Essential Modify Operations<\/h2>\n
The Modify tab in the top bar features a collection of icons representing essential operations for manipulating, modifying, and editing sketches in the workspace. These tools, including moving, copying, rotating, scaling, mirroring, trimming, exploding, extending, offsetting, chamfering, filleting, and stretching objects, are invaluable for designers and can be used both in two-dimensional and three-dimensional spaces. Below are guidelines for utilizing some of the most vital modification tools.<\/p>\n
Move<\/h3>\n
The Move command enables users to relocate objects within the working space, regardless of the object\u2019s original coordinates. It\u2019s a vital tool for creating assemblies and is accessible in both the 2D environment (Draft and Annotations) through a cross arrow icon in the Modify tab, and the 3D environment (3D modeling) as MOVE 3D, indicated by a cross arrow with coordinate systems icon next to it.<\/p>\n
Alternatively, you can access this command by simply typing \u201cMOVE\u201d in the Command bar and selecting the appropriate option based on your working environment (2D or 3D).<\/p>\n
![\"Move\"](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/30.jpg\")
<\/p>\n
Copy<\/h3>\n
The Copy command can be found in the Modify section on the Home tab, as shown in the image below.<\/p>\n
![\"Copy\"](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/31.png\")
<\/p>\n
1. To duplicate an object, click the Copy icon and select the object you wish to copy.<\/p>\n
2. Then, specify the base point or coordinates where the copied object will be placed.<\/p>\n
![\"specify](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/32.png\")
<\/p>\n
3. To create additional copies of the same object, click on any point in the workspace and define a new base point. Press the ESC key when you have completed the copying process.<\/p>\n
Alternatively, you can also use the \u201cARRAY\u201d command in the Command bar to duplicate a group of objects.<\/p>\n
![\"Alternatively,](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/33.png\")
<\/p>\n
Rotate<\/h3>\n
The Rotate command enables users to change the position of an object by rotating it around a base point or a specified axis of rotation.<\/p>\n
The Rotate icon is placed in the Modify tab on the Home tab, as shown in the image below.<\/p>\n
![\"The](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/34.png\")
<\/p>\n
You can also access this command by typing \u201cROTATE\u201d in the Command bar at the bottom of the screen and pressing Enter.<\/p>\n
1. To rotate an object, click the Rotate icon and select the object you wish to rotate, and press Enter.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/35.png\")

![\"Next,](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/37.png\")
<\/p>\n
4. Once you have finished rotating the object, press the ESC key to exit the command.<\/p>\n
Scale<\/h3>\n
A scaled drawing represents an object graphically, where each dimension is either enlarged or reduced in a specific proportion (scale). When working in the modeling section of AutoCAD, there are two methods available for scaling drawings: using a scale factor or a reference figure.<\/p>\n
Scale Factor<\/h4>\n
If the scale is given or the ratio can be easily calculated (e.g., 1:2, 1:5, 3:1), the simplest approach is to type the scale factor.<\/p>\n
1. Select the object(s) you want to scale.<\/p>\n
2. Type \u201cSCALE\u201d in the Command bar and press Enter.<\/p>\n
3. Choose a base point for the object.<\/p>\n
4. Enter the scale factor and press Enter. If the number is between 0 and 1, it indicates scaling down, while a number greater than 1 represents scaling up.<\/p>\n
Reference Figure<\/h4>\n
In some cases, the user may not know the scale factor or the calculated result may be a continuous number (e.g., 1.345876\u2026) instead of an integer. In such situations, the user may be aware of the proportional size of the object or drawing in comparison to others. Other objects within the model space and images can serve as references. For example:<\/p>\n
1. Figure 1 serves as the reference object, while Figure 2 is the one to be scaled. To scale Figure 1 to the size of Figure 2, draw a radius line from the center of Figure 1 to the edge of the circle. (shown as a red line).<\/p>\n
![\"Figure](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/38.png\")
<\/p>\n
2. Select Figure 2, type \u201cSCALE\u201d, and press Enter.<\/p>\n
3. Click on the center point of Figure 1 as the base point.<\/p>\n
4. Click the end of the radius line as the scale factor.<\/p>\n
5. Press Enter, and now the circles should have the same size.<\/p>\n
![\"Press](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/39.png\")
<\/p>\n
Mirror<\/h3>\n
The Mirror command creates a mirrored copy of an object across a specific line, effectively creating its mirror image. The Mirror icon can be found in the top bar or accessed by typing \u201cMIRROR\u201d in the Command bar and pressing Enter.<\/p>\n
