Use object properties
or object types to include objects in a selection set, or to exclude
them.
To
quickly define a selection set based on specified filtering criteria,
use
- Quick
Select (QSELECT) from the Properties
palette to filter selection sets by property (such as color) and
by object type
- Object Selection Filters dialog box (FILTER) to filter selection
sets by property and by object type
- Select Similar (SELECTSIMILAR) to select similar
objects of the same type based on specified matching properties
If you added a feature classification to an
object using Autodesk or a third-party application, you can select
objects by classification property. With object selection filters,
you can name and save filters for future use.
With
Quick Select or object selection filters, to filter your selection
set based on color, linetype, or lineweight, consider whether these
properties are set to BYLAYER for any objects in your drawing. For
example, an object may appear red because its color is set to BYLAYER
and the layer color is red.
By default, objects of
the same type are considered similar if they are on the same layer,
and, for blocks and other referenced objects, have the same name.
Subobjects are only considered at the object level. For example,
when a mesh vertex is selected, SELECTSIMILAR selects other mesh
objects, not just the mesh vertices.
NoteIf an application
such as AutoCAD® Map 3D was used to add a
feature classification to an object, and the associated classification
(XML) file is present, you can select objects by classification
property. Specifically, you can select a classification in the Object
Type box and a property in the Properties box.
To create a selection set
using Quick Select
- In the Quick Select dialog box, under
Apply To, select Entire Drawing.
- Under Object Type, select Multiple.
- Under Properties, select Color.
- Under Operator, select Equals.
- Under Value, specify the color.
- Under How to Apply, select Include in
New Selection Set.
- Click OK.
To exclude objects from
the selection set
You can exclude objects from the current selection
set by using the Exclude from New Selection Set option. In the following
example, you exclude all circles with a radius greater than 1 from
a set of objects already selected.
- Select several objects.
- In the Quick Select dialog box, under
Apply To, select Current Selection.
- Under Object Type, select Circle.
- Under Properties, select Radius.
- Under Operator, select Greater Than.
- Under Value, enter 1.
- Under How to Apply, select Exclude from
New Selection Set.
- Click OK.
All circles with a radius greater than 1 are
removed from the selection set.
To append objects to the
selection set
You can use Quick Select to append objects to
a current selection set. In the following example, you keep the
current selection set and append all objects in the drawing that
contain hyperlinks whose names begin with bld1_.
- In the Quick Select dialog box, select
Append to Current Selection Set.
- In the Object Type box, select Multiple.
- Under Properties, select Hyperlink.
- Under Operator, select Wildcard Match.
- Under Value, enter bld1_*.
- Under How to Apply, select Include in
New Selection Set.
- Click OK.
To name and save a filtered
list
- At the Command prompt, enter filter.
- In the Object Selection Filters dialog
box, under Select Filter, select a filter such as Line.
- Click Add to List.
- Under Save As, enter a filter name such
as Linefilter.
- Click Save As.
- Click Apply.
The filter is applied so you can select, in
this case, only lines in the drawing. If you select objects with
a selection, the filter is applied to all objects in the selection
area.
To use a named filter
- At the Select Object prompt, enter 'filter.
(The apostrophe makes it a transparent command.)
- In the Object Selection Filters dialog
box, under Select Filter, select the filter you want to use. Click
Apply.
- Use a crossing window to specify objects
for selection.
Only the objects selected
by the crossing window that match the filter criteria are selected.
To create a selection set
of similar objects
- Enter selectsimilar.
- Enter se (settings).
- In the Select Similar Settings dialog
box, select the properties that must match for objects of the same
type to be considered similar.
If no properties are
selected, objects of the same type are selected.
- Click OK.
- Select object(s) as the selection criteria.
- Press Enter to select similar objects.
