When yu select an entity, fllwed by clicking n this tl, it pens the prperty windw f the entity. 2 IMPORT AUTOCAD MODEL INTO BUILDER In this sectin yu will imprt an existing flr plan in AutCAD dwg frmat t Mdeler prgram. The same prcedure applies, when yu imprt a drawing in DXF frmat. When imprted, the entities such as clumns and walls will be shwn by lines, plylines r plygns. In subsequent sectins, yu will learn hw t cnvert them t structural cmpnents. The plan view f the flr system yu will wrk n is shwn belw in a screen sht frm AUTOCAD.. 4

5 FIGURE 2-1: VIEW OF THE FLOOR PLAN IN AUTOCAD PROGRAM Imprt the AutCAD file int ADAPT Builder Open Builder and ensure that in the first screen (splash windw), yu select American as the system fr units, if yu wish t generate the mdel in American system f units. Otherwise select SI. In Builder, select File Imprt DWG/DXF. Brwse fr the AutCAD file f this Technical Nte. It is called TN246_US.dwg. Select the file. After a shrt while the AutCAD drawing will appear n the Mdeler screen. If the drawing is nt displayed, click n the Zm-Extents tl t have the imprted drawing enlarged and displayed centered n the screen. 3 CALIBRATE THE IMPORTED FILE Each time yu imprt a drawing t Builder frm AutCAD yu shuld specify ne f its dimensins, in rder t scale the drawing t the crrect size, befre cnverting it t a structural mdel. In the nrmal curse f mdel generatin, the prgram will guide yu d s 3. Yu will be asked t select tw pints in the mdel and specify the distance between them. The prgram will scale the remainder f the file t match the distance yu have specified. It is advisable t select pints that are far apart, and use snapping tls. This increases the accuracy f the structural mdel yu create. 3 If yu miss this step, yu can always yu can activate the calibratin tl by selecting the menu item Calibrate Drawing frm the Tls pull-dwn menu. Als, yu can scale a structural mdel, nce yu have generated it. 5

Yu will be asked at the bttm f the cmputer screen n the cmmand line t enter the infrmatin needed fr calibratin. Use the snap tl during calibratin. Cnsider tw pints n the plan, where yu knw the distance between them. Observe the length f the flr slab in Fig. 3-2 (114 ft, 49m). This is a gd dimensin t select FIGURE 3-2 PLAN CLOSE UP SHOWING LENGTH OF THE FLOOR With the snap t perpendicular n, click n the start pint f the calibratin line (Fig. 3-3a); next, click n the end pint f the dimensin line (Fig. 3-3b); bserve the prmpt at the bttm line f the cmputer screen and enter the distance between the pints (114 ft, 49m); and clse by pressing Enter key. The abve re-sizes the drawing t the scale yu have selected. Center the mdel n the cmputer screen, by pressing the zm extents tl. 4 Each time yu imprt a drawing t Builder frm AutCAD yu shuld specify ne f its dimensins, in rder t scale the imprted drawing t the crrect size. Yu will be asked t d s by the prgram by selecting tw pints in the mdel and specify the distance between them. It is advisable t select pints that are far apart and snapping tls t create an accurate mdel f the structure. 6

In mst cases it is acceptable t select N. In the case which yu will be imprting several DWG drawings int the same mdel and have them autmatically superimpsed, yu wuld select Yes 5. In this case select N. At this stage, the imprted mdel will lk as shwn belw. FIGURE 4 1 VIEW OF IMPORTED MODEL 5 If yu plan t imprt several dwgs int ne file and want them t be psitined exactly where yu want them, such as exactly ver ne anther, yu shuld change the rigin f the crdinate system t a pint chsen by yu. Say Yes and fllw instructins. Yu can change the rigin at a later stage if need be frm Tls -> Change Prject Origin. 7

