Multi-Threaded Retrieval
Saved documents are retrieved in multi-threaded mode. (Documents saved
in releases prior to SolidWorks 98 cannot be retrieved in multi-threaded
mode.)
When you retrieve a large part, drawing, or
assembly document, the document immediately displays in a view-only state
while the actual document and all its components are retrieved in the
background. During the view-only state, you can use all functions supported
in the SolidWorks Viewer (Zoom, Rotate, and so on), but you cannot switch
to another document or start to open another document. After the retrieval
is complete, SolidWorks changes to the normal edit state.
