KingDraw Tutorial- The Use of Common Chemical Bond Tools

Drawing any chemical structures, you cannot do without a variety of chemical bonds. KingDraw build a rich drawing element. How to use the various keys to draw the required structure? Today, we come to understand the drawing skills of common chemical bond tools firstly.

Common Chemical Bond

In the KingDraw APP, the commonly used structural drawing tools are focused on the lower functional area of ​​the drawing board, and the toolbar supports sliding and hiding from left to right.

Basic chemical bond such as single bond, double bond, triple bond, wedged bonds, and bold bond is there.

In addition to providing basic bond tools, KingDraw also provides multiple bonds tools such as double dashed bond, aromatic bond, double bond, etc. Press and hold the [Double Bonds] tool to view the selection.

Chemical Bond Tool Tips

Basic Drawing Method

Select the desired chemical bond type in the lower ribbon and click anywhere on the drawing board to display the corresponding chemical bond. If you still need to continue adding, just click at the end of the bond. Press and hold to rotate the bond angle.

Connecting Multiple Structure

If you need to connect two parts of the structure, just press and hold the bond you want to add and drag, the added bond will automatically extend, connecting the two parts structure.

In addition, you can also use the [Marquee Tool], click on one end of the button to drag and connect to the desired location.

When you draw a structure using various bonds, the system defaults to a simple hydrocarbon.

Change Bond Angle and Bond Length

After drawing various chemical bonds, if you need to change the bond angle and bond length, you can use the [Marquee Tool] to operate. After selecting the box selection tool, click on one end of the key to be adjusted to rotate or stretch.

Single and Double Bond Switching

Using a single-click on an existing single bond, you can switch a single button to a double button; if you click on an existing double button, you can switch the double button to a single button.

Change the Double Bond Display Style

Double-click on the existing double-key to switch between the two-button display mode. There are three display modes in total.

KingDraw tutorial 丨Grouping Tags to Manage Your Structure

If you are a person who pursue high efficiency and smooth operation

Then there is something you have hated for a long time.

---Find the desired file in a messy file heap

We introduced it to everyone how to quickly find structured files in the KingDraw App. Among them, the [Grouping Tags] function has arisen long discussion.

Many people are eager to know how to use this tool.

Today, we will give you a detailed introduction about How to use Grouping Tags?

What is the "Grouping Tags"

The Group Tags function in the KingDraw APP helps users to more carefully manage structured files, and can quickly query and locate the corresponding files by filtering labels.

How to manage Group Tags

Add group tags

After entering the “Management” interface, click “create” (no tags available) or “+” button at the top right to enter the Create Tags” interface.

Enter a tag name on the [Create ] interface, click [Add] to enter the Add Group Files interface. After the selection is completed, click the “Confirm” button in the upper right corner to return to the “Create” interface, and click the “Save” button in the upper right corner to complete the new tags operation.

• The addition of group files supports search and multiple selection.

• In the [Create ] interface, the tag name cannot be empty and cannot be duplicated with an existing tags.

• The group file can be empty.

Modify/delete group tags

In the "Management" interface. Click the taps for the content you want to modify and go to Edit Tags.

Click the "Add" button to enter the "Add Group Files" interface, you can add a group file.

Click the "Delete" button to change the group file to a deleting state. After deleting the group file, click the "Finish" button to save the delete operation.

After the modification is completed, click the “Save” button in the upper right corner of “Edit ” to complete the tag modification.

• In the New Tag interface, the tag name cannot be empty and cannot be duplicated with an existing tag.

KingDraw Tutorial丨How to use the color tool?

KingDraw Tutorial丨How to use the color tool?

Today, we will introduce how to use the color tools in KingDraw.

We received some questions about: How to change the color of the elements? How to change the color of the structure? Why it is not working when clicking the color tool?

In fact, the [color tool] is very simple to use. Combined with the [Marquee] tool, it is very easy to change color anywhere you want. Let's look at the specific operation.

Introduction of Color Tools

The color tool is in the upper part of the KingDraw drawing board. Long press on the Color Tool. The KingDraw APP gives you 7 default colors and supports custom color settings.

How to Change Color

Let's take the following structure as an example to see how it worked. First, use the Marquee tool to select the structure you want to change color.When the structure is hard to select, we can press and hold the lasso tool. Once selected, long press "Color Tools", click on the desired color, then the selected part will change. And it has also become the default color of our drawing board. The next time you use the same color, just pick the section and click the color tool , then complete the color change.

If you need to use a different color, you will need to long press and choose again.

Color tools can not only change the color of a structure, it can also change elements, text, arrows, parentheses, flowcharts, etc., as long as they are selected.

How to Customize Color

Custom colors can select colors manually. Or you can set RGB directly here to select the colors.

Today’s function introduction is all above. If you have more questions, please feel free to leave us a message.

As a chemist, drawing a chemical structure is almost a daily must. Over time, a large number of structured files will be stored. Sometimes, you may spend most of the day, just looking for a file, which is quite burden when you are in a hurry.

How to easily find the file you want in the KingDraw App? Come on and follow us!

You can quickly query and navigate to saved files by clicking the "Search" button above the main interface. We have provided you with the following three ways to search for structure ：

01 Search by file name

Click the "Search" button to enter the "Search" interface. After entering the file name in the search box, click the "confirm" button. The structure file that meets the search criteria will be displayed in the list box.

02 Search by substructure itself

Click the "Tap To Draw" button to enter the drawing board and draw the structure you need. Click the "Done" button in the upper left corner and the system will display the file containing the drawing structure in the list box.

In the " Draw Board" interface, click the "Historical " button to directly find the structure that has been searched before.

03 Search by group label

Click the "Tags" button to enter the "Add Filter Tags" interface. In "More Tags", select the tag you want to use as a filter and place it in the "Selected Tags". Click the "Done" button and the selected grouped file will be displayed in the list box.

In the "Add Filter Label" interface, click the label in "More Labels", you can put the label into the "Selected Label", click the label in "Selected Label", you can put the label back to "More Labels" in. The KingDraw App allows multiple tags to be selected at the same time, and the system takes the union of multiple tags as a filter.
