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.
