GeomCatalog の詳細を見るV2.2 Hole Check
STEP / IGES モデルの通常穴・座グリ穴・皿穴を条件付きで抽出し、期待件数との差分を確認できます。Extract normal holes, counterbore holes and countersink holes from STEP / IGES models by condition and compare detected counts with expected counts.
Supported hole types
- Normal holes based mainly on cylindrical geometry
- Counterbore holes with a larger counterbore and smaller pilot hole
- Countersink holes with a conical entrance shape
- Faces that form the same hole are grouped and handled as one feature where possible
Result review
- Compare expected counts with detected counts and review OK / NG
- Review hole type, through / blind status, pilot diameter, depth, counterbore diameter and countersink angle
- Hole totals and individual hole results are integrated into the standard results screen
- Save results, reopen them for the same model and export lists to CSV
| Target range | Full model / selected part / selected subtree / currently visible range |
|---|---|
| Main conditions | Hole type, expected count, pilot diameter range, through / blind / unknown, counterbore diameter and depth, countersink outside diameter and angle |
| Hole check support | STEP / IGES only. STL is not supported for V2.2 hole checking. |
