How to create impossible box in APG21
So, this very quick and illustrative tutorial shows you how to create impossible box in Artplotty Grid 21 (or APG21). If you need to launch APG21, then click on the link below.
We believe APG21 is so easy to use that you just jump right in. Therefore, just follow along throughout the process. Overall, you will see how easy it is to create something in Artplotty.
The process
For the purpose of this lesson, we will use the line dataset for the entire creation of this box. If you make a mistake, then click Redraw after you make the correction. Thus, this will redraw the grid.
Follow the steps below to create this nice looking box.
Step 1 – Create outer box
Firstly, create an outer box. Generally, a rectangular contains four points. However, in APG21, we repeat the first and final point, since we are using a line to draw a box. See data below.
The data: (1,1), (1,19), (19,19), (19,1), (1,1)
Step 2 – Create center line
So, the center line is fairly simple. It just divides the box in half. See data below.
The data: (1,10), (19,10)
Step 3 – Create bottom vertical divider
Equally divide the bottom portion in half. See data below.
The data: (10,10), (10,19)
Step 4 – Bottom-left box
In like manner to the outer box, create a smaller box on the bottom left of the design.
The data: (3,12), (8,12), (8,17), (3,17), (3,12)
Step 5 – Bottom-right box
Also, create a box on the right side. Furthermore, make sure you align both boxes. See data below.
The data: (3,12), (8,12), (8,17), (3,17), (3,12)
Step 6 – Top-left box
Similarly to the bottom left box, create a top left box with the data below.
The data: (3,3), (3,8), (8,8), (8,3), (3,3)
Step 7 – Top-right box
Additionally, create a top-right box with the data below. We are getting close to the end. Exciting!
The data: (12,3), (12,8), (17,8), (17,3), (12,3)
Step 8 – Bottom horizontal connecting line
So, once you add the bottom horizontal connecting line, the piece is starting to look like something.
The data: (8,12), (10,12)
Step 9 – Bottom vertical connecting line
With the bottom vertical connecting line, it is starting to look like an entanglement, design-wise.
The data: (12,10), (12,12)
Step 10 – Top horizontal connecting line
In the same fashion, create a connecting line for the top two boxes, with the data below.
The data: (8,8), (12,8)
Step 11 – Top vertical connecting line
Finally, the top vertical connecting line completes the nice design. See the data below.
The data: (10,1), (10,8)
Success!
There you have it – The impossible box in APG21.
So, were you successful? If not, then give it another shot. By the way, we broke the steps down. But, you can skip steps and just certain points in one group.
We are not quite done. Perhaps, you want to create a transparent image or save the data for later.
Create transparent image
To create a transparent image, click Create PNG from the menu. As a result, you will get a beautiful image like the one shown below.
Save data
If you want to make changes to the impossible box in the future, then click Save Data from the menu.
Data to create impossible box
Below is all the data for the impossible box. You can copy it and put it in the upload box and click Upload. The impossible box will appear. Just make sure you select everything.
