There are several ways to create a reference circle in FreeCAD for aligning other geometry like a hexagon: **1. Draft workbench - Construction Geometry:** * **Circle:** In the Draft Workbench, use the "Circle" tool. After creating the circle, select it. In the Data tab of the Property View, find the "Make Face" property and set it to `False`. This leaves the circle as a wireframe, ideal for reference. You can also directly toggle construction mode on before creating the circle. * **Other Draft shapes:** Similarly, you can create other construction shapes like polygons (including hexagons) directly in Draft Workbench with construction mode activated. These are perfect for reference and alignment. **2. Part workbench - Create a datum plane and sketch a circle:** * **Create a Datum Plane:** In the Part Workbench, use the "Create a datum plane" tool. This gives you a flat surface to work on. Attach this plane where it's convenient for your hexagon's location and orientation. * **Create a Sketch:** Select the datum plane and click "New sketch". * **Sketch a Circle:** Within the sketch, use the circle tool to draw your reference circle. The circle will remain within the sketch and won't be a solid object, making it suitable for reference. You can then use this sketched circle to constrain lines for your hexagon. You can even project the circle's geometry onto the sketch using the 'External Geometry' tool if the circle is defined elsewhere. **3. Part Design workbench - Create a datum plane and sketch a circle (similar to Part workbench):** The process is almost identical to the Part Workbench method. The advantage here is that you're working within a Part Design body, which is often preferred for more complex designs. **4. Using the Sketcher Workbench directly (if applicable):** * If you are already working within a sketch (e.g., on a face of a solid), you can create a construction circle directly within the Sketcher Workbench. Select the circle tool, and before clicking to define the center, press the 'C' key to toggle construction mode. The resulting circle will be blue and used only for reference within the sketch. **Using the reference circle to create a hexagon:** Once you have your reference circle, regardless of the method used, you can use it for alignment: * **Draft Workbench:** Use the "Polygon" tool. Snap the polygon vertices to points along the circumference of the reference circle. You might need to divide the circle into equal segments first using Draft's "Point" tool and snapping to the circle's quadrants/octants. * **Part or Part Design Workbench (within a sketch):** Use the "Polyline" tool and constrain the points of the polyline to the circle. Add constraints for equal length sides and equal angles to make it a regular hexagon. You can use the Coincident constraint to snap vertices to the circle. **Which method is best?** * For simple alignment tasks or 2D work, the Draft Workbench with construction geometry is often the quickest. * For more complex 3D models or when you need a reference circle on a specific plane, the Part or Part Design Workbench approaches are better. The Part Design Workbench is generally preferred if you are already working on a solid body. * The Sketcher Workbench method is excellent when you're already sketching and need a reference circle within that sketch. Remember to choose the method that best fits your overall workflow and the complexity of your model. Using construction geometry keeps your model tree cleaner and avoids unnecessary solid objects.

There are several ways to create a reference circle in FreeCAD for aligning other geometry like a hexagon: **1. Using a Draft Circle:** * Switch to the Draft Workbench. * Select the "Circle" tool. * Click to define the center point. * Enter the desired radius or click again to define it graphically. * This creates a Draft Circle object. While it's a "real" object, you can prevent it from being included in exports or 3D printing by making it invisible or moving it to a separate, non-exported group. **To make it invisible:** * Select the circle. * In the Property View, under the "View" tab, uncheck "Visibility." **To move it to a separate group:** * Create a new group (right-click in the Model tree -> Create group). * Drag the circle into the new group in the Model tree. * When exporting or 3D printing, simply don't include this group. **2. Using a Part Design Sketch with Construction Geometry:** This is a more robust method, particularly if you're working within the Part Design workbench: * Create a new Part Design Body. * Create a new sketch on a suitable plane. * In the Sketcher workbench, select the "Circle" tool. * Create your circle. * Select the circle in the sketch. * Click the "Construction Mode" button (it looks like a lightbulb) in the Sketcher toolbar. This makes the circle construction geometry. Construction geometry is only used for reference within the sketch; it doesn't become part of the final solid. * Now you can use the circle to constrain other geometry in your sketch, like the vertices of your hexagon. **3. Using a Draft Snap:** If you just need a temporary circle for snapping during drawing, you can use the Draft snap tools: * Switch to the Draft Workbench. * Start drawing the geometry you want to align (e.g., a line for your hexagon side). * Hold down **Shift** and hover your mouse over the center point where you'd like your reference circle to be. This activates various snap options. * Depending on your FreeCAD version, one of the following will be available: * A "Center" snap option might appear. Select it, and you can then enter the radius of your temporary snapping circle. * A "Relative" snap might be available. Select this, click the center point, then move your mouse and enter the radius value. * FreeCAD will display a temporary circle of that radius, and you can snap to points on its circumference. This circle won't be saved in the model. **4. Using the Attachment offset:** This allows you to offset a shape from another shape (like a hexagon from a circle) but keeps a parametric link: * Create your reference circle (either Draft or Part). * Create your hexagon (e.g., as a Draft Polygon or Part Design sketch). * Select the hexagon, then in the Property View, under the "Data" tab, find the "Attachment" property. * Click the "..." button to edit the attachment. * Choose the circle as the "Attached to" object. * Under "Attachment offset," you can define an offset distance (this would be the radius of your circle if you want the hexagon vertices on the circle). The best method depends on your specific workflow and whether you need the circle to persist in the model or just be a temporary aid. The Part Design Sketch with Construction Geometry is often the most flexible and powerful for design work. Draft Snaps are great for quick alignments. Using the Attachment offset is useful if you want the hexagon to always remain aligned with changes to the circle.

