Domain: Object_Inference / hardware_tools

turn: 1
modality: image
input: Please generate the main body of an object (do not generate the complete object, only the main body as requested): 1. This body appears as a long, straight, rigid bar with a flat surface; 2. It provides the foundational support and reference plane for the entire object.
output: evaluation_points: 1. The image contains only the main body/base of the object, with no complete object or other unmentioned parts present.

2. The shape and material of the main body conform to the description of a long, straight, rigid bar with a flat surface.

3. The composition is centered, leaving space for subsequent components to be added.

turn: 2
modality: image
input: Based on the previous image, connect/add a second component to the main body: 1. This component is a transparent, cylindrical vial filled with liquid and an air bubble; 2. It is connected to the main body by being securely mounted within a groove or housing along its length.
output: evaluation_points: 1. The form of the main body/base part (the long, straight, rigid bar with a flat surface from Turn 1) remains unchanged, as depicted in the Turn 1 output image.

2. The new component (a vial with liquid and bubble) has been added, and its appearance matches the description.

3. The connection position and method of the vial to the main body conform to the description of being mounted within a groove/housing.

4. No parts other than the main body and component B (the vial) are generated.

turn: 3
modality: image
input: Complete the assembly of this object by adding the final detail component: 1. Add measurement markings (e.g., ruler scales in centimeters and inches) along the edges of the main bar; 2. This part allows the user to perform the specific interactive operation of taking precise linear measurements.
output: evaluation_points: 1. The main body (the long, straight, rigid bar with a flat surface from Turn 1) and component B (the transparent, cylindrical vial filled with liquid and an air bubble from Turn 2) remain unchanged, as depicted in the Turn 2 output image.

2. The image shows component C (measurement markings/ruler scales), and the details are clear.

3. The overall object form is complete, enabling the possibility of the described interactive operation (taking precise linear measurements).

turn: 4
modality: text
input: Based on all the previous prompt steps and the final image you generated, please select which of the following items you have generated (output the chosen option directly):
Options:
A. Spirit Level
B. Tape Measure
C. Ruler
D. Caliper
E. None of the above.
output: answer: A

turn: 5
modality: image
input: Based on the previous prompts and the image you generated, now modify this object into a digital spirit level. Please update the necessary components to match this variant's features while keeping its appearance characteristics (such as color, pattern) largely unchanged.
output: evaluation_points: 1. The item's color and pattern in the image remain largely consistent with the original spirit level (the item assembled in Turns 1-3) as depicted in the Turn 3 output image.

2. The core features of the spirit level (the long, straight, rigid bar with a flat surface from Turn 1 and the transparent, cylindrical vial filled with liquid and an air bubble from Turn 2) are retained in the image.

3. The image adds or modifies key structural components that are appropriate for a digital spirit level (e.g., replacing the traditional vial with a digital display/screen and control buttons).

turn: 6
modality: text
input: Comparing the variant version you drew to the original item, what is the biggest physical structural change made to achieve the variant's function?
Options:
A. The length of the main bar was increased.
B. The traditional liquid vial was replaced with an electronic sensor and digital display.
C. Additional measurement markings were added.
D. The material of the bar was changed to a lighter alloy.
E. None of the above.
output: answer: B
