Applying EntityGrip Nodes
EntityGrips (EGrips) are selectable handles displayed as small squares at the end points, centers, vertices, insertion points, and other geometric points of solids.
Every solid displays some EntityGrips after selection. You can edit the solids by dragging them. Their shape specifies how the EGrip changes the solid.
There are two types of EGrips:
 Corner EGrips (squares): modify the solid by stretching in any direction or change the location of the solid.
 Arrow EGrips (triangles): modify the solid by stretching the EGrip forward or backward.
When selected, EGrips change to red.
This table lists entities that have EGrips, where they are located, and the result of how the EGrips modify the entity.
