Datum Feature Symbol Help

[navyhill]

I am fairly new to Pro/E and I am having trouble figuring out the process for getting reference datums to display in my drawings. I have defined two datums in my model. A datum plane "A" on one end of a cylindrical part and a datum axis "B" through the centerline of the cylinder. The datum feature symbol displays in the model correctly on their respective datums. When I go to the drawing, the datum "A" is correctly shown on the drawing view, but the datum "B" is not showing up. I have tried inserting every possible view, along with Show/Erase > show all - to try to get Pro/E to display all datums, to no avail. Does someone have a nice little tutorial or some helpful hints on this? Thanks!

Suggest you ask in the Pro E forum.

Although, at least to ASME stds you can't make the center-line the datum feature, it needs to be the feature that the axis is derived from.

Parts do not have centerlines, you can't put the datum symbol on the centerline, pls ref the the link below.

If you feel it is necessary to label a centerline as a datum, you need to prefix it with "CL" or "AXIS", thus defining the line as the centerline or axis of datum B. This should be considered a reference label and you also need to define it elsewhere on the feature. As noted, simply labeling a line as a datum is not per the standard.
