B Skeletal, C Subtractive, D Assembly. If the model is created by adding features (like extruding a sketch), additive. But maybe the correct answer is A or C. Wait, maybe the model is created by additive (building up) or subtractive (cutting from a base). But the standard: additive manufacturing is building, but in CAD, solid modeling can use additive (extrude, revolve) or subtractive (cut). But the question: the correct option is A. Additive? Wait, no, maybe the answer is A. Additive or C. Subtractive. Wait, maybe the correct answer is A. Additive. But let's think again. The steps to create a solid model: additive is building by adding features, subtractive is removing. So if the model is made by adding (like extruding a rectangle to make a prism, then adding another), additive. So the correct option is A.

Answer:

B. Dial caliper
