### Understanding Extrusion in AutoCAD
Extruding an array in AutoCAD requires several steps. It’s essential to know that you can’t directly extrude an associative array. To achieve this, first, you must break the array down into individual components by using the “EXPLODE” command. This allows you to manipulate each element separately.
### Step-by-Step Guide to Extrude an Array
#### 1. Create Your Design
Begin by drawing the shape that you intend to extrude. For instance, you can create a single circle or any closed profile that you wish to work with.
#### 2. Create an Array
Once your shape is ready:
– Navigate to the **Home** tab.
– Click on the **Modify** panel and select **Polar Array**.
– Choose the object you want to replicate.
– Specify a center point for the array.
– Enter the number of items you want in the array and set the angle to fill.
#### 3. Explode the Array
With the array created:
– Use the **EXPLODE** command by typing `EXPLODE` into the command line or selecting it from the Modify panel.
– Click on the array to break it into individual elements. Each piece can now be manipulated separately.
#### 4. Selecting Objects for Extrusion
Now that you have independent objects:
– Click on the **Solid** tab within the **Solid** panel.
– Select the **Extrude** option.
– Click on each object or edge subobject that you want to extrude.
#### 5. Specify Height
After selecting the objects:
– Enter the height you want the objects to be extruded to. You can specify a positive value for an upward extrusion or a negative value for a downward extrusion.
#### 6. Finalize the Extrusion
Once you have specified the height, press `Enter` to complete the extrusion. Your newly extruded shapes should now appear in the model space accordingly.
### Additional Methods for Creating Arrays
It’s also possible to create an array with the associative option, which allows for easy adjustments. When creating the array:
– Make sure to select the **Associative** option. This ensures that any changes made to the original objects will automatically update in the array copies, reducing the need for future adjustments.
### FAQs
**Q1: Can I extrude an array directly without exploding it?**
No, you must first explode the array to convert it into individual objects before applying the extrusion.
**Q2: What types of objects can I extrude in AutoCAD?**
You can extrude closed shapes, including circles, rectangles, and other polylines. Open shapes or lines need to be enclosed first.
**Q3: How do I adjust an existing extruded shape?**
To modify an extruded shape, select the object and use the **Properties** panel to change the extrusion height or create additional modifications using commands such as **Scale** or **Move**.
