Change the menu option Language to Chinese (Simplified), and then press OK to restart the software and change it to Chinese.
Step 2 Create a new model
Open the model from the File menu or create a new model.
3. Add a box-shaped integral variable.
(1) Click the var icon with an outline.
(2) Click the left mouse button in the blank (some versions need to double-click the left mouse button) and then enter the name of the variable to be created.
(3) After clicking the hand icon, move the mouse to the added variable area, click the left mouse button to pop up the property box, and adjust the surrounding shape, font size, color and text position of the variable.
Adjust the shape of the surrounding text outline.
Adjust the positional relationship between the text and the box.
Adjust the box color
Adjust whether to bring a background and the background color.
Select the text font, font size and color.
Select a property sheet with circular box type, red, blue background color, text in the box, black, timesnewroman font, size 12, black and variable results.
(4) Move the variable: click the variable with the left mouse button under the selected hand icon, select the variable and drag it to a satisfactory position.
4. Add comments.
(1) Click the comment icon with the left mouse button.
(2) Left-click outside the variable to pop up a dialog box, which is similar to the properties of the box variable. You can adjust the font color, type, size, outline type, color and background color of the annotation.
(3) Input the image in the hard disk as a comment, and click Enter to select the required file (only bmp bitmap is supported).
If a bmp file is selected and a hand icon is selected, click the image move position. If you want to resize the image, move the mouse cursor to the lower right corner of the image and a small circle will appear. Click and drag with the left mouse button to reduce and enlarge the image (note: you can guide the drawn brain map into bmp bitmap and then insert it as a comment variable).
(4) Input the built-in image: select the image, click the drop-down box next to the image, and select the required image file:
For example, after selecting a face, press OK to get the following annotation graphics:
Note: Insert text annotation, image annotation and bmp bitmap annotation on the hard disk respectively.
5. Establish relationships between variables, between variables and annotations, and between variables and annotation images.
(1) Select the arrow icon.
(2) Click the left key on the starting variable (variable), and then click the left key on the ending variable (comment), and the software will establish an association between these two variables.
(3) Drag the small circle on the arrow with the left key to adjust the bending degree of the arrow.
(4) Adjust the properties of the arrow. Move the mouse to the arrow. After the mouse becomes a hand, right click to pop up the property box. You can adjust the properties of the arrow, such as color, thickness and line type, and set the polarity marking function.
When you select a delay marker, the arrow marker changes to the following shape:
After selecting the polarity mark+the polarity mark outside the arrow position, the result is:
6. Delete variables
(1) After selecting the snake icon, click the variable to delete.
(2) Or select the hand icon 7, and move after selecting multiple variables or comments.
select
Method 1: After selecting the hand icon, hold down the shift key and click on the variables one by one to complete multi-selection.
Method 2: When choosing a hand type
(b) Move, that is, move the mouse to the selected area and press the left key to drag.
8. Copy a variable or variable group
Select a variable and press Ctrl+C to copy it, and then press Ctrl+V to paste it.
9. Solution of variable name.
Because vensim software can simulate running, it is not allowed to duplicate two variables to avoid confusion. However, the same words are often used when drawing the sky disk. You can use a variable name, a comment or both comments, and adjust them to the same shape as the variable by adjusting the properties of the comments.
Note: Multiple comments cannot form a loop (cross loop), otherwise an error will be reported. If you want to form a loop, there must be an integer variable (non-comment variable) in the loop. If it still can't be solved, add the order of numbers and codes to identify it.
10. Export the model file (sky map) as a picture.
(1) When the model occupies a small area, directly use the graphics cutting tool or the copy screen (prtsc button) to copy the graphics.
(2) when the model occupies a large area, use the file-> print pop-up dialog box on the menu bar:
Delete the title, select adobepdf as the printer (adobepro or related adobe printers must be installed on the computer), and click Settings to open the following dialog box. The blue box is used to estimate the selected paper type. If it is 100%, it means that the current paper can be printed completely.
Choose to print the page size of the whole model, such as a2 size, and output a pdf file.
Method 1: Open the pdf file and save it as a png picture (don't save it as. Jpg, which will cause confusion).
Method 2: Import pdf files with coreldraw software or photoshop software, and then export them as. Png files are exported by these softwares. Png files exported by these softwares are clearer.
1 1. How to improve the speed of drawing the sky disk?
(1) Draw some basic models, which can be drawn to three layers, and then save them as the basic template basic.mdl:
(2) Every time you create a new model, copy the elements of basic.mdl and quickly generate the corresponding complex diagram. If there are too many variables, quickly delete or add some variables to complete the frame diagram of the model:
(3) Finally, adjust the meaning of each variable and annotation to generate the whole sky disk.
12, Precautions for drawing ceiling.
(1) The sky disk should be rotated to the left from the starting point, and the rotation direction should be clockwise;
(2) The line in the sky disk cannot pass through the circle;
(3) The lines in the sky board should be smooth.
