If you use the function TrnSetScale to set all the scales on a trend at once, the function will not set any of the scales. For example if you call as follows TrnSetScale(40,-1,-1,0) has no effect on the trend when executed. When the same function is called for individual pens (eg. TrnSetScale(40,2,-1,0) it works perfectly.

CIT has confirmed this to be a problem in Citect for Windows versions 1.00 to 2.01. This problem has been fixed in version 2.10 and later.


You may work around this problem by setting each pen individually or by upgrading to version 2.10 and later.