8 5 AUTOMATIC CREATION OF POLYGONS The bundary f slabs, walls, clumns and penings are in frm f plygns. It is pssible that the dwg yu have imprted des nt delineate the utline f all f these entities by plygns. In many instances, the Mdeler can assist yu t detect the bundary f the entities that are intended t represent structural cmpnents, such as clumns. This is the first step tward the transfrmatin f graphical entities f the drawing yu have imprted t structural cmpnents f Mdeler. In this step, yu will use the prgram t cnvert t plygns as many f such ccurrences as the prgram can detect. In Builder, select Build Display Mdeling Tlbars, this will display all the tlbars yu will be using t cnvert the 2D entities int 3D structural cmpnents. Mst f the peratins will be carried ut using the tl bars in Fig One lists the tls that changes (transfrms) a drawing entity t a structural cmpnent. The ther cntains the tls fr creating (building) new structural cmpnents. (a) Transfrmatin Tlbar (b) Creatin Tlbar FIGURE 5-1 STRCUTURAL COMPONENT GENERATION TOOLS Click n Transfrm Plygn Tl. The prgram prmpts the fllwng, indicating that it culd lcate 36 instances where cnnected lines culd be cnverted t plygns FIGURE 5-2 Next yu will display the plygns generated in rder t cnvert them t structural cmpnents. T speed up the cnversin, yu will hide frm display the items that are nt necessary and limit the display t the plygns fr cnversin t structural cmpnents. Frm the Layers Setting tl pen the layers dialg windw. Click n the buttn All Layers Off t turn ff all the layers. Lcate the layer Plygns_Frm_Lines, as shwn in Fig This will display the plygns generated by the prgram (Fig. 5-4). Nte that sme f the plygns are readily identifiable as intended t represent structural cmpnents, such as clumns and walls. The plygns that were in the riginal dwg imprted, if any, will nt be displayed n this view. 8

9 FIGURE 5-3 FIGURE 5-4 DISPLAY OF POLYGONS GENERATED BY THE PROGRAM 6 SET FLOOR TO FLOOR HEIGHTS The entities shwn n the screen at this time are 2D. There is n height assciated with them. Yu need t define a default value fr the length f these cmpnents, such as clumns, abve and belw the flr yu are creating. This is dne by yu defining a flr-t-flr distance between the current flr that yu are mdeling and the flrs abve and belw. This will result in the clumns and walls yu create t extend initially frm the current level t the levels abve and belw. Yu can later change the length f each f these cmpnents, yu need be. Frm creatin tlbar click n Level Assignment Tl. The fllwing windw pens. Nte that the distance between the current plane and the ne abve and belw it is given at 10 ft (3m). Accept the values displayed and clse the windw. Obviusly, yu have the ptin t change these, where the flr t flr heights are different. 9

10 FIGURE 6-1 FLOOR-TO-FLOOR HEIGHT ASSIGNMENT DIALOG WINDOW 7 TRANSFORMATION OF GRAPHICAL ENTITIEYS TO STRUCTURAL COMPONENTS At this step, yu will cnvert the plygns that represent structural cmpnents, such as clumns, t structural cmpnents. It is best t change the display t blique view t better see the 3D cmpnents that yu transfrm. D the fllwing. Click n the Tp-frnt-right-view. The fllwing appears. FIGURE 7 1 OBLIQUE VIEW OF THE PLOYGONS GENERATED Select a plygn that represents a wall, such as the ne shwn belw. 10

11 FIGURE 7 2 SELECTION OF A POLYGON THAT REPRESENTS A WALL Click n the Transfrm Wall tl t create a wall at this lcatin, with a crss-sectinal area defined by this plygn and a height defined by the flr t flr height tl yu used abve. The fllwing shws the view f the wall created. FIGURE 7 4 VIEW OF WALL TRANSOFRMED FROM A POLYGON Check the prperties f this wall by duble clicking the left muse n it. The prperty windw f the wall pens (shwn belw). Examine the values f the prperty assigned t the wall. In this Technical Nte tutrial, we are nt ging t change the wall prperties, such as it material and height. 11

12 FIGURE 7-5 PROPERTY WINDOW OF WALL Clse the prperty bx by clicking n the tp right crss n it. Hwever, if yu change any f the wall s prperties, yu need t click n the cnfirmatin tl t validate yur change. Similar t the transfrmatin f the wall abve, select the plygn at the bttm left f the display and transfrm it t a clumn as shwn belw. FIGURE 7 6 DISPLAY OF A TRANSFORMED COLUMN Transfrm the rest f the walls by selecting the rest f the plygns that represent walls as detailed belw: Keep the cntrl key depressed, while yu click n the entity that yu wish t add t the selectin. If yu make a mistake and select an entity that yu did nt intend t be part f the list, keep the cntrl buttn depressed and click ne mre time n the item that yu want t de-select. 12

13 (a) Display f plygns intended t be clumns (b) Display f cnverted clumns FIGURE 7 7 TRANSFORMATION OF WALLS Next select the plygns that are intended t be transfrmed t clumns. Again, keep the cntrl key depressed fr adding t the selectin. If yu make the wrng selectin, click n the entity ne mre time t deselect it. When all the clumn plygns are selected, the screen lks as shwn belw. 13

14 (a) Display f plygns representing clumns (b) Display f clumns and walls transfrmed frm plygns FIGURE 7 8 TRANSOFRMED COLUMNS AND WALLS The fur rectangular plygns n the bundary f the image are each a balcny. Select the ne at the bttm left and change it t a slab regin using the Transfrm t Slab Tl. 14

