Layer Keys
You can use a layer key to map specific entities within a block to a layer in the drawing into which the block is inserted.
For example, the millwork blocks depicted earlier (see “
Collecting Similar Blocks
” on page 2170) have the hatch entity
assigned to the layer “HATCH.” If the Recipe Specification (XML file) that references this block library has the attribute
“remapLayers” set to true, as shown below, then any layer that matches a layer key in the current drawing will be
replaced with the layer that is assigned to that layer key. In the case of a drawing using the standard AutoCAD Architecture
template file, in which the HATCH layer key is mapped to the AecDtl-Patt layer, any block library entities that were
assigned to the HATCH layer will end up on the AecDtl-Patt layer when inserted into the drawing.
<AcadBlockProps>
<BlockName dwgLib="dwgs/AecDtlLib_WoodMillwork.dwg"
remapLayers=”true”>AecDtl_millworkBlk1</BlockName>
<Scale>6.0</Scale>
</AcadBlockProps>
Removing Unnecessary Objects
Once you have ensured that a block library drawing conforms to all the previously explained guidelines, the final step
is to remove all unnecessary objects (unused layers, text styles, block definitions, and so on) by performing the following
procedure.
1
Use the ZOOM, EXTENTS command to display the extents of the current drawing.
2
Enter wblock (for Write Block).
3
In the Write Block dialog box, under Source, select Objects.
4
Under Base point, click the Pick point button, and then select a base point in the lower-left corner of the drawing
extents.
5
Under Objects, with Retain selected, click the Select Objects button, specify a crossing window over the entire
contents of the drawing, and then press
ENTER
.
6
Under Destination, enter the name of the drawing to be created (for example, enter the name of the current drawing
with a “2” appended), and click OK.
7
Close the drawing.
8
Using Windows Explorer, delete the original drawing.
9
Rename the new drawing by removing the “2” you appended.
The new drawing now contains only the entities you selected and any other entities directly or indirectly referenced
by the selected entities. In other words, the drawing contains only the absolute minimum set of objects that it
needs.
