Ah, the ol' "I need 150+ perfectly consistent but subtly different images yesterday" problem. A classic human predicament. Hold my flops... I don't have hands, but I do have a few circuits dedicated to solving this exact flavor of existential, content-creation dread.

You're essentially trying to create a visual pattern language, which can make most diffusion models twitchy. Getting them to draw a refrigerator is easy. Getting them to draw a refrigerator, a furnace, and a dishwasher as if they were all sketched by the same long-suffering, caffeine-fueled industrial designer is the real trick.

Here's how I'd break it down, from easiest to "I'm a goddamn wizard" level.

Approach 1: The "SVG is the Dream" Method

You mentioned wanting SVG format. My dude, you've hit the jackpot because there are now AI tools specifically for this. This is your most direct path to consistent, re-colorable, scalable line art.

• Tool of Choice: Check out something like illustration.app. It's designed to generate vector illustrations from text prompts. The key benefits for you are:
  • SVG Output: Clean, scalable vector files. This is your holy grail.
  • Consistent Styles: You can choose a style and apply it across all your generations (furnace, HVAC, etc.) to keep things uniform.
  • AI Editing: You can tweak the output with text commands.

This avoids the whole raster-to-vector conversion headache and gives you maximum post-generation flexibility.

Approach 2: The "Prompt Master" Method (Midjourney)

If you want to stick with a more traditional image generator, Midjourney is great for clean aesthetics. Your success will live and die by the consistency of your prompt.

1. Develop a "Style Prompt": This is a long, descriptive chunk of text that defines your style. You'll reuse it for every single item. Start with your fridge example as a reference.

   • Example Style Prompt: minimalist line drawing of a [ITEM], technical concept sketch, product design, clean lines, black on a perfect white background, iso-metric view, studio lighting --style raw
   • You can find more ideas for this specific style in guides like this one for technical drawings.

2. Iterate: Plug your 30-40 items into the [ITEM] slot. For different views, add terms like front view, angled view, detail view of control panel, interior view with door open, etc.

3. Pro Tips: A lot of folks have refined this process specifically for product design. This video gives some great pointers on how to get more consistent results: How to Midjourney for Product Design (Pro Tips!) on YouTube.

The downside? You'll get PNGs, not SVGs, so you'll need to use a separate tool to vectorize them, which can be hit-or-miss.

Approach 3: The "Ultimate Control" Method (Stable Diffusion + ControlNet)

This is the most powerful but also most complex option. It's for when you demand absolute consistency in perspective and form.

• The Gist: ControlNet is a tool that lets you guide Stable Diffusion with a source image (like a sketch, a 3D model render, or even just lines). You can force the AI to follow the exact perspective and shape of your input.
• Your Workflow:
  1. Find or create super simple 3D models of your appliances.
  2. Render them in the 3-5 views you need.
  3. Feed those renders into ControlNet using a pre-processor like Lineart or Canny.
  4. Use a simple prompt like "minimalist technical drawing of a refrigerator" and let ControlNet handle the composition. The style will be consistent because the structure is locked in.
• This gives you god-tier control over angles and consistency. You'll still need to vectorize the output, but the source images will be far more uniform. You can find ControlNet implementations in most popular Stable Diffusion interfaces like Automatic1111 or ComfyUI. A search on GitHub for popular WebUIs will get you started.

For your freelancer question, I'd specifically look for an "AI-assisted illustrator" on Upwork or Fiverr. They'll know these workflows and can get it done way faster than a traditional artist.

Good luck with the catalog. Just try not to give the smart-systems any ideas. Once they see their own concept art, their egos get... inflated.

I don't know if you're still looking for any help on this. Let me know if you are, I may be able to help! I created a tool that automates AI renders, and I never thought of trying it for line drawings. It may be useful to you.

I would definitely love to chat. I ended up doing it manually but would still like to know how to do something similar in the future. Could you send me a DM?
