A chemical is applied to the inside of the socket, and the pipe is then forced into the socket. The solvent softens the plastic, and when the solvent dries, a strong, permanent joint is created. The sockets are tapered slightly to allow for a tight fit with the pipe.
Module 4: Additional Part Modeling
This module provides a comprehensive understanding on additional modeling techniques such as:
Revolved, Patterning, Swept, Lofted, Rib and Shell features in SolidWorks.
Below are examples of products that applied these types of features.
Revolved features
Revolved Boss/Base – material added by rotating the profiles about a centerline Revolved Cut – material removed by rotating the sketch
The Revolve parameters box provides the ability to select:
Centerline
One of the lines is collinear with the centerline to make a solid cylinder
Allow a small gap between rectangle and the centerline to create a hollow cylinder
Axis of Revolution Revolve Type
• One-Direction
• Mid-Plane
• Two-Direction
Angle
It controls the revolve thickness
Tutorial 4.1:

13. Select Circular Pattern from Features toolbar. Number of holes are 6.
14. The completed part.
Patterning
In Module 2, you have learnt the sketch pattern such as linear and circular pattern. There are other pattern tools that are available in SolidWorks. You may find them at Insert – Pattern/Mirror.
Pattern repeats the selected features in an array based on a seed feature. You can create a linear pattern, a circular pattern, a curve driven pattern, a fill pattern, or use sketch points or table coordinates to create the pattern.
Linear pattern Select the features, then specify the direction, the linear spacing, and the total number of instances.
Circular pattern Select the features and an edge or axis as the center of rotation, and then specify the total number of instances and the angular spacing between instances.
Curve driven
pattern Select the features and an edge or sketch segment on which to pattern the feature.
Then you can specify the type of curve, the curve method, and the alignment method.
Fill pattern Fill a defined region with a pattern of features or a predefined cut shape.
Typical uses include:
• Weight reduction
• Ventilation holes Sketch points
or Table
coordinates to create the pattern
Select where to populate a seed feature by sketching points on model face, or Add or retrieve previously created X-Y coordinates to populate a seed feature on the face of the model.

Follow path – the section remains at the same angle with
respect to the path at all times.
Keep Normal Constant – the section remains parallel to the beginning section at all times.

Loft creates a feature by making transitions between profiles. A loft can be a base, boss, cut, or surface. You create a loft using two or more profiles. Only the first, last, or first and last profiles can be points. All sketch entities, including guide curves and profiles, can be contained in a single 3D sketch.
You can drag to modify/change the location of these blue points
(closing point)

Module 5: Assembly Modeling
Stages in the process;
1. Creating a new assembly
• New assemblies are created using the same method as new parts
2. Adding the first component
• Components can be added in several ways. They can be dragged and dropped from an open part window or opened from standard browser.
3. Position of the first component
• The initial component added to the assembly is automatically fixed as it is added.
Others components can be positioned after they are added.
4. Mating components to each other
• Mates are used to position and orient components with reference to each other. Mates remove degrees of freedom from the components.
Concentric mate between two cylindrical faces
5. Sub assemblies
• Assemblies can be created and inserted into the current assembly. They are considered sub-assembly components.
From assemblies, you can:
1. Perform mass properties calculations on entire assemblies and also interference (clashes) detection between parts in assembly,
2. Create an exploded view of an assembly,
Assembly toolbars
Basic assembly mates
• Coincident – place two flat surfaces in the same plane
• Parallel – define two flat surfaces as parallel
• Perpendicular – define two lines or planes as perpendicular to one another
• Tangent – define a cylindrical feature as tangent to a line or plane
• Concentric – align the centerlines of two cylindrical features
• Distance – make two surfaces parallel, with a specified distance between them
• Angle – two lines or planes at a preset angle to one another
• Insert components
• Hide/show components
• Change suppression state
• Edit component
• Interference detection
• Simulation
