Sets the current text style to SIMPLEX.
Summary
This style usually uses the AutoCAD compiled shape (SHX) font Simplex. Any text you add using the MTEXT and DTEXT commands default to simplex thereafter. If you use the AMTEXT3, AMTEXT5 or AMTEXT7 command before using the MTEXT or DTEXT command, the text style resets to STANDARD and the effect of the AMSTYLESIMP command is discarded.