There are several ways to create a reference circle in FreeCAD for aligning other geometry like a hexagon: **1. Draft workbench - Draft Circle:** * Switch to the Draft Workbench. * Use the "Create circle" tool. * Draw your circle. * In the Property View (bottom panel by default), under the "View" tab, set the "Display Mode" to "Wireframe" or "Points". This visually distinguishes it as a reference and avoids confusion with solid geometry. You can also change its color to something like light gray to further emphasize its reference nature. This method is convenient for basic alignment tasks. The Draft circle is still a geometric object, but its visual representation is lighter. **2. Part workbench - Create a Datum Plane and sketch a circle:** * Switch to the Part Workbench. * Create a Datum Plane (click on the Datum Plane icon). This gives you a construction plane to work on. * Select the newly created Datum Plane. * Click on "New sketch". * Sketch a circle within the sketch. * Close the sketch. Sketches on Datum Planes are, by default, considered construction geometry and are not included in the final 3D model. This is an excellent way to create reference geometry. **3. Part workbench - Use a Part Design Additive cylinder and set it as construction:** * Switch to the Part Design workbench. * Create an Additive Cylinder. * In the Property View, under the "Part Design" tab, tick the "Construction" checkbox. This turns the cylinder into construction geometry. It will still be visible but won't be included in any boolean operations or final exported models. **4. Draft workbench - Draw a regular polygon (hexagon directly):** If your ultimate goal is to create a hexagon, the Draft Workbench offers a direct way: * Switch to the Draft Workbench. * Choose the "Regular polygon" tool. * Click to define the center point. * Move the mouse outwards to define the radius (the circle will be implied). * Enter the number of sides (6 for a hexagon) either in the input box that appears or by pressing the arrow keys. This creates the hexagon directly, bypassing the need for an explicit reference circle. **Using the reference circle/geometry for alignment:** Once you have your reference circle (or other reference geometry), you can use snapping tools to align your hexagon's vertices or edges: * Make sure snapping is enabled. Look for a magnet icon in the toolbar. * Select the appropriate snapping mode. "Endpoint," "Midpoint," "Intersection," and "Center" are likely to be useful. * When drawing or moving geometry, FreeCAD will highlight snap points on your reference circle, allowing you to precisely align your hexagon. The Datum Plane/Sketch method (method 2) is generally recommended for creating reference geometry, as it clearly separates construction elements from the main model. The Draft Workbench methods are quicker for simple alignments, and the direct hexagon creation is the most efficient if you only need the hexagon. Choose the approach that best suits your workflow and complexity of the model.

