Currently, most industries and fields need unique and creative designs. Therefore, learning to design gradually becomes a new trend for everyone. Typically, learning to use AutoCAD software.
But many people are worried because they don’t know where to start with AutoCAD. Therefore, in this article, we decided to guide you on how to learn AutoCAD effectively and help you understand the basic operations of the CAD software through 6 steps:
- Define interface
- Sketch 2D
- Create 3D models
- Moving and aligning objects
- Technical drawings
- Working with Meshes
To find out in more detail, we come to each of the basics later.
What Is AutoCAD?
For those of you who don’t know, CAD stands for Computer-Aided Design. As the name suggests, AutoCAD allows you to draft and design data on your computer. You should check this list best laptop for autocad.
If we talk about the popularity of design software, AutoCAD is confident to be a top 1 software. It is not surprising that AutoCAD achieves this achievement because this software was born early, and Autodesk does not stop maintaining and developing it.
As a result, AutoCAD brings a high degree of flexibility and has become the standard of many current fields such as mechanical, engineering, industrial, architecture, and art. Overall, if you want to design, AutoCAD is ready to respond to you fully.
In terms of functionality, AutoCAD allows you to use it for various applications and design projects in your specialty. In addition, the software also provides us with CAD models and most of the virtual 3D models that are appearing today.
6 Basic Steps On how to learn autocad For Beginners
Do you know how to learn autocad? Overall, learning AutoCAD is not too difficult. To help you better understand how to use it, we have detailed instructions through 6 steps. If you follow the instructions below correctly, you can completely master Autocad even if you don’t have much experience.
Step 1: Define the user interface
First, a pretty important step that no one can skip is defining the user interface.
Here, you will get acquainted with the user interface first. In addition, you also need to understand how to interact with the application and set up the workspace. Thus, your manipulation design process with AutoCAD will not be too much trouble.
After opening the software interface, click on the “Start drawing” box to display the main screen. Basically, the screen interface will include:
- The quick access toolbar contains action icons such as: “Open,” “Save,” and “New Project.”
- The Ribbon includes many different basic tools and commands that fit into tabs on the screen.
- Command bar: here allows you to enter orders manually.
We will start getting acquainted with the Viewcube and NavBar of the software interface about the basic orientation.
- View cube is an icon located in the upper right corner of the screen by default. Or the Viewcube can also turn into a small house if your mouse moves.
- Next, you can click on the view cube to select an isometric view. Then, the Cartesian 3D coordinate system appears with three axes. You can select any faces, edges, and corners to convert to the shape you want.
NavBar often comes with navigation tools, but for CAD, the preference is always for keyboard shortcuts.
You can use the NavBar by holding the wheel button, moving the mouse around, and selecting the “hand” on the NavBar.
Or, for holding Shift and rolling the mouse, you will also draw at the center of the predetermined coordinate system.
Next, we’ll finish setting up the workspace so we can start 2D sketching.
Set up a workspace
To set up a 3D workspace, we need to enable the “Workspace” mode by:
- Clicking the arrow on the quick access toolbar and selecting the “Workspace” displayed on the screen.
- Next, you replace “Edit & Annotate” with the word “Create 3D Model” in the menu. Now you can fully use all 2D and 3D models in the application.
- Finally, change the unit to (mm) by:
- Click on the red ‘A’ icon in the top left corner.
- Check the box “Drawing Utilities–> Units.”
- Change “Insert scale” to millimeters to make it easier to design.
Step 2: Sketch 2D EASY
Before we dive into 3D modeling, let’s look at 2D sketches for floor plans and layouts.
To sketch with AutoCAD, you must switch to the Grid snapping feature. We will have 2 ways to open Grid Snap as follows:
- 1st: select F9 on the keyboard.
- Second: select “Snap to Drawing Grid” in the bottom right corner of the screen.
- After opening the feature, continue to do the following actions:
- Click on the arrow next to “Hold to Draw Grid Button.”
- Select “Shooting Settings.”
- Enable “Object Snap” when this Tab is visible
- Now you need to press F3 to trigger the snap of everything.
- In addition, if you want to capture only one object, select “Tangent” to enter the image coordinates with visual style.
A little trick for when you can’t enter coordinates and outlines: turn the “Snapshot” icon on or off. Then you continue to disable one of the two functions (Grid and Object Snap). The sketch will then return to normal.
Draw a line
To draw a line, you must follow these steps:
- Select Viewcube and disable Grid Snap.
- Click the “line” command on the Ribbon or enter “line” in the search field.
- Now that the setup is complete, you can start sketching the line by selecting any center point or entering the coordinates of the topic you want to draw.
Here are some examples:
- Select the center of the coordinate system (0,0) and confirm by pressing Enter.
