Enables you to manipulate all the layers and layer sets in the drawing (see Snap Modes and Layer Sets).
To create a new layer or layer set, select Create New in the Design Director toolbar or local menu.
When Layers or Layer Sets is selected in the upper pane of the Design Director, the lower pane has the following options:

Active: Sets the layer as active, or applies the layer set. Also indicates the layer for a selected object or tool.
Visible: Sets the layer visibility.
Lock: Use this switch to lock layers, which means the objects on them will be read-only. You can add objects to locked layers, but you cannot edit or delete objects.
Color: Sets the layer color.
Order: The order number of the layer.
Line Style: specifies the Line Style for the layer.
Pen Width: Specifies the Pen Width for the layer.
Print Style: Specifies the Print Style for the layer.

La yer Sets

A layer set is a group of layers, which can be handy if you want to set visibility, locking, and other parameters for multiple layers.

Select Layers in the upper pane of the Design Director.
On the lower pane, select the layers you want to include in the layer set.
Select Create Set in the Design Director toolbar or local menu.
Select Layer Sets in the upper pane in order to see the defined layer sets in the lower pane.
Select the properties (visibility, locking, etc.) of the layer set. When the layer set is made Active, these properties will be automatically applied to all layers in the set.

Available in DoubleCAD Pro only
Layer filters provide you with a powerful tool to organize your work, workflow and drawing. This feature also allows you to import DWG file that have embedded layer filters

Layer filters will organize you layer by a defined set of parameters.

Layer Templates

Layer templates allow you to create and save alternate configurations for layers.
Layer templates store how layers are setup, but do not store layers thenselves. Layer templates are saved in a *.lrs file which can be stored anywher in you system directory.
All layers which meet the parameters define by the filter will be grouped in the lower panel of the Design Director.

Note: The Show Filters and Group by Filters options must be turned on in the Design Director options for Filter groups to be displayed.

You can control all of the settings for the layers in the group. This means that if you change the color adjacent to the filter the color for all of its layer will be change to that color. If you change the visibility adjacent to the filter the visibility of all its layer will be changed to that visibility. If for any setting the layers contained in the filter have mixed settings for an option the filter will display a blank field or an ellipsis (...) for that setting. however you can still control the settings of the filtered layers.
To Change Layer Color Properties via the Filter

In the Design Director of a filtered drawing:
In the lower panel of the Design Director, hover the cursor over the color field adjacent to a filter.
Click on the color field.
When the Color dialog appears, select a color.The colors of all the filtered layers will be changed to the selected color.

To Create a Filter

Click the Create Layers Filter button in the toolbar of the Design Director.
When Prompted assign a name to the filter.
When the Filter Dialog appears, specify the parameters for the filter.
Click OK.

To Edit a Filters Parameters

Select the Filter in the top Panel of the Design Director.
Right click and Select Edit Filter Parameters..
When the Filter Dialog appears, reset the parameters for the filter.
Click OK.

Layer Filter Dialog

Available in DoubleCAD Pro only
The Layers filter dialog allows you to specify how your filters work.

The dialog is divided into three sections: Toolbar, Filter Parameters table, Filtering Results table.

Filter Toolbar

Parent Filter: Filter can have sub-filters. This setting allows you to specify a parent filter that will constrain the list of layer that the current filter will apply to.
Insert Wildcard: This button opens the Wildcard dialog which allow you to insert a wildcard into the currently selected field.
The dialog also defines how each of the wildcards function.

Duplicate Row: This button duplicates the currently selected row in the Filter Parameters table.
Delete Row: This button deletes the currently selected row in the Filter Parameters table.

Filter Parameters

The Filter Parameters table is where you specify how the filter will work by entering a set of parameters. Parameters are defined by values and wildcards. Each field in takes specific types of values.
Name: The Name field uses the name of layers to filter. Full names or parts of names can be combined with wildcards to specify what layers you want the filter to catch. The name field is the most versatile in regard to using wildcards.
Active: The Active field uses the Active status of layers to filter. It can take two values TRUE or FALSE. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~TRUE means = is not true. Since there can be only one Active layer at anytime, this option will make the filter dynamic as to what layers are captured.
Visible: The Visible field uses the Visible status of layers to filter. It can take two values TRUE or FALSE. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~TRUE = is not true.
Locked: The Locked field uses the Locked status of layers to filter. It can take two values TRUE or FALSE. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~TRUE = is not true.
Color: The Color field uses the Colors of layers to filter. It takes values which identify colors, either as RGB (True Color) values expressed as three numbers separated by commas, e.g. 10,20,30, or as Index colors expressed as a single number ranging from 1 to 255. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~10 = is not color 10. You cannot embed wildcard within the RGB value.
Line Style: The Line Style field uses the Line Styles of layers to filter. It takes values which are the names of Line Styles, such as CONTINUOUS or BORDER. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~BORDER = is not BORDER.
Pen Width: The Pen Width field uses the Pen Widths of layers to filter. It takes values which are the numeric values of the pen widths along with the units. For Example 0.5in or 33 mm. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~0.5in = is not 0.5in.
Order: The Order field uses the Order of layers to filter. It takes values which are the numeric values of the Order. For Example 1 or 55. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~10 = is not 10.
Print Style: The Print Style field uses the Print Styles of layers to filter. It takes values which are the names of Print Styles, such as 'Normal' or New Style. These can be combined with the NOT (~) wildcard to signify the opposite meaning. E.g. ~BORDER = is not BORDER.

