Mechanical Engineering Dept., SJSU Creating Solids Sketched Features - (extrusions, revolves, sweeps, blends, ..) These features require a two-dimensional drawing (cross section) which is then manipulated into the third dimension. Although they usually use existing geometry for references, they do not specifically require this. These features will involve the use of an important tool called Sketcher. Revolve Sweep Blend Extrude Select a datum plane to draw. Create a 2D sketch. Create a feature from the sketch by extruding, revolving, sweeping, …. Ken Youssefi Mechanical Engineering Dept., SJSU

Mechanical Engineering Dept., SJSU Creating Solids Placed Features - (holes, rounds, shells, ...) These are features that are created directly on existing solid geometry. Examples are placing a hole on an existing surface, or creating a round on an existing edge of a part. Hole Shell Rib Draft Round Chamfer Ken Youssefi Mechanical Engineering Dept., SJSU

Implicit Constraints in Sketcher Ken Youssefi Mechanical Engineering Dept., SJSU

Example of Implicit Constraints vertical lines horizontal lines perpendicular lines tangency equal length lines equal radius vertical alignment Ken Youssefi Mechanical Engineering Dept., SJSU

Setting Sketch Orientation Sketch plane - the plane on which you will draw and your view is always perpendicular to the sketch plane. The Orientation option list in the dialog window (Top, Bottom, Left, Right) refers to directions relative to the computer screen, as in “TOP edge of the screen” or “BOTTOM edge of the screen” and so on. This orientation must be combined with a chosen reference plane (which must be perpendicular to the sketch plane) so that the desired direction of view onto the sketching plane is obtained.

Weak vs. Strong Dimensions A dimension created by Sketcher is called “weak” and is shown in gray. Strong dimensions, on the other hand, are those that you create. Sketch with weak dimensions You can make a strong dimension in any of three ways: Modify the value of a weak dimension Create a dimension from scratch by identifying entities in the sketch and placing a new dimension on the sketch Select a weak dimension and promote it to strong using the RMB pop-up menu Ken Youssefi Mechanical Engineering Dept., SJSU

Over and Under Constrained Sketch If there is not enough information to define the drawing (it is underconstrained), Sketcher will create the necessary and sufficient missing dimensions.These are the weak dimensions. If Sketcher finds the drawing is overconstrained (too many dimensions or constraints) it will first try to solve the sketch by deleting one or more of the weak dimensions (the ones it made itself earlier). However, if Sketcher still finds the drawing overconstrained, it will tell you what the redundant information is (which may be dimensions or constraints), Ken Youssefi Mechanical Engineering Dept., SJSU

Mechanical Engineering Dept., SJSU Creating a Swept Blend Feature The Normal to Trajectory option keeps each of the feature’s cross sections normal to the trajectory of the feature. Each section is created normal to a vertex of the trajectory or normal to a datum point on the trajectory. It requires the definition of a trajectory and the definition of one or more sections option keeps the feature’s cross sections normal to a second trajectory. Each section of the feature is created perpendicular to the normal trajectory. The option requires the definition of a sweep trajectory, a normal trajectory, and two or more sections. The Normal to Projection option keeps the feature’s cross sections normal to a selected planar pivot plane, edge, curve, or axis. Each section of the feature is created normal to the selected pivot plane. It requires the definition of a trajectory a normal plane and the definition of one or more sections.
