Select Existing Objects

You must select the objects before you can edit them.

When you create a selection, temporarily isolate some objects of the document so that you can edit them without affecting the rest of the document. You can move a selection, copy it, cut it, save it as a macro, and apply special effects to it.

Objects can be selected irrespective of their type.

Select a single object

Place the mouse on the drawing over the object. Click the left mouse button. The object selected becomes marked by little squares. Components, OLE-objects, texts, value crosses and most graphical objects will be marked by eight little squares arranged in a form of a square. A selected pipe will be marked by little squares at each ending and bending. The colour of a marking square is normally black. If it is displayed on a coloured background, it is displayed in the inverse background colour.

Other objects already selected will become de-selected.

Though, if you push the CTRL key and click with the left mouse button on another object, it will be added to the selection. If you click on an already selected object while pressing CTRL, it will be removed from the selection.

If you are not sure, whether an object is selected or not, zoom in or out, or change the visible area of the drawing.

Select several objects

Place the mouse in the drawing at a corner of the rectangular area you want to select.
Press and hold down the left mouse button and drag the mouse until the selection is the size you want. As the mouse moves, a line appears to indicate the border of the selection.
Release the mouse button. All objects present within the selection get marked by eight little black squares.

If you draw the frame from left to the right, all objects are selected that are completely within the frame.

If you draw the frame from right to left, all objects are selected that are within the frame or touched by the frame. For instance, all incoming lines will be included to the selection in this case.

You can also select several objects by clicking on the objects one by one and keeping the Shift-key or the Ctrl-key pressed.

To remove the objects from a selection (so that they are de-selected), you can click the object again while keeping the Ctrl-key pressed; a double-click is needed when you keep the Shift-key pressed.

Select objects by name and type

If you know the name of an object you can select it in the ”Select Object” window. This window can be activated via:

Click the command ”EditàSelectàObjects” from the menu bar or
Position the mouse pointer in a blank area of the drawing and click the right mouse button to select the option ”SelectàObjects” from the context-menu displayed, or
Click on the Binocular-icon in the tool bar.

This opens the Find tool.

Object selection - subset as filter

You can also define a subset of object types from which you then select objects.

The combo box to the right of the mouse pointer symbol (rectangular selection) and the lasso symbol (freehand selection) serves this purpose. In this combo box you have the possibility to tick off the object types you do not want to select. If you then select an area of the model with the rectangular or the freehand selection, only objects of the object types that are checked in the filter are selected.

The (additional) selection or deselection of individual other objects with a single mouse click is still possible, regardless of whether their object type is checked in the filter or not.

The selection of the subset is cancelled when you press the escape key.

Select all objects

Select the command ”EditàSelect All” from the menu bar or press ”Ctrl-A” on the keyboard.

Examples

One object selected:

The only object selected is the generator. This can be seen from the eight little marking black squares arranged in a square round the selected object.

Several objects selected:

Generator
Value field (value cross respectively)
Electric pipeline
Mechanical Shaft
Turbine
Two steam pipes
Start value

All these objects are highlighted by little black marking squares.

Each component is marked by eight squares.

The endings and all section points of the selected pipelines are marked by squares.

Change selection of objects

To add objects to a selection, press the shift key and select the objects as described above.

To remove an object from a selection, position the mouse over the selected object, press the shift key, and double-click the left mouse button.

To de-select all selected objects, click the left mouse button with the mouse pointer placed outside of any object selected (without the shift key pressed).

You can have select several objects of the same or different documents within different windows at the same time.
