Three-Point Move

The DVTI_3pt Three-Point move is used when an "object" plane has to be moved to the plane of a "target" component by restricting its six degrees of freedom. The target plane is established by three points. The primary point on the object component moves to the primary point on the target component and the object aligns itself with the secondary and tertiary points of the target plane.

Example Model:

C:\Users\Public\Documents\DCS\3DCS_All Platforms_8_0_0_1\3DCS CAD & Example Models\Reference Models\Moves\Three Point move

 

Specification:

Object points        O1, O2, O3

Target points        T1, T2, T3

 

Description:

Three points O1, O2 and O3 are picked accordingly on the object component that is to be moved. These points constitute the three object points. The target points T1, T2 and T3 are then picked on the target component, respectively. The steps in the move sequence from the object points to the target points are outlined below.

 

1.The object point O1 moves to the target point T1. This point is the point of rotation for the object.

2.The object component then rotates about target point  T1 until the line formed by object points O1 and O2 is collinear with the line formed by target points T1 and T2. This line forms the axis of rotation for the object component.

3.The object component then rotates about the axis of rotation formed by the line created from object points O1 and O2 until the object point O3 is on the plane of the target component created by target points T1, T2 and T3, making the object plane coplanar with the target plane.
