2 Morphing objects using OmniCAD NX 902

Morphing objects using OmniCAD

You can morph objects in the NX CAD environment using the following integrated OmniCAD

commands.

OmniFree Transformer

Use this command to morph objects using points and curves as constraints.

OmniMesh Transformer

Use this command to morph objects using CAE Meshes, STL files, or point clouds.

Note

Siemens PLM Software recommends that you use an NX facet body

instead of a JT facet body.

OmniCopy Transformer

Use this command to copy the parameters of the transformed objects and then

transform the objects by using the copied parameters.

Flow Blend Use this command to create constant or variable blends along complex faces that

have small curvature. These blends are easy to manufacture and increase product

durability and aesthetic appeal.

OmniSwitch Application

Use this command to export NX objects that you want to transform into the

OmniCAD software.

Save OCP File

Use this command to export NX objects that you want to transform into the

selected OmniCAD part file and then save the selected OmniCAD part file.

Note

Make sure that the environment variable $OmniCAD_NX90_DIR is available in the

\ugii\menus\custom_dirs.dat file. If this environment variable is not available, copy the

\ugii\menus\custom_dirs.dat file to your local drive, add the environment variable

$OmniCAD_NX90_DIR to it, and then set the environment variable UGII_CUSTOM_DIRECTORY_FILE

to \custom_dirs.dat

Where do I find it?

OmniFree Transformer dialog box

Product Shape

Select Entity Lets you select objects that you want to transform.

Fixed Curve

Select Curve Lets you select the curves that do not change during

transformation.

Continuity Lets you specify continuity.

Add New Set Lets you add a new set of fixed curves.

Transformation Curves

Select Start Curve Lets you select the start curve for the

transformation.

Select End Curve Lets you select the end curve for the transformation.

Continuity Lets you specify continuity.

Note

The continuity of all the objects that are

involved in the transformation retain the

continuity of the original objects.

Align Break Points Aligns break points of the start curve with the end curve.

Reverse Curve Direction Reverses the direction of the transformation.

Reverse Tangent Direction Available when Continuity is set to G1 or G2.

Reverses the tangent direction.

Add New Set Lets you add a new set of transformation curves.

Transformation Points

Specify Start Point Lets you select a start point for the transformation.

Specify End Point Lets you select an end point for the transformation.

Free 2D

Free 2D Transforms the objects in the X and Y directions only. The Z direction remains unchanged.

To specify a plane, use the Specify Plane options.

Settings

Hide Original Hides the previously selected objects.

Apply Original Attributes Applies the same attributes of the original objects, such as color, line, or font to the selected objects.

Step Sets the density of points along fixed and transformation curves.

Distance Tolerance Sets the distance tolerance for the transformation.

Preview

Show Transform Vector Displays the transformation points in the graphics window. You can use the points to verify the

transformation path.

OmniMesh Transformer dialog box

Product Shape

Select Entity Lets you select objects that you want to transform.

Meshes

Meshes Topology Aligned

The mesh elements are topologically the same.

Unaligned

The mesh elements are not topologically the same.

NX calculates the alignment of two mesh elements

and transforms the objects.

End Only (WLS)

The mesh elements are available only for the end

facet body. NX uses the WLS (White Light

Scanning) method to transform the objects.

Select Start Facet Body Available when the Mesh Topology is set to Aligned or Unaligned.

Lets you select the starting facet body.

Select End Facet Body Lets you select the ending facet body.

Settings

Hide Original Hides the previously selected objects.

Apply Original Attributes Applies the attributes of the original objects, such as color, line, font to the selected objects.

Continuity Lets you specify the continuity.

C2 (Curvature)

Transforms objects faster.

C4

Transforms objects more slowly than the C2 (Curvature) option but produces better transformation quality.

Transformation Factor Lets you set the deformation value.

Smoothing Lets you specify smoothness for the transforming objects.

Note

For class A models, set the Smoothing list to either High or Very High.

Step Count Lets you specify the number of steps to use to transform the objects. If you specify more steps, the

transformation results are more accurate.

Distance Tolerance Sets the distance tolerance for the transformation.

Preview

Show Transform Vector Displays the transformation points in the graphics window. You can use these points to verify the

transformation path.

OmniCopy Transformer dialog box

Product Shape

Select Entity Lets you select objects that you want to transform.

Reference Entity

Select Transformed Entity Lets you select transformed objects that you want to

copy.

Settings

Flow Blend dialog box

Edge to Blend

Select Edge Lets you select the edges that you want to blend.

Variable Radius Points

Specify Location Lets you specify points on the edges or adjacent

faces of edges to create blends that have a variable

radius.

You can enter a blend radius for the specified point

in the Radius box.

Radius Lets you set a blend radius for the specified point.

Smoothing Ranges

Specify Start Point Lets you specify a point from which you want to

start smoothing the blend.

Specify End Point Lets you specify a point at which you want to end

smoothing the blend.

Add New Set Lets you add new sets of smoothing ranges.

Settings

Trim input Faces Trims adjacent faces of the edge that forms the blend.

Distance Tolerance Sets the distance tolerance for the blend.

OmniSwitch Application dialog box

Export all Visible Entities Exports all visible NX objects that you want to transform into OmniCAD software.

Select Entity to Export Lets you select NX objects that you want to export

into OmniCAD software for transformation.

Select Entity to Export Lets you select and export NX objects into an

OmniCAD part file.

Select OCP File Lets you select the OmniCAD part file that you

want to save.
