AutoCAD ACU case studies
AutoCAD ACU · Put your knowledge to work in context.
The Autodesk Certified User (ACU) for AutoCAD is the entry level of Autodesk's four-tier certification framework, sitting below Certified Associate, Certified Professional and Certified Expert. Autodesk describes the Certified User tier as being "developed for secondary students and non-English speakers in all industries," and says it "validates and highlights foundational Autodesk software skills and knowledge" - so it is positioned as proof of first-stage, working familiarity with the software rather than specialist-level problem solving. The AutoCAD ACU case studies are 5 cases and about 3,381 words.
1The 304.8 gap: a unitless survey xref
You have joined a firm whose project template is set to millimeters (INSUNITS = 4). A civil consultant delivers SITE-BASE.dwg, drawn correctly in US survey feet but saved with INSUNITS = 0 (unitless).

A 2,400-object mechanical plan arrives from a consultant as a DWG produced by exploding a PDF conversion. Every partition edge is drawn twice - sometimes offset by 0.02 mm - and the duplicates are scattered across five different layers.

Your 60-layer base plan is clean, but two drafters have been making objects print lighter by changing each object's colour in the Properties palette rather than by layer. The base is xref'd into 14 sheet files, and the project has just migrated from a colour-dependent (CTB) table to a named plot style table (STB) with five fixed styles.

A detail sheet shows the same wall section three times: an enlarged 1:20 viewport and two plan viewports at 1:100 and 1:50. All model-space annotation is annotative with a 2.5 mm plotted height.

A 1:200 site plan sits in a viewport on an A1 layout. The AR-SAND paving hatch looks correct when zoomed in close in model space, but plots as a solid black band in the PDF.
