Comprehensive Tutorial For AICADGIS

New Project

Creates a blank workspace. Clears the current canvas entirely.

Layer Panel Actions

Tools available directly on the Layer Panel in the left sidebar.

• Click the '+' icon to Add a New Layer.
• Click the Trash Can icon to Delete the selected layer(s).
• Double-click a layer name to Rename it.
• Click the Eye (👁️) icon to toggle visibility on/off.
• Click the Lock (🔒) icon to prevent selection or modification of objects on that layer.
• Click the Target (🎯) icon to instantly Fit View to all objects on that layer.

Point

Places a single 3D coordinate point.

Text (Single Line)

Places a standard single-line label. Opens the Precise Text Dialog to set text content, height, rotation, and XYZ insertion point.

Move, Copy, Rotate

Basic transformations.

• Select object(s) -> Select Tool -> Right-Click.
• Click a Base Point.
• Click a Destination Point (or type an angle for Rotate).

Floating Measure Window

Toggle the calculator icon (∑) to open a window that tracks cumulative distances, areas, and coordinates as you measure.

Object Properties Dialog

The primary inspector for a single selected entity. Select an object to view its exact makeup.

Measurement & Units

Define how coordinates, distances, and angles are displayed and calculated across the entire application.

• Length Unit: Choose between Metric (m, cm, mm) or Imperial (ft, in) units.
• Coordinate Format: Toggle between standard Cartesian (X,Y,Z) for CAD, or Geographic formats (Decimal Degrees, DMS) for GIS workflows.
• Angle Unit: Set default angular measurements to Degrees, Gradians, or Radians.
• Decimal Precisions: Independently adjust how many decimal places (0-8) are shown for lengths, coordinates, and angles in the properties panels and labels.

Snapping (OSNAP)

Top toolbar. Forces your mouse to lock onto exact geometry.

• Endpoint (□): Snaps to the ends of lines/arcs.
• Midpoint (△): Snaps to the exact center of a line segment.
• Center (○): Snaps to the origin of circles/arcs.
• Intersection (✕): Snaps to where two lines cross.
• Advanced (⊛): Turns all snaps on simultaneously.

How to Setup

Click the AI Chat tab in the left panel. Paste your API key (e.g., DeepSeek) into the chat box to authenticate.

Mobile Action Bar Overview

When using the application on a mobile device or narrow screen, a dedicated action bar appears at the bottom of the screen. This bar acts as a virtual keyboard/mouse, allowing you to trigger essential CAD commands without physical inputs.

Download OSM Data

Access the OSM Download dialog to fetch map data for your current area.

• Define a bounding box on the canvas or use the current view extent.
• Select the features to include (e.g., Buildings, Highways, Amenities, Water).
• Click download to instantly generate structured CAD geometry from the real-world data.

Create TIN (From Selection)

Generates a Triangulated Irregular Network (3D surface mesh) using the exact Z-coordinates of selected objects.

• Selection: Highlight the objects (Points, Lines, Polylines, etc.) containing elevation data before opening the tool.
• Min Z / Max Z: Automatically populates based on your selection. Manually adjust these to filter out erroneous outlier elevations.
• Min / Max Edge: Constrains triangle generation. 'Max Edge' prevents the tool from interpolating long, inaccurate triangles across the outside bounds of concave surveys. Set to 0 to disable.
• Include Types: Toggle exactly which entity types from your selection are used for the calculation (e.g., turn off 'Line' to only triangulate 'Point' data).
• Create: Generates the mesh as 3D Faces on a new TIN layer.

New Layout Manager

Create and manage multiple paper space layouts for your project.

• Access the Layout Manager via the bottom tabs or side panel.
• Click 'New Layout' to open the New Layout Dialog.
• Define your Sheet Size (A4, A3, A2, A1, A0) and Orientation (Portrait or Landscape).
• Set the global sheet margins for printing constraints.
