5 Bentley Architecture

6 Bentley Architecture The focus of this Bentley Building application enables designers to maintain a strategy that addresses various essential project life cycle needs, including: Space planning and mass modeling determinations that occur in the beginning stages of a project. Production-oriented activities that occur during modeling such as placement of walls, doors, and windows. Drawing, schedule, and report extraction that occurs throughout the life cycle of a project, and beyond.

7 Building Objects Architecture Toolbox

8 Objects in BA General type Contour, space, column grid Column Wall Door Window Floor Roof Stair Toilet, shelving User defined type Curtain walls Hand rails Plumbing fixtures Toilet accessories (Unlimited) Additional custom object

9 Datagroup / Catalog Item definition for BA

10 DataGroup Catalog Editor in BA

11 Management of User-defined Object 1. Placement 2. Datagroup Definition 3. Edit Datagroup Catalog Items 4. Modeling the objects using Parametric Cell Studio 4-1. How to create parametric objects & behaviors 5. Again: Placement to the model

12 1. How to place embedded custom objects 1. Architecture Modeling Toolbox 2. Fixture, Furnishing & Equipment menu 3. Place User Defined Type dialogue box NEXT: How to add a new object type in this list? 4. Select Type of User Defined Objects in the list 5. Select sub Items and modify their properties

13 2. Datagroup Definition 1. Run Datagroup Definition Editor in Bentley Building Applications, and add new definition files. Also create their properties. NEXT: How to add a new item in this definition? 2..xsd files are created in datagroupsystem folder

14 3. Edit Datagroup Catalog Items 1. Run Datagroup Catalog Editor, and add new type and their items. Also create their properties. NEXT: How to make geometric models? 2..xml files are created in datagroupcatalogs folder

15 4. Modeling the objects using PC Studio the kernel 1. Using PC Studio, model the objects (cell). And publish (compile) them to *.paz files

16 5. Place a new custom (user-defined) object 1. Select and Modify the object items 2. Place the User Defined Object in Bentley Architecture

17 Parametric Cell Studio

18 Parametric Cell Studio (PCS) Stand alone application for parametric cell modeling A little bit different interface compared with Microstation Powerful yet so simple parametric design tool

19 How to build parametric custom object for BA Mullion component Components assembly of Frame and Path XY Plane Combination of Constraints on YZ Plane ZX Plane Sophistication of Condition / Segments / Components and publication (compile) for Bentley Architecture

20 Special features of PCS Define several components using simple drawing tool Assembled components can be defined another component Assembled components inherit all constraints of each component Path and reference line based solid modeling Several defined segments take charge of layer function and fulfill the roles of translation to BA Substantial object-oriented concept and property inheritance >> perform a kind of power copy

21

22 Component-oriented approach Sub components for other components / reference line 1. Basic Section 4. Main Assembly 5. Final component 2. Basic components 3. Sub components Various applications

23 Case Study

24 Case study 1. Kawneer 2800 TRUSSWALL 2. Curved and Bended Curtain Wall Apply selective constraints for parametric modeling Focusing on the parametric behavior / modeling

25 Case study #1. Kawneer 2800 TRUSSWALL

26 Modeling process Section / basic drawing Components modeling Define path / reference line in each plane Sweep / extrude / array along path for assembly Constraints modeling in each plane Define as a final model >> a new component

27 Constraints on XY Plane Distance & relation between the points on the path line Distance of horizontal mullion Angle of path line and mullion Angle of path points (mullion s location points)

28 Constraints on XY Plane Axono view 1. Angle of Mullion to path 1. In case of A_1 = 360 degree 2. Angle of Path line & point A_1 = 350 = A_2 = A_3 3. Mullion s Horizontal Distance ML_1 = 4 00 = ML_2 = ML_3 4. Array distance of Mullions As same as ML_1 2. In case of ML_1 = 3 Array distances were changed simultaneously

29

30 Constraints in YZ Plane 3. Array of Web following Mullion Height & their distance 1. Height of Vertical Mullion Component Assembly 2. Same Height constraint for rear mullion

31

32 Constraints in ZX Plane 1. Height & Relation of Intermediate Horizontal 2. Shape Sweeping through the path

38 Inaccuracy of angle: 10 degree Solution: 1. Elaborate parameters / conditions 2. Condition control method Example of Kawneer system: Contextual placement by angle

39 Constraints of basic mullion assembly 3. Array of Web following Mullion Height & their distance 1. Height of Vertical Mullion Component Assembly 2. Same Height constraint for rear mullion

40 Constraints of curved arc angle / distance 1. Angle of Mullion to path 1. In case of A_1 = 360 degree 2. Angle of Path line & point A_1 = 350 = A_2 = A_3 3. Mullion s Horizontal Distance ML_1 = 4 00 = ML_2 = ML_3 4. Array distance of Mullions As same as ML_1 2. In case of ML_1 = 3 Array distances were changed simultaneously

41 Constraints for Horizontal mullion & Edge cutting 1. Height & Relation of Intermediate Horizontal e.g: HM_Height = (Main.height / 4) M.offset 2. Paralleled cut of horizontal mullion by bended angle w.g: bend.angle = (360-curved.angle)/2

42 Horizontal Mullion B d a b C c Curtain wall path A Length: a = b = c = d Angle: Center point of arc A = B C = B/2 = A/2

43 d B a b C A Length: a = b = d Angle: Center point of arc A = B C = B /2 = A /2

44 d a B C b A Length: a = b = d Angle: Center point of arc A = B C = B /2 = A /2

45 Constraints for angled cut A2 A1 L1 B d a b C HM_A1 A2 = 540-A1 A1 = 270+(360-HM_A1)/2 A

46 Constraints for angled cut

47 Curved 2800 TRUSSWALL component could be defined another component using its variables e.g. curtainwall system using different angle, distance and different anchor point Constraints in PC Studio - Length - Angle - Semi diameter of circle - Coincidence on a point or path line - Sweeping along path - Array along path - drop first or last array - distance of array

53 From Parametric Cell Studio To Bentley Architecture

54 Extra issues for *.paz format Publication Model3d, Plan2d, or similar segments in PC Studio support the contextual display in Bentley Architecture model Segment names should be provided accurately to BA Performance: sometimes PCS shows not a good result due to file size, complexity and so on. Well-defined parametric cells are required to prevent inadequate parameters, e.g. limitation of variables (also related with performance issue)

55 Contextual Display in BA 1. 2D drawing 2. 3D model 3. 3D rendered model Contextual Display is determined by whether the context is a drawing (1) or a model (2,3)
