How to Make a Construction Circle in SolidWorks?

Introduction to Construction Circles in SOLIDWORKS

Creating construction circles in SOLIDWORKS involves using specific tools and features within the software to facilitate design processes. Construction geometry is essential for sketching and acts solely as a reference in modeling, helping to organize dimensions and relationships without being included in the final part geometry.

Step 1: Start a New Sketch

To begin making a construction circle, first open SOLIDWORKS and create a new part file.

1. Click on New in the toolbar.
2. Select Part and click OK.
3. Navigate to the Sketch tab and select Sketch to start a new sketch.

Step 2: Choose Your Plane

Select a plane on which to draw your circle:

1. You can pick from the Front Plane, Top Plane, or Right Plane in the feature manager design tree.
2. Click on the plane you want to use; it will turn blue, indicating it’s selected.
3. Click on the Sketch icon.

Step 3: Access Circle Tool

To draw a circle, you need to utilize the Circle tool within the sketch interface.

1. In the Sketch toolbar, look for the Circle tool, represented by a circle icon.
2. Click on it to activate the circle-drawing feature.

Step 4: Draw the Circle

Now, draw your circle on the chosen plane:

1. Click on the desired center point where you want the circle to be located.
2. Move your mouse outward and click again to set the radius of your circle. The circle will appear on the sketch.

Step 5: Convert to Construction Circle

Next, you’ll convert the regular circle into a construction circle:

1. Select the circle you just created by clicking on it.
2. Right-click on the selected circle to bring up the context menu.
3. Find and choose the “For Construction” option from the menu. This action changes the visual style of the circle, typically indicating it is now a reference geometry and will not interfere with solid features.

Step 6: Finalizing the Sketch

After transforming your circle into a construction entity, you can continue working on your sketch or add more features as needed:

1. To check its properties, you can click on the circle and review it in the PropertyManager on the left side of the screen.
2. Finish your sketch by clicking on Exit Sketch once you have completed all desired sketch elements.

Frequently Asked Questions (FAQs)

How do I hide construction geometry in SOLIDWORKS?
To hide all construction geometry within a sketch, press the Shift and P keys simultaneously. This will toggle the visibility of construction elements without affecting any solid features.

Can I convert other sketch entities into construction geometry?
Yes, you can convert various sketch entities, including lines, arcs, and points into construction geometry. The method is similar: select the entity, right-click, and choose the “For Construction” option.

What is the purpose of using construction circles?
Construction circles serve as reference points in sketches and help maintain design constraints and dimensions without being part of the final 3D model. They aid in organizing the design process, ensuring accurate placements and alignments of other sketch entities.
