You can calculate the projected area of the reference model to help calculate the clamping force needed to keep a mold set closed during operation.

• Specify the entity.

• Specify the projection direction.

• Projected area is calculated.

You can calculate the projected area of the reference model to help calculate the clamping force needed to keep a mold set closed during operation. To calculate the projected area, you can click Projected Area Analysis group. This opens the Measure dialog box.

In the Measure dialog box, you must specify the following items:

• Entity – Specifies the entity that is to be projected. You can select the following entity types:

– All Ref Parts – This is the default Entity selection.

– Surface

– Quilt

– Facets

• Projection Direction – Specifies the direction that the Entity is projected.

You can specify any of the following projection direction references:

– Default Pull Direction – This is the default Projection Direction.

– None

– Plane – Enables you to select a plane that the direction is perpendicular to.

– Line/Axis – Enables you to select a line or axis as the direction.

– Coordinate System – Enables you to select a coordinate system. Once you select the coordinate system, you must specify which coordinate

axis defines the direction.

– View Plane – Uses the current viewing plane as the projection reference.

Once you have defined the entity and projection direction, you can click Compute to calculate the projected area of the entity. The selected entity is projected onto an imaginary plane that is perpendicular to the projection reference, as shown in Figure 2. The area of this projection is calculated
