Analysis Modeling > Moves > Types of Moves

3DCS contains many move routines to give users the ability to model a large range of assembly processes. This document divides move routines groups based on frequency of use and briefly defines the routines.

Move Types	Descriptions
Step Plane Move	A 3-2-1 locating move. Requires all primary locators to be parallel but allows a "step" (offset) between them. Requires both secondary locators to be parallel but allows a "step" (offset) between them. Can automatically calculate perpendicular vectors for the primary, secondary, and tertiary planes.
Six-Plane Move	A 3-2-1 locating move. Uses a different plane to restrict each degree of freedom, therefore the primary locators can be non-parallel and the secondary locators can be non-parallel. A Six-Plane move can duplicate many other move routines, such as the Step Plane move.
Best-Fit Move	The Best-Fit move is similar to the Six-Plane move except that it can have more than six pairs of locators defined. Like the Six-Plane move, each pair of locators needs a direction defined. Then, each object feature is best-fit to each target plane. Each target plane is defined by the target feature and the direction.
Feature Move	Create Primary, Secondary, and Tertiary planes through selected features and then aligns the planes on the object part to the target part.
Pattern Move	Floats a part on a set of parallel hole-pin pairs. Used with over-constrained assembly parts.
Two Point Move	Aligns a part on a line or axis. Only defines 5 degrees of freedom. Used with radial symmetric parts, such as placing a long pin in a hole.
Three Point Move	A 3-2-1 locating move. Three points form the Primary Plane, the first two points also define the Secondary plane, and the first point is also the Tertiary locator.
Match Move	Rotates a part around an axis. Will set a gap to a target.
Thermal Scaling	Thermal Scaling move is designed to apply linear expansion or contraction to parts based on the Coefficient of Thermal Expansion (CTE) and the change in temperature
User DLL Move	Allows the user to link a separate move routine in a DLL file to 3DCS. 3DCS includes several DLL files with separate move routines. Please see the Add-In DLLs and Extra DLLs Sections for descriptions.
Iteration Move	A powerful, complex move with various modes. This move can translate parts, rotate parts, repeat a series of moves until a measure is in-spec, or re-float a move.
Pattern-Fit Move	The Pattern-Fit move is designed to rearrange multiple parts relative to the fixed parts and relative to each other, by using hole/pin Hole Sets and point to point Constraint Pairs.
Transform move	The purpose of the Transform move is to allow parts or features/points to be translated or rotated by a specific amount. This amount can be a specified as a constant value, a random value, or a calculated value from a measurement.
Autobend	The purpose of the Auto Bend move is to handle components and assemblies that are over-constrained on the primary plane, using some automated rigid-body methods.
R-Touch Move	Rotates a part around an axis. Will touch one point of a set to a target.
Rotate Line Move	Rotates a part around an axis. Will set two lines parallel.
Gravity Move	Floats a part on hole-pin pairs in a specified direction.
Least Square Axis Move	Uses two points to find the least squares axis through a group of points.
Line-Plane Move	Is a type of move used when a part has to be moved to a plane and controlled on the plane by the intersection of a line and the plane and another point on the plane.
