Industrial design review · Production guide
Annotate an exploded product view from an existing CAD model
The source model names B01 base, H01 hinge, A01 arm and L01 head. Separate these four named objects vertically for the explanation; retain a solid assembled view beside it.
Input and decision
Open the assembled model and make a list of the four object names before laying out the exploded view. Assign one number to each real source object. Pivot 01 is an original presentation model. Material and mechanical approval require their own evidence.
Set up the comparison
Compare the apparent order of the separated view to the assembled source. An assembly diagram can explain relationships even when it supplies no install tolerances.
Make the comparison
Trace each leader to a named OBJ object. Keep the assembled view beside the exploded one so the reviewer can find the same hinge before it is offset.
Worked record
The downloadable worksheet includes the records below and a blank row for your own project.
| Callout | OBJ object | Assembled location | Illustrated offset | Revision |
|---|---|---|---|---|
| 1 | B01_BASE | Lowest component | 0 mm | Study 01 |
| 2 | H01_HINGE | At arm pivot | '+20 mm in exploded drawing | Study 01 |
| 3 | A01_ARM | Rotates about source pivot | '+56 mm in exploded drawing | Study 01 |
| 4 | L01_HEAD | At the far end of the arm | 91 mm up in the exploded drawing | Study 01 |
Check the result
Reject a callout with no matching source object. The exploded distance is for legibility and must not be interpreted as a clearance.
Hand off the revision
Package the assembled model with the exploded view and part names. Mark the drawing offsets as illustration values.
Review question
Does the 20 mm hinge offset represent real assembly clearance?
The 20 mm is a display offset in the exploded drawing. Find H01_HINGE in the assembled source to recover its true modeled location. Actual clearance requires a separate engineering check.