Wildcards

Wildcards are special characters that are combined with other values to constrain a result. The wildcards that are supported by the filters are:
# (pound) Matches any single numeric digit. For example, if there are 1000 layers named 1 to 1000, you can build the filter to capture all of the layers from 500 to 599 by using 5##, or 550 to 559 by using 55#
@ (at) Matches any single alphabetic character. For example, if there four layers named EAST, WEST, BEST and TEST, you can build a filter to capture all four by using @@ST, or just the last three layer by using @EST
. (period) Matches any single non alphanumeric character. For example, if there were four layers named TOP_VIEW, TOP-VIEW, TOP VIEW and TOP:VIEW, you can build a filter to capture all four by using TOP.VIEW
* (asterisk) Matches any string (sequence of characters) and can be used anywhere in the search string, beginning, middle or end. For example, you have dozens of layers that include the term 1ST, you can capture all of them by using 1ST
? (question mark) Matches any single character; for example, ?BC matches ABC, 3BC, etc. As another example, if there four layers named EAST, 2EST, _EST and TEST, you can build a filter to capture all four by using ??ST, or just the last three layer by using ?EST
~ (tilde) Matches anything but the pattern, in other words it equals NOT. For example; ~AB*matches all strings that don't contain AB. As another example, you have dozens of layers that include the term 1ST, you can exclude them all from being captured by using ~*1ST
[ ] Matches any one of the characters enclosed; for example, [AB]C matches AC and BC. As another example, all of the layers begin with a single number, and you want to capture just those that begin with 5, 7 and 8. You can capture them by using [578]*
[~] Matches any character not enclosed; for example, [~AB]C matches XC but not AC. As another example, all of the layers begin with a single number, and you want to exclude from capture just those that begin with 5, 7 and 8. You can do this by using [~578]*
[-] Specifies a range for a single character; for example, [A-G]C matches AC, BC, and so on to GC, but not HC. As another example, all of the text layers have a format like TXT followed by a number followed by more characters e.g.TXT1TOP or TXT2BOTTOM. You want to capture any with the numbers 2, 3, 4, or 5. You can capture all of them using TXT[2-5]*
` (reverse quote) Reads the next character literally; for example, `~AB matches ~AB. This is especially useful if your layers have characters in their names that otherwise would be interpreted as wildcards.
Important Items to remember:
All items on the same row of a filter further refine (tighten) the results of the filter. For example, on one row, if under the Name field you have 1ST and in the Color field you have 55, the filter will capture only those items that have both 1ST and are Color 55
Items on separate rows expand the results of the filter. For example, if on one row in the Name field you have 1ST and on the next row in the Color field you have 55, the filter will capture all layers with 1ST and all layers with Color 55.
Sub filters are restricted to capturing only layers which are contained within their parent filters.

Filter Results

The Filtering Results table displays results of the filter as defined in the Filter Parameters table, this gives you a preview of how your filter will operate.
There are several functions which are available if you right click a field in the Filtering Results table.
Refine using this value: If this option is chosen the value in the field will be added to each row of the Filter Parameters table with content. This further restricts the results of the filter.
Refine excluding this value: If this option is chosen the value in the field will be added to each row of the Filter Parameters table with content with a ~ prepending the value. This further restricts the results of the filter.
Add all with this value: If this option is chosen the value in the field will be added to a new row of the Filter Parameters table. This expands the results of the filter.
Add all without this value: If this option is chosen the value in the field will be added to a new row of the Filter Parameters table with a ~ prepending the value. This expands the results of the filter.

Filters and XREFs

Available in DoubleCAD Pro only
When external references (XREFs) are add to a file all of the layers of the external referenced file are appended. The layers are listed under the XREF name as if the XREF was itself a filter. in add ti on the XREF is listed under the filters in the top panel of the Design Director. Within the Design Director lower panel you can treat the XREF as if it is a filter, including changing the values for the properties of all the layer s by making changes at the filter level. However, you cannot edit the parameters of the XREF as if it were a filter.
