====================================================

1/ Command :

• SQA, SQW, SQX, SQY, SQZ : Surface Quality A, W, X, Y, Z

2/ Description :
This tool allows you to quickly draw surface roughness symbols (A, W, X, Y, Z) in mechanical drawings.

• Multiple Commands: Each command corresponds to a specific surface roughness grade (e.g., SQA for grade A, SQW for grade W, etc.).

• Snap Functionality: The command automatically activates the NEAR OSNAP to help place the symbol directly on an object line.

• Compatibility: This is a dedicated CADian Lisp tool and works only within CADian.

3/ How to Use :

1. Type one of the commands (sqa, sqw, sqx, sqy, or sqz) in the command line and press Enter.

2. Click the Object Line where you want to place the symbol (Near Osnap is active).

3. Click a point to define the Direction (e.g., clicking to the right for a horizontal line usually orients it correctly).

4. Enter the Length of One Side of the Triangle (symbol size) and press Enter.

5. The corresponding surface roughness symbol is drawn at the　selected location and orientation.
