You can achieve this in FreeCAD using a few different methods: **1. Using a Construction Circle:** * **Sketch Workbench:** 1. Create a new sketch on the plane where you want your hexagon. 2. Select the **Circle** tool. 3. Before clicking to define the center, **press and hold the CTRL key**. This will create the circle in "construction" mode. 4. Click to define the center and drag to set the radius. 5. Draw the lines of your hexagon using the construction circle as a guide for snapping endpoints or defining angles. * **Part Design Workbench:** 1. Similar to the Sketch Workbench, you can create a construction circle within a **Part Design Body**. This allows for more complex 3D relationships later if needed. **2. Using a Draft Snap:** * **Draft Workbench:** 1. Create a regular polygon using the **Polygon** tool. Set the number of sides to 6 for a hexagon. 2. Even though you can't see the circle directly, the polygon's center acts as a snap point. 3. Use other Draft tools like **Line** or **Wire**, and take advantage of the snap options (make sure "Center" snap is enabled) to align your geometry to the polygon's center. **3. Using a Temporary Construction Line:** * **Any Workbench:** 1. Use the appropriate line tool (e.g., **Line** in Draft Workbench, **Line** in Sketcher Workbench) to draw a line that passes through the desired center point of your hexagon. 2. Draw another line perpendicular to the first, also passing through the center. 3. The intersection of these lines now acts as a temporary reference for your hexagon's center. 4. You can delete these construction lines after you've created your hexagon. **Key Points:** * **Construction Geometry:** Objects created in construction mode (using CTRL) appear in blue and are not included in the final exported geometry. They are purely for reference. * **Snapping:** Make sure snapping is enabled in your preferences to easily align objects to reference points. Remember to select the method that best suits your workflow and the complexity of your design.

You have a few options in FreeCAD to achieve this, depending on exactly how you want to use the circle as a reference: **1. Using a Construction Circle (Draft Workbench)** * **Advantages:** Easy to create, clearly visually distinct from regular geometry. * **Best for:** Quickly setting up reference points for other shapes. 1. **Switch to the Draft Workbench.** 2. **Use the "Circle" tool.** Specify the center point and radius. 3. **Your circle will be created as a "Draft object".** These are automatically placed on the "construction" layer which is typically displayed in a different color and considered non-geometric. **2. Using a Sketch with Construction Geometry (Sketcher Workbench)** * **Advantages:** More precise control, allows for constraints. * **Best for:** Precisely aligning lines of your hexagon to specific angles. 1. **Create a new sketch.** 2. **Use the "Circle" tool within the Sketcher Workbench.** 3. **Select the circle in the sketch and toggle it to "Construction" mode.** You can find this option in the Sketcher toolbar or by right-clicking the circle. 4. **Now draw the lines of your hexagon, using constraints to snap them to the circle's quadrants or other points.** **3. Using a Temporary Construction Circle (Part Design Workbench)** * **Advantages:** Circle only exists while creating the hexagon, keeps your model clean. * **Best for:** Streamlined workflow if you're building the hexagon directly. 1. **Start a new body and create a sketch.** 2. **Use the "Circle" tool.** 3. **Don't leave the circle tool yet!** Immediately draw your hexagon lines, snapping them to the circle's points. 4. **Once your hexagon lines are complete, you can cancel the circle tool.** The circle will disappear, leaving only your hexagon. **Important Note:** Regardless of the method you choose, remember that construction geometry won't be included in any 3D operations like extrusions or Boolean operations. It's purely for reference.

You can achieve this in FreeCAD using a couple of methods: **1. Using a Construction Circle:** * **Sketch:** Start by creating a new sketch on the plane where you want your hexagon. * **Construction Geometry:** In the Sketcher workbench, find the toolbar button for "Toggle construction mode" (it looks like a blue/white compass). Click this to activate construction mode. * **Draw the Circle:** Now, use the circle tool to draw a circle at the origin. Since you're in construction mode, this circle will be blue and treated as reference geometry – it won't be included in extrusions or other operations. * **Create the Hexagon:** Use the polygon tool to create a hexagon. You can snap its vertices or edges to the reference circle to ensure alignment. **2. Using a Draft Construction Line:** * **Draft Workbench:** Switch to the Draft Workbench. * **Construction Line:** Use the "Line to Point" tool (or similar) in construction mode. Create lines that represent the radii or diameters of your desired circle. You can set specific lengths if needed. * **Hexagon:** Return to the Sketcher Workbench and create your hexagon, snapping its points to the intersections of your construction lines. **Additional Tips:** * **Constraints:** Use geometric constraints (like coincident, point on object, equal length) to precisely position your hexagon's points relative to the reference circle or lines. * **Visibility:** If you want to temporarily hide the reference geometry, you can toggle its visibility in the Model tree. **Example (Using Construction Circle):** 1. **Start:** Open FreeCAD and create a new document. 2. **Sketch:** Create a new sketch on the XY Plane. 3. **Construction Mode:** Click the "Toggle construction mode" button in the Sketcher toolbar. 4. **Circle:** Use the circle tool to draw a circle centered at the origin. 5. **Polygon:** Choose the polygon tool and set the number of sides to 6 (for a hexagon). Click to place the center of the hexagon, then click again to define its size, snapping to the circle for accuracy. 6. **Exit Sketch:** Close the sketch. Now you have a hexagon perfectly aligned with the reference circle, which itself won't be part of any solid model you create from the hexagon.

