BlenderBIM과 Revit 비교 (blenderbim.org/blenderbim-vs-revit.html)
Revit은 현재 시장 점유율에서 가장 일반적인 BIM 작성 도구입니다. 그럼에도 불구하고 반드시 가장 강력한 기하학적 모델링 패키지는 아니며 반드시 가장 강력한 BIM 데이터 저작 도구도 아닙니다.
- 기하학적 모델링 능력
Revit은 모델링 기능이 매우 제한되어 있기 때문에 모델링을 위해 Revit과 Blender를 비교하는 것은 다소 불공평합니다.그러나 Revit에는 몇 가지 장점이 있습니다.
| Modeling Concept | BlenderBIM | Revit | Notes |
| Solid extrusion and void modeling | Supported | Supported | 이것은 Revit이 가지고있는 유일한 지오메트리 편집 기능입니다. |
| Polygonal modeling | Supported | Not supported | |
| NURBs, Bezier, and Surfaces | Supported | Not supported | |
| Point cloud manipulation | Supported | Not supported | |
| Sculpt modeling | Supported | Not supported | |
| Parametric modeling | Supported | Supported | 두 도구 모두 파라 메트릭 모델링을 지원하지만 다른 방식으로 수행되며 다른 사고 방식이 필요합니다. |
| Domain specific modeling | Supported | Supported | Revit의 모델링 도구는 도메인별로 매우 다르므로 제한이 있습니다. 블렌더의 도메인 특정 모델링 기능은 Archipack addon을 통해 사용할 수 있습니다. |
| Algorithmic modeling | Supported | Supported | Revit은 Dynamo를 사용하여 이를 수행 할 수 있으며 Blender는 Sverchok를 통해 이를 수행 할 수 있습니다. |
- IFC 저작
BIM 데이터가 Autodesk 에코 시스템 외부에서 유용 할 수 있도록 실제로 올바르게 작성되었는지 확인 하는 것이 우선 순위가 되거나, 건물이 건설 된 후 3 년 이상 지속될 수 있도록 하려면, IFC를 다음과 같이 작성하는 방법을 찾아야합니다. 이 비교 테이블은 IFC 스키마에서 지원하는 다양한 개념의 목차를 기반으로 합니다. 요약하면 BlenderBIM은 72/105 개념 (69 %)을 지원하고 Revit은 39/105 개념 (37 %)을 지원합니다.