1. To perform the Mirror function, click on the Mirror icon and select the entire object that you want to mirror. Make sure that all the lines of the object are highlighted in blue.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/40.png\")
<\/p>\n
2. Next, AutoCAD will prompt you to choose the position for mirroring the object. If you want the mirrored object to be joined seamlessly, click on a corner that belongs to the boundaries of the object. This selected point will serve as the centerline of symmetry of the mirrored object.<\/p>\n
3. After locating the mirroring position, press Enter, and a mirrored copy of the object will appear on the screen. You can use the mouse to rotate or move this new object within the workspace as needed.<\/p>\n
![\"After](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/41.png\")
<\/p>\n
Trim<\/h3>\n
The Trim command allows users to selectively trim objects, lines, and shapes in their drawings. Users can choose to trim individual objects or select multiple objects by dragging the cursor or using the \u201cShift + Select\u201d method.<\/p>\n
To access the Trim command, simply click on the Trim icon located in the top bar or type \u201cTRIM\u201d in the Command bar at the bottom of the screen.<\/p>\n
The Trim command is similar to the Erase command, as their icons are located next to each other. The main difference is that the Erase command deletes the chosen element from the drawing without considering the surrounding edges and geometry. However, in certain cases, they can be used interchangeably depending on the specific scenario.<\/p>\n
![\"The](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/42.png\")
<\/p>\n

![\"Create](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/77.png\")
<\/p>\n
2. Ensure that the line or shape is open and joined.<\/p>\n
3. In the Command bar, type \u201cREVOLVE\u201d and press Enter.<\/p>\n
4. Click on the object you want to revolve and press Enter.<\/p>\n
5. Indicate the axis of rotation by clicking in the working space. The rotation axis doesn’t necessarily need to intersect with the shape’s endpoints; it can be placed at any point in the drawing space. Then press Enter.<\/p>\n
![\"Indicate](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/78.png\")
<\/p>\n
6. A dialog box will appear, allowing you to enter the revolution or spinning angle, ranging from 0 to 360 degrees. Alternatively, you can also use the mouse to establish the angle. Then press Enter.<\/p>\n
![\"A](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/79.jpg\")
<\/p>\n
The revolved object will immediately appear as a conceptual body.

<\/p>\n
Sweep<\/h3>\n
This Sweep command is a useful tool for representing pipes and circuits based on an open or closed 2D path and a cross-section. Here’s how you can perform a sweep.<\/p>\n
1. Begin by creating the open or closed path you want to sweep through. Use a polyline or straight-line figure, as shown in the image below.<\/p>\n
![\"Begin](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/81.png\")
<\/p>\n
2. Next, create the cross-section that intersects with the endpoint of the path and is perpendicular to the path’s plane.<\/p>\n
3. To ensure the correct alignment of objects in the drawing, switch to the Model View and verify that the cross-section is perpendicular to the 2D path. For example, the Top view model will face the cross-section.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/82.png\")
<\/p>\n
4. In the Command bar, type \u201cSWEEP\u201d and press Enter. Alternatively, you can access the Sweep icon in the Modeling tab.<\/p>\n
5. Select the cross-section and press Enter.<\/p>\n
6. Select the path (the 2D polyline) and press Enter.<\/p>\n
7. The solid will immediately appear in a conceptual view.<\/p>\n
Loft<\/h3>\n
The Loft command allows users to join two 2D shapes and create a 3D model or surface within the space that separates them. Unlike extruding, this operation involves creating a solid between two distinct cross-sections. Here is how you can use the Loft command.<\/p>\n
1. Ensure you have at least two 2D enclosed objects that are separated from each other along the axis perpendicular to the objects (typically the z-axis).<\/p>\n
2. To verify the location of objects in the drawing, switch to the Model View and ensure that both objects are in the same plane. For example, the Top view should show both objects separated vertically.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/83.png\")
<\/p>\n
3. In the Command bar, type \u201cLOFT\u201d and press Enter. Alternatively, you can access the Loft icon in the Modeling tab.<\/p>\n
4. Select the two desired objects, one after the other. As you select them, a coordinate system will appear on top of the cursor, indicating where the loft operation will occur. Press Enter to proceed.<\/p>\n
![\"Select](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/84.jpg\")
<\/p>\n
5. A solid will then appear in a conceptual view, as shown in the image below. You can always change the visual style of the solid by adjusting the settings.

