How to prevent text from mirroring inside a mirrored block

Symptoms

Even though the MIRRTEXT system variable is set to 0, the text is mirrored when you mirror a block that contains text.

Cause

When the MIRRTEXT system variable is set to 0, text created with TEXT, MTEXT, and ATTDEF commands are not mirrored. However, if blocks contain text or mtext entities or constant attributes, they are mirrored.

Note: MIRRTEXT only affects text or mtext entities, but not text or mtext entities in blocks.

Solution

Instead of using your text as text, include it as an attribute in the block. This can be done with the ATTDEF command. If the MIRRTEXT system variable is set to 0 and an attribute within a block is not Constant, the attribute text is not mirrored when the block is mirrored.

Note: Make sure the Constant option under the Attribute Flags section of the Define Attribute dialog box is not selected in order to stop the attribute text from being mirrored. You can also see the Constant option under Misc in the Properties panel, when you select the attribute.
