# Lesson Plan Pipe Parametric Modeling Skill Builder Advanced Engineering Design and Presentation

```Pipe Parametric Modeling Skill Builder
Lesson Plan
Performance Objective
At the end of the lesson, students will able to create the Pipe Drawing Problem as per the Pipe Drawing
Example given (to match the criteria in the Pipe Parametric Modeling Builder Rubric). Students will be
prepared to begin the Crazy for Reading Straw lesson.
Specific Objective
 Create the pipe drawing problem to specifications given
Terms
 Bend- the tangency line at which the existing part transitions into the bend feature's deformation area;
the line about which the feature hinges or folds.

Planes- X, Y, and Z that you can select to create a sketch on.
1

Sketch- the surface or plane area that you can draw your part on.

3D Sweep - Construction of 2D and 3D sweep solids is similar; both require a profile sketch to depict
the cross section of the sweep solid and a path sketch to specify the path of the sweep operation. The
difference between them lies in the shape of the sweep path. In a 2D sweep solid feature, the path
sketch is planar. In a 3D sweep solid feature, the path is three dimensional.

3D Sketch- provides a way to create a path for 3D sweep features. 3D sweep features define routed
parts such as wiring, cabling, and tubing in the context of an assembly or within a single part. Multiple
routed paths can represent sets of tubing or a wire harness.


Fillet- a rounded edge.
Time
It should take approximately 15 minutes to teach the lesson and 45 minutes for each of the two lab sessions.
