Primary / Secondary Shapes
: Creating Secondary Shapes by Changing Name
Creating Secondary Shapes by Changing Name
When a shape of one of the above listed types is dropped on to the drawing, this shape will automatically be considered a Primary shape. You can create a secondary shape representation of the database element by changing its name in the
Shape Data
window. This behaviour depends on the default settings, please refer to section
Behaviour of Primary/Secondary Shapes
.
Because of the database structure, inline elements are created differently from non-inline elements.
Create secondary shape by name change of an inline shape:
1.
Drag and drop a symbol of a piping or valve inline component from a stencil onto the drawing canvas. The symbol will not be defined.
2.
Change the name of the undefined and unconnected symbol to the name of an existing item of the same type.
3.
The application prompts the user with a dialog box informing that the item already exists and asks if a secondary shape should be created:
Click
Yes
and the shape will then refer to the existing item in the database, the name should be manually entered, and it will be made into a secondary shape.
Create secondary shape by name change of an non-inline shape:
The user can create a secondary non-inline element using the same technique as for inline elements. However, a non-inline element has to be defined and may be connected to other elements.
If the user decides to create a secondary shape representation, he may be asked for confirmation of deletion from the database of the original item created when the shape was dropped (depending on the setting). Please see
Behaviour of Primary/Secondary Shapes
.
If the original database item contains some subordinate Electrical Connection Elements or Nozzles, a dialog is shown asking if these should be copied into the existing item is having the new name entered manually.
When the element is connected to other items, the system behaves differently depending on the type of connected element. Please refer to the table below for more information.
Note: (EXISTING_ITEM" - element that already exist in DB, "CURRENT_ITEM" - element where name is changed)
“The already existing item in the database”
“The shape on the drawing that is being modified”
Situation on drawing
Description
EXISTING_ITEM - The already existing item in the database.
CURRENT_ITEM - The shape on the drawing that is being modified.
Behaviour
1.
The Equipment contains an electrical connection. The Electrical connection is connected to a cable. The EQUIPMENT name is changed manually.
In a dialog the user is asked if the connected electrical connection should be moved to the already existing item in the database. The answer is NO.
(If the answer is YES the system moves the elconns to the destination element without disconnecting cables. The same behaviour is for nozzles)
The following behaviour occurs:
1.
The electrical connection will be undefined.
2.
The cable will be disconnected from the electrical connection on the drawing.
3.
The cable will be disconnected in the database.
The Equipment contains an electrical connection and the Electrical connection is connected to a cable. The Electrical connection name is changed manually.
The following behaviour occurs:
1.
A change to secondary will be possible only if the already existing item in the database has the same owner as the shape on the drawing that is being modified.
2.
Cable will be disconnected on drawing.
3.
Cable will be disconnected in DB.
The Equipment contains a electrical connection. The Electrical connection is connected to a cable. The cable name is changed manually.
1.
The cable will be disconnected on the drawing.
2.
The cable will be disconnected in the database.
The Equipment is connected to a cable. The Equipment name is changed manually.
1.
The cable will be disconnected on the drawing.
2.
The Cable will be disconnected in the database.
The Equipment is connected to a cable. The cable name is changed manually.
1.
The Cable will be disconnected on the drawing.
2.
The Cable will be disconnected in the database.
The Equipment contains a nozzle. The nozzle is connected to a branch. The Equipment name is changed manually.
In a dialog the user is asked if the connected nozzles should be moved to the already existing item in the database. The answer is NO.
1.
The Nozzle shape will be undefined.
2.
The Branch will be disconnected on the drawing.
3.
The Branch will be disconnected in the database (the database connection will not be changed if the branch is represented by the secondary shape).
The Equipment contains a nozzle. The nozzle is connected to a branch. The Nozzle name is changed manually.
1.
The Nozzle element will be transformed to secondary only if the already existing item in the database has the same owner as the shape on the drawing that is being modified.
2.
The branch will be disconnected on the drawing.
3.
The Branch will be disconnected in the database (the database connection will not be changed if the branch is represented by secondary shape).
The Equipment is connected to a branch. The Equipment name is changed manually.
1.
The Branch will be disconnected on the drawing.
2.
The Branch will be disconnected in the database (the database connection will not be changed if the branch is represented by secondary shape).
The Actuator is connected to an inline element. The Actuator name is changed manually.
1.
The shape on the drawing that is being modified removes connection to valve.
2.
The Actuator shape will be disconnected on the drawing.
The Actuator is connected to an inline element by a relationship shape. The Actuator name is changed manually.
1.
The shape on the drawing that is being modified removes connection to valve.
2.
The Relationship shape will be disconnected from the Actuator and will be undefined.
The system also enforces some restrictions on secondary shape handling for hierarchically subordinate items such as sub-equipment and electrical connection elements. For example, it is not allowed to have secondary electrical connection elements referring to a DB item owned by a different equipment item than the one that the electrical connection element is connected to on the current drawing. This is described in more detail under
Behaviour of Primary/Secondary Shapes
