This is a nice solution for copying co=F6rdinate sytems using the transform measurement as offset: It assumes there is at least one common coordinate system in your assemblies and a coordinate system which you want to copy.
In the base assembly. Got to Analysis -> Measure -> Transform Perform a measurement between the common coordinate system and the target coordinate system. (be aware to select the common one first) When the measure results appear, click on the blue i button. A Information windows with location data appears, in this window choose File -> save as... Save the .trf result file in a convenient location like the working directory. The location data is stored now and will stay stored till the file is overwritten or deleted.
Go to your target assembly. Make a new coordinate system. Select the common coordinate system as starting reference. Change offset type to =91from file=92. Select the .trf file created before. The new coordinate system will be placed with the exact displacement and angle from the base point as the coordinate system measured before.
The function is handy in different situations, but kinda hidden like PTC themselfs have forgotten it exists.
Please let me now if this method is what you where looking for. Joost.
