Compound Profiles

(Available in Platinum)

A compound profile is an open or closed chain of connected curves or lines, or any set of closed curves or closed polylines. You can use compound profiles when you do not want to create a polyline or convert a chain into a polyline. Compound profiles can be used as paths for sweeps etc. and as profiles that are swept along paths. You can use blocks as compound profiles, however, there are restrictions. You can only only use one element in a block as a path for any given operation. Also, only closed sequences of curves, lines etc. (chains) or closed objects can be used to sweep, revolve etc. All such closed objects in the block selected to sweep, revolve, etc will used in the resulting 3D object.

Extrude to Face

1. Select the 3D object to be the target of the extrusion.

1. The result is a new 3D object.

If the boolean option is set to Subtract, the extrusion will be subtracted from the target body, and the original 3D object from which the extrusion was made will be removed.

You can extrude multiple faces at one time, but you can extrude to only a single 3D object.

1. Hold down the SHIFT key to select multiple faces.

1. Release the SHIFT key and select the target object.

1. You will have a multiple extension.

There are some limitations that must be respected to create valid result. Resulting extrusions must intersect the target body when extended, or the operation will be invalid. You cannot extrude adjacent faces. Adjacent faces are extended along with the extrusion face. Adjacent curved faces and adjacent slanted faces will continue their curve or slant when the selected face it extruded .

You can extend to ACIS surfaces, but only if the target body completely intersects the resulting extrusion.

You cannot extrude a face to the same 3D object that the extrusion face belongs to.

When extruding to a ACIS surface you can remove the remnant "excess" of the target surface using the Facet Edit tool.

1. Select the facet.

The closed area must be co-planar with the Flat face of a 3D object. It may consist of:

• Any closed 2D entity. E.g. a rectangle.
• Any area that can be hatched by picking a point (with zero gap tolerance).
• Areas enclosed by crossing co-planar, linear geometry, including edges and geometry in blocks E.g. intersecting lines that create a closure.
• 3D faces. E.g. The face of a cube
• Any combination of the above.

Areas created by geometry (including edges on faces) drawn co-planar to any face of a 3D solid E.g. A circle is co-planar with the face of a cube. It overlaps the edge of the cube. The edge divides the circle into two parts, one is a valid area, or intersecting lines that create a closure on the face of a 3D object, with or without defining geometry of the 3D entity

Quick Pull Properties

The Properties window of an Quick Pull object contains a Simple Extrude Shape page, in which you can set parameters defining how the object is created. Height: The distance of the extrusion. Direction: Switch between one-sided and two-sided. Solid Options: For these parameters to be accessible, the extrusion must be created as a solid. Draft Angle: Creates an extrusion of increasing or decreasing cross-section. Enter the angle of deviation from the extrusion path. Draft Start / End Distance: If Draft Angle = 0, you can specify a draft angle by entering the draft distances. Offset: Creates a hole in the extrusion at a distance from the outside of the extrusion equal to the Offset value. The Quick Pull and the Simple Extrude tool use the same Property Value Preset. Therefore, changing the property settings in one tool will change the settings in the other.

Quick Pull and 2D Surfaces

You can use The Quick Pull tool to thicken a flat 2D surface. (This must be an ACIS solid / TC surface)

For example,

1. Take a 2D Polyline

1. Extrude it with the Simple Extrude tool

1. Fillet the corner.

1. Then use the Push mode of the Quick Pull tool to give it some thickness.

View the following video for more info on using the the Quick Pull tool on TC Surface.

Pulling Curved Faces

Curved faces can also be pulled with the Quick Pull tool. However there are some limitations.

1. Only faces which have circular curves can be pulled. E.g. Cylinders, Fillets, and Bends.
2. Elliptical, spline, Bezier or spherical surfaces cannot be pulled.
3. A curved surface will normally disassociate tangency from adjacent planar surfaces when it is pulled.
4. Interlocked adjacent curved cases can prevent this from functioning.

