Footprint Expert reports the length of the lines forming the cross as the maximum value. Most CAD programs do not account for round ends when reporting the length of the lines. If you subtract the width (0.050) from the length reported by Footprint Expert (1.016), you get the result reported by Altium Designer (0.966).

I created a Silkscreen Plus + symbol in Footprint Expert 1.00 mm X 0.15 mm line width.
Here is the Footprint Expert Symbol dialog box:  I translated the footprint to Altium and here are the Plus Symbol dimensions.  Here is the Altium Properties for the Polarity Marker:  It seems to be working 100% correct. Can you confirm that the issue you reported is working correctly? |
