Analyzing Reference Model Orientation

You can modify the orientation of the reference model in the
mold model.
• The system lines up
coordinate systems from
the reference model and
mold model.
• Modify reference model
orientation:
– Standard
♦ Select a coordinate
system.
– Dynamic
♦ Modify orientation of
REF_ORIGIN.
• Other dynamic options:
– Projected area
– Draft check
– Bounding box

Analyzing Reference Model Orientation
You can modify the orientation of the reference model in the mold model.
When you select the reference model to be added to the mold model, the
system selects a coordinate system from the reference model and assembles
it to a coordinate system from the mold model.
Modifying the Reference Model Orientation
You can modify the reference model orientation within the mold model either
by specifying a different mold layout coordinate system or by specifying a
different reference model coordinate system.
There are two different methods that you can use to specify a different
coordinate system in the reference model:
• Standard – Enables you to select a different, existing, coordinate system in
the reference model. A separate window opens that contains the reference
model, enabling you to select the coordinate system, as shown in Figure 1.
• Dynamic – A separate window opens that contains the reference model.
However, a new coordinate system called REF_ORIGIN is created in the
reference model, and you can dynamically reorient this coordinate system
so that it will line up properly with the mold layout coordinate system.
In the separate window that contains the reference model, the X, Y, and
Z-directions of the REF_ORIGIN coordinate system are displayed, and
the positive Z-direction is the same as the PULL DIRECTION in the
mold model. Also, the Parting Plane displays to show you a surface
perpendicular to the pull direction. Figure 2 shows the REF_ORIGIN
coordinate system orientation and Parting Plane and the resulting
orientation in the mold model.
You can dynamically adjust the coordinate system orientation in the
reference model window, and the parting plane also adjusts dynamically.
The following options are available for adjusting the REF_ORIGIN
coordinate system orientation:
– Rotate – Enables you to rotate the REF_ORIGIN coordinate system
about the X, Y, and Z axes, either by typing a value or by dragging
a slider.
– Translate – Enables you to translate the REF_ORIGIN coordinate
system in the X, Y, and Z directions, either by typing a value or by
dragging a slider.
– Move To Point – Enables you to move the REF_ORIGIN coordinate
system origin to a specified point in the reference model. There are
two options available:
♦ Selection – Enables you to select a vertex, datum point, or other
coordinate system as the new coordinate system origin.
♦ Model Center – Moves the coordinate system origin to the model
center.
– Align Axis – Enables you to align the X, Y, or Z Axis of the REF_ORIGIN
coordinate system to a specified datum plane, curve, edge, axis, or
other coordinate system.
Reference Model Dynamic Orientation Options
When you are dynamically reorienting the REF_ORIGIN coordinate system,
the following additional options are available within the Ref Model Orientation
dialog box:
• Projected Area – Determines the area projected onto the Parting Plane as
defined by current orientation of the reference model in the mold model.
The Projected Area is calculated based on the current orientation after
Update is clicked.
• Undo/Redo – Enables you to undo or redo the last action performed.
