In this guide, we’ll show you how to use Plan AI with the ArchDiffusion v4.1 engine, an ideal choice for all types of 2D floorplans. You’ll get a quick tour of the updated interface, discover the latest upgrades, and explore sample parameters you can start using right away. Let’s dive in.
Interface Walkthrough
You’ll find the v4.1 engine listed alongside other engines in the top-left corner of the interface. This is where you select the version you want to work with.

Next up is the Expert section. Here, you can define your project type, such as Interior, Exterior, or Plan. Choosing the correct project type helps the engine better understand your goals and deliver more accurate, relevant results.

Below that is the Camera section, which includes two settings: Rotate and View. These options let you control the angle and perspective of your image. You can stick with the original view or switch to alternatives—like a top view—depending on how you want to present your masterplan.

The Lighting section comes next. This setting allows you to define the overall mood of your render based on the time of day. At the moment, Daylight is the only available option.

After lighting, move on to Render Style. This determines the overall look and feel of your output. While Realistic is the most commonly used style, you can also experiment with options like CGI or Sketch to suit different presentation needs.

The second-to-last section is Geometry, which plays a major role in shaping your final result:
- Choose Precise to maintain accurate geometry.
- Select Creative for a more flexible and expressive interpretation.

At the bottom of the interface, you’ll find Reference Images. This feature helps guide the AI toward a specific look or style. You can upload up to four reference images to improve consistency and better align the output with your vision.

To finish setting up, head to the prompt box and select a Scenario. Choose Render for a more controlled and accurate result, or Edit if you’d like more creative freedom.

Once everything is ready, simply click Render and wait a few seconds to see your masterplan come to life.
