One annoying thing i have found in Creo 2.0 is related to sketching sections for blend....if we change the default orientation while sketching the first section....then the orientation for the subsequent section doesnot take the orientation of the first as a result of which we have to cancel everything and sketch the section in default orientation only...can something be done regarding this?
Try creating the subsequent sketch planes based on the 1st. That way at least they remain parallel. If you change the rotational orientation of the 1st, then you also want to use the same references for the subsequent sketches.
