Inventor ACU study plan

Inventor ACU · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

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

Week 2

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

Week 3

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

Week 4

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

Week 5

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

Week 6

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

Week 7

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

Week 8

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
