The bottom part of the drawing board
includes some common functions we draw structural. In addition to the rich
chemical bonds, KingDraw also provides you with a charge, arrows, drawing element,
and bracket tool to help you draw various structural formulas and reaction
equations.
Charge tool
A charge tool can increase or decrease the
amount of charge for an element. Press and hold the charge tool to switch
between positive and negative charges.
After selecting the positive/negative
charge, clicking on the element to add a positive/negative charge to the element.
Multiple clicks can continue to increase the amount of charge.
It is currently not supported to add charge
directly to text, parentheses, arrows, or groups.
Arrow tool
Arrow tool can be used to show the
conversion of reactants to products, as well as indicate the direction of
electron flow.
KingDraw currently offers three arrows,
solid arrows, hollow arrows, and angled arrows. Select the desired arrow and
click on the artboard to generate it. Press and hold to adjust the length and
angle of the arrow. You can also combine with marquee and color tool to change
the size and color.

Drawing Element tool
The drawing element tool contains a variety
of hollow models, solid models, lines, circles, ovals, arcs etc., to help you
quickly group drawing elements.
Use the same method as the arrow tool.
Select the desired model and point where you want. Drag outward to adjust the
length and width of the graphic.
Bracket tool
Brackets include 3 forms. All are paired.
The parentheses is used in a similar way to
other tools. Select the desired one and point where you want the bracket to
start. Drag from one end of the bracket to the other end.
