In this error, notice ORCHID_FAUCET__HOLE_15″ on line 3. The ” is an invalid character in all CAD software and because the ” is used in the color name, your CAD software cannot open that file.

Invalid Characters are < > / \ ” : ? | , = ` ( ) .

To correct this problem:

  1. Open the .dxf file in the LT-55 XL software.
  2. Click Color and change the color name by removing all invalid characters i.e. < > / \ ” : ? | , = ` ( ) .
  3. Close the color menu.
  4. Save the file.
  5. Open the .dxf file in your CAD software.

Valid characters that may be used in your layer/color names:

  • A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
  • a b c d e f g h i j k l m n o p q r s t u v w x y z
