Form
The form of an inner thread is determined by its contour. It cannot be assigned a fill.
If you draw a new inner thread, its threaded bore - like an ellipse - is shown with standard pens Thick and Thin. The thread turns are drawn with the Thin pen. If the thread is not continuous, the last turn of the thread is drawn with the Thick pen.
In drawing mode, Arbortext IsoDraw displays the thread turns in schematic form only in order to accelerate the screen redraw process. In preview mode and in print the thread turns naturally appear in their correct form.
* 
The Thick and Thin pens and the spacing of the thread turns are assigned automatically. If other attributes are required, these can be converted on the Threads preferences panel. (See Preferences) If a special attribute is to be applied in an individual case, the thread must first be converted into individual elements (see Convert).
