The first two pages are typical for all Modules:they provide the Module title and set out the learning objectives. The suggested time forcompletion of the Module is given at the end of Page 9-2.

3 It is usedto add material or textural information to a drawing in the form of hatch lines orpatterns of symbols. Every discipline uses patterns of some kind; engineeringdrawings show cut materials with hatches, surveying drawings show groundcover symbols, and geological drawings show rock material types as patterns. As you will see, MicroStation uses lines and cells to create hatches and patterns,and you will use the concepts discussed in the previous Module to createboundaries to contain the hatches and (s) single-line hatches using the Hatch Area double-line hatches using the Place Crosshatch the seven Methods of placing a cell patterns using the Pattern Area associative patterns and discuss their the attributes and display of patterns using the four pattern deletion methods of patterning around Show Pattern, Match Pattern Attributes, and Change Pattern the options for the Linear Pattern :This Module should be completed within 4 hours.

4 Module 9 - Page 2 Single-Line HatchCross HatchPattern CellDISCUSSION: MicroStation provides two basic methods of adding hatching or patterns to drawings:Line ElementsSimple hatching is achieved by applying either single-line (hatching) or double-line (crosshatching) elements to a defined is achieved by applying a pattern cell to a defined three types of patterns look like this:The terms hatch and pattern are essentially interchangeable, although Patterning is the official MicroStationterm. In this Module I am generally using hatch to describe line patterns, and pattern to describe patterningwith a a hatch or a pattern to be successfully applied there are two statements that can be made:Ideally, the geometry of the drawing elements should be as accurate as possible.

5 Accuracy in this casemeans having the vertices of the enclosing elements connected. Nothing will stop the patterning processfaster than a gap between enclosing elements! For most of the hatching or patterning tools, MicroStation requires there to be a closed element presentbefore a pattern will take place. This is particularly so if the pattern is to be associative (where thepattern is bound to the closed element). Depending on the method used, you may need to create closedelements before starting the patterning you start, click on the Hatch Area tool in the Annotate/Patterns group and look at theTool Setting window. The window looks very similar to the Regions window from the previousModule, and with good reason.

6 Hatching and regions are a natural mixsince a hatch must be bounded by something, whether a single closedelement, or several elements form an you will see, Boolean operations can also be part of the hatchingprocess when using the Flood tool take a closer look at the tools: Module 9 - Page SINGLE-LINE HATCHESS tart by drawing a closed shape:Step 1 Draw a block rectangle with dimensions of 3'-0" (900) high, by 2'-0"(600) 2 Start the Hatch Area tool in the Pattern group and select the Elementoption. Look at the Tool Settings window. The options are (depending on which tool is activated):SpacingSets the spacing of the hatch lines in working the angle of the hatch lines (standard counterclockwiserotation).

7 Drop PatternIf OFF (default), pattern elements are associated with the boundary. If ON, the pattern elements are not associated and are created asstatic elements in a graphic is associated with a regional boundary, depending on thehatching tool used. See the Help files for more On, allows snapping to the hatch lines. Normally this option isoff since a dense hatch can interfere with snapping to elements nearthe forHolesIf the element to be hatched has holes (hole elements or holes aspart of a region), the hole can be hatched over or left clear ofhatching. The search can be for holes on the same Level as theelement, or on all levels. Option activates with Drop Pattern 3 Set the option values to those shown in theillustration.

8 The spacing is 3" (75).You will use the Element method because the block you drewis a closed element. Follow the prompts in the Status Line:Step 4 Data-point to select the next prompt is to Accept @ patternintersection point. MicroStation is asking you toselect a point through which a line of the hatchwill be drawn. In other words, you control wherethe hatch is started:Step 5 Snap to the upper-left corner of the will force the hatch to start at this corner. Since you have set the spacing at 3"(75), the hatch will display as 450 lines spaced at 3" (75). Module 9 - Page 4 The spacing option requires some comment. Clearly, you can control the spacing value to bestadvantage.

9 For example, if you were designing a deck and you wanted to see the effects of placing6" (140) planks at different angles and starting points, it is very easy to set suitable values and placeseveral plank layouts in copies of the deck outline. Similarly, if you are hatching a machine part andthe material hatching symbol requires that the hatch spacing be 1/8" (3), you can control the spacingvalue so that the hatch will plot at 1/8" (3) at whatever plot scale you are your own, repeat this hatch placement process, changing the spacing and angle options and data-pointing in other locations to locate the hatch. Also, try the Flood method where you data-pointinside the area to be hatched.

10 You will look at Boolean operations a little HATCHESYou will often need to align hatches between adjacent areas. For example, return to thefoundation detail you created from cells in Module 7. Look at the first part of thatdrawing, the footing and the foundation concrete material will need hatching, but there are two separate areas. It wouldlook better if the hatching in each area was aligned. To do this you need a common hatchintersection point for both areas. In the illustration at the left, the common intersection point is theupper-left corner of the footing as shown by the red circle. Both hatches were placed by the Floodmethod using that common intersection point, resulting in aligned hatched between both common intersection point can be anywhere and does not need to be on the element to CROSSHATCHESC rosshatches are the same as single-line hatches except that youare offered two spacing and angle settings:Step 1 Start the Crosshatch Area tool.