<\/p>\n
Boolean Operations<\/h3>\n
AutoCAD provides powerful boolean operations that allow users to manipulate and optimize solid designs. These operations, namely Union, Subtract, and Intersect, are available exclusively in the 3D basics and 3D modeling environments.<\/p>\n
To access the boolean commands, navigate to the Modify section on the Home tab, located next to the Presspull icon.<\/p>\n
Note: <\/strong>Ensure that you have a minimum of two objects to perform any boolean operation, whether it involves joining, subtracting, or intersecting them.<\/p>\nUnion<\/h4>\n
1. Select the Union icon.
\n<\/strong><\/p>\n![\"Select](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/87.png\")
<\/p>\n
2. Use the mouse to select the objects you wish to join, and press Enter to complete the Union operation.
\n<\/strong><\/p>\n![\"Use](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/88.png\")
<\/p>\n
Subtract<\/h4>\n
1. For the Subtract operation, begin by selecting the object you want to retain after the subtraction.
\n<\/strong><\/p>\n![\"For](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/89.png\")
<\/p>\n
2. Next, select the object you want to eliminate, and press Enter to execute the Subtract operation.<\/p>\n
![\"select](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/90.png\")
<\/strong><\/p>\nFor example, the result of our example looks like this:<\/p>\n
![\"the](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/91.png\")
\n
\n<\/strong>In case of choosing the other object (the sphere) first, the result will change to look like this:<\/p>\n![\"In](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/92.png\")
<\/p>\n
Intersect<\/h4>\n
The Intersect operation functions similarly to the Union operation. The order in which you select objects does not matter.<\/p>\n
1. After selecting the Intersect tool, use the mouse to choose the objects you want to intersect, and press Enter to finalize the Intersect operation.<\/p>\n
![\"After](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/86.png\")
<\/p>\n
The resulting object will immediately appear on the screen, as shown in the image below.<\/p>\n
Working with 3D Meshes<\/h3>\n
A mesh is a 3D model composed of polygons with edges, faces, and vertices. Unlike solids, meshes are closed surfaces without mass.<\/p>\n
In the 3D modeling environment, 3D meshes have their own tab with mesh editing tools, as shown in the image below.<\/p>\n
![\"3D](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/95.png\")
<\/p>\n
Primitives<\/h4>\n
The simplest mesh tool is creating Primitives.<\/p>\n
1. Choose one of the default primitives provided by AutoCAD, such as a box, cone, cylinder, sphere, wedge, or torus.<\/p>\n
![\"Choose](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/96.png\")
<\/p>\n
2. After selecting a primitive, you can use the mouse to adjust its size and start exploring the mesh editing tools.<\/p>\n
3. Utilize the Selection section to manipulate the object\u2019s vertices, faces, or edges. Each option allows you to modify specific parts of the mesh.<\/p>\n
4. To flatten or extrude parts of the mesh, select the Face option.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/97.png\")
<\/p>\n
5. Choose the faces you want to modify and use the Gizmo to move them along the x, y, or z axes.<\/p>\n
![\"Choose](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/98.png\")
<\/p>\n
6. You can specify the height or distance by using the keyboard, and press Enter to complete the operation.<\/p>\n
![\"You](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/99.png\")
<\/p>\n
7. Switching to the Vertex option enables you to select one or multiple edges and move them within the workspace to shape the mesh. You can also establish a distance or height, as shown in the image below.<\/p>\n
![\"Switching](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/100.png\")
<\/p>\n
8. The process is similar when working with edges. Select the Edges option, click the edges you wish to manipulate, use the Gizmo to move them, and specify the distance.<\/p>\n
![\"The](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/101.png\")
<\/p>\n
Convert to Solid<\/h4>\n
After familiarizing yourself with the basics of editing primitive meshes, converting the mesh into a solid is a useful option.<\/p>\n
1. In the Convert Mesh tab, click on \u201cConvert to solid\u201d to transform the mesh into a solid, providing a smooth appearance to the object.<\/p>\n
2. Select the mesh you want to convert and press Enter. The object should be transformed into a solid body with a smooth shape, as shown in the image below.<\/p>\n
![\"Select](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/103.png\")
<\/p>\n
Working with Layers in AutoCAD<\/h2>\n
Layers are a useful feature in AutoCAD that helps users organize drawings by allowing them to temporarily suppress or hide unnecessary graphical data. Layers can be compared to clear, plastic sheets that contain information about the model, which can be overlapped to recreate all the details of a drawing. The Layer command serves various purposes in managing drawings, and becomes especially convenient when a sketch contains many objects and linetypes.<\/p>\n
Creating New Layers<\/h3>\n
