This is detailed within the Help concerning the fact that DRC ignores spacing rule violations for the first segment of connected nets leaving from the star point pad

Yes I know.... but it happens a very strange thing: if 2 tracks that join starpoint starts from a segment of the track an error is found (?!) , otherwise if they start from a pad or a via than there is no error . Why?

The DRC ignores the first segment from the starpoint to the first corner, at the corner DRC is back in action. So that I understand completely your points, please create a simple example design and send through to support.

The DRC was giving errors back as the star point rules were not being obeyed.

Move the first corner at the end of your first segment leaving the pad origin further than the spacing rules require.
