⚙️ Naming Convention

General Format

year-system-subsystem-subassembly/nested subassembly-(part)-R# (human readable name)

Examples

Level	Example	Notes

Level	Example	Notes
System	`26-PTN`	Powertrain system
Subsystem	`26-PTN-10000 (Battery)`	Major subsystem
Subassembly	`26-PTN-10100 (BPS Subassembly)`	Within Battery subsystem
Nested Subassembly	`26-PTN-10110 (Connector Subassembly)`	Within BPS
Part	`26-PTN-10110-01-R1 (Connector Housing).sldprt`	Individual component

🧩 SolidWorks Assembly Naming

Assemblies should start with an underscore (_) to appear at the top of the file explorer.

Level	Example	Notes

Level	Example	Notes
System Assembly	`_26-PTN.sldasm`	No revision or name needed
Subsystem Assembly	`_26-PTN-10000 (Battery).sldasm`	Human-readable name required
Subassembly	`_26-PTN-10100-R1 (BPS Subassembly).sldasm`	Revision begins at subassembly level
Nested Subassembly	`_26-PTN-10110-R1 (Connector Subassembly).sldasm`	Nested assemblies also get R#
Secondary Assembly	`26-PTN-10001 (Battery Pack Secondary Assembly).sldasm`	Named as secondary assembly within subsystem

🧱 Parts Naming Convention

Parts must include the revision number R# and a human-readable name.

26-PTN-10110-01-R1 (Connector Housing).sldprt
26-PTN-10110-02-R1 (Lock Tab).sldprt
26-PTN-10100-01-R1 (Fuse Mount).sldprt
26-PTN-10100-02-R1 (Mounting Plate).sldprt

🧮 Reference Sketches & Equations

Reference sketches:
26-PTN-10000-REF.sldprt
Associated equations:
26-PTN-10000-REF-equations.txt

Reference sketches do not include revision numbers or human-readable names.

🗂 Subassembly Subfolders

Each subassembly folder must contain four standardized folders:

Folder	Purpose

Folder	Purpose
`_concept`	Early sketches, test parts, ideas
`_dwg`	Formal engineering drawings
`_fab`	CNC/3DP G-code, DXFs, fixtures, jigs
`_archive`	Old/deprecated designs or revisions
_sim	Design Study and Simulation Files
