MNF and MD DB Transformation
Bodies tab → Flexible Bodies container → MNF Xform 
or
(Classic) Build → Flexible Bodies → XForm
It performs transformation on an already existing flexible body or Modal Neutral File (MNF) or MD DB File (.MASTER). The types of transformation operations that can be performed are:
■Translation - Translate along a vector, by specified distance.
■Rotation - Rotate about an axis, by specified angle.
■Mirroring - Mirror about a plane.
For the option: | Do the following: |
|---|---|
Flexible Body Name/MNF File/MD DB | Select either: ■Flexible Body Name, and then select a flexible body that already exists. ■MNF File, and then select the name of the MNF to import. ■MD DB, and then select the name of the MD DB to import. Tips on Entering File Names in Text Boxes. |
Index | The parameter applies only, when you select MD DB file. The parameter specifies the index of the flexible body in the specified MD DB. The parameter is optional. Default value is 1. Note: You can view all the flexible bodies in the MD DB, using the “…” button provided beside the Index. The desired flexible body can be selected by double-clicking on the displayed list. |
MNF/MD DB | Select the appropriate option for Output File and enter the name of the MNF or the MD DB file. |
Create Flexible Body... | Select to open Create a Flexible Body dialog box after the intended transformation is carried out, so that you can create the flexible body and see the transformation. |
Mirror | Select to perform mirroring operation. You need to specify mirroring plane to perform mirroring operation. |
Translate | Select to perform translation operation. You need to specify a direction for translation and a distance to translate. |
Rotate | Select to perform rotation operation. You need to specify the axis about which rotation can be done and an angle for rotation. |
If Mirror option is selected, following options are available. | |
Plane Normal to Vector/ Plane From 3 Points/ Plane Normal to 2 Points | Specify either of these three methods to specify the mirroring plane: ■Plane Normal to Vector - This option allows you to specify a vector which is normal to the plane about which you want to mirror the flexible body. ■Plane From 3 Points - This option allows you to specify three points to define the mirroring plane. ■Plane Normal to 2 Points - This option allows you to specify 2 points which define a vector normal to the plane about which you want to mirror the flexible body. |
If Plane Normal to Vector is selected, following options are available. | |
Direction | Direction can be one of the following: ■Global X - This option specifies that the mirror plane is normal to the global X axis. ■Global Y - This option specifies that the mirror plane is normal to the global Y axis. ■Global Z - This option specifies that the mirror plane is normal to the global Z axis. ■X axis of Marker - This option specifies that the mirror plane is normal to the specified Marker's X axis. ■Y axis of Marker - This option specifies that the mirror plane is normal to the specified Marker's Y axis. ■Z axis of Marker - This option specifies that the mirror plane is normal to the specified Marker's Z axis. ■User Defined - This option specifies the mirror plane is normal to the user entered vector. |
Marker | Only available if Direction is either X Axis, Y Axis or Z Axis of Marker. Mirroring will be done with respect to marker's orientations (X Axis, Y Axis or Z Axis) respectively. |

From Location, To Location | Enter the coordinates of two end points of a vector that is normal to the mirroring plane. |
If Translate option is selected, the following options are available. | |
Direction From Vector/ Direction Normal to 3 Points/ Direction From 2 Points | Specify either of these three methods to define the direction of translation: ■Direction From Vector - direction is specified as a vector. ■Direction Normal to 3 Points - direction is specified as normal to a plane. ■Direction From 2 Points - direction is specified by two end points of a vector. |
If Direction From Vector option is selected, the following options will be available. | |
Direction | Direction can be one of the following: ■Global X - This option translates the flexible body in the direction of global X axis. ■Global Y - This option translates the flexible body in the direction of global Y axis. ■Global Z - This option translates the flexible body in the direction of global Z axis. ■X axis of Marker - This option translates the flexible body in the direction of the specified Marker's X axis. ■Y axis of Marker - This option translates the flexible body in the direction of the specified Marker's Y axis. ■Z axis of Marker - This option translates the flexible body in the direction of the specified Marker's Z axis. ■User Defined - This option translates the flexible body in the specified direction. |
Marker | Only available if Direction is either X Axis, Y Axis or Z Axis of Marker. Translation will be done with respect to marker's orientation (X Axis, Y Axis or Z Axis) respectively. |
Direction Vector | Only available if Direction is User Defined. |
If Direction Normal to 3 Points option is selected, the following options will be available. | |
Point 1, Point 2, Point3 | Specify the coordinates of three points that define a plane. Translation will be performed in the direction which is normal to the plane. |
If Direction From 2 Points option is selected, the following options will be available. | |
From Location, To Location | Enter the coordinates of two end points; translation will be done in the direction of the two end points. |
Distance | Enter the distance for translation of the flexible body. Except for the Direction From 2 Points option you are required to specify a value for Distance. For Direction From 2 Points option, if Distance is not specified it is calculated to be the distance between the two points. |
If Rotate option is selected, following options will be available. | |
Direction From Vector/ Direction Normal to 3 Points/ Direction From 2 Points | Specify either of these three methods to specify an axis of rotation: ■Direction From Vector - rotation axis is defined as a vector. ■Direction Normal to 3 Points - rotation axis is defined as a plane normal. ■Direction From 2 Points - rotation axis is defined by two end points. |
If Direction From Vector option is selected, the following options are available. | |
Direction | Direction either can be ■Global X - The rotation axis is parallel to the global X axis. ■Global Y - The rotation axis is parallel to the global Y axis. ■Global Z - The rotation axis is parallel to the global Z axis. ■X axis of Marker - The rotation axis is parallel to the specified Marker's X axis. ■Y axis of Marker - The rotation axis is parallel to the specified Marker's Y axis. ■Z axis of Marker - The rotation axis is parallel to the specified Marker's Z axis. ■User Defined - The rotation axis is parallel to the user specified vector.. |
Marker | Only available if Direction is either X Axis, Y Axis or Z Axis of Marker. Rotation will be done with respect to marker's orientation (X Axis, Y Axis or Z Axis) respectively. |
Direction Vector | Only available if Direction is User Defined. |
Center of rotation | Enter the coordinates for the center of rotation. |
If Direction Normal to 3 Points option is selected, the following options are available. | |
Point 1 (center of rotation), Point 2, Point3 | Enter the coordinates of the three points that define a plane; rotation will be done about the axis which is normal to the plane, using Point 1 as the center of rotation. |
If Direction From 2 Points option is selected, the following options are available. | |
From Location, To Location | Enter the coordinates of end points; the end points define the axis for rotation. |
Angle | Enter the angle for rotation of the flexible body. |
Node Offset/ New Interface IDs | This option allows you to offset all the node IDs or to specify new interface IDs of the flexible body. This option is common for all the transformation options (that is, Mirroring, Translation and Rotation). ■Node Offset - Enter a value to offset all the node IDs. ■New Interface IDs - Enter new interface IDs for the current interface node IDs. Here the number of interface node ids entered have to be less than or equal to current interface node IDs of the flexible body. |
If you check the More option following parameter will appear. | |
MNF Write Options | This option optimizes the MNF through Adams Flex toolkit. It corresponds to the parameters in the MDI_MNFWRITE_OPTIONS environment variable. For more information on the MDI_MNFWRITE_OPTIONS, see Setting Up Translation Options through the MNF Toolkit. |
