AI Prompt, Generation and Adjustment Process

Prompt:

Help me make a steering wheel and seats on this car, with more details

Feedback:

Need to change the steering wheel radius to 4.5cm, the seat style is a bit strange, let's modify it again
AI Prompt 1 AI Generation 1

Prompt:

Why is the chair clipping through? Move both the steering wheel and chair backward by 4cm; the steering wheel position is wrong, the rod and disk are separated; this steering wheel doesn't look right
AI Prompt 2 AI Generation 2 AI Adjustment 2

Prompt:

Move the seat further away from the steering wheel
AI Prompt 3 AI Generation 3 AI Adjustment 3

Prompt:

Reduce the seat armrest thickness by half
AI Prompt 4 AI Final Result

By writing prompts to AUTODESK ASSISTANT, we helped create two parts: a steering wheel and a car seat. Specific positions and dimensions need to be specified for easy modification later. I shortened the seat length and reduced the armrest thickness, finally completing the part creation.

Step 3:

Create a lid to prevent items from falling out due to bumps. The connection method is magnetic attachment.

Click the "Create Sketch" icon again, select the upper plane of the box, draw the same area as the box, and click "Finish Sketch" when done.
