In FreeCAD, creating reference geometry such as a circle to assist in aligning other elements like lines or shapes is a useful technique. For your specific need, to create a circle as a reference for constructing a hexagon or for other alignment purposes, you can use the "Construction mode" in the Sketcher Workbench. Here's how you can do it: 1. **Start a new project** in FreeCAD and switch to the **Sketcher Workbench** by selecting it from the drop-down menu in the top-left corner. 2. Click on **Create a new sketch** (you might need to choose a plane for your sketch, e.g., XY plane). 3. Once you are in the sketch environment, look for a button labeled **Toggle construction mode** or an icon that looks like a white triangle on a blue background (the appearance might vary slightly depending on your FreeCAD version). Click on this button to enter Construction mode. Anything you draw while this mode is active will be treated as reference geometry and will not be part of the final solid model. 4. With the Construction mode active (indicated by the geometry turning blue or another color different from your normal sketch geometry), choose the **Circle** tool from the toolbar. 5. Click on the center point where you want your circle and drag outwards to define the radius. Once you're satisfied with the size, click again to complete the circle. This circle will now act as a reference and won't be used to create solid geometry. 6. You can now use the **Polyline** tool or **Line** tool to draw the edges of your hexagon, using the reference circle to align the vertices equally around the center. Make sure to exit Construction mode if you want your hexagon to be part of the solid geometry by clicking the **Toggle construction mode** button again. 7. After completing your hexagon or other geometry, you can exit the Sketcher Workbench and use your sketches to create 3D models via extrusion, lofting, etc., in other workbenches like Part Design. Remember, construction geometry is very useful for guiding the creation of your designs without influencing the final solid model directly. It can be used for alignment, measurement, and as a guide for creating or positioning other sketch elements.

In FreeCAD, creating reference geometry to assist in designing more complex shapes like a hexagon is a common practice. To create a reference circle that you can use to align other elements without the circle being part of the final geometry, you can use "Construction Mode" in the Sketcher workbench. Here's how you can do it: 1. **Open FreeCAD** and switch to the **Sketcher workbench** by selecting it from the drop-down menu in the top-left corner of the interface. 2. **Create a new sketch** by clicking on the "Create a new sketch" icon. Choose the plane you want to sketch on and press OK. 3. **Activate Construction Mode**: Look for the toolbar button that shows two overlapping squares, one solid and one dashed. Hovering over it should display "Toggle construction mode" or a similar tooltip. Click this button to enter construction mode. In construction mode, anything you draw will be considered a construction element and won't be used to create solid geometry later. 4. **Draw your circle**: Select the circle tool from the toolbar or press 'C' on your keyboard, then click on the center point where you want your circle and drag out to define the radius. Because you're in construction mode, the circle will appear as a dashed line, indicating it's for reference only. 5. **Exit Construction Mode**: Click the "Toggle construction mode" button again to exit construction mode. Now, any new sketches will be part of the actual geometry. 6. **Sketch your geometry** (e.g., a hexagon) using the reference circle to align the vertices. To create a hexagon, you can use the polygon tool. Click the "Create a regular polygon" tool, set the number of sides to 6, and then click and drag to draw your hexagon, using the construction circle as a guide for positioning. 7. **Constrain your geometry**: Use the sketcher's constraint tools (like coincident, distance, or symmetry constraints) to precisely align the corners of your hexagon with the reference circle. This will ensure your hexagon is regular and properly sized. 8. **Finish your sketch** once you're satisfied with the geometry. Using a construction circle as a reference in this way allows you to accurately position and size other elements of your sketch without the circle itself becoming part of the final solid model. Remember, anything drawn in construction mode will not create solid geometry but is incredibly useful for guiding the creation of your design.

In FreeCAD, to create a reference geometry like a circle that you can use to align other elements (e.g., when creating a hexagon) without the circle being part of the final geometry, you can use the "Construction Mode" in the Sketcher workbench. Construction geometry is meant exactly for this purpose - to serve as a guide or reference for creating your main geometry without being part of the final shape. Here's how you can do it: 1. **Open FreeCAD** and switch to the **Sketcher workbench** by selecting it from the dropdown menu in the top-left corner of the interface. 2. **Create a new sketch** by clicking on "Create a new sketch" icon or through the menu by going to Sketch → New Sketch. Choose the plane you want to sketch on and click OK. 3. Now that you're in the sketch editing mode, look for the **Construction Mode** toggle. It's usually represented by an icon that resembles a white triangle and square. Clicking this will switch any geometry you create into construction geometry. The icon is typically located in the toolbar at the top of the sketcher interface or on the right-hand side, depending on your FreeCAD version and UI configuration. 4. With the Construction Mode active (you'll see the icon is highlighted or there's some visual indication it's active), **draw a circle**. Choose the Circle tool (icon with a circle) and place your circle in the sketch. Because you're in Construction Mode, the circle will appear in a different color (usually blue) indicating it's construction geometry and won't be part of the final extruded or padded feature. 5. **Create your hexagon**. Now you can use the construction circle as a reference to draw your hexagon. You can do this by creating points or lines that touch the circle's perimeter, ensuring that your hexagon is perfectly aligned. Remember to switch off the Construction Mode if you want your hexagon lines to be part of the final geometry. 6. After you've completed creating your hexagon aligned with the construction circle, you can finish the sketch. This construction geometry will not be visible in the 3D view outside the Sketcher workbench or be part of any 3D features you create from the sketch (like pads or pockets), serving purely as a guide for your design process.

