- AttachCopyToView( <物件>, <視區 0|1|2> )
- 若 <視區> 為 0，（會在主繪圖區）建立 <物件> 的應變副本。若 <視區> 為 1 或 2，會在指定的
（主、副）繪圖區建立 <物件> 的應變副本，但這些副本的尺寸會是常數。 - 範例：令
poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1))。
輸入AttachCopyToView(poly, 1)會在相同位置建立一個相同尺寸的正方形。 - 備註： 一旦副本建立後，GeoGebra 會自動在副本物件的定義補上其他四個引數到指令中（請參考下一個語法）。
- AttachCopyToView( <物件>, <視區 0|1|2>, <點 1>, <點 2>, <螢幕點 1>, <螢幕點 2> )
- If View = 0, a copy of given object is created. For View = 1 or View = 2 this command creates a dependent copy of given object whose size in given Graphics View is transformed using the affine transform that maps Point 1 to a point whose screen coordinates (in pixels) are equal to Screen Point 1, and Point 2 to a point with screen coordinates equal to Screen Point 2.
- 範例：Let
poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1)).
If Graphics View 1 is active,AttachCopyToView(poly, 1, (0, 0), (1, 1), (0, 0), (100, 100))creates a 100px x 100px square in the top left corner of the Graphics View. - 備註： All points of the object are copied, even if they lie outside the view.
