Brush, Lasso, or Auto: Which Selection Tool Is Right for You?
Discover how Feel Design’s Brush, Lasso, and Auto Selection tools help you edit like a pro. Learn which one suits your design task best for precision, speed, and creativity.
Introduction: Precision Is Power in AI Design
In AI-powered interior design, precision makes the difference between a good edit and a flawless one. Whether you’re restyling a wall, swapping a sofa fabric, or changing an entire floor, how you select your area of focus determines how clean and realistic your results look.
That’s where Feel Design AI Studio’s Selection Tools come in. Designed for accuracy and speed, these tools — Brush, Lasso, and Auto Selection — give creators the control they need to isolate, refine, and reimagine every element of their design.
Each tool serves a unique purpose. Understanding when to use which can turn your editing workflow from time-consuming to effortless.
1. Brush Selection: Paint Your Precision
The Brush Selection Tool is your go-to for manual, detailed editing. It works like a digital paintbrush, letting you “paint” the area you want to edit directly onto your image.
When to Use It
Adjusting or replacing small objects like chairs, lamps, or rugs.
Editing textures or fabrics (e.g., changing velvet to linen).
Refining edges around complex shapes for pixel-level accuracy.
Why It’s Powerful
Brush selection mimics the behavior of professional photo-editing software — but with Feel Design’s intuitive AI assist. As you paint over a region, the AI detects edges, preventing messy overlaps. You can control:
Brush Size – for broader or finer strokes.
Hardness & Opacity – for soft transitions or sharp boundaries.
Edge Sensitivity – for seamless object isolation.
It’s ideal for perfectionists and detail-oriented designers who want total control.
Pro Tip: Use smaller brush strokes around intricate decor and zoom in when refining details. This helps maintain natural lighting and material texture transitions.
2. Lasso Selection: Freedom to Trace and Shape
The Lasso Tool is perfect for designers who prefer freehand control. It allows you to outline irregular shapes manually — or click to create straight lines — offering a balance between precision and flexibility.
When to Use It
Outlining decor items with organic forms (like plants, sculptures, or curtains).
Selecting uneven edges or non-rectangular surfaces.
Creating multi-object selections in one move.
Modes You Can Use
Feel Design’s Lasso Tool comes with two modes:
Freehand Mode – Draw your outline freely using your cursor or pen. Great for natural shapes.
Polygonal Mode – Click to mark points that connect with straight lines, perfect for furniture or architectural features with defined edges.
You can also combine them, using Shift to add to your selection or Alt to subtract unwanted parts.
Why It’s Powerful
The Lasso Tool provides unmatched creative flexibility. It’s the ideal middle ground for designers who want manual control without pixel-by-pixel effort. Once selected, you can apply materials, colors, or lighting adjustments only to that area — keeping the rest of the scene intact.
Pro Tip: For geometric or structural elements like doors, frames, or tables, Polygonal mode ensures crisp, straight-edge selections every time.
3. Auto Selection: Let AI Do the Heavy Lifting
If you want speed and efficiency, the Auto Selection Tool is your best friend. Powered by AI edge detection, this mode identifies regions based on color similarity, contrast, and shape boundaries — automatically selecting entire surfaces with one click.
When to Use It
Selecting large, uniform areas such as walls, floors, or ceilings.
Replacing materials (e.g., from tile to marble, or matte paint to gloss).
Performing quick edits across multiple similar surfaces.
How It Works
Auto Selection analyzes your image to locate consistent patterns or hues. It’s smart enough to:
Detect edges and color transitions.
Avoid overlapping with unrelated areas.
Suggest adjustable selections you can fine-tune manually.
Once selected, you can immediately apply a new material, lighting tone, or design preset — and watch your edit appear in seconds.
Why It’s Powerful
Auto Selection saves you significant time without sacrificing quality. It’s perfect for high-volume design tasks or when you need a fast preview before deeper customization.
Pro Tip: Use Auto Selection first to outline large areas, then refine with the Brush Tool for edges and detail work.
🧩 Choosing the Right Tool: A Designer’s Guide
Each Selection Tool has its place in the creative process. Here’s how to decide quickly:
Tool | Best For | Precision | Speed |
|---|---|---|---|
Brush | Fine details, textures, small areas | 🔹🔹🔹🔹🔹 | 🔹🔹 |
Lasso | Irregular or complex shapes | 🔹🔹🔹🔹 | 🔹🔹🔹 |
Auto | Large surfaces and quick changes | 🔹🔹🔹 | 🔹🔹🔹🔹🔹 |
The beauty of Feel Design AI Studio lies in combining these tools fluidly. You might start with Auto Selection to define a wall, then switch to Brush to refine the corners, and finally use Lasso to exclude overlapping objects.
This hybrid workflow mirrors how professionals think — fast, flexible, and precise.

The Selection Tool Suite in Feel Design AI Studio isn’t just about marking areas — it’s about unlocking creative precision.
Whether you paint with Brush, trace with Lasso, or click with Auto, each method empowers you to bring ideas to life seamlessly.
