To Reposition a Grip in a Dynamic Block Definition

Click Drafting tab > Block panel > Block Editor.
In the Edit Block Definition dialog box, select the block whose grips you want to modify.
In the Block Editor drawing area, select a custom grip (not the standard grip associated with the key point of the parameter).
Do one of the following to reposition the grip:
- Drag the grip to another position in the block space.
- On the Properties Inspector, under Geometry, enter values for the Base X and Base Y properties. (These values are relative to the base point of the parameter.)
Click Block Editor visor > Save.
Click Block Editor visor > Exit.
