Solid Work Modeling
1.0 Objective
Understanding of Solid works modeling Steps and to practice line, circle and rectangle sketch
entities with a 2D practice drawing.
Theory
2.0 Solid Modelling
A solid model is the most complete type of geometric model used in CAD systems. It contains
all the wire frame and surface geometry necessary to fully describe the edges and faces of the
model. In addition to the geometric information, it has the information called topology that
relates the geometry together. An example of topology would be which faces (surfaces) meet
at which edge (curve). This intelligence makes operations such a filleting as easy as selecting
an edge and specifying a radius.
3.0 Basic steps of modeling
1. Select a face or plane
2. Start a new sketch
3. Draw geometry
4. Tie the geometry to the origin
5. Add relations
6. Create the feature (extrude, revolve & extruded cut etc.)
4.0 Sketch entities
Line command
1. Click on line command.
2. In the insert line property manager under orientation, select one of the following:
As sketched
Horizontal
Vertical
Angle

Circle command
1. Click circle command.
2. Click to the place to the center of the circle.
3. Drag & click to set the radius & click.
Rectangular command
You can sketch the following rectangle types:
Rectangle type Tool Rectangle properties
Corner Rectangle Sketches standard rectangles.
Center Rectangle Sketches rectangles at a center point.
3 Point Corner Rectangle Sketches rectangles at a selected angle.
3 Point Center Rectangle Sketches rectangles with a center point at a selected angle.
Parallelogram Sketches a standard parallelogram.
The SolidWorks application defaults to the last used rectangle type. You can also use the
rectangle tools (Sketch toolbar).
To access the rectangle tools:
Sketch tab. Click the Rectangle Command Manager, to select rectangle tools from
the Rectangle flyout tool.
Menu. Click Tools > Sketch Entities to select rectangle tools.
Rectangle Property Manager. Change to different rectangle tools from
the Rectangle Property Manager.

4.0 Dimensioning
Sketches are displayed in various states. To fully define the sketch, you add relations and apply
dimensions using the Smart Dimension tool (Dimensions/Relations toolbar). The types of
sketch entities can also affect dimensioning functions.
The Dimensions/Relations toolbar and the Tools, Dimensions and Tools, Relations
menus provide tools to dimension and to add and delete geometric relations. Status of a sketch
are given below;
Under Defined
There is inadequate definition of the sketch, but the sketch can still be used to create features.
This is good because many times in the early stages of the design process, there isn’t sufficient
information to fully define the sketch. When more information becomes available, the
remaining definition can be added at a later time. Under defined sketch geometry is blue (by
default).
Fully Defined
The sketch has complete information. Fully defined geometry is Black (by default). As a
general rule, when a model is completed, the sketches within it should be fully defined.
Over Defined
The sketch has duplicate dimensions or conflicting relations and it should not be used until
repaired. Unnecessary dimensions and relations should be deleted. Over defined geometry is
red (by default).

4. Smart dimension ( Fully defined)
Step 01
a) First I take the front view.
b) I take line command from menu bar.
c) In F.V, I draw the sketch at specified distance according to drawing dimensions.
