About the Swept Blend User Interface
The Swept Blend tab consists of commands, tabs, and shortcut menus. Click Model > Swept Blend to open the Swept Blend tab.
—Creates a solid feature.
—Creates a surface feature.
—Removes material along the swept blend to create a cut for a solid feature or a quilt trim for a surface feature.
—Flips the remove functionality to remove material from the opposite side of the sketch.
—Adds a thickness to a sketch to create a thin solid, a thin solid cut, or a thin surface trim. This option is not available for Swept Blends created from selected sections.
Thickness box—Sets a thickness value.
—Switches the thicken direction between one side, the other side, or both sides of the sketch.
Quilt collector—Displays a quilt to trim when and are selected.
—Toggles between two sides of a quilt to specify which side retains the quilt ID when you keep both sides of the quilt in a trim operation.
Trajectories table
Trajectories—Displays up to two chains as trajectories for the swept blend, and sets trajectory type.
X—Sets trajectory as an x-trajectory.
N—Sets trajectory as a normal trajectory. Sections are normal to the trajectory with the N check box selected.
Details—Opens the Chain dialog box to modify the properties of the selected chain.
* For more information on Chains search the Fundamentals functional area of the Creo Help Center.
Section plane control—Sets how the section plane is oriented (the z-direction of the sweeping coordinate system).
Normal To Trajectory—The section plane remains normal (perpendicular) to the specified trajectory (checked in the N column) throughout its length. This is the default.
Normal To Projection—The z-axis is tangent to the origin trajectory projection at the direction specified. The Direction reference collector activates prompting you to choose a direction reference. No horizontal/vertical control is required.
Constant Normal Direction—The z-axis is parallel to a specified direction vector. The Direction reference collector activates, prompting you to choose a direction reference.
Direction reference collector—Displays a plane, an axis, a coordinate system axis, or a straight entity to define the projection direction when Normal To Projection or Constant Normal Direction is selected. Flip reverses the reference direction.
Horizontal/Vertical control—Determines how the frame rotation around the sketch plane's normal is oriented along the swept blend.
Normal To Surface—The y-axis points in the direction of the surface selected, normal to any surface associated with the origin trajectory. This is the default when the origin trajectory has at least one associated surface. Click Next to toggle through possible surfaces.
X-Trajectory—Visible when there are two trajectories. The x-trajectory is the secondary trajectory and it must be longer than the origin trajectory.
Automatic—Determines x-axis position along the origin trajectory. This is the default when no surfaces are associated with the origin trajectory.
X direction reference at start collector—Displays the x-axis direction at the start of the trajectory. A direction reference can be a datum plane, datum axis, coordinate system axis, or any linear entity. When the collector is empty, the system automatically determines a Default x-axis direction at the start of the swept blend.
Flip—Click to flip reference direction.
Cross section types. Select one option. Section types cannot be mixed.
Sketched Sections—Select a point on the trajectory and click Sketch to define a cross section for the swept blend.
Selected Sections—Select previously defined sections as swept blend cross sections.
Sections table—Lists the cross sections defined for the swept blend. Each row of the table acts as a reference collector. Only one section is active at a time. Sections are numbered and ordered chronologically as they are added to the list. The column labeled #, displays the number of entities in the sketched cross section.
Insert—Activates a new collector. The new section is the active section.
Remove—Removes the selected section from the table and the swept blend.
Sketch—Opens Sketcher to define a sketch for the cross section.
Details—Opens the Chain dialog box to modify the properties of the selected chain.
Select Location collector—Displays a chain end, vertex, or datum point to locate a section.
Rotation—Specifies the section’s rotation angle about the z-axis (with a value from -120° to +120°) for each vertex or datum point where a section is defined.
Section X-axis directions—Set the x-axis direction for the active section. Available only when Automatic is selected for x-/y-axis control. When Horizontal/Vertical control on the References tab is selected, the section x-axis direction in the Sections tab is synchronized with the x-direction reference at start.
Add Blend Vertex—Places a handle on a vertex of the selected section. Drag the handle to the desired vertex.
You cannot add a Blend Vertex at the start point of a section.
You can add Blend Vertices only to start and end sections which are located at trajectory vertices. You cannot add to intermediate sections.
* A section containing a sketch point must be a start or end section and not an intermediate section.
Defines tangency between the geometry produced by start or end section entities and component surfaces.
* You cannot define tangency for a thin protrusion.
Tangency table
Boundary—Defines start or end section for setting tangency.
Free—The start or end section is a free end.
Tangent—Select a surface for tangency. The Entities collector advances automatically to the next entity.
Normal—The start or end of the swept blend will be normal to the section plane. The Entities collectors are not available and no references are required.
When a sketched end section contains a single point, these options are available:
Sharp—No tangency (the default).
Smooth—Tangency. The entity table is not available.
Sets options for controlling the shape of the Swept Blend between its sections.
Cap ends check box—Closes each end of a swept blend. Available for surface swept blends with a closed section and an open trajectory.
Adjust to keep tangency check box—Maintains the tangency of the surfaces that are created when the sections are blended.
Blend control options:
No blend control—Does not set blend control.
Set perimeter control—Makes the perimeter of the blend vary linearly between sections. Opens the Create curve through center of blend check box to place the curve at the center of the swept blend.
Set cross-section area control—Specifies a cross section area at specified locations of the swept blend.
Cross section table
Select points on the trajectory and enter the cross section areas. Predefined cross sections appear in non-editable rows.
Location—Displays cross section location.
Area—Displays cross section area.
* Area control conflicts are indicated by a yellow dot in the collector. Right-click and choose What's wrong to open the Troubleshooter dialog box. The message area of the dialog box informs you of the action to take. When the area control point is out of range as a result of geometry modifications performed outside of the tool, a warning message is displayed. Click Tools > Geometry Checks. The Troubleshooter dialog box opens.
Name box—Sets a name for a swept blend.
—Displays detailed component information in a browser.
