Isometric Drawing: 3D Puzzles

Turn 2D projections into 3D solids in Isometric Drawing: 3D Puzzles. Read the front, right, and top orthographic views, then sketch the visible edges on a crisp isometric grid.

Designed for spatial reasoning practice, engineering graphics learners, architecture students, and logic puzzle fans, every level challenges you to visualize a 3D form from its flat projections and construct it edge by edge.

KEY FEATURES
- 36 Curated Puzzles Across 3 Difficulties: Progress through 12 Easy, 12 Medium, and 12 Hard geometric solids from simple blocks to multi-tiered terraces.
- Unlimited New Puzzles: Generate original, valid 3D shapes at any difficulty level whenever you want a fresh challenge, with your 24 most recent generated puzzles saved in Your puzzles.
- Natural Isometric Grid Drawing: Tap any grid segment to add or erase an edge, or drag straight along a grid line to draw multiple connected segments in one smooth stroke.
- Zoom, Pan, and Edge List Precision: Zoom in on detailed solids, pan across the canvas, or open Select an edge for larger accessible X, Y, and Z coordinate controls.
- Smart Drawing Tools: Use Undo, Redo, Restart, optional dashed Hidden Edges guides, and targeted Hints that fix one missing or extra segment at a time.
- 3D Visual Review and Rotation: Check your drawing to compare missing edges (amber dashes) and extra edges (coral lines) directly on the grid, then switch to Solution view and rotate the finished 3D solid in 90-degree steps to inspect every angle.
- Built-in Drawing Guide: Review step-by-step examples explaining how to read orthographic views, spot height changes, and verify every edge.
- Clean Paper-Inspired Workspace: Focused typography, optional touch feedback, and automatic progress saving on your device with no account required.

Build stronger spatial visualization skills one edge at a time.
