Drafting Detailer 1

Course Description

TDR0775 – Drafting Detailer 1 is a 150-contact-hour Career and Technical Education (CTE) course within the Engineering Technologies > Technical Drafting taxonomy. It is designated as Occupational Completion Point C in Florida's Technical Drafting program sequence. Building on foundational drafting and CAD skills, this course advances students into intermediate-level detail drawing, multiview projection, sectional views, auxiliary views, and precision dimensioning using both manual drafting techniques and computer-aided design (CAD) software. Students develop the skills needed to produce accurate, industry-standard detail drawings suitable for employment as a drafting detailer in architectural, mechanical, civil, or structural environments.

This course is approved for Practical Arts graduation credit and is aligned to Florida Department of Education curriculum frameworks under the Architecture and Construction career cluster. Upon completion, students are prepared to seek entry-level employment as a Drafting Detailer or to continue into advanced drafting courses.

Learning Outcomes

Required Outcomes

Upon successful completion of this course, students will be able to:

• Apply intermediate drafting skills using manual instruments, measuring scales, and CAD software to produce accurate technical drawings.
• Produce multiview orthographic drawings using standard first- and third-angle projection techniques in compliance with ASME/ANSI drawing standards.
• Construct sectional views, including full, half, offset, broken-out, revolved, and removed sections, with correct hatching conventions.
• Create auxiliary views to describe inclined and oblique surfaces accurately.
• Apply precision dimensioning principles, including Geometric Dimensioning and Tolerancing (GD&T) for fits, finishes, and manufacturing specifications.
• Prepare detail and assembly drawings at intermediate complexity, including parts lists and bill of materials (BOM).
• Use CAD software (e.g., AutoCAD) to create, edit, annotate, and plot technical drawings to professional standards.
• Interpret and apply industry drawing standards and conventions (ASME Y14.5) in the production of working drawings.
• Demonstrate workplace readiness skills, including professional communication, project organization, and adherence to deadlines.

Optional / Enrichment Outcomes

The following outcomes may be covered based on instructor focus and program emphasis:

• Prepare basic 3D CAD models and extract 2D detail drawings from solid models.
• Produce structural detail drawings, including steel, reinforced concrete, or wood framing details.
• Create architectural detail drawings such as wall sections, door/window schedules, and finish details.
• Prepare mechanical detail drawings, including thread representations, fasteners, and springs.
• Demonstrate introductory use of Building Information Modeling (BIM) concepts and software tools (e.g., Autodesk Revit).
• Apply descriptive geometry methods to solve problems involving points, lines, and planes in space.
