Understanding Revision Clouds
Revision clouds are visual symbols used in technical drawings to indicate areas that have been modified. These shapes consist of arcs connected in a wavy formation, making them stand out within the drawing without obscuring the details. They serve the purpose of guiding reviewers’ attention to the areas needing changes or close examination.
How to Create an Inverted Revision Cloud in AutoCAD
To draw an inverted revision cloud in AutoCAD, follow these systematic steps:
Step 1: Access the Revision Cloud Tool
Begin by opening your drawing in AutoCAD. Navigate to the Home tab on the ribbon. Look for the Draw panel, then click on the Revision Cloud drop-down menu. This is where you will find the tools needed to create and manipulate revision clouds.
Step 2: Select the Object
In the drawing area, right-click and select the Object option. This enables you to choose an existing geometric shape to modify into a revision cloud.
Step 3: Choose the Shape
Select a circle, ellipse, polyline, or spline that you want to convert into the revision cloud. Ensure that the shape is appropriate for the area in your drawing where you want to indicate revisions.
Step 4: Reverse the Cloud
To create an inverted revision cloud, you will need to modify the direction of the arcs. After selecting your shape, press Enter to keep the current arc direction initially. Then, right-click to access a context menu. Choose the option for Reverse or type “REVCLOUD” and select the revised cloud with a left-click. If necessary, confirm by typing “yes” to finalize the inversion.
Step 5: Adjust Arc Length if Needed
Should the arc lengths not meet your expectations, you can repeat the reversal process until you achieve the desired appearance. Continuously adjust until the inverted cloud fits well around the shape you selected.
Alternatives for Creating Revision Clouds
If you prefer not to convert existing shapes, you can create a revision cloud from scratch. Select the Revision Cloud function from the draw menu, then simply click and drag to outline the desired area directly on your drawing.
Using Revision Clouds Effectively
Revision clouds are not only for aesthetic purposes; they play a critical role in communicating changes to reviewers. When utilized, ensure that they are clearly visible and adequately represent the modifications made. Consider the context of your drawing and the audience reviewing it. Use a color that stands out yet complements the overall design.
FAQs
1. Can I modify the shape of a revision cloud after creating it?
Yes, once you create a revision cloud, you can use standard editing tools in AutoCAD to adjust its shape, add or remove sections, or change the direction of the arcs.
2. Is it possible to change the color of a revision cloud?
Absolutely! You can modify the color and line style of a revision cloud through the properties panel or by using the Properties command to make it more visually distinct.
3. Are there any shortcuts for creating revision clouds quickly?
Utilizing keyboard shortcuts or customizing your workspace can improve efficiency. Familiarize yourself with commands such as REVCLOUD that facilitate quicker access to the revision cloud tool.
