How Do You Draw an Isometric Dimension in AutoCAD?

by

In this tutorial, we will learn how to draw an isometric dimension in AutoCAD. Isometric dimensions are commonly used in engineering and architectural drawings to represent objects in three dimensions. By following these steps, you will be able to create accurate and visually appealing isometric dimensions in AutoCAD.

Step 1: Set up the Isometric Drawing Environment

To start, open AutoCAD and create a new drawing.

  1. Click on the “Workspace Switching” button at the bottom-right corner of the AutoCAD window.
  2. Select “3D Modeling” from the list of workspaces.
  3. Click on the “View” tab at the top of the window.
  4. Select “3D Views” from the toolbar, then choose “Isometric” from the drop-down menu.

Step 2: Creating Basic Shapes

In this step, we will create basic shapes that will serve as reference points for our isometric dimension.

Create a Rectangle

To create a rectangle:

  1. Type “REC” in the command line and press Enter.
  2. Specify the first corner of the rectangle by clicking on a point in your drawing area.
  3. Type “@5,-5” (without quotes) and press Enter to specify the size of the rectangle. This will create a rectangle with a width and height of 5 units.

Create a Circle

To create a circle:

  1. Type “CIRCLE” in the command line and press Enter.
  2. Specify the center point of the circle by clicking on a point in your drawing area.
  3. Type “3” (without quotes) and press Enter to specify the radius of the circle. This will create a circle with a radius of 3 units.

Step 3: Applying Isometric Dimensioning

Now that we have created our basic shapes, let’s apply isometric dimensioning to them.

Create an Aligned Dimension

To create an aligned dimension:

  1. Type “DIMENSION” in the command line and press Enter.
  2. Select the first object you want to dimension, such as the rectangle or circle.
  3. Select the second object you want to dimension. Use the “Shift” key to select multiple objects if needed.
  4. Specify the location for your dimension by clicking on a point in your drawing area.

Create an Angular Dimension

To create an angular dimension:

  1. Type “DIMANGULAR” in the command line and press Enter.
  2. Select three points that define an angle. These points can be located on any of your previously created shapes.

Step 4: Fine-tuning the Isometric Dimension

After applying the isometric dimensioning, you may want to make some adjustments to enhance the clarity and readability of your drawing.

Move Dimensions

To move a dimension:

  1. Type “DIMREASSOCIATE” in the command line and press Enter.
  2. Select the dimension you want to move.
  3. Select a new location for your dimension by clicking on a point in your drawing area.

Edit Dimension Properties

To edit the properties of a dimension:

  1. Type “DIMSTYLE” in the command line and press Enter.
  2. Select the dimension style you want to modify or create a new one.
  3. Edit the properties such as text height, arrow size, or precision according to your preferences.

Congratulations! You have successfully learned how to draw an isometric dimension in AutoCAD.

By following these steps and utilizing various isometric dimensioning tools, you can create professional-looking isometric drawings for your engineering or architectural projects. Keep practicing and experimenting with different dimensions and shapes to enhance your skills further!