15 FIGURE 7-9 CONVERSION OF ONE POLYGONE TO BALCONY SLAB REGION The balcnies are 7 (180 mm) thick and are 1 (25mm) lwer than the flr slab at the interir f the building. Next we define the thickness f this balcny and its drp with respect t the rest f the flr system. Once yu define the prperties f ne entity, such as the balcny slab in this case, the subsequent entities that yu transfrm will assume the same prperty. 6 Duble click n the transfrmed balcny t pen its prperty windw (shwn belw). FIGURE 7-10 PROPERTY WINDOW OF BALCONES 6 If the next entity yu transfrm r create des nt assume the prperties f the last entity f the same kind yu transfrmed, d the fllwing starting frm Settings pull-dwn menu Settings -> General Settings and check mark the item Use the prperties f the last mdified cmpnent f the same type as default. 15

16 In the prperty windw f the slab regin pened, change the slab thickness t 7 (180mm). Click n the Lcatin tab, and change the Vertical ffset t 1. This will bring the balcny 1 (25mm) belw the reference plane (flr slab level at the interir f the building). Later, we will generate the main flr n the reference plane. FIGURE 7 11 PROPERTY WINDOW OF BALCONY SLAB Select the remainder three plygns that represent balcnies and cnvert them t balcnies as shwn belw. FIGURE 7 12 CONVERSION OF REMAINDER OF BALCONIES Open the prperty bx f ne f the balcnies cnverted abve and verify that its slab thickness is 7 and it is ffset by 1 (25mm). If this is nt the case, make the necessary crrectin in the prperty windw f the balcny pened and cnfirm yur entry by clicking n. 16

17 There are three penings in this flr system. Click n ne f the plygns that represents an pening fr its transfrmatin. Yu will nte, as shwn in the figure belw, that the selected plygn is a triangle. The prgram did nt recgnize the bundary f the pening as the plygn that represents the utline f the pening. Leave fr nw the cnversin f these plygns t penings. At a later stage, yu will create them using the creatin tl. FIGURE 7-13 CONVERSION OF POLYGON TO OPENING By nw, yu have handled all the plygns that were created thrugh the Transfrm Plygn tl. The dwg file imprted may have included plygns that are nt displayed n this view. If any, yu will cnvert thse plygns, when ther layers are turned n. View the cmpnents created s far fr the visual cnfirmatin f the validity f the wrk dne. Click n the View Mdel tl t btain a 3D slid display f the cmpnents generated. Rtate the assembly f the cmpnents and visually cnfirm their validity (Figure belw). FIGURE D VIEW OF STRUCTURAL COMPONENTS 17

18 8 CREATION OF STRCTURAL COMPONENTS T create the remainder f the structural cmpnents frm AutCad drawing, yu have t trace each. Yu will find, the tls that are available fr yu t make the tracing and cnversin are fast and simple. The best is t start by ging thrugh the layers that were imprted frm AutCAD, and select nly thse layers fr view that include the cmpnents yu plan t create. This may nt be practical in all cases, since sme layers may have mre than what is required, r may nt have all that yu need, as is the case in the dwg we have imprted. D the fllwing Exit the 3D slid viewer Display the mdel n plan view Open the Select layers dialg windw (shwn belw). FIGURE 8 1 SELECT LAYERS DIALOG WINDOW Turn all layers n. Turn DIM and TEXT layers ff. Click n OK t g back t the mdel. The plan shwn belw appears. FIGURE 8 2 PARTIAL VIEW OF THE FLOOR SYSTEM 18

19 Yu will use the tls listed belw t trace the lines define the bundaries f slabs and penings: Snap tls, in particular snap t intersectin, snap t end, snap t nearest Insert pint Mve pint Delete pint In navigating ver the drawing t pan and zm yu can use the muse middle buttn as fllws: Rll the middle buttn t zm in and ut; and keep the middle buttn depressed and mve the muse t pan. Yu will nw create the main slab f the flr system by tracing its utline n the dwg drawing. Click n the create slab tl frm the Build Tlbar belw: Turn all the snap tls ff frm the tlbar belw: FIGURE 8-3 SNAP TOOLBAR Click n the snap t intersectin t turn it n. Starting frm ne crner f the slab utline, such as tp left, bring the cursr clse t the slab crner and left click, when the snap sign yellw X shws up (Fig. belw). FIGURE 8-4 SNAP TO INTERSECTION AT THE CORNER OF SLAB OUTLINE Cntinue tracing the utline f the slab frm vertex t vertex, each time click the left muse when the cursr snaps t an intersectin pint. In the curse f yur tracing, it is likely that yu wuld miss a pint, r click at the wrng psitin, r have t quit the tracing prematurely. This is nt critical t yur wrk, since yu will subsequently crrect the mistakes thrugh the editing 19

