How To Blow Up Drawing In AutoCAD

Understanding Enlarging Drawings in AutoCAD

Scaling Drawings in AutoCAD

To enlarge a drawing in AutoCAD, you will utilize the SCALE command. Here’s how to do it step-by-step:

1. Select the Objects: Use your mouse to highlight the objects you want to enlarge. You can do this by clicking and dragging a window around them or by holding down the Shift key while selecting individual objects.

2. Activate the Scale Command: Type SCALE into the command line and hit Enter.

3. Set the Base Point: Choose a point that will serve as the reference for the scaling operation. This point is crucial, as it determines how the scaling affects the objects.

4. Input the Scale Factor: Enter a number greater than 1. The size of the selected objects will increase by that factor. For example, entering 2 will double the size.

5. Finalize the Command: Press Enter to apply the changes. Your selected objects should now be enlarged.

Creating a Blow-Up Drawing

A blow-up drawing, also known as an exploded view, illustrates the connection between various components of an object by showing them slightly separated from one another. This approach is particularly useful in assembly diagrams. Here’s how to create a blow-up drawing:

1. Select the Assembly Parts: Identify the parts of the assembly that you want to highlight.

2. Create an Exploded View: Use the appropriate commands or tools in AutoCAD to adjust the spacing between components, ensuring they are visibly separated while still indicating their relationships.

3. Adjust Viewports: If your drawing includes multiple views, ensure consistency across them for clarity.

Blowing Up Blocks in AutoCAD

Blowing up a block in AutoCAD requires careful manipulation to maintain the integrity of the block’s attributes. Follow these steps:

1. Select the Block: Click on the block you want to blow up.

2. Activate the Explode Function: Type EXPLODE in the command line and press Enter.

3. Confirm Your Selection: Click on the block again if required, and confirm the operation.

4. Use the BURST Command: For blocks with attributes, use the BURST command. This ensures that while the block components are separated, the attribute values remain intact.

5. Adjust as Necessary: After exploding and separating parts, manually adjust their positions for clarity and legibility.

Resizing Drawing Objects

To resize an object directly in AutoCAD, undertake the following steps:

1. Activate the Select Tool: Click the pointer tool in the Drawing toolbar.

2. Choose the Object: Click on the specific object you wish to resize.

3. Select a Handle: Hover over one of the blue handles on the selected object, click it, and hold down the mouse button.

4. Drag to Resize: Move the mouse to enlarge or shrink the object, then release the mouse button once you achieve the desired size.

Common Questions

1. Can I enlarge multiple objects at once in AutoCAD?
Yes, you can select multiple objects before using the SCALE command. The scaling will apply uniformly to all selected items.

2. What happens if I explode a block without the BURST command?
Exploding a block without using the BURST command will change the attribute texts into their tag values, potentially losing specific information tied to those attributes.

3. How do I keep my drawing’s scale consistent when enlarging?
To ensure consistency, verify your scale factors and use viewports to adjust your entire layout accordingly after modifying individual components.
