Inventor ACU study plan
Inventor ACU · Give each week a clear focus.
8 weeks · About 6 hours per week
Inventor fundamentals and the user interface
Map every major area of the Inventor interface by opening a new part, sketch, and assembly and labeling the ribbon tabs, browser tree, view cube, and navigation bar in your own notes
Create and save a custom keyboard shortcut set and a custom ribbon panel, then demonstrate both by running three commands without touching the mouse
Explain in writing the difference between a project file and a file, and set up one project with a workspace and library path you can reuse all course long
Practice file management by creating, renaming, copying, and packing a small set of parts into a folder and verifying the references survive
Your checkpoint
A one-page annotated interface map plus a saved custom shortcut/ribbon configuration file
Inventor fundamentals and the user interface & Sketching
Configure application options for sketch and display behavior, then justify each change you keep in a short written log
Set up a drawing template and a part template with your units, dimension style, and title block defaults, and confirm they load on a new file
Draw and fully constrain five basic sketch profiles using lines, arcs, and circles, applying geometric constraints before dimensions
Use the sketch doctor or constraint status tools to diagnose and fix one intentionally over-constrained sketch
Your checkpoint
A reusable template set (part and drawing) plus five fully constrained sketch files with zero remaining degrees of freedom
Sketching
Construct sketches using construction geometry, symmetry constraints, and equal constraints to reduce the number of dimensions needed
Apply patterns, mirrors, and offsets inside a sketch and predict how each affects the constraint count
Dimension sketches using driven versus driving dimensions and convert one of each to confirm the behavior
Insert an image-free reference geometry workflow by projecting edges from existing geometry and explain when projection is preferable to redrawing
Your checkpoint
A sketch portfolio of eight profiles, each fully constrained and each using at least one construction or pattern technique, saved with a written constraint count for each
Sketching & Part modeling
Convert three of your sketch profiles into base features using extrude with join, cut, and intersect operations
Build a revolved feature and a swept feature from sketches you author yourself, verifying the profile and path relationships
Create work planes, work axes, and work points on demand and use them to host a sketch that cannot be placed on existing faces
Diagnose and repair one failed feature by editing its sketch and its extents rather than deleting it
Your checkpoint
Three finished part files, each with at least four features, plus a short failure-and-fix writeup for one of them
Part modeling
Model a part using holes, fillets, chamfers, and shells, ordering the features so later edits do not break earlier ones
Use rectangular and circular feature patterns and mirror features, then edit one pattern instance count and confirm downstream features update
Apply parameters and user parameters to drive at least two dimensions, and change a parameter value to verify the model rebuilds correctly
Compare a multibody part approach with a separate-parts approach for one design and document the tradeoff
Your checkpoint
One parametric part driven by at least three named user parameters, with a screenshot-free written parameter table showing names, values, and what each controls
Part modeling & Assembly modeling and drawings
Create a drawing from one of your parts with base, projected, section, and detail views, and dimension each view
Place a parts list and balloons on an assembly drawing and edit the style so it matches your template
Build an assembly from your existing parts using mate, flush, and angle constraints, and check for remaining degrees of freedom
Insert a subassembly and demonstrate that constraints at the top level do not over-constrain the child components
Your checkpoint
A two-sheet drawing set (part drawing and assembly drawing) with a parts list, balloons, and section view
Assembly modeling and drawings
Create an assembly pattern of components and a mirrored component, then verify the bill of materials reflects the correct quantities
Use interference checking and contact analysis on your assembly and resolve at least one interference
Drive a constraint or parameter to produce two assembly configurations and capture both in the drawing or a written comparison
Annotate a drawing with a revision table and a custom title block field that pulls from model properties
Your checkpoint
A revised assembly model and drawing with resolved interference, a working revision table, and two documented configurations
Inventor fundamentals and the user interface & Sketching & Part modeling & Assembly modeling and drawings
Rebuild a small three-part assembly from scratch under a time limit to rehearse the full workflow from project setup to drawing
Review your weakest domain by reworking two failed or incomplete exercises from earlier weeks without notes
Compile a one-page reference card of the commands, shortcuts, and constraint rules you used most
Take a full-length timed practice set and log every missed item by domain
Your checkpoint
A timed end-to-end project (part, assembly, drawing) completed within the time limit plus a domain-tagged error log
Milestones
Week 2: Can create a new part from your own template, set up a project, and produce a fully constrained sketch without consulting notes
Week 4: Can model a four-feature part from a hand sketch and repair one failed feature without deleting it
Week 6: Can produce a dimensioned drawing with a section view and a parts list from an assembly you built
Week 8: Complete a timed part-assembly-drawing project end to end and score at least 80 percent on a full-length practice set
