AutoCAD Multileaders
(MLEADERSCALE Explained)

How Multileaders Fit Into the System

At this point, we’ve built a complete system:

• TEXTSIZE controls text
• DIMSCALE controls dimensions

Both depend on the same scale factor.

Now we apply that same idea to multileaders.

Why Multileaders Sometimes Look Wrong

A common problem is:

• Text looks correct
• Dimensions look correct
• But leaders are too large or too small

This happens when multileaders are not scaled correctly.

What Does “Hybrid” Mean for Multileaders?

Multileaders are a hybrid because they combine two systems:

• Text behavior
• Dimension behavior

The text portion:

Uses a text style (font)
Has its height defined in the multileader style

Important:

TEXTSIZE is not used for multileaders

The height is set directly in the style as a paper height.

For example:

0.125 = 1/8″ text on paper

How Multileaders Use Scaling

The leader portion behaves like dimensions.

It includes:

• Arrows
• Landing distance
• Spacing

These elements must scale with the drawing.

This is where scaling comes in.

How MLEADERSCALE Relates to DIMSCALE

This is the key connection:

If your DIMSCALE is 24
Then your MLEADERSCALE should also be 24

So again:

• Viewport scale ? gives you scale factor
• DIMSCALE = scale factor
• MLEADERSCALE = same number

Applying What You Already Know

You are not learning a new system.

You are reusing the same one.

From Lesson 4:

• Dimension style text height = paper size (1/8″)
• DIMSCALE = scale factor

Now for multileaders:

• Multileader text height (in style) = paper size (1/8″)
• MLEADERSCALE = scale factor

Everything will match automatically.

Do You Need Multiple Multileader Styles?

No.

In most cases, you only need one primary multileader style.

That style should be set up with:

• Text height = paper size (1/8″)
• Your preferred text style
• Your preferred arrow style

Once that is set:

You do not need separate styles for different scales

How Scaling Actually Happens

All other elements are scaled automatically using MLEADERSCALE.

This includes:

• Arrow size
• Landing distance
• Spacing
• Overall appearance

So instead of creating multiple styles for different scales:

You keep one style
You change MLEADERSCALE

Why This Matters

Creating multiple styles leads to:

• Confusion
• Inconsistent drawings
• More setup time

Using one style with MLEADERSCALE keeps everything:

• Simple
• Consistent
• Easy to manage

How to Fix Existing Multileaders

If a multileader is not scaled correctly:

Select the multileader
Open Properties (CTRL + 1)

Find:

Overall Scale

Adjust it to match your scale factor.

Example:

Incorrect value ? 4.5
Correct value ? 3

Once updated, the leader will match your drawing.

Important AutoCAD Commands for Multileaders

MLEADER
Creates multileaders

MLEADERSTYLE (MLS)
Opens the multileader style manager
Used to define text height (paper size), arrow style, and formatting

MLEADERSCALE
Sets the overall scale (must match scale factor)

PROPERTIES (CTRL + 1)
Used to fix existing multileaders

Important Reminder

The text height for multileaders is set in the style (paper size).

MLEADERSCALE applies the scale.

TEXTSIZE is not used for multileaders

The Core Idea Behind Multileaders

Everything now follows the same system:

Viewport = controls scale
Scale factor = the number behind it

• TEXTSIZE = text
• DIMSCALE = dimensions
• MLEADERSCALE = multileaders

They all use the same number

The Only Rule for Multileaders

Set text height in the style to paper size

Set MLEADERSCALE to match your scale factor

Use one style and let the scale factor do the work

Quick Check

If your multileaders do not match your drawing, what should you adjust?

A) Change viewport scale
B) Change MLEADERSCALE
C) Scale the drawing

AutoCAD Multileaders FAQ

What does MLEADERSCALE control?
MLEADERSCALE controls the overall size of multileaders, including arrows and spacing.

Why do my multileaders not match my dimensions or text?
Because MLEADERSCALE does not match your scale factor.

Does TEXTSIZE control multileader text?
No. The text height is defined in the multileader style using paper size.

How is multileader text sized correctly?
Set the text height in the style (for example 0.125), then scale it using MLEADERSCALE.

What does it mean that multileaders are a hybrid?
They combine text behavior (style and height) and dimension behavior (scaled elements).

Do I need multiple multileader styles?
No. Use one style and let MLEADERSCALE handle scaling.

Why not create multiple styles for each scale?
It adds complexity and leads to inconsistent drawings.

How do I fix an existing multileader?
Use Properties and adjust the Overall Scale.

Do multileader styles carry over to new drawings?
No. They are stored inside each drawing file.

What is the most important thing to remember?
Set text height in the style, set MLEADERSCALE to the scale factor, and keep everything consistent.

Answer to Quick Check

B) Change MLEADERSCALE

Final System Summary

Here’s the full system:

Model Space = draw everything full size
Paper Space = your sheet

Viewports = control how the drawing appears

Scale factor = the number behind the scale

That same number is used everywhere:

• TEXTSIZE ? text
• DIMSCALE ? dimensions
• MLEADERSCALE ? multileaders

The Only Rule You Need to Remember

Draw everything full size in Model Space

Set your viewport scale in Paper Space

Use the same scale factor for all annotation

Final Thought

Once this system is set up correctly:

• You stop guessing
• You stop resizing things manually
• Your drawings become consistent and professional