20 tls. As an example, the figure shwn belw illustrates a partially cmpleted slab utline with several f the pints nt crrectly snapped at the slab utline. In additin, the slab utline drawn des nt cver the entire slab. FIGURE 8-5 INCOMPLETE CREATION OF SLAB BOUNDARY T crrect a pint that is nt snapped crrectly n the slab utline, such as the tw pints shwn in the figure abve, d the fllwing. Zm in n the lcatin Select the slab yu have created (figure belw) FIGURE 8-6 INCOMPLETE SLAB BOUNDARY SELECTED FOR EDITING 20

21 Make sure that the cursr is in pick mde (indicated by a small square) The vertices f the slab yu have created s far are revealed with small squares. Bring the cursr ver ne such vertex that needs crrectin, pick it (left muse), mve it clse t the crrect lcatin until the snapping sign shws, left click the muse t lck the slab vertex at the crrect psitin. FIGURE 8-7 VERTEX OF A SLAB BOUNDARY BEING SNAPPED TO COORECT LOCATION FIGURE 8-8 VERTEX OF A SLAB BOUNDARY SNAPPED TO COORECT LOCATION In the curse f cmpleting and editing the utline f the slab, in additin t insert pint yu are likely t use the und tl, if a pint yu have created is at the wrng 21

22 lcatin; use delete pint, add pint, and mve selected pint. Cntinue with the tracing f the slab utline, until cmplete as shwn belw. FIGURE 8-9 VIEW OF COMPLETED SLAB BOUNDARY View the structure in 3D viewer t visually cnfirm the wrk yu have dne s far. The 3D mdel shuld lk as shwn belw. FIGURE 8-10 VIEW OF COMPLETED SLAB BOUNDARY Next create the penings by clicking n the create pening tl, while the snap t intersectin tl is n. Trace the utline f each pening. When cmplete, the structure will lk as shwn belw: 22

23 FIGURE 8-11 VIEW OF COMPLETED STRUCTURE Check the slab thickness and its elevatin by pening the slab s prperty bx (duble click n its bundary). Yu will nte its slab thickness is 7 (180mm) which is the default yu had fr the balcny. Change the slab thickness t 8 (200mm). Next frm the lcatin tab, change the vertical ffset t 0 in, This will establish the psitin f the slab 1 (25mm) abve that f the balcny. Click n tl t validate yur crrectin. Clse the slab s prperty bx. 9 ESTABLISH COMPONENT CONNECTIVITY The structural mdel yu have created is cmplete and ready t be validated. Hwever, the slutin yu will btain will be mre accurate, if the tp f the walls and clumns are shifted belw the slab, as ppsed t have them extended t the tp f the slab in the mdel s current cnditin. T adjust the cnnectivity f the clumns and walls t the slab, d the fllwing: Frm Build pull dwn menu ->Preprcessing -> Establish Cmpnent Cnnectivity. View the mdel and verify that the clumns and walls terminate at the sffit f the slab. 10 CLEAR THE DISPLAY FROM NON-RELATED ENTITIES At this stage, it is a gd idea t clear frm the display f the structural mdel frm the unnecessary lines, text and infrmatin, befre prceeding t the validatin f the mdel yu have generated. Each f the structural cmpnents yu have generated is placed in its wn layer. The layers generated by the prgram fr yur current mdel are: Current_plane_clumn Current_plane_pening Current_plane_slab_regin Current_plane_wall D the fllwing: Open the layer dialg windw (shwn belw) Click n the Label tab t rganize the list f layers alphabetically 23

24 Turn all layers ff Turn n nly the cmpnent layers listed abve Press OK FIGURE 10 1 SELECT LAYER DIALOG WINDOW The mdel yu have created shuld lk like the image belw FIGURE 10 2 COMPLETE PLAN OF THE STRUCTURAL MODEL 11 VALIDATE THE STRUCTURAL MODEL This stage f the wrk is applicable if yu plan t use FLOOR-Pr prgram fr a finite element analysis and design f the structure. If yu plan t use the mdel t generate data fr ADAPT-PT r ADAPT-RC, the fllwing is nt applicable t yur wrk. Fr exprt t ADAPT-PT/RC the validatin is achieved by a clse visual examinatin f the mdel generated. Fr analysis and design using FLOOR-PRO, befre mving ahead with the rest f data input, such as definitin f material prperties, lads and mre, it is imprtant t validate yur wrk. The validatin is dne by btaining a slutin fr selfweight f the structure using the default values f the prgram and visually examining the deflected shape f the flr system. A clse scrutiny f deflected shape f a flr system under selfweight, can reveal many errrs in mdel generatin. 24
