Here is the full prompt for that part: >The main cylinder axis is vertical along Z and centered at the origin. >Create a central barrel with diameter 36 mm and height 70 mm, bottom at Z = 0. >Around the barrel, add 12 horizontal circular cooling fins. Each fin is 2 mm thick in Z, has outside diameter 62 mm, and is spaced every 5 mm from Z = 10 mm to Z = 65 mm. >Add a thicker base flange at the bottom, outside diameter 70 mm and thickness 8 mm, with six vertical mounting holes of diameter 5 mm on a 56 mm bolt circle. >Add a top cap cylinder, diameter 44 mm and height 8 mm, from Z = 70 mm to Z = 78 mm. >Add an angled spark-plug boss protruding from the side of the top cap. The boss is a cylinder of diameter 12 mm and length 24 mm, angled upward at 35 degrees from horizontal, with its axis pointing outward in the positive X direction. >Add a 5 mm diameter hole through the boss along its own axis. >Add small 1 mm fillets to the outer fin edges and base flange edges. And the description still falls short, such as no room between the flange and fins to install nuts. What a nightmare to describe all this in text! when the language of drafting is able to describe it perfectly, wordlessly and unambiguous, in a single drawing sheet. Yes, there are a few thing to learn beyond "draw a picture", but it's not a lot. You can claim it's for "people who don't know CAD", but I have my doubts that those same people without those skills would be able to describe what they want in text.