To create a new layer, follow these steps.<\/p>\n
1. Click on the Layer Properties option on the main toolbar.<\/p>\n
![\"Click](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/104.png\")
<\/p>\n
2. In the Layer menu, you will see a default layer named \u201c0\u201d. Layer 0 is the pre-established default layer for all drawings and typically contains some default properties. To create a new layer, click on the icon that has a yellow star.<\/p>\n
3. From the Quick Access menu options, select the properties you want to incorporate into the new layer by clicking once in each cell. These properties can include the layer name, linetype, color, thickness, and visibility.<\/p>\n
![\"From](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/105.png\")
<\/p>\n
4. Use the Lightbulb icon to toggle the visibility of a layer, turning it on or off.<\/p>\n
Changing Layer Properties<\/h3>\n
1. In the Draft and Annotation environment, click the down arrow below the Layers icon and select the Layer Properties as shown in the image below.<\/p>\n
![\"In](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/106.png\")
<\/p>\n
2. A new window will immediately appear on the screen, displaying all existing layers and their associated parameters (such as color, linetype, lineweight, etc.).<\/p>\n
![\"A](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/107.png\")
<\/p>\n
3. To modify a parameter, click on the default value below each parameter and follow the provided instructions for each case, as shown in the images below. Press Enter after modifying each parameter.<\/p>\n
![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/108.png\")

![\"To](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/110.png\")
<\/p>\n
Annotations and Dimensions<\/h2>\n
Annotations and Dimensions allow AutoCAD users to provide important information about the design.<\/p>\n
Annotations<\/h3>\n
1. To display annotations in the workspace, navigate to the Annotation tab in the top bar and click on the Linear Dimension icon, located next to the Dimension icon. From the drop-down menu, select the annotation type, such as linear, aligned, angular, or radius, depending on the element you want to annotate in the drawing.<\/p>\n
2. After choosing the annotation type, click the starting measuring point, then select the ending point, and press Enter.<\/p>\n
3. The annotation will appear on the screen, and you can adjust its position by dragging it with the mouse, keeping in mind the space required for other annotations.
\n<\/strong><\/p>\n![\"The](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/111.png\")
<\/p>\n
Dimensions<\/h3>\n
The Dimension icon, also found in the Annotation tab, is a valuable tool for verifying measurements in a drawing. It displays the dimensions of specific parts of the sketch temporarily and offers options to measure radii, angles, volumes, and areas of objects.<\/p>\n
The process of measuring an object is similar to annotations, with the difference that once the dimension is shown on the screen, it will disappear after pressing Enter.<\/p>\n
This tool is particularly useful for checking dimensions without cluttering the drawing with excessive annotations.<\/p>\n
![\"This](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/112.png\")
<\/p>\n
Dimension Styles (DimStyle)<\/h3>\n
Dimension Styles, often referred to as \u201cDimStyles\u201d, are collections of settings that control the appearance of dimensions in a drawing. It\u2019s possible to create and modify these collections in AutoCAD.<\/p>\n
1. To change the DimStyle in the Model space, access the Annotation tab and click the drop-down menu to display the annotation options, as shown in the image below. Click on the second row in the drop-down menu next to the word \u201cStandard\u201d to access the Dimension Style Manager.<\/p>\n
![\"Click](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/113.png\")
<\/p>\n
2. A new window will immediately appear to create, modify, or compare DimStyles. Select the \u201cNew\u201d option if you are setting the dimension style for the first time, and select \u201cModify\u201d to change the parameters of an existing DimStyle.<\/p>\n
![\"A](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/115.png\")
<\/p>\n
If you select the \u201cModify\u201d option, a new section will appear with different parameters for you to adjust, such as Color, Linetype, Lightweight, and others, as shown in the image below.<\/p>\n
![\"If](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/114.png\")
<\/p>\n
The current DimStyle will be displayed at the top right, and the preview will update as you modify the parameters.<\/p>\n
![\"The](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/116.png\")
<\/p>\n
You can also change the units for the dimensions and customize tolerances, formats, and fonts to create a custom DimStyle.<\/p>\n
3. Once you have made all the desired changes, select \u201cOK\u201d.<\/p>\n
![\"Once](\"http:\/\/cad-kenkyujo.com\/en\/wp-content\/uploads\/2022\/11\/117.png\")
<\/p>\n
If you select the \u201cModify\u201d option, a new section will appear with different parameters for you to adjust, such as Color, Linetype, Lightweight, and others, as shown in the image below.<\/p>\n
