Engineering Graphics & CAD

What you'll learn

• Explain the purpose and types of engineering drawings, read title blocks, sheet sizes, scales and line types, and identify the ASME and ISO standards that govern a drawing.
• Produce clear, proportional freehand sketches in orthographic and isometric form, and use sketching to visualize, record and communicate shapes.
• Create and read orthographic views in third-angle and first-angle projection, choose appropriate views, and classify normal, inclined and oblique surfaces.
• Construct isometric, oblique and perspective pictorials, apply axis scales and ellipse rules, and choose the pictorial best suited to a purpose.
• Draw and interpret full, half, offset, broken-out, revolved, removed and aligned sections, applying section-lining conventions for ribs and standard parts.
• Construct primary and secondary auxiliary views to show inclined and oblique surfaces in true shape, and find true lengths and dihedral angles.
• Dimension parts completely and functionally using standard symbols, choose chain, baseline or direct dimensioning, and avoid over- and underdimensioning.
• Specify tolerances and select ISO and ANSI fits, calculate limits and clearances, choose bearing fits, and perform worst-case and RSS tolerance stack-ups.
• Read and write feature control frames, establish datum reference frames, and apply form and orientation tolerances under ASME Y14.5-2018 and ISO principles.
• Apply position tolerances with material condition modifiers, compute bonus tolerance and virtual condition, use fastener formulas, and specify profile and runout.
• Represent and specify metric, unified and pipe threads, fasteners and other standard parts, including tapped hole callouts and property classes.
• Build parametric models that capture design intent, create assemblies and bills of materials, and manage drawing release, revisions and model-based definition.
