ADS study guide
ADS · Work through your exam, one topic at a time.
The Autodesk Certified Professional (ACP) AutoCAD for Design and Drafting credential is a vendor certification that validates professional-level proficiency with AutoCAD. Unlike an entry-level certificate, it assumes you already draft for a living or are preparing to: architectural, mechanical, civil, or interior-design technicians, drafters, and designers who need to prove they can produce accurate, standards-compliant construction documentation under time pressure rather than just navigate the interface. The ADS study guide has 8 sections and about 2,593 words.
01Drawings, Templates, and Layers
A drawing template (.dwt) is the fastest way to guarantee that every drawing in a project starts with the same layers, text and dimension styles, layouts, title block, units (INSUNITS, LUNITS, LUPREC) and named page setups. QNEW opens the file named in Options Files Template Settings Default Template File Name for QNEW, so a firm can point every new drawing at its own template instead of acad.dwt.
346 words, about 2 min02Drawing Objects and Annotation
LINE creates independent segments; PLINE creates one object that can mix straight and arc segments and carry width, which matters when a schedule counts objects or when the result must be offset. JOIN rebuilds polylines from touching lines and arcs.
307 words, about 2 min03Blocks, Attributes, and External References
A block definition lives inside the drawing and is placed by INSERT with an insertion point, scale and rotation. Redefining a block with BEDIT updates every insert, which is the main reason to use blocks for repeated content.
345 words, about 2 min04Layouts, Viewports, and Plotting
Model space holds full-size geometry; a layout is paper space measured in millimetres or inches at 1:1. MVIEW creates a viewport, and its scale is set from the standard scale list or the Viewport Scale control; lock the viewport once the scale is correct so accidental zooming cannot change it.
321 words, about 2 min05Dimensions, Tolerances, and Annotation Scaling
DIMSTYLE controls the geometry and text of dimensions through a parent style plus child styles for linear, angular, radius and diameter. Key variables include DIMSCALE (overall size factor), DIMLFAC (measurement multiplier), DIMTXT (text height) and DIMASSOC (2 = associative, so dimensions update with geometry; use DIMREGEN if they do not).
301 words, about 2 min06Object Selection, Modification, and Properties
Window selection (left-to-right) takes only objects entirely inside the box; crossing selection (right-to-left) takes anything touched. Lasso behaves the same way by direction.
333 words, about 2 min07Collaboration, Standards, and Drawing Management
A CAD standards file (.dws) stores approved layers, dimension styles, text styles, linetypes and lineweights. CHECKSTANDARDS compares the current drawing and offers Fix or Ignore for each violation, and the Standards tab at DWS creation decides which categories are audited.
302 words, about 2 min08Customization, Productivity, and Best Practices
The CUI editor controls menus, ribbon panels, toolbars, keyboard shortcuts, mouse buttons and double-click actions. A partial CUIx can be loaded alongside the main file, and an enterprise CUIx lets a CAD manager lock company menus while users keep their own workspace.
