Walla is an efficient and reliable piece of software developed in order to provide you with an easy means of creating creating shapes, such as circles, rectangles or irregular polygons, by making use of Excel data sheets.
The program itself is not difficult to understand or use, but for every shape you want to create, you will require an XLX or XLSX document containing the values which Walla will use in rendering the rectangle or circle you want to create.
For each project, you need to write yourself the Excel file yourself, as Walla does not do that for you. If you do not have much knowledge of the subject, the application offers you several online resources and examples that you can use to figure out how to create your XLS files, but you will need Microsoft Excel to do that.
When you load your file into Walla, it will not display anything initially, as you need to select the shape you wanted to create and enter its 'Cell Range', so the utility can retrieve the data and display the geometrical figure in the main window of. The 'Zoom In / Out' function enables you to look at the design more closely.
Using the 'Manage Shapes' component, Walla allows you to modify the properties of certain shapes or delete them entirely from your file. With the 'Section Property' tool, you can view the parameters of the created rectangle or circle in detail.
While Walla only lets you to save the file to STC format, it offers you the possibility of copying it to clipboard so you can paste it in another compatible applications, fur further work. At the moment it only provides support for a limited amount of shapes, but it shows a lot of promise for future enhancements.
To conclude, Walla is an interesting and useful program whose main purpose is to help you create geometrical shapes (circles, rectangles, regular and irregular polygons) of any color you want using Excel data files.
