I am getting the error "The following problems with this material were detected: Not all mandatory references have been selected." when trying to save a material as Linear Elastic Orthotropic for the model type. I have tried filling out all the property fields, using dummy values for a few of the properties I am really not concerned with, such as thermal conductivity. I am at my wits end why it will not let me save it.

Also, it never lets me set the reference geometry, although the Solidworks help file indicates you should do this for each part. If I can get it to save, if I do not set the reference geometry, if I just make sure to build my part to match the properties entered, will that work correctly? The application is wood, and the parts are simple enough to build them in the correct orientation.
