⭐️⭐️⭐️⭐️⭐️

This app is seriously awesome! I’ve been using it to create 3D deck designs, and it makes it so much easier to visualize what a finished deck will actually look like. The ability to draw and customize different deck layouts is really helpful, especially when planning a project and trying different ideas.

Definitely a great tool for anyone who designs, builds, or is even just thinking about building a deck. Excited to see how this app continues to improve!

## Version history (last 5 releases)

### 1.6.2 — 2026-09-30

More flexibility for decks that turn corners.

• Rotate beams and joists independently in sections of L- and U-shaped decks, with matching 3D decking, transition boards, and picture frames.
• Add a composite drink rail in any decking color, choose flush or protruding posts, and control drink rails on landings separately.
• Choose whether a cantilever adjustment moves just the selected beam or all automatic beams.
• Keep 2D stair measurements clearer: Dimensions now hides stair labels too, and tread depth and riser height are removed from the plan.
• Try Build a Turn Deck in the redesigned Learn area. Trace the guide in one drawing step, follow precise section and button highlights, and resume your practice or start again.

### 1.6.1 — 2026-09-26

More control over your deck details.

• Enter exact wall lengths from the 2D plan or wall settings.
• Keep your plan clearer with deck dimensions shown by default and other measurements shown when selected.
• Show or hide a selected wall's dimension with the eye button. Wall and stair controls disappear when you deselect them.
• Edit railing sections and posts on L-shaped, U-turn, and straight-stair landings.
• Find the new Generate Blueprints button more easily, then add text, tags, and lines directly on the drawing sheets.
• Suggest a feature or leave a review from Preferences. Review prompts appear after you've had time to use the app.

### 1.6 — 2026-09-25

More room to design, more control over the details.

• Enjoy a refreshed iPhone workspace with a larger drawing canvas, clearer tools, quick layers, and easy view switching.
• Tap 2D dimensions to enter exact sizes. Add, move, and delete outline nodes, with 3-inch snapping while dragging.
• Draw custom landings and concrete pads with the same flexible outline tools as decks.
• Connect stairs to landings with automatic landing-height adjustment, and add stair support posts.
• Use L-shaped and U-turn stairs in Basic mode.
• Add your own lines, descriptions, and tags in Pro Blueprint.
• Follow clearer, step-by-step Learn lessons with brighter highlights and new node-editing guidance.
• Start projects from a refreshed home screen.
• Includes fixes for stair placement, width editing, railing visibility, saving, and narrow stair controls.

### 1.5 — 2026-09-19

More natural 3D views, clearer connections, and new ways to learn.

• Explore richer surface finishes and five new colors with subtle variation.
• Switch between fitted camera views. Flat views stay square while you pan, and Perspective uses a gentler lens.
• Choose which deck, stair, landing, roof, and height dimensions appear in 3D.
• Review improved railing connections across the model, 2D plans, blueprints, and material lists.
• Choose flat-board picture-frame and divider supports, with matching framing and material quantities.
• Select blocking directly in the 3D framing view.

Clearer stairs, framing, materials and 3D measurements.

• Show bold deck and landing dimensions in 3D, with preset Perspective, Top, Front, Right, Back and Left views.
• Read deck height directly from the elevation you entered.
• Edit selected stairs from a settings screen with a live side-elevation drawing.
• Improve L-shaped and U-turn landing framing, wall-supported landings, and stair railing spacing.
• Place stairs using a gentle center snap and temporary midpoint guides.
• Add optional joist blocking and picture-frame and divider-board support, including on stair landings.
• Position dividers with 25%, 50% and 100% presets plus fine adjustments. At 100%, the divider reaches the deck edge.
