Write Mode
Write mode is the most feature-complete mode. In addition to all the capabilities of review mode, it supports directly creating, editing, and deleting entities on the DWG/DXF — enabling the web product to handle real drafting work, not just read-only preview.
Write mode is used by default when opening a file, unless read-only or review mode is explicitly specified.
Desktop
Overall Layout
Top Ribbon
The Ribbon fully displays all AutoCAD-style tabs:
| Tab | Commands |
|---|---|
| File | Open, Export DXF, Export PNG, Export Self-contained HTML |
| Draw | Line, Circle, Arc, Rect, Polyline, Hatch, Text, MText, Block Insert, etc. |
| Modify | Move, Copy, Offset, Trim, Extend, Rotate, Scale, Mirror, Array, etc. |
| Layers | Layer management (on/off, freeze/thaw, lock, isolate, new, delete) |
| Properties | Color, linetype, lineweight, layer selector |
| Measure | All measurement commands |
| Markup | All markup commands |
Command Line
A command line window at the bottom of the canvas allows typing command names directly (e.g., L + Enter to draw a line, C + Enter to draw a circle). Supports:
- Displaying command prompts and history
- Entering numeric values and coordinates
- Using up/down arrows to browse command history
Right-Side Toolbar
In addition to the review mode tools, there is a Select / Edit tool group:
- Select
- Pan
- Zoom to Extents
- Window Zoom
- Layer Management
- Measure tool group
- Markup tool group
- Reading Mode
- Toggle Light/Dark Background
Docked Panels
| Panel | Description |
|---|---|
| Layers | Full layer management |
| Properties | Selected entity properties (type, coordinates, layer, color, linetype, lineweight, etc.), editable |
| Measurements | Measurement result management |
| Review (Markup) | Markup management |
| Statistics | Block usage statistics |
| Missing Resources | Font / external reference alerts |
Status Bar
A full CAD status bar, from left to right:
| Area | Description |
|---|---|
| Layout tabs | Model space / layout switch |
| Command prompt | Prompt text for the currently active command (e.g., "Specify start point:") |
| Coordinates | Real-time cursor coordinates |
| OSNAP | Object snap toggle and configuration |
| ORTHO | Orthogonal mode |
| POLAR | Polar tracking |
| Object Snap Tracking (OTRACK) | |
| Lineweight display | |
| Dynamic Input | Floating input box toggle |
| Isometric | |
| Theme | |
| Fullscreen |
Tablet (Pad)
The tablet layout is between desktop and mobile, but write mode retains the full components needed for editing:
- Ribbon retains full tabs, but command buttons collapse to icons
- Right-side toolbar is retained
- Command line is collapsed to a small bar by default; click to expand
- Docked panels can be expanded as side drawers
- Status bar shows core buttons in a simplified form
Mobile
In write mode on mobile, the command line and full draw/modify capabilities are implemented via a Mobile Command Overlay, replacing the bottom tab bar.
Command Overlay
When executing a draw or modify command, a command operation bar appears at the bottom of the screen, containing:
- Current command prompt
- ✓ Confirm / ✗ Cancel buttons
- Dynamic Input (DYN) popup panel
Input Methods
Mobile drawing uses the following input methods:
- Tap point input: tap the screen (<0.5s) to create a point
- Drag point input: long press the screen (>0.5s), enter drag-select mode and release
- Simulated Mouse: enabled by default; long press and a crosshair appears above the finger; the actual input position is based on the crosshair
- Magnifier: toggle in settings; a circular magnifier HUD enlarges the finger area
Auto Return
During command execution, the status bar is temporarily hidden (the command overlay takes over input). After the command ends, the status bar is restored.
