nanoCAD is available in both free and paid versions. The free version, nanoCAD Free, offers basic functionalities, while the paid versions provide advanced tools like 3D modeling, sheet sets, and custom command creation. This tutorial focuses on the foundational tools available in the free version, which are more than sufficient for beginners.
2. Understanding the User Interface
When you first open nanoCAD, you’ll see a workspace with several key areas:
- Menu Bar: Located at the top, it contains drop-down menus like File, Edit, and View, providing access to various commands.
- Toolbars: These are sets of icons representing frequently used commands, such as drawing tools (line, circle, rectangle) and editing tools (move, copy, rotate).
- Command Line: Positioned at the bottom, this is where you can type commands manually and see prompts or messages from the software.
- Drawing Area: The large central space where you create and edit your designs.
- Status Bar: At the very bottom, it displays information like coordinates and allows you to toggle settings like snap, grid, and ortho.
Getting Started
For beginners, it’s important to familiarize yourself with these areas. You can customize the toolbars and workspace by right-clicking the toolbar area and selecting which toolbars to display. Spend some time exploring the interface to feel comfortable navigating it.
3. Basic Drawing Tools
nanoCAD provides a variety of tools to create basic shapes and objects. Let’s explore some of the most commonly used drawing tools:
a. Line
The Line tool is fundamental for creating straight lines.
- How to Use: Select the Line tool from the toolbar or type LINE in the command line.
- Click to specify the starting point.
- Move the cursor and click again to specify the endpoint.
- Press Enter to finish.
b. Circle
The Circle tool allows you to create circles by specifying a center point and radius.
- How to Use: Select the Circle tool or type CIRCLE.
- Click to set the center point.
- Move the cursor to define the radius and click to complete.
c. Rectangle
The Rectangle tool creates rectangular shapes quickly.
- How to Use: Select the Rectangle tool or type RECTANGLE.
- Click to specify one corner.
- Move the cursor and click to specify the opposite corner.
d. Arc
The Arc tool is used to create curved lines.
- How to Use: Select the Arc tool or type ARC.
- Follow the prompts to specify the start point, second point, and endpoint.
Tip: Practice using these tools to create simple shapes and get comfortable with the command line prompts.
4. Editing Tools
Once you’ve created objects, you’ll often need to modify them. nanoCAD offers several editing tools to refine your designs:
a. Move
Relocate objects to a new position.
- How to Use: Select the Move tool or type MOVE.
- Select the objects.
- Specify a base point.
- Click to place the objects in the new location.
b. Copy
Create duplicates of selected objects.
- How to Use: Select the Copy tool or type COPY.
- Select the objects.
- Specify a base point.
- Click to place the copies.
c. Rotate
Rotate objects around a specified point.
- How to Use: Select the Rotate tool or type ROTATE.
- Select the objects.
- Specify a base point.
- Move the cursor to set the angle and click.
d. Trim and Extend
- Trim: Removes parts of objects beyond a cutting edge.
- Extend: Lengthens objects to meet a boundary edge.
Tip: Experiment with these tools to understand how they affect different objects.
5. Working with Layers and Properties
Layers help you organize your drawing by grouping related objects and controlling their visibility, color, and other properties.
a. Creating Layers
- Open the Layer Properties Manager by typing LAYER or selecting it from the menu.
- Click the New Layer button.
- Assign a name, color, and linetype.
b. Assigning Objects to Layers
- Select the objects.
- In the Properties panel, choose the desired layer from the dropdown.
c. Managing Layer Visibility
- In the Layer Properties Manager, turn layers on or off by clicking the lightbulb icon next to each layer.
Tip: Use layers to keep your drawings organized and manageable, especially as your designs grow more complex.
6. Introduction to Dimensions and Annotations
Adding dimensions and annotations ensures your design is clear and understandable.
a. Linear Dimensions
Measure distances between two points.
- How to Use: Select the Linear Dimension tool or type DIMLINEAR.
- Click two points to measure.
- Place the dimension line.
b. Text
Add notes or labels.
- How to Use: Select the Text tool or type TEXT.
- Click to specify the insertion point, then type your text.
c. Leaders
Point to specific parts with an arrow and text.
- How to Use: Select the Leader tool or type LEADER.
- Click to specify the arrow’s position, then the text position, and type your annotation.
7. Basic 3D Modeling Concepts
nanoCAD also offers basic 3D modeling capabilities, useful for creating simple 3D objects.
a. Creating 3D Primitives
- Create shapes like boxes, spheres, and cylinders.
- Example: Type BOX, specify the base point, and define the dimensions.
b. Extruding 2D Objects
- Turn 2D shapes into 3D objects.
- How to Use: Select the Extrude tool or type EXTRUDE, select the 2D object, and specify the height.
c. Viewing in 3D
- Use the View toolbar to switch to isometric views and see your model from different angles.
Note: Advanced 3D features are available in paid versions, but these basics are a great starting point.
8. Tips for Efficient Workflow and Productivity
Maximize your nanoCAD experience with these tips:
- Keyboard Shortcuts: Use L for Line, C for Circle, M for Move, etc., to speed up your work.
- Snap and Grid: Enable these from the status bar for accurate drawing.
- Ortho Mode: Press F8 to restrict cursor movement to horizontal and vertical directions.
- Save Frequently: Use SAVE or Ctrl+S to avoid losing progress.
