TechDraw - Arc Center Marks visible in drawing/ vanished in pdf file

[maker]

Hi all,

In the TechDraw workbench I carried out a drawing with some bores. For the better visibility I've enabeled Arc Center Marks to show the muss of Börse in top respectively bottom view.
I've set in
Properties panel
|-> View panel
|-> Arc Center Marks --> true

After that they are shown correctly in the drawing in TechDraw.

Then I carry out the
PDF export
of the drawing.
In the PDF file the Arc Center Marks are vanished.

Same occurs if I try Print Preview.

Has anybody an idea what the reason for this strange behaviour is?

Kind regards

Use 0.19 and configure it in the TechDraw preferences.

Sorry, I 've forgotten to mention that I created the drawing with 0.19 Revision 22670.

@chrisb
Oh no, thanks very much for the hint!
In the TD preferences I've now found the annotations checkbox
for the midpoint printing.
