CAD CAM CAE: NX 11 DESIGN FEATURE

Extrude

Use the Extrude command to create a solid or sheet body by selecting a section of curves, edges, faces, sketches, or curve features and extending them a linear distance.

The following example shows how Extrude can form a solid body from a section of curves.

You can:

· Size an extrude feature by dragging distance handles or specifying distance values.

· Unite, subtract or intersect an extrude feature with existing bodies.

· Produce multiple sheet or solid bodies with a single extrude feature.

· Trim an extrude feature using faces, datum planes or solid bodies.

· Add drafts to an extrude feature.

· Add offsets to an extrude feature, measured from its base section.

Use the Hole command to add the following types of hole features in a part or assembly:

· General holes (simple, counterbored, countersunk, or tapered form)

· Drill Size holes

· Screw Clearance holes (simple, counterbored, or countersunk form)

Pocket

Use the Pocket option to create a cavity in an existing body, using one of the following methods:

Cylindrical	Lets you define a circular pocket, to a specific depth, with or without a blended floor, having straight or tapered sides.
Rectangular	Lets you define a rectangular pocket, to a specific length, width, and depth, with specific radii in the corners and on the floor, having straight or tapered sides.
General	Lets you define a pocket with much greater flexibility than the cylindrical and rectangular pocket options.

Pad

Use the Pad option to create a pad on an existing solid body.

You can use either of the following methods to create a pad:

Rectangular	Lets you define a pad to a specific length, width, and depth, with specific radii in the corners, having straight or tapered sides.
General	Lets you define a pad with greater flexibility than the rectangular pad option.

Rib

Use the Rib command to add a thin-wall rib or rib network to a solid body by extruding an intersecting planar section.

Ribs are created based on a planar section of curves. The section can be any combination of curves:

You can specify a wall direction where the rib walls are perpendicular to the section plane or parallel to it.

Emboss

Modifies a body with faces made by projecting a section along a vector. Emboss features are useful for stiffener and locator objects.

There is a wide range of ways to control and manage the shape and orientation of the emboss, its end caps, and its sidewalls.

Emboss created on surfaces using a rectangular section

To create an emboss, you must specify:

· A closed section.

· The faces to emboss.

· An emboss direction (or accept the default, normal to section).

You can define the end cap (the floor or ceiling of the emboss) by choosing from a number of methods. For example, you could define the end cap as the offset of the selected faces to emboss.

You can specify that the sidewalls be drafted and where the draft starts (for example, draft from the end cap).

You can also create an emboss feature with edges trimmed by adjacent faces or, if the emboss falls on a free-edge boundary, by a user-selected vector.

Offset Emboss

Designed specifically for creating stiffening features in “body in white,” Offset Emboss produces relatively simple linear embosses on sheet surfaces. You can create these emboss features rapidly and predictably, but you don't have as many options as with the regular Emboss command.

Special connection rules ensure that all vertices of the pad are connected by sidewall faces to corresponding vertices on the trimmed input sheet.

Slot

This option lets you create a passage through or into a solid body in the shape of a straight slot. An automatic subtract is performed on the current target solid. The depth value for all slot types is measured normal to the planar placement face.

Groove

This option lets you create a groove in a solid body, as if a form tool moved inward (from an external placement face) or outward (from an internal placement face) on a rotating part, as with a turning operation.

You can create the following types of grooves:

Rectangular	A groove that leaves sharp corners all around.
Ball-End	A groove that leaves a full radius at the bottom.
U-Groove	A groove that leaves radii in the corners.

Common Concepts

Groove operates only on cylindrical or conical faces. The axis of rotation is the axis of the selected face. The groove is created near the location where the face is selected (the pick point) and is automatically linked to the selected face.

You can choose an external or internal face as the groove placement face, as shown in the figure below.

The profile of the groove is symmetric about a plane passing through the pick point and perpendicular to the axis of rotation, as shown in the figure below.

Positioning a groove works somewhat differently than other form features. You only have to position the groove in one direction, i.e., along the axis of the target solid. No positioning dimension menu appears. You position the groove by selecting a target solid edge and then the tool (that is, the groove) edge or centerline. See the figure below for an illustration.

Dart

This function lets you add a dart feature along the intersection curve of two sets of faces.

1. First Face Set 2. Intersection Curve 3. Second Face Set 4. Dart

To create a dart feature you must specify:

· Two sets of faces that intersect. A face set can be a single face or several faces.

· A base location point for the dart, either

o a point along the intersection curve, or

o a point at the intersection of the intersection curve and a plane.

· A depth.

· An angle.

· A radius.

By default the orientation of the dart is on a plane that is perpendicular to the intersection curve of the two sets of faces, but you can define the orientation yourself.

Thread

Use the Thread command to create either symbolic or detailed threads on cylindrical faces.

· Symbolic threads capture information from external thread tables and are recognized by downstream applications such as drafting. Symbolic threads are represented by dashed circles at the start and the end of the threaded length.

You can make a symbolic thread partly associative or specify a fixed length. Partly associative means that if the thread is modified, the feature will update, but not vice versa.

The behavior of the symbolic thread feature is slightly different from other features due to its display. The dashed circles associated with the thread behave like NX geometry. For example, they can be selected as arcs with the Information options, and they are added to layers as geometric objects.

· Detailed threads offer realistic renderings. They do not capture callout information and they are not recognized by downstream applications. While they do look more realistic, they produce complex geometry which takes longer to update.

Detailed threads are fully associative; if the feature is modified, its thread updates accordingly.

Note	Detailed threads must be created one at a time, while symbolic threads take less time to create and can be created in multiple sets. For these reasons, along with the advantages of using customized thread tables, we recommend that you create symbolic threads unless you need greater detail.
