Editing a Diagram

Process and Instrument Design

When you add a component to the side of a tank by selecting a line from the tank, the Vertex automatically adds constraints between the component/device and diagram line.

Geometric Constraints

  • For example, if the diagram does not have any constraints, the valve is not moved with the diagram line.
  • In some cases, the constraints may prevent an element from being moved. You can delete a constraint from a diagram line.
    1. Select the diagram line.
    2. Select the context-sensitive function Properties.
    3. Make the selection and click the Delete button.
    4. Click OK.
  • The constraints are not shown in the component's properties.

Stretch, Move

  • You can move elements in the diagram by dragging the handle (drag and drop).
