custom object not imported same size as created

[MemeGtr]

I decided to make a steel truss (without trussmaker), made it with slanted beams and columns using standard steel profiles. even added some connection plates using morphs. Grouped it with some hotspots, 

saved selection as object, named it, imported it to a new file, everything seemed fine.

except that when it was actually in place in the drawing, it was shorter!

I measured everything again and the measurements are correct, but my truss is not placed with the correct size.

did I missed something ?

Open the object and delete the MUL commands at the start, else your object will scale based on your A and B inputs, which in this case did not match your original values.
