Hatches an area using a selected image, block, xref, or wipeout object.
SUPERHATCH displays the SuperHatch dialog box.
|Image||Opens the Attach Image dialog box for specifying the image for the superhatch pattern.|
|Block||Opens a dialog box for specifying the block for the superhatch pattern.|
|Xref Attach||Opens the Xref File Name dialog box for specifying an xref file for the superhatch pattern.|
|Wipeout||Uses a wipeout object for the superhatch pattern.|
|Select Existing||Selects an existing image, block, xref, or wipeout object for the superhatch pattern.|
|Curve Error Tolerance||Specifies the error tolerance for the vector approximation of curved superhatch boundaries.|
You can use the Block option to create hatch patterns on-the-fly; you can created blocks with different layers, colors, and linetypes to create hatch patterns that react to layer states and plot with a variety of line weights. You can use hatch images on surfaces to get a rendered effect. Use 3D blocks as hatch patterns to place repeating items such as bricks, roof tiles, or fence fills in 3D drawings.
Insertion point <0,0>: Specify an insertion point
Base image size: Width: 1.00, Height: 0.24 <Unitless>
Scale factor <1>: Specify a scale factor
For blocks and xrefs:
Insertion point: Specify an insertion point
X scale factor <1> / Corner / XYZ: Specify the X scale factor
Y scale factor (default=X): Specify the Y scale factor
Rotation angle <0>: Specify the rotation angle
Specify a window around the block to define column and row tile distances.
Specify block [Extents] First corner <magenta rectang>: Specify a tiling (tesselation) frame, and press Enter
Specify an option [Advanced options] <Internal point>: Specify an internal point for hatch boundary, or enter A for advanced options, and press Enter
For images and wipeout objects:
Use TFRAMES to turn on and off the object frames.
Error tolerance for curves:
SUPERHATCH makes hatching to curved boundaries possible by traversing arc segments with a series of short straight segments. SUPERHATCH lets you to control the precision with which it traverses arc segments by allowing you to specify the maximum distance between the midpoint of any given segment and the arc. (See the Curve Error Tolerance option described in the Dialog Box Options above.)
Maximum error distance for resolution of arcs:
Entering a large error value results in fewer segments and faster performance, but arcs appear less smooth. Conversely, entering a very small value results in smooth hatching along arcs but places more of a processing burden during regeneration of a drawing.
In this example, a block is used to create a superhatch pattern.
Insert the block:
Specify the framing around the block:
Specify the boundary:
Superhatch objects are glued together using unnamed groups. Therefore, they are not associative. If you want to modify a single object that is part of a superhatch, you can use the GROUP command to turn off selection of the group as follows:
1) Start the group command.
2) Make sure that the Include Unnamed check box is selected.
3) Select the group. Note that "superhatch" appears in the description field for groups created by SUPERHATCH.
4) Click Selectable.
5) Choose OK.
The individual objects can now be modified separately.
