GENERATE ELEMENT SELECTION OPTION
Activating this button causes the elements you want to select by confirming with OK at the end of the process to be inserted. Specifically, they are transferred to layers, whose names are an amalgam of the setting of the insertion/removal layer prefixes and of the original name of the respective layer (example using insertion: Layer name "4203111" becomes "E2_4203111"). Any selection comprising elements already marked for insertion causes a warning message to be issued and said elements to be ignored. Activating the button COMPLETELY MARK GRAPHIC GROUPS after selecting part of a graphic group (for example, selecting only the signal mast) causes the whole graphic group to be processed (in the preceding example, that would include not only the signal mast, but the screen, all additional indicators and all attributes as well.) If an insertion/removal layer does not exist yet in a drawing, then the color of that layer is changed to the insertion/removal layer color active at the time. Meanwhile, the color of existing layers remains the same.
UNDO ELEMENT SELECTION
Activating this button causes the elements you want to select by confirming with OK at the end of the process, along with their visible attributes, to be transferred back to their original layers. What happens is the previous insertion and the layer name prefix identifying it are both undone (example using insertion: Layer name "E1_4203111" (once again) becomes "4203111"). In this case, the current insertion prefix has to be identical with the one active at the time the selection was generated. Any selection comprising elements that do not include the current prefix setting causes a warning message to be issued and said elements to be ignored. Following transfer of the layer names back to their original layers, any layers that no longer bound to objects are cleared.
Sometimes using the UNDO ELEMENT SELECTION may lead to the creation of previously undefined layers with correspondingly undefined colors. These layers are assigned the default color white. Presenting them properly with a different color (component color or red/yellow for insertion/removal) requires executing the SHOW CONSTRUCTION STATUSES function.
GENERATE DRAWING
This action is only relevant when taking approach # 2 (see RECOMMENDED PROCEDURE FOR WORKING WITH CONSTRUCTION STATUSES). When you choose the option GENERATE DRAWING in the "Insertion" menu, all elements marked for insertion are first transferred to their original layers and combined into a block before being taken out of the drawing and saved as a file. This new block is then automatically assigned to the drawing as an external reference. This assignment as external reference to the insertion file causes the layer names of the inserted elements to be changed to the point where the original layer names of the elements in the insertion file are preceded with the name of the insertion file, followed by the character "|" (example using insertion: If the original layer name was "4203111" and the name of the insertion drawing is INSERTION.DWG ->, the new layer name then becomes "INSERTION|4203111".)
More information on editing attributes is available under CONSTRUCTION STATUSES, EDITING ATTRIBUTES.
You can name an insertion/removal file by entering a name in the Edit box or by choosing the FILE... button. Analysis of the template described in the component file is initiated with generating a suggested name for the insertion/removal file.
UNDO DRAWING
This function makes it possible to take elements of an insertion/removal drawing already generated and assigned as external reference to a current drawing and to directly reinsert them in the drawing.
Once you have selected the external reference you want to edit from the pop-up list and finished editing it by confirming with OK, the program automatically performs the following actions:
•Releasing the selected external reference.
•Inserting the previously assigned reference drawing as a block.
•Disassembling and analyzing the block.
•Marking the inserted elements for insertion/removal.
