Polygons can be defined in two ways: either using an inscribed or circumscribed construction circle. An inscribed circle is defined on the inside of the polygon and is tangent to every side of the polygon. A circumscribed circle is defined on the outside of the polygon and passes through each endpoint of the polygon.
Both polygons are created with the same steps. Select a polygon from the dropdown list in the sketch toolbar.
Click to place the center of the circle, then drag the cursor out and click again to define the diameter of the circle. Move the cursor up or to the right to add more sides and down or to the left to remove sides. Once the desired number of sides is shown, click again to finish the polygon.
Immediately following the polygon placement, add a diameter dimension to the construction circle by typing a value and pressing enter.
A polygon can have between 3 and 50 sides. All the sides of the polygon are equal. To define the size of a polygon, dimension the construction circle or one of the polygon sides.
To edit the number or sides, double-click on the value, input a side count, and then press Enter. The orientation and location of the polygon can be constrained with dimensions and sketch constraints.
步驟
- Click
. - 按一下來開始。
- 拖曳來設定圓周。
請注意，為多邊形繪製的圓使用建構旗標。
這個時候您有兩個選項：
- 使用鍵盤來輸入邊數。然後按一下來鎖住圓周，會出現邊數的數值欄位：您可以再次使用鍵盤或拖曳來設定邊數。再按一下或按下 Enter。
- Click to lock the circumference and a value field appears for the sides: you can use the keyboard again or drag to set the number of sides. Click again or press Enter.
Drag towards the polygon to reduce the number of sides, click to set. Minimum sides = 3.
從多邊形朝外拖曳來增加邊數，按一下來完成設定。最多邊數 = 50。
又或者是在點按建立邊之後，馬上輸入直徑的數值 (或輸入 "=#" 並輸入變數)，然後按下 Enter。這樣可標註圓的尺寸而無需使用尺寸工具。
若要在繪製幾何之後將變數輸入至尺寸欄位中，並不需要有等號 (=)。輸入 "#" 並輸入變數。

步驟
- Tap to set the start point (center point) of the polygon.
- To set the second point (radius) of the polygon, tap again or touch and drag then release.
The number of sides appears in the middle of the polygon.
- 輕觸並繞中心點逆時針拖曳來減少多邊形的邊數。最少邊數 = 3。
- Touch and drag clockwise around the center point to increase the number of sides the polygon has. Maximum sides = 50.
When you release, the number of sides is set.
在您繪製多邊形草圖之後，預設會對下一個繪製的多邊形使用與之前繪製多邊形相同的邊數。
