Working with Drawings
Use
Just as with assemblies, drawings have their own document info record, which refers in its document structure to the relevant CAD model. As it is not initially possible to visualize all drawings in an assembly, or one of its component parts (for example, to check in or check out all of them at once, to make a version, to copy, or to replace), you can use a function in the SAP view to show or hide the drawings below each of the CAD models (see also:
Display Options).In the SAP view the system explodes the document structure upwards (where-used list); in the CAD view the CAD implementation scans the local computer to see which drawings are stored there, and then sends this information back to the CAD desktop, where, subject to CAD implementation, consistent naming is necessary.
If several CAD models are available for a drawing, then there needs to be one leading model. If a drawing has the same name as the leading model, then this drawing is visible; if it shares the name of another model, then it is not visible. This results in a difference between the SAP view and the CAD view.
If you are making a version of a model that is not the leading model for a drawing, then you can not make a version of the drawing, as it is not visible in the CAD view. You can, however, change this in the CAD worklist; as all parts and drawings are visible, you can make versions of them here.
If the drawing has several models, they are all displayed as "children" of the drawing; if the drawing has only one model, then the drawing is displayed without a structure.
If, during the first data transfer into the CAD desktop, a drawing has a different name to the leading model, the structures will be created on the SAP side during check-in, and the drawings will also be displayed in the SAP view, yet the drawings cannot be displayed automatically in the CAD view.
Only when the drawing is checked in, can the document structure for the drawing be updated. This has the implication that, when creating a version of a model, you must decide whether you really want a new version of the drawing.
The reason for this restriction is that there is no other opportunity, other than in a local where-used list, to find the relevant drawings for a 3D object. You cannot access the document structure in the CAD view, as no local changes (such as adding a part from a drawing) are saved here. The alternative - saving the local BOM after every change (online or offline) - is too time-consuming and prone to error.
If there are several drawings for parts or assemblies, you cannot display or check in into the CAD view; you can, however, find them in the working directory (type: "drw", not checked in), load them separately, and subsequently check them in.
