Instruments not displaying from Reference file.

[CMarshall922]

Hello All, 

I am currently doing a clean up of a light plot for a production. The designer sent me his plot that has lots of data that I do not need in the final plot (Classes, Layers etc.) 
So I am referencing their file and redrawing over it only the details I need. 
The problem I am having is the reference viewport even tho all classes and all layers are full visibility the instruments are not showing up on the layer. Has anyone had this issue before or know a work around?

Are you sure the Classes and Layers are visible both in the Navigation palette and also under the Viewport Layers... and Classes... buttons?

Instead of referencing you could try importing just the layers that you need. In the layers tab of the organisation window select new layer then choose the file you wish to import the layer from.  Be sure to check import layer objects and click OK. I tend to reference any source geometry/venue outlines. IMO Anything with Data I prefer  to have it in the actual file just in case (you don't have to do this). If you are referencing be sure to check the cache option in the referencing preferences.
