Sketcher constraint symbols Moving from Sketch to 3D When a Sketcher section gains depth, or a z-dimension, it becomes a 3D geometric entity called an extrusion. The extrusion may add or remove material. It can be a solid, or it can be a cut. For an example of a solid, imagine a 2D circle moving outward to create a cylinder. An extrusion created as a cut removes material from any solid it passes through. For example, a bolt hole through a plate can be a circular section placed on the surface of the plate as a cut and then extruded through the plate. An extrusion need not be defined as a cut or a solid when it is created. You can toggle the cut or solid property at any time. Extrusions can be defined in several ways. For example, both protrusions and cuts can be extruded, with depth added directly to a section, or revolved, where the depth of the cut or solid is added in degrees around an axis. 3-6 Getting Started with Pro/ENGINEER Wildfire 2.0
Left: Extruded protrusion. Right: Revolved protrusion When the section is complete and you have exited Sketcher mode, you are prompted to define the depth. It can be defined either numerically or in terms of another feature. In other words, the depth of an entity can be exactly 30 units, or it can be defined as “until the next feature begins”. Redefining Features As the model evolves, features will frequently be redefined. To do this, right-click the feature in the graphics window or in the Model Tree. From the shortcut menu, click Edit Definition. Features created as sections in Sketcher can also be selected and redefined in 3D mode. This direct modeling methodology is the recommended and more convenient way to edit models as they progress. Making a Block: The Sketcher Setup Sequence This exercise provides step-by-step instruction on how to create a simple solid in Sketcher. Make sure a new, empty part file is open in Pro/ENGINEER. Datums should be displayed. To create the sample block, an extrusion, a dimensioned 3D volume is created. An extrusion can add material, or it can remove material. 1. Click Insert > Extrude, or click the Extrude tool on the Feature toolbar. The Extrude dashboard opens. 2. In the dashboard, click Placement, then Define. The Sketch dialog box opens. The Plane collector box is highlighted in yellow. This means it is active, waiting for a sketching plane. 3. Click the Front datum plane in the graphics window. The datum plane name appears in the Plane collector and the highlight moves to the next collector, the Reference collector. A direction arrow appears from the sketching plane, pointing in the direction of the extrusion. The Flip button in the Sketch dialog box changes the direction of the Front datum plane if required. For this example, accept the default Part Design Basics 3-7
