Mastering Selection Tools in Feel Design AI Studio: Brush, Lasso & Auto

When it comes to refining your designs in Feel Design’s AI Studio, one tool stands above the rest for precision: the Selection Tool. Whether you’re swapping out a chair’s texture, adjusting lighting, or recoloring an accent wall, being able to isolate just the right part of your space is key. To give users maximum control, AI Studio offers three powerful selection modes—brush selection, lasso selection, and auto selection—each suited to different types of edits.

Brush Selection: Paint Your Way to Precision

Brush selection gives you intuitive, hands‑on control over what you select. Much like Photoshop’s Quick Selection Tool, it “uses a brush to paint out selected regions,” and senses edges to create knowledgeable selections

. You can adjust the brush’s hardness, size, and even its shape to tailor your selection

. This flexibility makes brush selection ideal for detailed work—think replacing the upholstery on a sofa or changing the pattern of a rug.

Video Demo: Watch our quick tutorial on using brush selection to isolate and re-texture furniture. See how adjusting brush size lets you refine the edges and achieve seamless results.

Lasso Selection: Freehand & Polygonal Control

Need to outline something irregular like a decorative vase or a winding staircase? The lasso selection mode is your go‑to. In traditional design software, “the lasso tool requires you to trace your selection with your mouse,” making it perfect for organic shapes

. If you need more stability, switch to the polygonal mode, which lets you click vertices to create straight segments around your object

. Use SHIFT to add smaller selections for finer detail

Video Demo: Our lasso selection tutorial walks you through drawing a freehand outline around a decor item, then adjusting its material without affecting the rest of the scene.

Auto Selection: Let AI Find the Edges

For rapid selections, auto selection leverages AI to detect boundaries and similar colors—akin to the Magic Wand or Magnetic Lasso in Photoshop. These tools “automatically sense edges and lead the selection around them”, and can quickly select pixels of similar color for intuitive regions.

. This makes auto selection perfect for isolating large surfaces like walls, floors, or sky panels with a single click.

Video Demo: Check out our auto-selection video to see how AI Studio detects and selects an entire wall. Learn how to swap out materials instantly and fine‑tune the selection if needed.

Conclusion

The Selection Tool’s versatility empowers you to make precise, creative edits—no matter the shape or complexity of your design. By mastering brush, lasso, and auto modes, you can isolate any object or surface and effortlessly apply new materials, textures, or colors.

F.A.Q.

What is the Selection Tool in Feel Design AI Studio?

The Selection Tool in Feel Design AI Studio allows users to isolate specific parts of their design for precise editing. It gives you control over which areas to modify, whether you want to change a texture, adjust lighting, or recolor an object. The tool includes three modes—brush, lasso, and auto selection—each suited for different types of edits.

What is Brush Selection and how does it work?

Brush Selection lets you manually 'paint' the area you want to edit, giving you full creative control. You can adjust the brush size, hardness, and shape to refine your selection edges. This mode is perfect for detailed adjustments like re-texturing furniture, changing fabric patterns, or modifying small decor items.

When should I use Lasso Selection?

Use Lasso Selection when working with irregular or organic shapes such as vases, staircases, or plants. You can draw a freehand outline or use the polygonal mode for straight, angular edges. The Lasso Tool allows you to precisely trace around objects and even combine multiple selections for advanced control.

How does Auto Selection simplify editing?

Auto Selection uses AI to detect edges and regions of similar color, letting you select areas like walls, floors, or ceilings instantly. It’s ideal for large, uniform surfaces and speeds up the editing process. You can also refine or expand the AI’s selection to match your exact needs.

Can I combine different selection modes?

Yes. You can start with one selection mode and refine it using another for more precision. For example, begin with Auto Selection to capture a wall, then switch to Brush or Lasso mode to clean up edges or include intricate details.

Why is the Selection Tool important for design editing?

The Selection Tool gives designers precise control over what gets edited, allowing targeted changes without affecting the entire image. It’s essential for realistic results, efficient workflows, and professional-grade visual refinements in AI-generated interior designs.
