When you enter text into your drawing, the current text style determines the text font, size, angle, orientation, and other text characteristics.
All text in a drawing has a text style associated with it. When you enter text, the program uses the current text style.
You can assign a text font as part of the text style definition. Several factors depend on the type of text you are working with.
Text height determines the size in drawing units of the letters in the font you are using.
The obliquing angle determines the forward or backward slant of the text. The angle represents the offset from 90 degrees.
Text can be vertical or horizontal. Text can have a vertical orientation only if the associated font supports dual orientation.
