Solids Builder - While

While - creates a loop where the condition is evaluated before the first execution of a sequence of activities:

A WHILE activity requires an expression to evaluate to true or false, in order to decide to execute the body. This expression must obey the syntax of programs written in Visual Basic, such as:

• A > B - assuming A and B are numbers for example
• P1.X = P2.X - assuming that P1 and P2 are points, X would be the abscissa
• A = "1" - assuming A is a string

If you need to include more than one activity within the WHILE body, use FLOWCHART or SEQUENCE

From the activity inserted inside the body, proceed as if you were in the main flow, clicking the FLOWCHART so that it expands:
