Setting Change Style Attributes

This Section describes the use of the lower parts of the Change Design Library and Change Annotation Library forms to modify the attribute settings for the currently highlighted DCSTYL or ACSTYL.

Setting Change Design Style Attributes

The lower part of the Change Design Library form consists of sets of gadgets that allow you to modify the attribute settings for the currently highlighted DCSTYL.

1. To modify any of the attribute settings for the current DCSTYL, change the settings of the corresponding gadgets (as explained in the following paragraphs).

2. Click the Apply button.

   

   The lower part of the form allows the assignment of styles and colours to the six line types (that means, Frontface, Backface, etc) equivalent to those of a Representation Style (STYL), and to the single line type (that means, Outline) and single Hatch pattern equivalent to those of a Hatching Style (HSTYL).

3. For all eight of these line types you can assign a colour and either a Standard style or a User-defined style. A colour may also be set to ‘Unchanged’ and a style to ‘Unchanged’ or ‘Off’.

4. Colours can either be selected from a drop-down list (initially populated with the basic 16 system-defined colours and the ‘Unchanged’ option) or picked from a colour-palette shown when the Pick button is clicked.

   The colour selector gadgets will be greyed out if the Style is ‘Off’.

5. Standard linestyles are selected from two drop-down list gadgets: the first allowing ‘Unchanged’ or ‘Off’ or one of the 10 standard system-defined line-patterns to be selected, and the second allowing one of the three standard system-defined line-widths to be selected.

6. The Standard fillstyle is selected from the drop-down list gadget.

   A total of 18 standard system-defined fillstyles are provided as well as ‘Unchanged’, ‘Off’, and ‘Solid Fill’.

7. If a User-defined Style is required click Select.

   This will cause the Standard Style gadgets to be greyed out and the User-defined Linear (or Fill) Styles selection form to be displayed.

   The left-hand side of this form lists all the Linestyle (or Fillstyle) Tables found in the MDB.

8. Selecting one of these Linestyle (or Fillstyle) Tables causes the right-hand side to be populated with the Table’s Styles from which a selection can be made.

9. Once a User-defined style is selected, the checkbox can be used to toggle between the standard style and the User-defined style.

Setting Change Annotation Style Attributes

The lower part of the Change Annotation Library form consists of sets of gadgets that allow you to modify the attribute settings of the currently highlighted ACSTYL. These attributes control the appearance of changed annotation graphics (lines and hatching) and text strings.

• To modify any of these settings for the selected ACSTYL, change the settings of the corresponding gadgets (as explained in the following paragraphs) and click the Apply button.
