How to Scale Objects in AutoCAD Layouts

Scaling in AutoCAD can refer to several actions, especially when working in a layout tab. The provided reference describes how to scale objects within your drawing using the SCALE command. This process works the same whether you are in Model Space or a Layout tab.

Here's a breakdown of how to use the SCALE command based on the provided steps:

The SCALE command allows you to enlarge or reduce selected objects proportionally based on a base point and a scale factor.

Steps to Scale Objects Using the SCALE Command

Applying the SCALE command is a straightforward process. You can scale individual objects or groups of objects simultaneously.

1. Select Object(s): Begin by selecting the specific object or multiple objects you wish to scale. You can do this by clicking on them or using selection windows (Window or Crossing).
2. Initiate the Command: Type SCALE in the command bar located typically at the bottom of your AutoCAD window, and then press the Enter key.
3. Specify Base Point: AutoCAD will prompt you to select a base point. This is the point that will remain fixed during the scaling operation. All selected objects will be scaled relative to this point. Click a point in your drawing or type coordinates.
4. Enter Scale Factor: Type the desired numerical scale factor in the command bar and press Enter.
   • A scale factor greater than 1 will enlarge the object(s).
   • A scale factor between 0 and 1 (e.g., 0.5) will scale down the object(s).
   • A scale factor of 1 will result in no change in size.

Example:

To double the size of selected objects, enter 2 as the scale factor. To reduce them to half size, enter 0.5.

Understanding "Layout XP"

It's important to note that the term "layout xp" commonly refers to setting the scale of a Model Space viewport within a Layout tab for plotting purposes. This scale is expressed as a ratio (e.g., 1:100) followed by 'xp' (e.g., 1/100xp or 0.01xp), which signifies "times paper space".

Setting a viewport scale using 'xp' is distinct from using the SCALE command to change the actual size of objects in your drawing. The SCALE command modifies the dimensions of objects, while setting a viewport scale adjusts how large those objects appear when viewed through a specific viewport on your paper space layout, without changing their real-world dimensions in Model Space. The provided reference specifically details the SCALE command for object modification.

Summary Table: SCALE Command Steps

Step	Action	Notes
1. Select Objects	Choose the items to resize.	Can be one or many.
2. Start Command	Type SCALE, press Enter.	Activates the scaling function.
3. Select Base Point	Click a fixed point or enter coordinates.	Objects scale relative to this point.
4. Enter Scale Factor	Type a number (>1 to enlarge, <1 to reduce), press Enter.	Determines the degree of scaling.

Using the SCALE command is fundamental for adjusting the size of drawing elements accurately in AutoCAD, whether you are detailing in Model Space or preparing elements within a Layout tab.
