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 [Reference]: select Reference.
5. Specify the reference angle <0>: Snap to the reference object (1) and (2).
6. Specify the new angle or [Points]: P <enter>.
7. Specify first point: select 1st endpoint of new angle.
8. Specify second point: select 2nd endpoint of new angle.
The SCALE command is used to make objects larger or smaller proportionately. You may scale using a scale factor or a reference length. You must also specify a base point. The base point is a stationary point from which the objects scale.
1. Select the SCALE command using one of the following:
| Ribbon = Home tab / Modify Panel / orKeyboard = scale <enter> |
|
SCALE FACTOR
Command: _scale
2. Select objects: select the object(s) to be scaled
3. Select objects: select more object(s) or <enter> to stop
4. Specify base point: select the stationary point on the object
5. Specify scale factor or [Copy/Reference]: type the scale factor <enter>
If the scale factor is greater than 1, the objects will increase in size. If the scale factor is less than 1, the objects will decrease in size.
REFERENCE option
Command: _scale
2. Select objects: select the object(s) to be scaled
3. Select objects: select more object(s) or <enter> to stop
4. Specify base point: select the stationary point on the object
5. Specify scale factor or [Copy/Reference]: select Reference
6. Specify reference length <1>: specify a reference length
7. Specify new length: specify the new length
COPY option - creates a duplicate of the selected object. The duplicate is directly on top of the original. The duplicate will be scaled. The Original remains the same.
The STRETCH command allows you to stretch or compress object(s). Unlike the Scale command, you can alter an objects proportion with the Stretch command. In other words, you may increase the length without changing the width and vice versa.
Stretch is a very valuable tool. Take some time to really understand this command. It will save you hours when making corrections to drawings.
When selecting the object(s) you must use a CROSSING window. Objects that are crossed, will stretch. Objects that are totally enclosed, will move.
1. Select the STRETCH command using one of the following:
| Ribbon = Home tab / Modify Panel / orKeyboard = S <enter> |
|
Command: _stretch
2. Select objects to stretch by crossing-window or crossing-polygon...
Select objects: select the first corner of the crossing window
3. Specify opposite corner: specify the opposite corner of the crossing window
4. Select objects: <enter>
5. Specify base point or [Displacement] <Displacement>:
select a base point (where it stretches from)
6. Specify second point or <use first point as displacement>:
type coordinates or place location with cursor
The TRIM command is used to trim an object to a cutting edge. You first select the “Cutting Edge” and then select the part of the object you want to trim. The object to be trimmed must actually intersect the cutting edge or could intersect if the objects were infinite in length.
1. Select the Trim command using one of the following:
| Ribbon = Home tab / Modify Panel / orKeyboard = TR <enter> |
|
2. The following will appear on the command line:
Command: _trim
Current settings: Projection = UCS Edge = Extend
Select cutting edges ...
Select objects or <select all>: select cutting edge(s) by clicking on the object (P1)
Select objects: stop selecting cutting edges by pressing the <enter> key
Select object to trim or shift-select to extend or
[Fence/Crossing/Project/Edge/eRase/Undo]: select the object that you want to trim. (P2) (Select the part of the object that you want to disappear, not the part you want to remain)
Select object to trim or [Fence/Crossing/Project/Edge/eRase/Undo]: press <enter> to stop
Note: You may toggle between Trim and Extend. Hold down the SHIFT key and the Extend command will activate. Release the SHIFT key and you return to Trim.
Fence Use a “Fence” line to select objects to extend.
Edge See page 1-23
Project Same as Edge except used only in “3D”
