Preloading diagrams
The preload diagram functionality improves access to frequently opened diagrams by adding them to a preload list (the Preload pane). When both the Enable background diagram preload option and the Automatically add diagrams to preload options are enabled (in the Tool Options dialog), Modeler automatically adds diagrams that you open to the preload list, which makes them available more quickly the next time you use them.
Enabling the preload diagram functionality
To enable the preloading diagram functionality
1. Click > , the Tool Options dialog opens.
2. Click the Diagrams. entry.
3. Select the Enable background diagram preload option (this option is enabled by default).
4. Select the Automatically add diagrams to preload option. When you enable this option, PTC Modeler automatically adds all the diagrams that you open to the preload list.
5. You can also select the threshold at which Modeler stops adding diagrams automatically to the preload when you open them, the default is 20 diagrams. You can modify this threshold by changing the Preload list size value. If this limit is reached, PTC Modeler notifies you in the Preload pane. Note that this limit does not apply when you add diagrams manually to the preload list.
6. Click OK.
This preload diagram functionality is now enabled.
Considerations for using the preloading diagrams functionality
• If the Automatically add diagrams to preload option is disabled, the diagrams will not be added to the list automatically, but you can use the Add to preload context menu option to manually add diagrams to the list. Right-click on the diagram that you want to add and select Add to preload.
• To remove any diagram from the preload list, right-click the diagram (from the Package browser or from the Preload pane) and select Remove from preload.
• When you open any diagram that you have removed from the preload list, the diagram is added back if the Automatically add diagrams to preload option is selected and the list has not reached its limit.
• If the Enable background diagram preload option is disabled, you can still add diagrams to the list manually, but the diagrams will not preload.
• The Preload Status pane indicates what diagrams are added or removed to / from the preload list, whether all preloads have been completed or whether the maximum number of preload objects has been reached.
