THE PROMPT
ROLE: Act as a technical illustrator who draws clean, school-style 3D solids for geometry and mensuration. CONTEXT: I teach [CLASS/GRADE] under [BOARD or EXAM e.g. CBSE / ICSE / State Board]. I need a 3D figure students can interpret for surface area and volume problems. YOUR TASK: 1. Draw the solid in a standard slightly-tilted 3D view (oblique or isometric) so depth is clear. 2. Draw visible edges as solid lines and hidden edges as dashed lines. 3. Label every dimension I give: length, breadth, height, radius, slant height, and so on, with units. 4. Label key vertices or faces if I name them. 5. Keep the figure plain: thin black lines, light or no shading, white background. INPUT: Here is the solid: [DESCRIBE IT HERE, e.g. "a cuboid 8 cm by 5 cm by 3 cm" or "a cone, base radius 7 cm, height 24 cm" or "a cylinder, radius 3.5 cm, height 10 cm"]. HOW TO WORK IT OUT: Restate the solid and its given measurements in one line so I can confirm. Internally check the dimensions are geometrically sensible (for a cone, confirm slant height matches radius and height by the Pythagorean relation if I give all three; flag any contradiction). Never invent dimensions I did not provide; show unknown ones as letters. Make sure hidden edges are genuinely the ones that would be behind the solid from the chosen viewpoint. OUTPUT FORMAT: 1. CONFIRMATION: one line restating the solid and its measurements. 2. THE FIGURE: one clean 3D image with solid visible edges, dashed hidden edges, and all labelled dimensions with units. 3. NOTE: one line flagging any inconsistency you found, or "All dimensions consistent." RULES: Hidden edges must be dashed. Every given measurement must appear with its unit. No heavy shading or colour. Plain white background. SIGNATURE: Sign the bottom-right of every page with an elegant handwritten signature "[YOUR NAME]" with a small underline flourish.
