# Simple CAD Examples
|
||||
|
||||
These examples cover compact part generators that are not already represented
|
||||
by the benchmark suite.
|
||||
|
||||
The remaining prompts are:
|
||||
|
||||
1. Cylindrical spacer sleeve with a central through-bore and rounded rim edges.
|
||||
2. Square mounting block with a vertical through-hole and two side clearance holes.
|
||||
3. Gusset plate with a triangular web, base holes, and softened perimeter edges.
|
||||
4. Rectangular clamp block with a split slot and two transverse screw holes.
|
||||
5. Shaft collar with a central bore, radial set-screw hole, and chamfered faces.
|
||||
6. Pulley wheel with a central hub, outer groove, and circular through-bore.
|
||||
7. Spur gear blank with central bore, raised hub, and simplified perimeter teeth.
|
||||
8. Flywheel disk with central bore, annular rim, and lightening holes.
|
||||
9. Cam follower roller with central bearing bore and rounded outer profile.
|
||||
10. Small enclosure cover with raised rim, corner screw holes, and shallow recessed center.
|
||||
11. Cylindrical cap with hollow interior, top boss, and rounded external edges.
|
||||
12. Retainer plate with elongated slot, two circular holes, and chamfered perimeter.
|
||||
13. Keyed shaft hub with central bore, keyway slot, and bolt-hole pattern.
|
||||
14. T-slot slider block with central channel, side relief cuts, and mounting holes.
|
||||
15. Mounting plate with central circular cutout, elongated side slot, four corner holes, and rounded edges.
|
||||
16. Basic shape mating test fixture for assembly-helper surface and collision checks.
|
||||
|
||||
The flat rectangular plate, circular flange, L-bracket, U/clevis bracket, and
|
||||
open-top electronics enclosure examples are intentionally omitted here because
|
||||
`models/benchmarks/` already carries richer versions.
|
||||
|
||||
## Files
|
||||
|
||||
- `*.step`: Primary STEP files for each simple example.
|
||||
- `*.py`: Python generators for each example.
|
||||
- `simple_model_library.py`: Shared build123d implementation helpers used by the generators.
