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.

EntityGrip Nodes and Editing Results

Entity	Location	Result
Box	Base center	Moves the box
	Four base corners	Modifies the length and width of the box
	Base midpoints (arrow EGrips)	Modifies the length and width of the box in the direction of the arrow
	Top and bottom (arrow EGrips)	Modifies the height of the box in the direction of the arrow
Wedge	Base center	Moves the wedge
	Four base corners	Modifies the length and the width of the wedge base
	Base midpoints (arrow EGrips)	Modifies the length and width of the wedge base in the direction of the arrow
	Top and bottom (arrow EGrips)	Modifies the height of the wedge in the direction of the arrow
Pyramid	Base center	Moves the pyramid
	Base corners, Base midpoints	Modifies corners and sides uniformly. Note: You cannot modify one corner or one side individually.
	Top point (apex EGrip)	Modifies the height of the pyramid
	Top point (radius EGrip)	Modifies the pyramid shape (truncated pyramid)
	Note: You cannot modify the number of sides using EGrips. Use the Properties palette to specify any number of sides.
Sphere	Center	Moves the sphere
	Four circumference points	Modifies the diameter of the sphere
Cone	Base center	Moves the cone

	Top point (radius EGrip)	Modifies the cone shape (truncated cone)
	Four circumference points	Modifies the base radius of the cone
	Bottom arrow EGrip	Modifies the height of the cone in the direction of the arrow
Cylinder	Base center	Moves the cylinder
	Four circumference points	Modifies base radius of the cylinder
	Top and bottom (arrow EGrip)	Modifies the height of the cylinder in the direction of the arrow
Torus	Center	Moves the torus
	Section center (arrow EGrip)	Modifies the radius of the torus
	Four circumference points	Modify the radius of the tube
