The available standards for the trunnion base plate for the selected trunnion type are shown in the Avail. Standard list.

To make a particular standard available to the MDS designer, click on the item in the Avail. Standard list then click on the left arrow icon on the left side of the list. This transfers the item to the adjacent Standard list. Clicking on the right arrow reverses this action.

The MDS trunnion type will determine if one or more trunnion base plates are required as the default. The supplied MDS defaults will take account of this.
