The blank editing operations allow you to:

  • hide and show the boundaries of blanks

  • erase blanks

  • cover and uncover entities hidden by blanks.

    Command:

    pdms_blank_edit

    Note:
    Only blanks created by AutoDRAFT can be edited using this facility. You cannot edit blanks applied automatically by Draft.

    Menu Selection:

    Blank>Visible, Blank>Invisible, Blank>Cover, Blank>Uncover, Blank>Erase

    Initial Prompt:

    Visible/Invisible/Cover/Uncover/Erase:

    Use:

    Visible Invisible

    Blank>Invisible (or I at the command prompt) will make all visible blank boundaries invisible.

    Blank>Visible (or V at the command prompt) will make all invisible blank boundaries visible.

    Note:
    Blank boundaries are drawn as purple (AutoCAD colour 194) solid lines.

    If you wish to create a new blank, all invisible blanks must first be made visible.

    pdms_blank makes blanks invisible. In order to see them after a pdms_blank command use pdms_blank_edit Visible.

    pdms_blank_edit Invisible will fail if PDMS_BLANKS is the current layer, returning an error message. To recover from this condition, make a layer other than PDMS_BLANKS the current one.

    Cover Uncover

    Blank>Uncover (or U at the command prompt).

    (Use following a Blank>Create operation but before a Blank>Blank operation.) The prompt changes to:

    Select objects to uncover:

    Select objects:

    Click on the entities that you require not to be hidden by the covering blank. The hit entity will be highlighted. When the last entity has been selected press Enter.

    When the next Blank>Blank operation is carried out, the hit entities will not be hidden by the blank.

    Blank>Cover (or C at the command prompt) can be used to mark as ‘covered’ entities which had previously been marked as ‘uncovered’. The prompt changes to:

    Select objects to cover:

    Select objects:

    Click on the entities that you require to change from being marked as ‘uncovered’ to ‘covered’. The hit entity will be highlighted. When the last entity has been selected press Enter.

    When the next Blank>Blank operation is carried out, the hit entities will be hidden by the blank.

    Note:
    If an object is uncovered it will be seen on top of all blanks, if it is covered it will be covered by all blanks. It is not possible to have a single object covered by one blank, but uncovered by another.

    Erase

    The prompt changes to

    Select blanks to erase:

    Select objects:

    Click on the boundaries of the blanks you wish to erase. The hit blank will be highlighted. When the last blank has been selected press Enter.

    The picture will be redrawn with the outlines of the hit blanks no longer shown.

    Items hidden by erased blanks will still be hidden. Use the AutoCAD regen command to redisplay the ‘unblanked’ items.

    Note:
    If blanks are not visible they will be made visible by this option so they can be selected at the Select objects: prompt. If any objects other than blanks are selected they will not be erased. Blanks can also be deleted with the AutoCAD erase command.
