Warning As noted in the following sections, changes in data can lead to a variety of inconsistencies.

AutoPIPE will detect most inconsistencies, and will display warning or error messages.

However, AutoPIPE may not detect all of the possible inconsistencies. Users must take care in making changes, and must review the changes carefully, to insure that the modified geometry and properties are correct.

This section lists simple techniques for accomplishing the following:

Executing a command Selecting a component Inserting a component Modifying a component Deleting a component

Selecting a range of components (creating a selection set)

E

Commands can be executed in one of three ways:

Click on one of the buttons in a toolbar.

Select a command from the menu system

Key-in the command. The hotkey for each command is underlined in the menu system. As an example, to insert a bend, simply type I to go into insert mode, then B. The key-in command option requires memorization of certain hotkeys, but is an extremely efficient method of input.

S

P

Click on it with the mouse. By clicking on the outer edge of a component, the component turns red to indicate that it is selected. If it is a two-point component such as a valve or flexible joint, the red indicates that the beginning point and end point of a two-point component have been selected.

Graphically select a range of points (see following ‘Selecting a Range of Points’ section)

I

Position the cursor on the desired point by clicking on it, then click on one of the component buttons from the toolbar. To insert an intermediate run point, or multiple run points, click on the pipe run button.

Position the cursor on the insertion point, and then select the desired component from the Insert menu.

Users can graphically select a range to insert across ranges of points with one command (see

‘Selecting a Range’)

Place the cursor on the desired point, then use the keyboard equivalent menu commands to key-in the insertion

Position the cursor over the desired button, press and hold the left mouse button, then “drag” the button off the toolbar and “drop” it onto the desired point by releasing the mouse button. This is known as the “drag and drop” technique.

M

Use one of the techniques below to modify points or components.

Using the mouse, double click on the graphical representation of the component to open its associated dialog. Double click on a point to modify point offsets.

BASIC TASKS

Display the Input grids then select the appropriate grid tab and modify the value in the cell(s).

Double clicking a row in the Input grids will display the Modify dialog. Note: Ctrl+Enter, Copy/Paste or Copy Down can be used to change values over multiple cells.

D

Use one of the techniques below to delete existing points or components:

Select the unwanted component with the mouse then press the Delete key on the keyboard.

Select the unwanted component then press the Delete button on the command toolbar.

Position the cursor on one of the points, or select a range of points, then hold down the [Shift] and right-click the component to be deleted from the toolbar.

Graphically select a range, then select the corresponding component name from the Delete menu to delete across an entire range of points with one command (see Selecting a Range).

Select the unwanted component then select the Edit/Delete menu command.

Select it with the mouse or position the active point at that location, then select the corresponding component name from the Delete menu.

Select the appropriate row in the Input Grids and Press the Delete key on the keyboard. Note:

Multiple rows can be deleted at time.

Selection of ranges is a powerful tool within AutoPIPE that users should become familiar with. By graphically selecting ranges of points, users can insert, modify, or delete components, properties, loads, and other data across ranges of points with one command or graphically select points to be included in the output reports. Also, selection of ranges is required in order to graphically cut, copy, or paste.

There are several methods available to graphically select ranges of points. By using buttons or the Select menu or Input Grids, users can select by a number of different criteria such as by segment, point names, component type, pipe diameter and other parameters. In addition, users can create a mouse zoom box Window and click on the Select all points in Window button to select a range. Another common method used to select a range is to click on the first point in the range, press and hold the [Shift] key, then click on the last point in the range. The selection set will highlight in red. This is the same technique used to select ranges in Word, Excel, and other popular Windows programs.

To create a selection set that includes components that are not part of a contiguous run, use the [Ctrl]

key as follows: To add more components to this set, or delete points from this set press and hold the

BASIC TASKS

[Ctrl] key and select additional elements. The [Ctrl] selection method allows you to select a set of components that are not continuous. Alternatively, Select/Point enables buttons that can add or subtract from the selection set on a point by point basis.

The Select/Range command, another method of creating a selection set, allows the user to input

“From” and “To” points inside a dialog.

In any Input Grid Tab, select a group of rows or cells (same column) using [Ctrl] or [Shift] keys will highlight the selected points in red on the graphic. Note: The point symbol and names will be highlighted when selecting from the Points or Pres/Temp/PipeID Tabs. These two tabs enable selection of all points in the model. The Pres/Temp/PipeID Tab also provides a range selection up to and including the bend near or far points. All other grid Tabs will highlight the component symbol and the thermal anchor movements tab will highlight the anchor symbol on the graphic.
