I am needing to test a DWG contains certain features for example a north point. If the drawing contains the layer that the north point is on I can use a range of functions to test if it exists i.e. tester, statisticsCalcultaor, etc
Â
But what if the north point is missing and therefore there is nothing on that layer, how do you test for its non-existence?
Â
Use a Creator transformer to create a dummy object.
Attach an AttributeCreator to create an attribute Layer with the value of the DWG layer for the North point.
Then use a FeatureMerger to merge dummy object (as supplier) to the data from the DWG.
If the supplier is unused, the North point layer does not exist.
Hope this helps.

Thanks @erik_jan that should work perfectly.
