The simplest geometrical object is a line. Select the "Line Tool". Draw a line by holding down the left mouse button and dragging. Release the mouse button where you want to end the line. Note that when you select the Line Tool, the Symbol Editor enters the Line mode and will stay in that mode until you change its mode. This means that once you finish drawing your line object, you can continue drawing new line objects. The Symbol Editor's default or normal mode is the "Select Mode". Click the "Select Tool" (white arrow) button on the toolbar to enter the Select Mode.

To draw a rectangle or ellipse, select the respective tool from the toolbar and click on the first corner point. Hold down the left mouse button and drag it in the right direction until to get the right size for your new object. In the case of an ellipse, the first corner point indeed corresponds to the bounding box of the ellipse. You can use the "Polygon Tool" to draw a closed polygon. You start a polygon just like a line. Every time you click the left mouse button you can change the direction of your polygon and add a new side. Single-click on the right mouse (or double-click with the left) to finish your polygon. You don't have to connect back to the original point. The polygon will automatically closes upon completion. To draw an arc, select the "Arc Tool" and first draw a full ellipse. Once your full ellipse is completed, a new varying radial line pops out of the center of the ellipse, whose ends follows the current location of your mouse. This allows you to set the start point of your arc. Click at the desired start point and drag the mouse either clockwise or counter-clockwise to stretch the arc. Then, click at the desired end point to finish your new arc object.
You can change the color of your lines and the boundaries of your objects from the default black. To do so, select one or more objects. Then select "Set Line Color..." from Symbol Editor's Edit Menu. This opens the color palette, where you can choose any desired color for your selected objects. You can set the thickness of the lines and object borders. By default, the line thickness is one point. To change an object's line thickness, first select the object and then select "Set Thickness..." from Symbol Editor's Edit Menu. Enter the desired value for the line thickness in the Thickness dialog. You can fill in rectangle, ellipse and polygon objects with any color. To fill in a object, first select it and then select "Set Fill Color..." from Symbol Editor's Edit Menu. This opens the same color palette, where you can choose your fill color. Symbol Editor's Edit Menu gives you more options to change or tailor your drawing. Some of these additional tools include rotating objects by 90 degrees, flipping horizontally or vertically, bringing objects to "Front" or sending them "Back" or grouping and ungrouping objects. <table><tr><td> [[File:b2MAN_Fig92.png|thumb|left|480px|Symbol Editor's Edit Menu.]]</td></tr></table>
