For
assemblies opened in Large Design Review (LDR)
mode and for drawings opened in Detailing
mode, you can view the SOLIDWORKS files structure in the SOLIDWORKS PDM Task Pane (along
with icons) similar to the FeatureManager design tree.

For
the Detailing mode, the PDM Task Pane tree
displays child components only to the first level similar to the FeatureManager design
tree.
For the Large Design Review (LDR) mode, you can
perform SOLIDWORKS PDM operations such as Check
in and Check out on the
components from both the FeatureManager design tree and the Task Pane assembly tree.
