CEEGR 1050 – Graphics and Communication Fall 2017 CadLAB 7– DIMENSIONS AND VIEWPORTS

CadLab 8 covers two skills: creation of dimensions, and creation of layouts using viewports. Chapter 13 covers dimensioning, including standards of practice for showing dimension lines, and how to format DIMSTYLE and Line Settings. Chapter 14 covers creating layouts and viewports, including setting viewport scales and using PSLTSCALE. The assignment involves completing exercises from these chapters to develop skills necessary for project completion. Students are instructed to open specific drawings, complete given projects, modify layouts with viewports, set scales, create scale bars, prepare drawings for plotting, and email their final files with specific subject lines. Additionally, students will create an 11x17 layout called 'LEDGER,' insert title blocks scaled appropriately, set viewport scales, and make necessary plotting adjustments including color table modifications. The final deliverables include plotted hard copies and emailed CAD drawings.

Paper For Above instruction

In this CADLab exercise, students will develop proficiency in dimensioning and layout creation using viewports within AutoCAD, aligning with real-world drafting standards and presentation techniques. The activities aim to enhance technical communication skills by mastering precise dimensioning, proper layer management, viewport scalability, and plot preparation. These skills are essential for producing professional CAD drawings suitable for construction documents or presentation showcases.

The process begins with opening an existing drawing file, making necessary copies, and progressing through specific project tasks detailed in the instructions. Emphasis is placed on properly formatting dimension styles, setting viewport scales accurately, and ensuring the line types and hatch patterns display correctly and legibly both on-screen and in printed form. Critical to these exercises is the understanding of plotting parameters, including setting monochrome plot styles, adjusting layer line weights, and setting scale bars to represent real-world dimensions faithfully.

Creating an 'LEDGER' layout on an 11x17 sheet allows students to simulate presentation sheets or project portfolios. This requires setting up the page layout, scaling the title block correctly, inserting viewports with appropriate scales, and ensuring the entire building is visible and annotated with dimensions and labels. Adjustments to plot styles and previewing plots ensure the final output is accurate and professional in appearance.

These exercises reinforce fundamental CAD skills such as layer management, viewport creation, scale adjustment, annotation, and plotting. Mastery of these techniques enables students to produce clear, accurate, and well-organized drawings that can be used for client communication, construction planning, or academic evaluation. The emphasis on proper scale, line types, and plot settings reflects industry standards, fostering good drafting habits and technical competence among students.
