Introduction to the KingDraw App Drawing Board


The KingDraw App is the world's first, professional mobile chemical structure editor. Powerful built with rich chemical drawing elements, KingDraw can greatly improve the speed and accuracy of drawing chemical structures. What’s more, all the services are free now.

For many chemists who are new to KingDraw, it may be a little unfamiliar to see so many features when opening the drawing board. Today we will introduce in detail the various functions on the sketchpad, you will find that KingDraw is really easy~~

KingDraw App Drawing Board Overview
  


Open the KingDraw App, click the plus button to create a new file, and you'll see the drawing board. Here are all the functions to draw the chemical structure. The drawing board is divided into four functional areas: up, down, left, and right. Next, we will show you the functions of each area in detail.

Upper functional area - common operating tool area

  




The upper toolbar of KingDraw App are mainly includes common functions used in drawing.

1. Return: Close the current drawing board page and return to the main interface;
2. File naming: Modify the current file name;
3. Save: Save the current file;
4. Save as: Save the current file as other common formats. The current version supports conversion of king, .cdx, .mol, .molv3000, .png formats;
5. Eraser: Erase the contents on the drawing board, long press to switch to the”Clear” tool
6. Color tool: Set up the color to the specified position of the chemical structure;
7. Alignment tool: Set up the alignment and stacking position for the specified chemical structure;
8. Box selection tool: Select all or part of the chemical structure for other operations; long press to switch to the “lasso” tool;
9. View properties: Click to view the chemical structure properties on the drawing board;
10. Copy tool: Copy/paste the selected chemical structure;
11.ACS1996 drawing standard: Click to switch the "ACS1996 drawing standard" format
12. Cancellation: Cancel the previous operation;
13. Redo: Resume the previous step to cancel the operation;
14. Full Screen Tool: Click to enter or exit full screen.

Click on the [···] in the toolbar to see more tools.


15. Transfer IUPAC name to structure: Input IUPAC name can be automatically converted to the corresponding chemical structure;
16. Transfer structure to IUPAC name : Input chemical structure formula, converted into the corresponding IUPAC name by one button;
17. 3D mode translation: Click to convert the current chemical structure to 3D mode;
18. Grid line: Add grid line;
19. Share/Save button: Save the structure to your album in .Png format, or share the chemical structure with your friends;
20. Using Help: Click to view the using help;
21. Settings: Set up general functions of the drawing board;

Lower functional area – drawing tools area



(Slide the toolbar left and right to see more structure drawing tools)

The lower functional area is a collection of some common structural drawing tools -
Includes single bond, double bond, triple bond, arrow tool, solid wedge button, hollow wedge button, virtual wedge button, text tool, bold single button, long-chain tool, folded chain tool, cyclopropane template, cyclobutane template , cyclopentane template, cyclohexane template, cycloheptane template, cyclooctane template, cyclopentadiene ring template, benzene ring template, charge tool, flow chart tool, bracket tool.

Left functional area– elements selection area



The left side of the drawing board is a list of commonly used elements, which contains all the elements in the periodic table of elements.


Right functional area - common tool area



The right functional area includes 4 fast operation tools, as follows:-
1. Gesture drawing tool: Draw structure by gestures;
2.Group drawing tool: Click to add common group and support custom additions;
3. Beautify tool: Beautify structures intelligently, support repeatedly beautifying. Be careful with this move, you can use undo to recover your last move;
4. Move/Zoom tool: Two-finger move or zoom the drawing board;.