- Enter the length of the line as you want and by pressing Tab. A straight line will appear when you press Enter.
You can select objects by left-clicking on them. Or left-click (don’t hold) and move the mouse left to right when you want to select multiple objects.
To deselect an object, you would hold down the Shift key and click again.
In general, drawing shapes is quite similar to drawing lines. However, drawing shapes requires a little more.
Click the “Rectangle” box on the ribbon or type “rectangle” in the command bar. Select the line-like origin as (0,0) and press Enter.
Then enter the lengths of the sides in turn and press Enter; a rectangle will appear.
To draw a circle, enter the coordinates of the center and the radius. But for ellipses, there will be a different main radius and minor radius.
In addition, you can also draw many other images. Regarding the command, the other figures are similar to the above. However, they have some coordinate changes. But in general, filling in the coordinates is not too difficult, so we will not guide you further.
If you want to practice and learn more with this step, then you can refer to the following video:
Step 3: Create 3D model
Autocad electrical 3D modeling allows you to design and print into 3D products. Overall, creating 3D models is not too difficult. Here are the basic instructions:
Create basic shapes
To create basic shapes, you can start with some live modeling tools. We use predefined shapes like spheres and cubes to create objects through Boolean operations (union, subtraction, and intersection).
- First, switch to an isometric view as we guide above. Then you create the shape you want, like a circle, rectangle like step 2.
- To create a 3D process, enter “sphere” and center it at (0,0). Next, you enter an arbitrary size in millimeters. As for the rectangle, enter the “box” and do the same.
- However, the object is still very rough, and you need to align it further.
Carrying out the alignment
In this step, depending on your desire for the design, you will have different adjustments.
Here, AutoCAD allows you to make a lot of adjustments such as:
- Change image
- Solid, angular modeling
- Rotate, change direction
- Staggering order, vision
- Scan pictures
All of them are located in the Ribbon bar on the screen. Your job is to select a mode then press to confirm. So you can edit as you like in your design.
Step 4: Move and align objects
If you need to move, transform or nest 3D models together, this section is for you.
- To make it quick, we’ll list each step as follows:
- Enter “3D Move” and confirm.
- Select the object to move.
- Press enter.
- Continue to select a point on the shape and press Enter to start moving.
Actually, you can move the image in a lot of different ways. Here, we’ll walk you through some of the basics:
- Move with mouse over
- Move by entering the distance and direction of movement through the coordinates of the shape.
- Use linear translation through the XYZ axes.
- Move by the arrow in object selection.
Please type “Rotate 3D ” to rotate the image,” then select the object and press Enter. You can now use the mouse to rotate the things interior designers aim at.
In this section, AutoCAD allows us to use many alignment tools, but we will only show you how to use 3D Align. Because this way helps you to operate the fastest.
First, you also need to select “align” and confirm. Then you choose the object and press Enter. Now you can comfortably align images with your keyboard mouse or basic math operations.
Step 5: Technical drawing
After you have yourself a model on AutoCAD, we will come to the technical drawing step.
A nice little trick to help you avoid the trouble of drawing is to bring the subject into a separate drawing space. Here’s how:
- Right-click on the “+” sign (bottom left corner)
- Then you click “From Template.”
- And finally, select the “Tutorial-mMfg” template to convert the space.
Insert Model View
- To see the entire model before the end, select “Layout” at the Ribbon and then select “Basic -> From Model Space.”
- At this point, a small window will appear and take you to the general view.
- Here, you can change many modes by selecting the “Orientation” box and pressing enter to confirm. In addition, you can also change the scale to see better when selecting “scale”.
To avoid missing sectional views in engineering drawings, let’s go to section view:
- To view the section, please select “Layout -> Section View” and choose a picture of your choice, then press enter to confirm.
- At this point, you can view each of the different sections and projections of the drawing.
Step 6: Working with Meshes
In step 6, we will learn about meshes, one of the very important things for 3D printers. Specifically, you will need to create or edit the grid file accordingly through the following ways:
Import STL and other grids
Because you can’t 3D print with mesh files natively, AutoCAD includes a standard format handling section to help you convert objects to exchange formats such as STEP or DWG and DXF.
There are many ways to convert meshes to such file formats. However, we only show you the simplest way. This way, you need to upload the file to the STL of the online converter from the CAD-Forum provider. The tool will then help you convert the file to DWG or DXF format.
Alternatively, you can also use the Fusion 360 CAD program or FreeCAD software to perform the conversion.
Export STL file
In general, exporting STL files is not difficult. You need to select “AutoCAD Logo -> Export -> Other File Formats” and choose the file type. Finally, a 3D print is complete, and you can start directly printing the drawing now if you want.
