Create and Apply Local Hatching Rules

DRAW User Guide

Create and Modify Views : Format 2D View : Create and Apply Local Hatching Rules

Creates local hatching rules and applies them to items in the view drawlist, overriding the selected discipline specific rules for those items.


CE	Click to identify the currently selected view as the working element.
Views	Select the view for the sheet from the drop-down list.
Rules	Select a hatching rule from the list.
Create	Allows you to create a hatching rule. Click to display the Create HRUL window. Input a name for the new rule in the Name field. Click OK to add the rule to the Rules list or Cancel to discard any changes and close the Create HRUL window.
Delete	Click to delete the currently selected hatching rule from the Rules list.
For	Allows you to specify the items that the rule is applied to. Select the Menus option button and select the elements the rule is applied to from the drop-down list. Select the Names option button and click Modify to display the Names window. Refer to Names for further information.
With	To apply qualifying restrictions to the elements specified in the For section, input an expression in the With field. For example, if the For section specifies Branches, the following can be input: (HBOR GT 100) AND (TBOR GT 80) meaning 'Branches with HBOR greater than 100mm and TBOR greater than 80mm'.
Style	Select the check box to associate the hatching rule with a representation style.
Styles	Select a representation style library from the upper drop-down list. Select a style from the lower list.
Display	Displays a graphical representation of the selected style from the lower Styles list.
Attributes	Allows you to define the hatching rule attributes. Refer to Hatching Rule Attributes for further information.

Click Apply to apply the hatching rules or Cancel to discard any changes and close the Local Hatching Rules window.

Hatching Rule Attributes

Sets the hatching rule attributes.


Consider	Select only sectioned surfaces from the drop-down list to specify that only surfaces cut by a section plane are considered. Select all primitive surfaces from the drop-down list to specify that the element need not be cut by a section plane to be considered.
Plot	Allows you to view the Hatching Rule Attributes Plot window which illustrates the hatching rule attributes. Refer to Hatching Rule Attributes Plot for further information.
Hatching	Allows you to refine a hatching rule. Select the All surfaces in all directions option button to specify that all surfaces meeting the criteria in the Consider list are hatched. Select the Only surfaces perpendicular to view direction option button to specify that only those surfaces perpendicular to the view are hatched. For example, if the view direction is north, the south face of the element is hatched, assuming it meets the criteria in the Consider list. Select the Only surfaces facing in the specified direction option button to specify a direction normal to the surface to be hatched, instead of using the view direction. For example if a box displays in an isometric view with the top surface crosshatched and six surfaces of a box are required to have different hatching styles, this option would be used on six Hatching Rules.
Direction	The functionality is only available when the Only surfaces facing in the specified direction option button is selected. Input a direction in the field or select the direction from the drop-down list.
Derived	The functionality is only available when the Only surfaces facing in the specified direction option button is selected. Click to select a design element. The Direction (Y) window displays. Refer to Direction for further information.

Click Apply to apply the hatching rules or Cancel to discard any changes and close the Local Hatching Rules Attributes window.

Hatching Rule Attributes Plot

Displays an illustration that represents the defined hatching rule attributes.

You can view the hatching rule attributes.

Direction

Specifies a direction normal to the surface to be hatched.

You are prompted to Identify Design element for Derived Direction

Select an element to display the Direction (Y) window.


CE	Click to identify the currently selected element as the working element.
Direction	Input a value in the field to modify the direction. For example, input N to define a North direction.
wrt	Displays the element that the direction is defined with respect to and can be modified.

The General drop-down menu allows you to define the direction from the CE or the owning element of the CE in the hierarchy.


CE
X direction	Select from the drop-down menu to define the direction from the X axis of the CE.
y direction	Select from the drop-down menu to define the direction from the y axis of the CE.
Z direction	Select from the drop-down menu to define the direction from the Z axis of the CE.
Owner
X direction	Select from the drop-down menu to define the direction from the X axis of the owning element of the CE.
y direction	Select from the drop-down menu to define the direction from the Y axis of the owning element of the CE.
Z direction	Select from the drop-down menu to define the direction from the Z axis of the owning element of the CE.

The Cursor drop-down menu allows you to define the direction from an element, design point or Pline.


Element
X direction	Select from the drop-down menu to define the direction from the X axis of an element using a cursor pick in the view. You are prompted to Identify Element
y direction	Select from the drop-down menu to define the direction from the Y axis of an element using a cursor pick in the view. You are prompted to Identify Element
Z direction	Select from the drop-down menu to define the direction from the Z axis of an element using a cursor pick in the view. You are prompted to Identify Element
Design Point	Select from the drop-down menu to define the direction from a design point using a cursor pick in the view. You are prompted to Identify Design Point
Pline	Select from the drop-down menu to define the view direction from a Pline using a cursor pick in the view. You are prompted to Identify Pline

The Intersection drop-down menu allows you to define the direction from two items using a cursor pick.

The derived direction is at the intersection of the two items, or if they do not actually intersect, at a point on the first picked item which corresponds to the projection of the second item onto the first.


Element	Prompts you to pick an element which has its principal axis pointing through or towards the required position.
Design Point	Prompts you to pick a design point which is aligned through or towards the required position.
Pline	Prompts you to pick a pline which is aligned through or towards the required position.

The Points drop-down menu allows you to select three elements or design points on the drawing canvas to define the direction.


Elements	Prompts you to pick three elements which have their principal axis pointing through or towards the required position.
Design Points	Prompts you to pick three design points which have their principal axis pointing through or towards the required position.

Click Apply to set the defined direction or Dismiss to discard any changes and close the Direction (Y) window.
