Feature Control Frame Dialog Box (AutoCAD Mechanical Toolset)

Use this dialog box to describe the allowable variation from nominal geometry.

Symbol tab

 

Requirements

Contains buttons and edit boxes to specify the variations. These are named only in tooltips. Move the pointer over them to identify them.

   

Insert symbol

Displays a palette enabling you to insert a special character at the current cursor position. The preview in the drawing area shows the special character while the dialog box shows the corresponding control key sequence.

   

Top Notes

Specifies text that must display above the feature control frame. In the drawing area the notes and the feature control frame move together as a single entity.

   

Geometric symbol

Displays a list of symbols to enable you to specify the geometric characteristic for which you are defining the tolerance. The symbols on this list depend on the current standard.

   

Tolerance 1

Specifies primary tolerance data. Use the Insert symbol list to insert special characters such as the diameter symbol or the maximum material condition symbol.

   

Tolerance 2

Specifies secondary tolerance data. This option is available only for the ANSI standard.

   

Datum 1

Specifies the primary datum from which the tolerance is measured.

   

Datum 2

Specifies the secondary datum from which the tolerance is measured.

   

Datum 3

Specifies the tertiary datum from which the tolerance is measured.

   

Bottom Notes

Specifies text that must display below the feature control frame. In the drawing area the notes and the feature control frame move together as a single entity.

   

All Around

Adds the all around indication to the symbol. This option is unavailable for the GOST standard.

 

Library

Lists all feature control frame symbols in the symbol library, for the current drafting standard.

   

Menu Options

     

Load

Loads the settings of the selected symbol to the Feature Control Frame dialog box. This operation overwrites the current settings of the Feature Control Frame dialog box.

     

Update

Overwrites the selected symbol in the library, with the current settings of the Feature Control Frame dialog box. The preview updates to reflect the new settings. The name of the symbol and default status do not change.

     

Delete

Removes the selected symbol from the library.

     

Rename

Makes the symbol name editable. AutoCAD Mechanical toolset validates the name to ensure that the symbol names are unique.

     

Set default

Makes the selected symbol the default symbol of the library. A blue check mark appears next to the symbol to indicate that it is the default symbol. The next time you create a feature control frame symbol, the default symbol loads automatically.

     

Remove default

Removes the default status of the selected symbol. This menu option is available only on the default symbol. When there is no default symbol selected, the settings default to the settings of the feature control frame symbol you created or edited most recently.

   

Add

Saves current settings to the symbol library as a new item in the library. A prompt enables you to name the new item.

   

Import

Imports the feature control frame symbols from the symbol library of another drawing. You can only import symbols of the same standard and revision as the feature control frame symbol you are editing.

 

Clear

Clears all the data and returns the dialog box options to the default values.

Leader and Text tab

 

Leader

   

Primary arrowhead

Specifies the type of the primary leader arrowhead. When the arrowhead is set to By Standard, it acquires the arrowhead from the current drafting standard. Thereafter, if you change the arrowhead selected for the current drafting standard (in the Standard Settings dialog box or Feature Control Frame Settings dialog box) the arrowhead for this symbol updates automatically.
   

Secondary arrowhead

Specifies the type of the secondary leader arrowhead. When the arrowhead is set to By Standard, it acquires the arrowhead from the current drafting standard. Thereafter, if you change the arrowhead selected for the current drafting standard (in the Standard Settings dialog box or Feature Control Frame Settings dialog box) the arrowhead for this symbol updates automatically.

   

Surface arrowhead

Specifies the type of arrowhead to use at the end of the surface indication leader. When the arrowhead is set to By Standard, it acquires the arrowhead from the current drafting standard. Thereafter, if you change the arrowhead selected for the current drafting standard (in the Feature Control Frame Settings dialog box) , the arrowhead for this symbol updates automatically.

Note:

This option is available only if a surface indication line exists for the symbol you are editing.

    Edit leader/segments
     

Add

Adds a leader, leader segment(s), or leader node(s).

     

Remove

Deletes a leader, or leader segment(s).

    Edit object attachment
     

Attach

Attaches the symbol to a geometry in the drawing.

     

Detach

Detaches the symbol. The symbol becomes a free-standing object.

 

Surface extension line

Controls options for extension lines to the start point of the leader. Extension lines are drawn only if you move the start point of the leader beyond the end of the line or arc it is attached to. The options in this section are available only if extension lines for this symbol exist.

   

Offset from object

Defines the distance between the extension line’s start point and the attached object.

     

Sync

Loads values for the offset from the DIMEXO system variable.

   

Extension beyond leader

Defines the distance between the leader start point and the extension line end point.

     

Sync

Loads values for the extension from the DIMEXE system variable.

Settings

Opens the Feature Control Frame Settings dialog box, enabling you to edit the default settings for the current drafting standard.
