 **Note:** When first creating a beam the eRT app will auto calculate the smallest block that will fit the current aperture shape.

 **Note** Selecting a block size that is too small for the aperture shape will cause an error that will not allow the creation/saving of the beam until an appropriate size is selected.

 ===== Target Margin =====
-  * **Margin:** The value (in cm) of the margin around the target structure as projected to isocenter. A negative margin can be used to specify a contraction around the beam target while positive values will cause an expansion.

A negative margin can be used to specify a contraction around the beam target while positive values will cause an expansion. The default block target margin can be configured in the [[:electronrt:userguide:tutorials:all_tutorials#machine_settings|Site Configuration Machine Settings]].
 **Note:** The app will automatically recalculate and display changes to the block as the margin is edited.

+===== Primitive Shape =====
+Instead of using the geometric target, the user may use a primitive shape as the base block opening instead. The user can choose the shape (square, circle, rectangle, or oval) and the dimensions at isocenter.
