Angle rounding in sketch circular pattern

MSE_Mech_94 — Mon, 07 Jan 2019 21:02:44 GMT

I am attempting to produce a circular pattern of an arc in a sketch. I select the arc, the pattern center and enter the angle to fill an the number of copies. The pattern is produced but the angle filled is rounded up to the next higher even number (that is, 34.0033 deg is rounded to 36 deg).

I can't repro this:

Can you attach your file showing the error? (File|Export|Archive file *.f3d)

See attached for f3d file. It is the patterned sketch I've been trying to work with. The measured angular span of the arc segments is 36.003 deg. I used 34.004259 deg as the angle for the symmetric circular pattern (and 17 copies).

Thanks -

The pattern looks correct:

I see what I did - I counted the total angle spanned by all the arc segments (included the span of the last segment) instead of the total angle from the beginning of the first arc segment to the beginning of the last arc segment.

Problem solved!

All that education and experience and I still need help counting . . .

Thanks!
