This means that a shape was required by a CAD file, but was not found in the library accessed by the build. This can result either from a lost shape or from a local copy of the user library being needed. Rerunning the Wizard and deselecting the user library specification will take care of the second case.
In Composer systems, this message can mean that multiple user macro libraries that had evolved under WinCAD were not consolidated when the project was imported into Composer. The information in the CLD files might be misleading or incorrect.
In any case, this report gives you a checklist of shapes that could get lost.