There are several ways to create a "reference circle" in FreeCAD that won't be part of your final object but helps you construct other shapes like a hexagon: **1. Using a Draft Circle:** * Switch to the Draft Workbench. * Use the "Circle" tool. * Create your circle of the desired size. * In the Property View (bottom-right panel, or View -> Panels -> Property View), find the "Visibility" property and uncheck it. This hides the circle visually, but it remains in the model tree and can be used for snapping and referencing. * Alternatively, instead of hiding it, you can change its "Line Style" to something like "Dash" or "Dot" to make it visually distinct as a reference element. **2. Using a Part Design Sketch and External Geometry:** This is a more robust method, especially if you're working with Part Design features. * Switch to the Part Design Workbench. * Create a new Body. * Create a new Sketch on a suitable plane. * Within the Sketcher workbench, use the "Circle" tool to create your reference circle. * **Crucially:** *Don't use this circle directly for any features*. Instead, when you create the hexagon (or other shapes), use construction geometry to reference the circle. For example, you might create construction lines from the center of the circle to the points where you want the vertices of your hexagon. Constrain these lines to be equal in length (using the equality constraint). The intersection points of these construction lines and the circle will define the hexagon's vertices. You can then create the hexagon edges by connecting those points. * Since the circle was never used to directly create a feature, it won't be part of your final solid, but it serves as a construction guide within the sketch. **3. Using a Datum Plane and a Draft Circle:** This approach is useful when you need the reference circle in 3D space, not just on a plane. * Create a Datum Plane (Part Workbench or Part Design Workbench) where you want the circle to be located. * Switch to the Draft Workbench. * Use the "Circle" tool. When prompted to select a plane, select the Datum Plane you just created. * Now you have a circle on the Datum Plane, which you can then use for reference similarly to the methods above (hiding it or changing its line style). **4. Using a Part Circle and Attachment:** * In the Part Workbench create a circle. * Attach it to a face or plane of your main object using the "Attachment Offset" feature. Set the "Map Mode" to "Plane" if you want it to lie on a specific planar face. * This will keep the circle dynamically linked to your main object, but it won't be part of its solid geometry. You can then reference it for other features or sketches. **Which method is best?** * For simple 2D constructions within a sketch, the **Part Design Sketch with External Geometry** is generally preferred. It keeps everything contained and organized. * If you need the reference circle in 3D space, the **Datum Plane with Draft Circle** or **Part Circle with Attachment** are better options. * For quick visual references and alignment in the Draft Workbench, simply hiding or changing the line style of a **Draft Circle** is often sufficient. Remember to select the appropriate snapping modes (e.g., endpoint, midpoint, center) to ensure accurate alignment when using your reference circle.

There are several ways to create a reference circle in FreeCAD for aligning other geometry like a hexagon: **1. Using a Draft Circle (Construction Geometry):** This is the most straightforward approach for a simple reference circle. * **Switch to the Draft Workbench.** * Select the "Circle" tool. * Click to define the center point. * Click again or enter a radius value to define the circle's size. * **Crucially:** In the Data Tab of the Property Editor (usually docked on the left), find the "Make Face" property and set it to `False`. This prevents the circle from being a solid face and makes it purely a reference object. Alternatively, you can right-click the circle in the Tree view and select "Toggle Construction Mode." **2. Using a Part Circle (Construction Geometry):** Similar to the Draft circle, but within the Part Workbench. * **Switch to the Part Workbench.** * Select the "Circle" tool. * Click to define the center point. * Click again or enter a radius value. * In the Property Editor, under the "View" tab, check the "Construction" box. This makes the circle a construction element. **3. Using a Sketcher Circle (for more complex setups):** If you're working within a Sketch (which is often used for more controlled designs), you can add a construction geometry circle within the sketch itself. * **Create a new sketch (on a face or plane).** * Select the "Circle" tool within the Sketcher workbench. * Create your circle. * Select the circle in the sketch and press the "Toggle construction" button in the Sketcher workbench toolbar (it looks like a lightbulb). This turns the circle into construction geometry within the sketch. **4. Using a Datum Plane and a Draft Circle:** For better control in 3D space: * Create a Datum Plane using the Part Workbench. Position it where you need the circle. * Switch to the Draft Workbench. * Create a Draft Circle on the Datum Plane. Make it a construction element as described in method 1. **Using the reference circle to create a hexagon:** Once you have your reference circle (using any of the above methods), you can use it to construct a hexagon: * **Draft Workbench:** Use the "Polygon" tool. Set the number of sides to 6. Snap the center of the polygon to the center of your reference circle. You can constrain one vertex to the circle to get the correct size. * **Sketcher Workbench (more precise):** Create a hexagon within a sketch, using constraints to relate its vertices or edges to the reference circle. You can then use the resulting hexagon sketch to create a Pad or Pocket. **Key advantages of using construction geometry:** * **Non-Exported:** Construction geometry doesn't get included in final exported models (e.g., STL, STEP). * **Reference Only:** It's specifically for aiding in design and doesn't become part of the solid model itself. * **Clearly Visible:** Construction geometry is typically displayed in a different color, making it easy to distinguish from your actual model. Choose the method that best suits your overall workflow and complexity of your design. For a simple hexagon based on a circle, the Draft Workbench method is probably the quickest. For more complex models, especially those involving sketches, the Sketcher Workbench method is usually preferred.
