and select the required reference.| | • You can add any number of planar references. However, for view clipping, define a zone using a maximum of six planar references. • In Assembly, if you change the reference type after specifying some references, those references are no longer displayed. If you revert to the earlier reference type, the references reappear. • Click  to remove a reference at any time. |
5. If you specify more than one reference, click AND or OR.
