7Creating 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.
- Select a datum plane to draw.
- Create a 2D sketch.
- Create a feature from the sketch by extruding,
revolving, sweeping, .
8Creating 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.

10Implicit Constraints in Sketcher
11Example of Implicit Constraints
- vertical lines
- horizontal lines
- perpendicular lines
- tangency
- equal length lines
- equal radius
- vertical alignment
12Setting 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.

17Weak 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
18Over 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),

31Creating a Swept Blend Feature
32Creating a Swept Blend Feature
The Normal to Trajectory
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. It requires the definition of a
trajectory and the definition of one or more
sections
