The Hatch dialog box appears to select the hatch pattern and specify options:

Options:

Type and pattern

Type:	Drop-down list to select the type of hatch pattern: The following types are available: Predefined User defined Custom
Pattern:	Drop-down list to select the available predefined patterns. The Pattern option is available only if you set the Type to Predefined. This button opens the Hatch pattern dialog box. The dialog box contains the tabs: ANSI – the hatch patterns of the ANSI standard; ISO – the hatch patterns of the ISO standard; Other Predefined – the hatch patterns that are not related to the ANSI and ISO standards; Custom – the list and patterns of the custom file format *.pat.
Swatch:	Displays a preview of the selected pattern. Click the swatch to display the Hatch pattern dialog box.
Custom pattern:	Drop-down list to display the available custom patterns. The Custom pattern option is only available for Custom type of hatch pattern. If you select the Custom option in the drop-down Type list, the Hatch Pattern dialog box opens on the Custom tab: The available custom hatch patterns display in the left part of tab. The selected pattern displays in the right part: The custom hatch pattern (file with *.pat extension) are placed in the folder: C:\ProgramData \Nanosoft AS\nanoCAD Int 23.0\SHX. This button opens the Hatch pattern dialog box.

Angle and scale

Hatch origin
Sets the start point to create the hatch. Some hatches, such as brick patterns, need to be aligned with a point on the hatch boundary.
By default, all hatch origins correspond to the current UCS origin.

Use current origin	Turns on the mode of origin setting stored in the HPORIGINMODE system variable. The origin is set to 0,0 by default.
Specified origin	Specifies a new hatch origin.
Click to set new origin	Specifies the new hatch origin point on the screen using the cursor.
Default boundary extents	Turns on/off the mode for calculation of a new origin based on the rectangular extents of the boundary for the hatch. From the drop-down list the following options are available: Bottom left Bottom right Top right Top left Center The icon displays the current position of the origin point:
Store as default origin	Turns on/off the mode for saving the value of the new hatch origin in the HPORIGIN system variable.

Boundaries

	Add: Pick points	Determines a boundary from the existing objects that form an enclosed area around the specified point. The dialog box closes temporarily and you are prompted to pick a point.
	Add: Select objects	Determines a boundary from selected objects that form an enclosed area. The dialog box closes temporarily and you are prompted to select objects.
	Remove boundaries	Removes from the boundary definition any of the objects that were added previously. This option is unavailable if you have not specified points or not selected objects.
	Recreate boundary	Creates a polyline or region around the selected hatch and optionally associates the hatch object with it. This option is available when you edit the hatch.
	View selection	Temporarily closes the Hatch dialog box and displays the currently defined boundaries with the current hatch settings. This option is unavailable if you have not specified points or not selected objects.

Options

Associative	Turns the associative hatch mode on/off.
Create separate hatches	Turns on/off the mode for changing a single hatch object that has several separate boundaries into individual hatch objects. When this mode is turned on, the hatch will be created for each counter, which representing a separate object.
Draw order:	Drop-down list to assign the draw order to a hatch or fill. From the drop-down list the following options are available: Do not assign Send to back Bring to front Send behind boundary Bring in front of boundary
Inherit Properties	Temporarily closes the Hatch dialog box to specify boundaries using the hatch properties of a selected hatch object.
	Temporarily closes the Hatch dialog box and displays the currently defined boundaries with the current hatch settings. Press ESC to return to the dialog box.
	Expands the Hatch dialog box to display more options. The More Options section of the Hatch dialog box:

Islands

Island detection	Turns on/off the mode to detect internal closed boundaries (islands).
Island display style	Selects the island display style.
Normal	Hatches inward from the outer boundary. If the hatch encounters an internal island, it turns off hatching until it encounters another island within the island.
Outer	Hatches inward from the outer boundary. Hatch turns hatching off if it encounters an internal island. This option hatches only the outermost level of the structure and leaves the internal structure blank.
Ignore	Ignores all internal objects and hatches through them.

Boundary retention

Boundary set

Defines the set of objects analyzed when defining a boundary from a specified point. The selected boundary set has no effect when you use Select Objects to define a boundary. From the drop-down list the following object sets are available:

• Current viewport – Defines the boundary set from everything within the current viewport.
• Existing set – Defines the boundary set from the objects that you selected with New.
  

New Sets the maximum size of gaps that can be ignored when objects are used as a hatch boundary.

Gap tolerance

Inherit options When you use Inherit Properties to create a hatch, these settings control the location of the hatch origin.

To create hatch:

1. In the Hatch dialog box select the required hatch pattern from the drop-down Pattern list or in the Hatch pattern dialog box opened after you click icon. The graphic structure of the selected pattern will be displayed in the Swatch field.
2. Set the required hatch options in the dialog box.
3. Click Add: Pick points icon and specify points inside the areas that need to be hatched. Or click Add: Select objects icon and select objects that form an enclosed area. The selected boundaries for the hatch are highlighted by a blue solid line when you pick a point inside the area and a white dotted line when you select objects. If the results of highlighting are not satisfactory for any reason, press ESC or click Cancel to cancel the context menu for the selected boundaries and return to the Hatch dialog box to reset the selection. The Preview and OK buttons in the opened dialog box will be blocked.
4. If the highlighted contour is satisfactory, press ENTER or click the Enter command in the context menu of the Hatch dialog box.
5. To preview the hatch result, click To finish the command without previewing, click OK.

When you preview the hatch result:
1. If the preview of the hatch is satisfactory, click Accept in the command line or click Enter or Accept in the context menu to finish the command. Pressing ENTER also finishes the command.
2. If the preview is not satisfactory, select Reject in the command line or click Cancel or Reject in the context menu to return to the dialog box and change the hatch options. Pressing ESC also returns to the dialog box.

To create the hatch using the inherited properties of a selected hatch:

1. Click the Inherit properties icon. The Hatch dialog box closes temporarily, to select the prototype hatch.
2. Select the hatch object whose properties you want the hatch to inherit. The Preview and OK buttons in the opened dialog box will be blocked.
3. After selection, you can right-click in the drawing area and use the options on the context menu to switch between the Pick Internal Point and Select Objects options to create boundaries.
4. The order of the rest of the actions corresponds to the order of actions performed when you create a hatch.
