This tutorial explains how to create center hole lines using the 
TechDraw Workbench with oriented holes.
By creating angles for holes it's not possible to use vertical or horizontal center lines (false/true) from the properties of the view. Helping lines and/or helping points are created for this necessity.
Proceeding
1. Setting center lines on holes:
There are some possibilities to create a center line for holes. At first the lines or points on the hole must be selected as shown below. Second, the following tools can be used from the toolbar to create the center line:
Above: created with 
which creates centerlines between 2 points
Above: created with 
which creates centerlines between 2 lines
In the associated Combo View dialog box select in the Tasks panel under Orientation "Aligned" for axes out of main axes. Extend By means the length of the center line beyond of the body line in the drawing. With Shift Horizontal and Shift Vertical the center line can move in horizontal or vertical direction, if is necessary. Style means the figure of center line.
Above: dialog box
The created center line can change. Select the center line and press the button or from the tool bar which you have created the center line. Delete the center line only with 
from the tool bar after selecting the center line.
2. Setting angles:
Quadrant points select with 
from the tool bar. Next select the points as show below and use 
from the tool bar to create the angle. Other succession create other angles.
Is there no catching point on the center line change "ISO count" in the properties.
