Extrude and Revolve Features

Introduction

Solid features can be created using a variety of techniques. The most common solid features areExtrude and Revolve. These features are created by sketching the shape on an existing planarsurface. Extruded features are created ‘normal’ to the sketch plane. Revolved features arerevolved about a sketched centerline.When creating a new part, the ‘template’ includes three ‘Datum Planes’ that are used as afoundation for the model. The first solid feature is sketched and oriented using these datumplanes. Subsequent features can also be sketched on the datum planes or on solid surfaces of themodel.Examples of Extrude and Revolve features are shown below.

Dashboard Tools

The system uses ‘dashboard’ tools for defining the various elements of the feature. Extrudedfeatures are created using the Extrude Tool as shown below. These tools includes right mousebutton popup menus for shortcuts to common elements of the feature being created.

Internal Vs External Sections

Traditional Pro/ENGINEER features use an internal section; the section (or sketch) is part of thefeature.Pro/ENGINEER allows the use of existingdatum curves to define the shape of newfeatures. When this is done, the section isconsidered external. External sections arecopied from the selected datum curve, andbecome independent of the curve, meaning ifthe curve is modified, the copied section doesnot update.

To create an extruded feature with an internal section, pick the Sketch icon in the Extrude Toolas shown below. The Section dialog box is used to control the elements of the internal section.

Sketch Plane and Reference Plane

The Sketch plane is the plane you sketch on. The Reference plane is another plane used torotationally orient the Sketch plane. The system usually selects a reference plane for you, andyou can accept it or select a different one before sketching the section.The Section dialog box controls the Sketch plane, the viewing direction, the Reference plane,and the orientation of the Reference plane relative to the monitor. The Section dialog box isshown below.

Protrusion Vs Cut

A Protrusion adds material to the model. A Cut removes material from the model. Bothextruded protrusions and extruded cuts can be created using the Extrude Tool as shown below.The system defaults to Protrusion, pick as shown below to create a Cut.

Extrude Direction

The Direction of the extruded feature can be flipped on the model or in the Extrude Tool asshown below.

When you want to extrude in both directions from the sketching plane, use the Options panel ofthe Extrude Tool as shown below.

Material Side

Extruded features that remove material from the model are called Cuts. The Material Side arrowcontrols on which side of the sketch the system removes the material.The Material Side arrow points toward the material to be removed as shown below.

Pick here to remove(cut) material

Extruded Depth Options

When creating extruded features, many options are available to define the depth of the feature.Each of the depth options are described below, and the icons are shown at the bottom of the page.

Blind Depth is controlled by a dimension on one side of the sketch plane.

Symmetrical Blind Depth is controlled by a single dimension symmetrical on both sides of thesketch plane.

Thru Next Depth is controlled by the next part surface the feature completelyintersects. In other words, the surface must be bigger than the feature beingcreated.

Thru All Go all the way through the part.

Thru Until Depth is controlled by selecting a part surface the feature completelyintersects. In other words, the surface must be bigger than the feature beingcreated.

Up To Entity Depth is controlled by a datum point, or a vertex, or a datum curve, or apart surface, or a datum plane. The feature does not have to completelyintersect the surface.

Creating Extruded Features

The process of creating extruded features is complex. Use this page as a guide to creatingextruded features.Start by picking the Extrude Tool icon (1) thenpick the Internal Sketch button (2) in the ExtrudeTool. After selecting the sketch plane pick theSketch button (3) in the Section dialog box. Aftercompleting the sketch, pick the Done icon (4).

In the Extrude Tool, set the Class (5) to Solid or Surface,set the Depth (6), Set the Type (7) to Protrusion or Cut.

In the graphics window, pick the arrows if necessary to flipthe direction arrow (8) and material side arrow (9).Drag the depth handle (10) to the desired depthor double pick the dimension to enter a value.Pick the checkmark (11) or click the middlemouse button to complete the feature.Use one of the config.pro options shown below tocontrol the grid snap of the drag handles.
