Edit Object Properties Form – Note Shapes

You use the Previous and Next buttons along with the Apply To options below to locate objects in your design window. When there are multiple objects in the selected set, you use the Next and Previous buttons to locate objects in the set. You use the Apply To options to specify the objects the software changes.

Previous cycles backward to view the preceding object in the selected set. When you reach the first object in the selected set, this button has no effect.

Next cycles forward to view the next object in the selected set. When you reach the last object in the selected set, this button has no effect.

Apply To consists of up to three cyclic fields that you use to specify the object, or group of objects in a selected set, whose properties you want to change. The software uses one color to highlight selected objects. But when there are multiple objects in the selected set, the software uses a second color to highlight the current object. And when you configure the cyclic fields to apply changes to multiple objects, the software uses a third color to highlight all the affected objects.

Selection scope specifies whether you want to edit only the current object, only the selected objects in the specified object type group, or all the objects in the specified object type group (which includes both selected and unselected objects of the specified object type).

Object group lists the object types in the selected set. Use this option to locate the first object of a particular object type.

Property lists the properties that the system automatically extracts from the design database.

Value displays the values for the corresponding properties.

Line Style specifies whether the system uses a solid or dashed line to draw the note shape.

The form displays various options depending on the shape type you select.

The following options appear when you select a line shape.

Width specifies whether the line shape is narrow (default) or wide. You can edit the text field when you enable thewide option.

Points List specifies the coordinates for the points that make up the shape.

The following option appears when you select a polygon shape.

Point List specifies the coordinates for the points that make up the shape.

The following options appear when you select a rectangle shape.

Upper Right specifies coordinates that define the upper right-hand corner of the shape.

Lower Left specifies coordinates that define the lower left-hand corner of the shape.

The following options appear when you select either a circle shape or an ellipse shape. Note that the Shape text field displaysellipse for both circle and ellipse shapes.

Center specifies the coordinates that define the center of the shape.

X Radius specifies the coordinate that defines the Xradius of the shape.

Y Radius specifies the coordinate that defines the Yradius of the shape.

The following options appear when you select an arc shape.

Center specifies the coordinates that define the center of the shape.

X Radius specifies the coordinate that defines the Xradius of the shape.

Y Radius specifies the coordinate that defines the Yradius of the shape.

Start Angle specifies the first point of the arc.

Stop Angle specifies the second point of the arc.

Object group lists the object types in the selected set. Use this option to locate the first object of a particular object type.

Attachment performs two functions.

■When the text is already associated with an object, the software highlights the associated object in the cellview.

■Lets you associate the note text with an object in the cellview by automatically drawing a line from the text to the object when you move the cursor into the design window.

Note Text specifies the text for your note. You can either type in the text or useRead File to load the text from a file. You can edit any text you load into the this edit window.

Read File loads text from the specified file into theNote Text edit window.

Height lets you specify the height of the note text.

Font lets you select a font for the note text.

Justification lets you specify where the note text appears in relation to its origin (placement location).

Drafting, when enabled (default), maintains the normal orientation of the note text as you rotate a label 180 degrees around a reference point. When this option is disabled, rotated text appears upside down.

Overbar is only a display option. You use this option to specify whether the software displays an overbar over the note text. When this option is disabled (default), the software displays underscore characters ( _ ) in the note text as part of the note text string. When this option is enabled, the software interprets underscore characters ( _ ) in the note text as toggle switches that control where overbars begin and end. Overbars appear above the note text, as shown in the examples.

_abcde abcde

ab_cde abcde

_abc_de abcde

ab_cd_ef_gh_ij abcdefghij

To avoid confusion when text actually contains underscore characters, Cadence recommends that you disable this display option. It is provided only for backward compatibility.
