Summary:
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.

 

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