How to Add Surface Finish Symbol in AutoCAD Quickly

To add a surface finish symbol in AutoCAD, use the SURFTR tool found under the Annotate tab or type SURFTR in the command line. You can also insert the symbol manually by typing the Unicode character ⌵ or using the MTEXT command with the appropriate symbol font.

Syntax

The main command to add a surface finish symbol is SURFTR. This opens the Surface Texture dialog where you can specify the symbol type, lay direction, and other parameters.

• SURFTR: Command to start the Surface Texture tool.
• Symbol Type: Choose the surface finish symbol style (e.g., roughness, machining).
• Lay Direction: Direction of surface texture lines.
• Text: Optional text to add with the symbol.

Output

Opens Surface Texture dialog for symbol insertion

Example

This example shows how to add a basic surface finish symbol using the command line and dialog.

autocad

Type SURFTR and press Enter
In the Surface Texture dialog:
- Select the desired symbol (e.g., basic roughness)
- Set lay direction if needed
- Click OK
Place the symbol on your drawing where required.

Output

Surface finish symbol appears at the chosen location on the drawing

Common Pitfalls

• Not using the SURFTR command and trying to type the symbol manually without the correct font or Unicode can cause display issues.
• Placing the symbol without setting the correct scale or orientation may make it hard to read.
• For manual text insertion, forgetting to use the correct Unicode character ⌵ (U+2305) or symbol font leads to missing or wrong symbols.

Wrong way:
Type MTEXT and enter "Surface Finish" without symbol

Right way:
Type MTEXT and enter "\U+2305" or insert symbol from Symbol dialog

Output

Wrong way: No symbol shown
Right way: Surface finish symbol displayed correctly

Quick Reference

Use this cheat sheet to quickly add surface finish symbols:

Action	Command/Method	Notes
Open Surface Texture tool	SURFTR	Use command line or Annotate tab
Insert symbol manually	MTEXT + Unicode ⌵ (U+2305)	Requires correct font support
Set lay direction	Surface Texture dialog	Controls symbol orientation
Adjust scale	Properties panel	Ensure symbol fits drawing scale

Key Takeaways

Use the SURFTR command to add surface finish symbols easily with the dialog.

Manual insertion requires the Unicode symbol ⌵ (U+2305) and proper font support.

Always check symbol scale and orientation for clear visibility.

Avoid typing symbols without correct fonts to prevent display errors.
