This provides the facility to view previously created Parts stored in the default directory. If necessary, you can ask for a listing of all the DWG, DXF and VEC parts within the directory. As DWG parts are stored as AutoCAD's BLOCKS, they will be recalled very much the same way as AutoCAD's INSERT command.
The following will appear sequentially at the AutoCAD command prompts:
Select part format to view –
Dwg\Dxf\Vec <Vec> :
Part Name (? for list)<>:
Select part format to view – Dwg\Dxf\Vec <Vec>:
This is to prompt for the type of file format that you wish to view.
|•||“D” for Dwg|
|•||“X” for Dxf|
|•||“V” for Vec|
"Enter” for the default option, in this case the VEC file format.
Pick a point on the screen. The specified part will be displayed at the insertion point on the screen.
Part Name (? for list)<>:
This is to prompt for the name of the part, which you wish to review.
Enter the required part name.
Conversely, you can enter ?, which in turn will display a dialog box for you to select the part name.
When the nested layout is displayed in DWG format, you may encounter Parts overlapping , nested outside the stocks or parts not updated.
You can avert the problem by starting a new drawing and then view the nested results using ViewNEST. There is no need to re-nest.
The reason for this situation is as follows:- Each AutoNEST Part saved using SavePart will be stored as an AutoCAD block (.DWG) file besides .VEC and .DXF files. AutoCAD will still remember all the Blocks in its memory of the current drawing, regardless whether the Blocks were deleted or not.
This may pose a problem when Parts are edited and then re-saved. If you find that the nested results are not displaying the edited Parts in .DWG format, you can solve the problem by starting a NEW drawing and then ViewNEST.
In another situation, where the current drawing has different blocks of the SAME name, a copy of the Block in the current drawing will be inserted. This is all right if they are actually of the same geometry. Otherwise, it can be very confusing . (AutoNEST allows SAME names of Parts (Wblock) as long as they are in different folders)
This situation can be even more baffling if the existing Blocks have been erased from the current drawing yet AutoCAD remembers them in the drawing! This problem can be eliminated to a certain extent if unused blocks are purged from the drawing (AutoCAD PURGE command). This is the only way AutoCAD removes completely unused blocks. Starting a fresh new drawing will also help.
An experienced AutoCAD user will know how to avoid this pitfall.
