To add a Polygon to the graphics pane The primary portion of the GoldSim interface, where the graphical depiction of the model is shown.:
- Select Polygon from the drop-list at the first button of the Graphical Tools toolbar or the main menu under Graphics|Insert.
- Place the cursor at the location in the graphics pane where you want one of the corners of the polygon to be and click.
- Move the cursor to the next vertex of the polygon and click.
- After adding as many vertices as desired, move the cursor to the location where you want the last vertex of the polygon to be and double-click.
You can move a polygon by selecting it and dragging it around the graphics pane. You can "stretch" a polygon by selecting the object and dragging one of the "handles" (there are eight handles - one on each corner and one on each side). Pressing the Shift key while resizing the object keeps the same aspect ratio; pressing the Ctrl key while resizing keeps the center of the object at the same location.
You can also move individual vertices by right-clicking on the object and selecting Edit Vertices from the menu. This will highlight individual vertices that can then be dragged and repositioned.
You can rotate a polygon by selecting the object and choosing Graphics|Rotate from the main menu.
