The Nudge option allows you to nudge objects in orthogonal increments.
Note:
Snap mode affects the distance and direction in which the objects are nudged.
Nudge objects with Snap mode turned OFF: Objects move two pixels at a time.
Nudge objects with Snap mode turned ON:
Objects are moved in increments specified by the current Snap spacing.
EXAMPLE:
1. Draw a Circle.
2. Select the Circle.
5 little boxes appear. These are Grips and allow you to edit the object. Grips will be discussed more in future lessons.
3. Hold down the Ctrl key and press one of the Arrow keys
Remember:
The distance the object moves depends on whether you have the Snap mode ON or OFF. (Refer to note above)
The OFFSET command duplicates an object parallel to the original object at a specified distance. You can offset Lines, Arcs, Circles, Ellipses, 2D Polylines and Splines. You may duplicate the original object or assign the offset copy to another layer.
Examples of Offset objects.
HOW TO USE THE OFFSET COMMAND:
METHOD 1
(Duplicate the Original Object)
1. Select the OFFSET command using one of the following:
Ribbon = Home tab / Modify Panel / orKeyboard = offset <enter> |
|
2. Command: _offset
Current settings: Erase source=No Layer=Source OFFSETGAPTYPE=0 Specify offset distance or [Through/Erase/Layer] <Through>: type the offset distance or select Erase or Layer. (see options on the next page)
3. Select object to offset or <Exit/Undo>: select the object to offset.
4. Specify point on side to offset or [Exit/Multiple/Undo]<Exit>: Select which side of the original you want the duplicate to appear by placing your cursor and clicking. (See options on the next page)
5. Select object to offset or [Exit/Undo]<Exit>: Press <enter> to stop.
METHOD 2
(Duplicate original object but assign the Offset copy to a different layer)
To automatically place the offset copy on a different layer than the original you must first change the “current” layer to the layer you want the offset copy to be placed on.
1. Select the layer that you want the offset copy placed on from the list of layers.
2. Select the OFFSET command (refer to previous page)
3. Command: _offset
Current settings: Erase source=No Layer=Source OFFSETGAPTYPE=0 Specify offset distance or [Through/Erase/Layer] <Through>: type L <enter>
4. Enter layer option for offset objects [Current/Source] <Source>: select C <enter>
5. Specify offset distance or [Through/Erase/Layer] <Through>: type the offset distance <enter>
6. Select object to offset or [Exit/Undo] <Exit>: select the object to offset.
7. Specify point on side to offset or [Exit/Multiple/Undo]<Exit>: Select which side of the object you want the duplicate to appear by placing your cursor and clicking. (See options below)
8. Select object to offset or [Exit/Undo]<Exit>: Press <enter> to stop.
OPTIONS:
Through: Creates an object passing through a specified point.
Erase: Erases the source object after it is offset.
Layer: Determines whether offset objects are created on the current layer or on the layer of the source object. Select Layer and then select current or source. (Source is the default)
Multiple: Turns on the multiple offset mode, which allows you to continue creating duplicates of the original without re-selecting the original.
Exit: Exits the Offset command.
Undo: Removes the previous offset copy.
The ROTATE command is used to rotate objects around a Base Point. (pivot point) After selecting the objects and the base point, you will enter the rotation angle from its current rotation angle or select a reference angle followed by the new angle.
A Positive rotation angle revolves the objects Counter-Clockwise. A Negative rotation angle revolves the objects Clockwise.
Select the ROTATE command using one of the following:
Ribbon = Home tab / Modify Panel / orKeyboard = RO <enter> |
|
ROTATION ANGLE OPTION
Command: _rotate
1. Current positive angle in UCS: ANGDIR=counterclockwise ANGBASE=0 Select objects:
select the object to rotate.
2. Select objects: select more object(s) or <enter> to stop.
3. Specify base point: select the base point (pivot point).
4. Specify rotation angle or [Copy/Reference]<0>: type the angle of rotation.
REFERENCE OPTION
Command: _rotate
1. Current positive angle in UCS: ANGDIR=counterclockwise ANGBASE=0
