Validate Plant P&ID drawings

<?xml encoding=”UTF-8″>By Augusto Goncalves

Inside Plant P&ID we can Validate, via ribbon Home>Validate>Run Validation or right-click on a drawing and select “Validate”. More details here.

Using APIs there is a ValidationSingleton object that has a ValidateDrawings or ValidareProject method. After run this, the Errors property will contain a list of validation errors. Actually there is one class for each type, so you’ll need to cast or, like in the sample below, simply get the error name.

Important: this API method will *only* show the validation errors after you run it via built-in command.
