Mar 4 – Mar 29
Unit Summary
Students will develop and apply mathematical relationships to enforce appropriate dimensional and motion constraints. Students will also model a consumer product, providing appropriate parametric constraints to create a 3D model and realistic operation of the product
Big Ideas
Parametric computer aided design (CAD) software packages facilitate 3D virtual modeling of parts and assemblies using parameters, such as geometric constraints (the relationships between geometric entities) as well as numeric constraints (dimensions) used to determine the shape and size of geometry and models.
Technical drawings convey information according to an established set of drawing practices which allow for detailed and universal interpretation of the drawing.
The style of the engineering graphics and the type of drawings views used to detail an object vary depending upon the intended use of the graphic.
Essential Questions
Is it ever advantageous to create a design or solve a problem individually as opposed to using a team approach?
What quality makes a set of drawings sufficient to adequately represent the design intent?
Is it always necessary to indicate a tolerance for every dimension on a technical drawing?
Priority TEKS
Identify, define, and explain the proper use of an auxiliary view in technical drawing
Use advanced modeling features to create three dimensional solid models of complex parts and assemblies within CAD and with little guidance given the actual part using appropriate geometric and dimensional constraints.
Create an exploded assembly view of a multi-part product.
Identify each component of the assembly with identification numbers and create a parts list to detail each component using CAD