You have a couple of options to achieve this in FreeCAD: **1. Using a Construction Circle:** - **Construction Geometry:** FreeCAD allows you to create "Construction" geometry. These objects are purely for reference and won't be included in your final exports or operations like Boolean operations. - **Steps:** 1. Switch to the **Draft Workbench**. 2. Select the **Draft Circle** tool. 3. Click to define the center point of your circle. 4. Enter the desired radius in the dialog box or drag to visually set the radius. 5. **Crucially, in the Draft Circle's properties panel, find the "Make Face" property and set it to "False".** This ensures the circle is only a wireframe reference. **2. Using a Sketch and External Geometry:** - **Sketches and Constraints:** This method leverages FreeCAD's powerful Sketcher Workbench, which is ideal for precise 2D geometry creation. - **Steps:** 1. Create a new **Sketch** on the XY plane (or your desired plane). 2. Switch to the **Sketcher Workbench**. 3. Use the **Sketcher Circle** tool to draw a circle within your sketch. You don't need to worry about its size being exact at this point. 4. Now, use the **Sketcher Point** tool to place six points around the circle where you want the vertices of your hexagon to be. 5. **Important:** Select the circle and, in its properties, look for the "Construction" option and enable it. This turns the circle into reference geometry within the sketch. 6. Use the **Sketcher Line** tool to connect the points you created, forming the sides of your hexagon. 7. Constrain your hexagon as needed (e.g., equal side lengths, parallel lines) to make it regular. **Using Your Reference Circle:** Regardless of the method you choose: - **Snapping:** Enable snapping in FreeCAD's options, and use the convenient snapping points that appear on the reference circle (center, quadrant points) to accurately position your hexagon's vertices or lines. **Which Method to Choose:** - **Construction Circles (Draft Workbench):** Great for quick reference circles that you might use across multiple objects or operations. - **Sketches (Sketcher Workbench):** The preferred choice for creating precise 2D shapes like hexagons, especially if you need to apply geometric constraints for accuracy. Let me know if you have any other questions!

You're looking for a **construction geometry** feature in FreeCAD. Construction geometry helps you define shapes and positions without being part of the final object. Here's how to use it for your hexagon example: **Method 1: Using a Construction Circle and Polygons** 1. **Create a Construction Plane (Optional):** If you want your hexagon on a specific plane, start by creating a construction plane (Part workbench > Plane). 2. **Create a Construction Circle:** * Switch to the **Draft Workbench**. * Select the **Draft Circle** tool. * In the "Tasks" tab, check the box for **"Make Face"** to disable it. This is crucial, as it makes the circle construction geometry. * Click to define the center of your circle. * Enter the desired radius in the dialog box or click to set it graphically. 3. **Create a Hexagon:** * Stay in the **Draft Workbench**. * Select the **Draft Polygon** tool. * In the "Tasks" tab, set the **Number of Sides** to "6". * Click on the circumference of the construction circle to define the first point of your hexagon. FreeCAD will snap to it, ensuring accurate placement. * Define the hexagon's size by clicking again or entering a value for the radius/diameter. 4. **Hide or Delete the Construction Circle (Optional):** Right-click on the construction circle in the Tree View and select "Hide" or "Delete." **Method 2: Using a Construction Circle and Lines** 1. **Create a Construction Circle:** Follow steps 1 and 2 from Method 1. 2. **Create Construction Lines:** * Switch to the **Part Workbench**. * Select the **Line** tool. * Snap the start and end points of lines to the circumference of the construction circle to create the sides of your hexagon. 3. **Hide or Delete the Construction Circle (Optional):** As in Method 1. **Additional Tips:** * **Construction Geometry Color:** Construction geometry typically appears in a different color (often blue or green) to distinguish it from the main model. * **Toggling Visibility:** You can easily show or hide construction geometry using the "Show/Hide" toggle in the Tree View. * **Constraints:** Use FreeCAD's constraint tools (like coincident, parallel, perpendicular) to precisely position the hexagon's points in relation to the construction circle. Remember, construction geometry won't be included in your final exported model or 3D print. It serves as a helpful guide during the design process.
