How to create or show radial / bolt circle axis?

Greetings:

How do you create a radial or bolt circle axis in Catia v5r17 sp3?

Thanks,

If the pattern is positioned around a center hole, I use the "Centerline with Reference" command. First select one of the circles of the bolt hole pattern, then select the center hole. You should now have a center mark that consists of an angled line that points towards the center of the pattern and an radial arc that is the bolt circle arc portion.

Now you must manually drag the center axis around the bolt hole pattern. To do so without extending the angled line portion of the center mark, do the following.
Click on the center mark that was created, then press and hold the control key, while dragging one end of the center mark.
If you want the angle portion of the center mark on each hole, you must create each separately.

Thank you much for your tip.

Can this be done without creating the center hole? In other word, can the radial hole pattern be created with a centerline of a circular boss and a plane?

Not only the pattern has to be positioned around a center holes, it seems to require a lot of effort to create a radial circle axis in Catia. It is much easier in Pro/E Wildfire. Just need to create a radial pattern hole feature and set a radial_pattern_axis_circle parameter to yes. There is no need for a center hole.

There doesn't need to be a center hole, but there needs to be circular geometry (Whether a hole or a boss) to use as a reference in your drawing view. I don't believe you can use a center axis, but I could be wrong.

Catia definitely has its weaknesses in the drafting workbench.
