Click on the base point and drag an rectangle with the mouse.

Fix the end point with a mouse click.

Adjust the exact position (Base point X and Base point Y) and the dimension (Width and Height) in the docking window Edit element.

Click the center point.

Note If you want the center point to be snapped, you have to enable Snap to grid in the quick settings. Snap to grid

Note The Center point of a hexagon will not be a snap point later!

Drag the hexagon to the desired width and fix it with a mouse click.

Note If you want the width to snap at certain steps you have to enable Scalar parameters in the settings. "Scalar parameters" enabled

Note When dragging the hexagon you cannot affect the angle of rotation. The hexagon is always created with a start angle of 0°. If needed, adjust the parameters in the docking window Edit element.

-> In the docking window Edit element, Rotate selection is displayed.

If needed, adjust the Center point of the hexagon (Rotation point X and Rotation point Y) and the Angle of rotation.

In the Sketch history, select the point Insert hexagon.

-> In the docking window Edit element, now the view changes to Insert hexagon. Here, you can adjust Width across flats, furthermore, also here, the center point of the hexagon via Center point X and Center point Y.

Choose center point and Choose radius:

Click on the desired center point (not visible!) and drag the polygon with the cursor.

Note The Center point of a polygon will not be a snap later!

At the cursor position, an edge of the polygon is placed and so the Start angle is determined (which can be adjusted in the dialog Edit element later). If the point is on the horizontal, the Start angle is 0°.

Note If you want the center point to be snapped by the grid, you have to enable Snap to grid in the quick settings. Snap to grid

Note If you want the width to be snapped at certain steps, you have to enable Scalar parameters in the settings. "Scalar parameters" enabled

Through circular motion of the cursor around the midpoint, the number of corners changes.

The smaller the angle between the help lines, the larger the number of corners.

Fix the number of corners by mouse click.

-> If needed, adjust the single parameters in the docking window Edit element.