To use the Quick Pull on a curve: Select the tool. Hover over the desired surface until it highlights. Click on the surface. Move the cursor left of right to push or pull the face in or out. Alternately you can TAB into the Inspector bar, enter a new radius and press ENTER. Click to set the new radius.

Click on the surface. Move the cursor left of right to push or pull the face in or out. Alternately you can TAB into the Inspector bar, enter a new radius and press ENTER. Click to set the new radius. There are some limitations While it is possible to select the face below it cannot be pulled because it is locked by the adjacent fillet.

Fillet – Detect Blend network

An additional option for pulling fillets is Detect Blend Network. When this option is On all adjacent fillets will be pulled simultaneously. Click on the surface. Move the cursor left of right to push or pull the face in or out. Alternately you can TAB into the Inspector bar, enter a new radius and press ENTER. Click to set the new radius.

Bends

Below are some use cases for pulling bends.

Rail Sweep

(Available in Platinum, Professional and Deluxe)

Default UI Menu: Draw/3D Object/3D Profile Based/Rail Sweep

Ribbon UI Menu:

Creates a 3D object by driving a 2D profile along a path. The profile and path do not have to touch or be in different workplanes; the profile section will be "brought" to the start of the path, made normal to the path, and swept along it.

Base Point

If you are going to use Compound profiles for both the path and the profile you will need a base point. The base point specifies the point though which the profile will follow the path. To create a base point, use the Point tool and place a point at the location adjacent to the profile that you wish to be used. For example, at the end of a line, or at the center of an arc or circle.

Creating a Rail Sweep

1. Start with one 2D profile. The profile can be open or closed. Add a 2D or 3D path. The path can lie anywhere, and in any workplane. In this example, profile and path lie in the same workplane.

1. Activate Rail Sweep.
2. If the profiles consist of compound curves, make sure Use Compound Profile is active.

1. Select the first 2D profile. If the profile is open, select Finish Selection of Path to end the selection. You can then select more profiles if necessary, by pressing the Shift key.

1. If you are using a Compound profile for the profile you must specify the base point to be used. At this step select the point you created for this purpose.
2. Then select the sweep path. If the sweep path consists of more than one curve, make sure Use Compound Profile is active.

1. The profile is brought to the path (at the base point if one is being used) and swept along it, normal to the path. The profile intersects the path at its reference point.

This tool is handy if you have a single profile that you want to sweep over multiple paths, or rails. In this example, there are three paths for the same profile:

Here are the results:

If you used a Compound profile for the profile, you will be able to modify the resulting 3D object by modifying the original profile object or by moving the base point object. If you used a Compound profile for the path, you will be able to modify the resulting 3D object by modifying the original path object/s. The sweep path does not have to be 2D the path in this example was created using 3D Spline by Fit Points.

This is the result:

Local menu option Rigid Sweep: Keeps cross-sections of the solid parallel to one another along the entire path.

As stated before, the 2D profile and the sweep path do not have to intersect. However, the results will vary depending on how far apart the profiles are. Consider this comparison, in which the profiles on the left intersect and the profiles on the right do not.

Here are the Sweep results: the solid on the right is swept over the offset of the sweep path, and is therefore larger.

Local menu options Rigid Sweep: Use this option if you want the cross-sections of the solid to remain parallel to the original swept profile. This solid does not use Rigid Sweep; the cross-sections of the solid are always normal to the sweep path.

This is the same solid using Rigid Sweep; the sections are always parallel to one another, and to the original profile.

If you view the Rigid Sweep from this angle, you can see how the sections are parallel.

Use Edge as Path: When this option is ON you can use the edge of a 3D object as a path. You cannot use this option with a compound profile.

Use Loop as Path: When this option is on you can use the Loop of a 3D object as a path. A loop is all of the edges which enclose a single face of a 3D object You have to select the 3D object first, then its face. You cannot use this option with a compound profile.

Note: If you are trying to sweep by using a block as the path, you must have the Compound Path option turned on.

Sweep Shape Properties

The Properties window of an sweep object contains a Sweep Shape page, in which you can set geometric parameters.

For these parameters to be accessible, the sweep must be created as a solid.
