1. Modeller Region is not built-in into standard SMath Studio package. It should be installed using Extensions Manager (Tools > Plugins > Online Gallery).
   
   
   
2. Modeller Region available via Insert menu, so lets try to add it to the worksheet;
   
   
   
3. Modeller requires output variable to be set. Try to evaluate this variable after Region to see its value. 0 - means no data drawn.
   
   
   
4. Ok. Now we should specify objects can be used inside Modeller. This objects called Templates. Every Template is a row-vector with several parameters inside. All templates should be composed within single sys() function as shown below.
   
   
   
5. In the simplest layout you are able to set the name of Template and its path. Path is a matrix with two columns - pairs of coordinates of points. It is absolutely the same as supported by Plot Region.
   
   
   
6. Now we neeed to link Templates with a Modeller Region. It can be simply done with Context menu.
   
   
   
7. After it is done you will see a Shape appeared at right of Modeller and while this Shape is hovered you will see a hint with Shape's name.
   
   
   
8. That is all we need to start. Now you can drag'n'drop shapes from the palette at right to the Modeller canvas.
   
   
   
9. Check out output variable. Do you see how butifull it is? Indeed, it contains full description of Shapes drawn inside Modeller! Now we can do whatever we want with this data!
   - Column #1: Number of Template used for the Shape;
   - Column #2: X-coordinate of the Shape;
   - Column #3: Y-coordinate of the Shape;
   - Column #4: Width of the Shape;
   - Column #5: Height of the Shape;
   - Column #6: Determins whether Shape is active (focused);
   - Column #8: Unique id of the Shape;
   - Other columns I will discribe later.
   
   
   
10. We need more Templates!
    
    
    
11. As for me, I can play with it all day long
    
    
    
12. All Shapes are in vectors, so we can zoom in and out using mouse scroll.
    
    
    
13. By the way, to delete drawn Shape just focus it by mouse and press Del on keyboard. You can also update Shape properties by double click on it try it by yourself. For the start you can use example I created for this intro:
    modeller-demo.sm
    
    
14. Modeller Region is fully compatible with SMath Viewer, so you can create very powerfull applications now! For example there are 2 applications available via Extensions Manager.

That really seems to be a whole new space of opportunities. Will take a while to explore them.
One of them: Usage as multidimensional slider...

I cannot access the applications from the online gallery, neither in the installer version nor in the (otherwise reliable) portable one.

It seems very interesting, thank you Andrey

By the way, It crashes for me (Win7(x64))when choosing "Dependent layout" - see this video
Actually, have no idea what this "layout" means. When I choose it - there is "Syntax is incorrect" error or crash

I can imagine to create some applications for students with tasks about math, physics or anything else where students should set correct locations of some object to pass the test/exam. Note: that Print button is available in SMath Viewer, so the result can be sent to print out in seconds! Any ideas?

Best regards, Andrey Ivashov.

just copy and paste what I have below and include it in your template:

texty:mat("Text",mat("TESTR","Green",100,1,3),1,mat(20,40,2,1),mat(10,40,2,1),0,1,1,7)

SMath will crash. My guess would be that the code is trying to perform math operations on a string
