GGU-CAD: Post-editing text
The following dialog box opens if a text object is clicked:

Beside the change in the drawing sequence described under lines, both the text entered and the font, writing angle, font colour and font size can be altered. In addition, the background can be deleted so that the text is also easily visible, in front of coloured areas, for example. If this check box is activated the text is displayed on a white rectangle.
