When you open models, only contours are shown for some objects because of the following:
● You have disabled the Hide Non-Configured Objects check box.
● You are using a method filter that excludes objects. These objects are not removed from the models, but are only displayed in outline.
● The model has objects that are saved in groups for which you do not have read privileges.
● You have deactivated objects and/or connections using the Properties dialog boxes.
Rather than removing the prohibited objects entirely, only their outlines are displayed, so that the overall layout of the models is not damaged.
The assignment icon is not displayed even if models are assigned to unconfigured objects.
