-Hatch

Current hatch pattern: ANSI31

Reports the name of the current hatch pattern; you can change the pattern name with the Properties option.

Specify internal point

Pick a point inside a closed area; BricsCAD creates an invisible boundary, and then hatches the area. You can pick more than one area to hatch at a time.

Properties

Enter a pattern name

Specifies the name of the hatch pattern.

 ? to list patterns

Lists the names of all patterns; reminds you of their names.

Press F2 to see the list in the prompt history window.

Solid

Specifies a solid filled hatch.

User defined

Allows you to define simple hatch patterns based on angle, scale, and crosshatching.

Proceed

Skips the next two prompts, and returns to the original prompt.

Scale for pattern

Specifies the scale factor of the hatch pattern.

The scale factor is usually the same as that of text and linetypes.

Angle for pattern

Specifies the angle at which the pattern is drawn.

User Defined

Proceed

Skips the following prompts, and returns to the original prompt.

Space between standard pattern lines

Specifies the distance between hatch lines.

Angle for lines

Specifies the angle at which the pattern is drawn.

Cross-hatch area?

Applies the pattern a second time at 90 degrees to the first.

Select

Prompts you to select the entities making up the boundary:

Select entities - select one or more entities.

Select entities - press Enter to return to original prompt.

Remove

Allows to remove boundary entities.

Prompts you to select island (interior) entities, which will be hatched through.

Advanced

Prompts you:

Enter an option [Boundary set/Retain boundary/Island detection/Specify style/Set associativity(A)/Boundary tolerance(T)/Seperate hatches(H)]:

Boundary set

Specifies the entities to consider for creating boundaries:

Specify candidate set for boundary [New selection/All objects(E)]<Everything>: - enter Y or N.

• Everything - selects all entities in the current viewport.

• New - prompts you to select entities.

Retain boundary

Determines whether the temporary boundary created by BricsCAD is retained after the command ends:

Retain derived boundaries? [Yes-Retain boundariess(Y)/No-Discard boundary(N)]<No>: - enter Y or N.

• Yes - boundary is kept in the drawing.

• No - boundary is erased.

Island detection

Toggles whether islands are hatched over or not:

Do you want island detection? [Yes-Detect islands(Y)/No-Set ray casting(N)]<Yes>: - enter Y or N.

• Yes - islands (interior boundaries) are not hatched.

• No - islands are hatched over.

Style

Specifies how islands are treated:

Enter hatching style: [Nested/Outer/Ignore]<Nested>: - enter N, O, or I.

• Nested - alternating islands are hatched, beginning with the outermost one.

• Outer - only the outermost region is hatched; interior islands are not hatched.

• Ignore - islands are ignored and hatched over.

Associativity

Toggles whether hatches are associative:

Associativity hatch? [Yes-Associative hatch(Y)/No-Nonassociative hatch(N)]<Yes>: - enter Y or N.

• Yes - hatches are associative; when their boundary changes, they automatically update.

• No - hatches are not associative; when the boundary changes, the hatch keeps its original shape.

Tolerance

Specifies the largest gap that BricsCAD will close when hatching open areas:

Specify a boundary gap tolerance value <0>: - enter a value.

 Separate Hatches

Create separate hatches? [Yes/No-Do not separate(No)]:<No>: - enter Y or N.

• Yes - creates seperate hatches if the hatch is composed of multiple closed boundaries

• No - creates a single hatch entity.

Draw order

Specifies whether the hatch pattern appears visually above or below overlapping entities.

Prompts you:

Enter an option [None/Send to back(B)/Send to front(F)/Send behind boundary(H)/Bring in front of boundary(D)]:  - enter an option.

• None - ignores draw order.

• send to Back - places the hatch pattern behind (below) other entities; this prevents the hatch from obscuring other entities.

• bring to Front - places the pattern in front (on top) of other entities.

• send beHind boundary - places the pattern behind its boundary; this makes it easier to select the boundary.

• bring in front of bounDary - places the pattern in front of its boundary.

Origin

Prompts for a new hatch origin point:

New value for the hatch origin <0.0000,0.0000>: - enter x,y coordinates, or pick a point in the drawing.

Use entity snaps to pick the origin accurately.

Annotative

Sets the Annotative property of the hatches.

Applies the current annotative scale (see the CANNOSCALE system variable).

Prompts you:

Create annotative hatch [Yes/No] <No> - type Y or N.

• Yes - creates annotative hatches.

• No - creates non-annotative hatches

Layer

Allows to create the hatch on a specified layer, rather than on the current layer.

Prompts you:

Specify layer or . for use current <.>:

Type the name of the layer you want to create the hatch entity on or press Enter to create the hatch on the current layer.

Transparency

Allows to set the Transparency property of the hatch.

Prompts you:

Specify transparency [0/90/ByLayer(L)/ByBlock(B)/. for use current(.)] <Use current>: - enter an option.

• Use current - apply the current transparency value as defined by the CETRANSPARENCY system variable.

• Specify transparency [0,90] - type a value or use the slider to set a value between 0 (fully opaque) and 90.
  The transparency level is limited to 90 % to avoid confusion with layers that are frozen or turned off.

• By Layer - apply the value of the transparency property of the layer.

• By Block - transparency value is controlled by block.

The Transparency value for new hatches is saved by the HPTRANSPARENCY system variable.

Undo

Allows to remove already selected boundaries from the selection.
