    Creating Solids

    Sketched Features - (extrusions, revolves, sweeps, blends,

    ..) These features require a two-dimensional drawing (crosssection) which is then manipulated into the third dimension.

    Although they usually use existing geometry for references,

    they do not specifically require this. These features w i l l

    invo lve the use of an impo rtant tool cal led Sketcher.

    Creating Solids

    Placed Features - (holes, rounds, shells, ...) These arefeatures 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.

    Setting Sketch Or ientation

    Sketch plane- the plane on which you will draw and your view is alwaysperpendicular to the sketch plane.

    The Orientationoption 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

    Sketch with weak dimensions

    A dimension created by Sketcheris called weak and is shown in

    gray. Strong dimensions, on the

    other hand, are those that you

    create.

    You can make a strong dimension in any of three ways:

    1. Modify the value of a weak dimension2. Create a dimension from scratch by identifying entities in the sketch

    and placing a new dimension on the sketch

    3. Select a weak dimension and promote it to strong using the RMB

    pop-up menu

    Over and Under Constrained Sketch

    If there is not enough information to define the drawing (it

    is underconstrained), Sketcher will create the necessaryand 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 solvethe 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 redundantinformation is (which may be dimensions or constraints),

    Creating a Swept Blend Feature

    option keeps each of the

    features 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. Itrequires the definition of a trajectory and the definition of

    one or more sections

    option keeps the features

    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.

    Constant Normal Direction

    option keeps the features cross

    sections normal to a second trajectory. Each section of thefeature is created perpendicular to the normal trajectory. The

    option requires the definition of a sweep trajectory, a normal

    trajectory, and two or more sections.