In FreeCAD, one way to use a circle as a reference for creating shapes like a hexagon without the circle being part of the final sketch is by using construction geometry. Construction geometry allows you to create lines, circles, and other shapes that serve purely as guides or references for your design, without being part of the actual solid model you're creating. Here’s how you can do it: 1. **Open FreeCAD and Create a New Document**: Start FreeCAD and create a new document by clicking on "File" > "New". 2. **Switch to the Part Design or Sketcher Workbench**: You can switch to the Part Design or Sketcher workbench by selecting it from the drop-down menu in the top-left corner. The Part Design workbench is typically used for creating 3D parts, while the Sketcher workbench is focused on 2D sketch creation. Both can use construction geometry. 3. **Create a New Sketch**: Click on "Create a new sketch" (icon with a sketchpad and pencil) and choose the plane you want to sketch on, then click "OK". 4. **Drawing the Circle for Reference**: - Once in the sketcher environment, look for the circle tool (icon that looks like a circle) and click on it. - Click on your sketch plane to set the center of your circle, then drag outwards to set the radius and click again to place the circle. - With the circle still selected (it should be highlighted), look for the construction mode toggle in the toolbar. It's represented by a button showing two lines, one solid and one dashed, with a pencil over them. Clicking this button will change the selected geometry to construction mode (indicated by the geometry turning blue or dashed, depending on the version of FreeCAD). 5. **Drawing the Hexagon**: - Now, you can use the construction circle as a guide to draw your hexagon. Select the line tool (icon that looks like two connected dots). - Create the hexagon by snapping to the circle with the endpoint of your lines. This might require manually approximating the hexagon sides or using the "External Geometry" tool (icon with a chain link) to reference points on the construction circle directly if you need precise control. 6. **Finishing Up**: - Once your hexagon (or other shape) is complete, you can exit the sketch by clicking "Close" in the sketcher toolbar. - Your circle will remain as a part of the sketch but only as a dashed, non-printing line that serves as a reference, not as part of the solid model itself. Remember, the construction geometry is not just limited to circles; you can use it for any shape or line that you need as a reference. This feature is very useful for complex sketches where you need guides but do not want those guides to be part of the final extrusion or pad.

In FreeCAD, creating reference geometry (like a circle you want to use to align other elements) without it being part of the final solid model is a common practice. You can use various methods to achieve this, depending on your specific needs and the workbench you are working in. Here's a general approach using the Sketcher Workbench, which is commonly used for creating sketches that serve as the basis for 3D features. ### Steps to Create a Reference Circle for Aligning a Hexagon: 1. **Open Sketcher Workbench**: Start by switching to the Sketcher Workbench. You can do this by selecting it from the dropdown menu in the upper-left corner of the FreeCAD interface. 2. **Create a New Sketch**: Click on ‘Create a new sketch’ or go to `Sketch → New Sketch`. Choose the appropriate plane for your sketch and click `OK`. 3. **Draw a Circle**: - Use the circle tool in the Sketcher toolbar (it might just be an icon of a circle) to draw a circle in the sketch. This circle will serve as your reference for aligning the hexagon. - You don't need to worry about the size for now, as it's just for reference. 4. **Make the Circle Construction Geometry**: - Select the circle by clicking on it. You'll know it's selected when it's highlighted (usually turns green). - With the circle selected, click on the `Construction Mode` button in the Sketcher toolbar or go to the Sketch menu, look for `Sketcher geometries`, and then select `Toggle construction geometry`. This changes the circle into dashed lines, indicating it's now construction geometry and won't be used to create solid geometry later. 5. **Draw Your Hexagon**: - Now, with the construction circle as your guide, you can start drawing the hexagon. Use the `Polygon` tool in the Sketcher, set it to 6 sides, and start from one of the points where you want your hexagon to touch the circle. - Adjust the hexagon so that its corners touch the construction circle. This might require manually adjusting the points or using constraints to ensure they are equidistant from the center of the circle. 6. **Finishing Up**: - Once your hexagon is aligned as you wish with the construction circle, you can finish the sketch. - If you need to create a 3D object from the hexagon, you can now use it in the Part Design or another workbench to pad, extrude, or apply other operations without the construction circle affecting the outcome. ### Additional Tips: - **Use of Constraints**: Utilize geometric constraints (like horizontal, vertical, coincident, etc.) and dimensional constraints (to define distances, angles, etc.) to precisely control the layout of your sketch. - **Switching Between Construction and Regular Geometry**: You can toggle any sketch geometry between construction and regular geometry. This is useful if you initially draw something as a guide but later decide it should be part of the solid model, or vice versa. This method allows you to use reference geometry effectively in FreeCAD to guide the creation of your designs without the reference elements becoming part of the final solid model.
