Hi
Please see to attached picture.

I want to have a sin curve that be only in one direction not in both (- and + direction), in the Z axis but when i wrote it with ABS function, solid works doesn't do that and also solid works doesn't show any wrong letter too.

Can some one help me ?

Thanks

Look at the message in the yellow box. It says the curve could not be generated because it would be discontinuous. What you'll have to do is use a separate equation for each discontinuous section, with each having a different range for t. Or you could make a pattern of a single equation and use composite curve to join them.
