A diesel expression in AutoCAD is an essential tool that allows users to control the appearance of text within their drawings. By using this feature, you can enhance the visual representation of your text elements and make them stand out in your designs.
Understanding Diesel Expressions
Diesel expressions are dynamic text strings that can be used to define the content, formatting, and properties of text objects in AutoCAD. They offer a powerful way to create customized annotations within your drawings. With diesel expressions, you can incorporate variables, functions, and operators to generate dynamic text based on various parameters.
Benefits of Diesel Expressions
Using diesel expressions in AutoCAD provides several benefits:
1. Dynamic Text: Diesel expressions enable you to create dynamic text that updates automatically based on changes in your drawing. This helps save time and effort by eliminating the need for manual updates.
2. Customized Formatting: With diesel expressions, you have complete control over the formatting of your text. You can apply bold, italics, underline, or other styles to specific portions of the text string using HTML-like tags.
3. Conditional Statements: Diesel expressions support conditional statements such as IF-THEN-ELSE and CASE statements. This allows you to display different text or modify its appearance based on certain conditions or criteria.
4. Data Extraction: By combining diesel expressions with AutoCAD’s data extraction tools, you can extract information from your drawing database and incorporate it into your annotations automatically.

Using Diesel Expressions
-
Create a Text Object:

Edit the Text:
-
Apply Diesel Expression:
-
Use Formatting Tags:
To use a diesel expression in AutoCAD, follow these steps:
Start by creating a text object using the TEXT command or any other method available in AutoCAD for adding text elements.
Double-click on the text object to enter the text editing mode. Here, you can modify the content and formatting of the text.
To apply a diesel expression, enclose it within curly braces “{ }” within the text string. For example, {<C0.7>This is a diesel expression} will display the text “This is a diesel expression” with a font size of 0.7.
To apply formatting to specific portions of the text, use HTML-like tags within the diesel expression.7>This is <b>bold</b> text} will display “This is bold text” with a font size of 0.
Examples of Diesel Expressions
Here are some examples of diesel expressions that can be used in AutoCAD:
1. Date and Time: {<$DATE\nMM-dd-yyyy>} – Displays the current date in MM-dd-yyyy format. 2.
Incrementing Numbers: {<$SEQNO>} – Displays an incrementing number for each occurrence of the text object. 3. Conditional Text: {<$IF(&&, >, , )>} – Displays different texts based on predefined conditions.
Remember, diesel expressions are case-sensitive, so ensure you use proper uppercase and lowercase letters for commands and variables.
In conclusion, diesel expressions in AutoCAD offer immense flexibility in creating dynamic and visually appealing annotations within your drawings. By mastering this feature and utilizing its capabilities effectively, you can enhance the clarity and readability of your designs while reducing manual effort. So, start using diesel expressions in your AutoCAD projects and take your annotations to the next level!
