- X-HATCH is CADKEY shorthand for cross-hatching.
-
- Cross-hatch styles are line patterns that represent
- materials such as copper, glass, or steel. Use cross-
- hatching to fill a specific, enclosed area. When cutting
- or sectioning a part, cross-hatching helps you distinguish
- open space from material.
-
- You can choose from up to eighteen cross-hatch styles or
- customize your own cross-hatch style to suit your needs.
-
- You can also specify the angle and distance between the
- lines for each cross-hatch style.
-
- Each of the lines in the cross-hatch pattern are known as
- hatch lines.
-
- Cross-hatch styles can be either single or double.
-
- The following notes are about using Drawing Layout Mode
- with X-HATCH.
-
- Use DETAIL, XHATCH to cross-hatch something when the
- boundary of the area you want to cross-hatch is made up of
- all instance-specific geometry or all layout-specific
- geometry.
-
- When you change the location of, align, or rotate an
- instance that has cross-hatching in it, the cross-hatching
- moves accordingly.
-
- Do not cross-hatch any layout-specific geometry while you
- have an instance activated. If you want to cross-hatch
- layout-specific geometry, first turn off the active
- instance using INSTANCE, ACTIVE.
-
- Choose entities for cross-hatching from other instances if
- they are hard to access in the active instance.
-
- If you change the view of an instance that you've cross-
- hatched using INSTANCE, MODIFY, VIEW, the cross-hatching
- disappears.
-
- If you cross-hatch in Model Mode and then enter Drawing
- Layout Mode, your drawing instances won't show the
- cross-hatching.
-
- You can use cross-hatching with any of the following
- options:
-
- EDIT, BX MOVE
- XFORM (all options)
- CHANGE, ATTRIBUTE (color, pen #)
- LEVEL, MOVE
- DELETE
- FILE, PATTERN
-
- Before you cross-hatch an entity, trim or break the lines
- that fall beyond the selected boundary.
-
- To cross-hatch an entity follow the steps below:
-
- After you choose DETAIL, X-HATCH, cursor-select a
- cross-hatch style from the X-HATCH pop-up window.
-
- When more cross-hatch patterns exist than will fit in the
- window, click on Nxt. Page in the right corner of the
- pop-up window to view the new patterns. Click on Prv. Page
- to go back to the original list.
-
- Enter, in degrees, an angle value for the slant of the
- hatch lines, or press <Enter> to accept the default.
-
- For single cross-hatch styles, if you type 0, the lines
- are horizontal. For double cross-hatch styles, if you type
- 0, the lines are horizontal and vertical.
-
- Because of the way CADKEY defines certain line patterns,
- Styles 15, MESH, and 18, WINDING, have fixed angles of 0
- degrees.
-
- Enter a value for the distance between hatch lines, or
- press <Enter> to accept the default. The smaller the
- value, the closer the lines; the larger the value, the
- further apart the hatch lines.
-
- For patterns with a blank line, such as STEEL and RUBBER,
- the value you enter represents the distance between the
- closest lines in the pattern.
-
- Select the entities that you want to cross-hatch, making
- sure they form a closed boundary.
-
- CADKEY treats cross-hatching as one entity. Single-select
- the cross-hatch entities by indicating a cross-hatch line
- in one of the extreme limits, or by choosing the WINDOW or
- one of the other methods from the Selection Menu.
-
- When working with multiple viewports, CADKEY asks you to
- cursor select the viewport with the entities you want to
- cross-hatch.
-
- After you make your selection, choose YES from the NO/YES
- menu or press <Enter>. Choose NO to continue single-
- selecting entities without choosing from the Selection
- Menu. Press <Enter> after your selection.
-
- The system begins to cross-hatch. To stop cross-hatching
- at any time, press (Esc).
-
- When CADKEY finishes cross-hatching, you return to the
- Selection Menu.
-
- Like dimension entities, cross-hatch entities are view
- dependent; cross-hatching appears only in the view in
- which you created it.
-
- To cross-hatch another entity using the same pattern,
- select the new entities you want to cross-hatch. To
- cross-hatch another entity with a different pattern,
- repeat the steps listed above.
-
- An island is an area inside another area.
-
- You can select islands to include cross-hatching. Cross-
- hatching draws from the outermost selected boundary until
- it reaches the first selected island. From there, CADKEY
- stops cross-hatching until it reaches the next selected
- island and so on. Be careful when you select your
- boundaries.
-
- An island can be as many levels deep as you want, as long
- as the island consists of a closed boundary of entities.
-
- Cross-hatching ignores entities you don't select. Edit
- entities with EDIT, BREAK to form a perfectly closed
- boundary.
-
- Make sure you select all boundaries of an area or CADKEY
- will cross-hatch the area incorrectly.
-
- Once you select the islands you want to cross-hatch,
- follow the steps above to cross-hatch an entity.
