Source and Target LCS of 3D Transformations

When transforming 3D Fragments source and target local coordinates systems (LCS) can be specified. Source LCS is attached to transformed fragment. Target LCS is defined independently of transformed fragment.

At first, the Transformations command aligns source LCS to target LCS. Then user can define Transformations in relation to new position and orientation of source LCS.

Selected Source LCS and Target LCS are displayed in the corresponding fields in the upper area of the Main Transformations tab of the Parameters window.

Transformations are divided into groups, which are displayed in the list in the lower area of the Main Transformations tab of the Parameters window.

Content of the currently selected group is displayed in the Transformations tab of the Parameters window.

When transforming operations and constructions, source LCS is the only available. In this case aligning source LCS to an arbitrary selected existing LCS can be performed by creating a special kind of transformation  - Coordinate System and subsequently deleting automatically created elementary transformations, instead of selecting a target LCS.

Source LCS

Source LCS is displayed in the drop-down in the Main Transformations tab of the Parameters window.

Content of the drop-down depends on the object of transformation

When transforming operations and constructions following options are available:

•Global LCS of the document

•LCS in the Bound box center
Axes orientation in this case coincides with the Global LCS

•Fixing by LCS
Can be created using Select or Create Source LCS automenu option of the Transformations command.

When transforming 3D fragments following options are available:

•Attachment by default
(Global LCS),

•One of the LCSes existing in the transformed fragment
Drop-down will contain all of the LCSes available in the transformed fragment

•Fixing by Fragment
Can be created using Select or Create Source LCS automenu option of the Transformations command. .

 

 

LCS for Fixing by LCS or Fixing by Fragment options can be defined using the following automenu option:

Selecting this option switches the system into LCS defining mode.

Target LCS

Target LCS is displayed in the Main Transformations tab of the Parameters window when transforming 3D fragments.

If a target LCS was selected during insertion of a fragment into an assembly, it will be selected while using the Transformations command as well.

If a target LCS was not selected during insertion of a fragment into an assembly, the Target LCS field will contain <None> value.

Selecting target LCS can be performed using the following automenu option:

Clearing the target LCS selection can be performed using the following automenu option:
