First Steps 2 (17)

Tekla (UK) Limited


This first exercise will involve the creation of a new model; the setting out andcreation of grids; working with views and; inserting basic steel and concretemembers into the model. Well also look at the different snapping options and theeffects they have.

Creating a Model

When creating a new model, there will be several options to choose from:

The Save in option is where the model folder will be saved, and is usually the default folder created during installation.

The Model nameis what this model will be called. Its a good idea to try and decide on a permanentname at this point which will not change. Changing the name of the model can be done afterwards, but

involves changing several file names.

Model templateallows you to start a model with a companys templates and settings predefined. This isespecially useful for sub-contractors. For this model we can set to (None).

Model type refers to whether the model will be a single or multi-user model. Multi-user is where severalpeople can work on the same model simultaneously. Here well be using Single-user.

After creating the model you should have in front of you a 3d view and a default grid.

The mouse pointer should be an arrow, which means its in selection mode. When the pointer is anarrow it means you can pick or select something with the left mouse button. After it is selected, clickingthe right mouse button will bring up a menu related to that item. The general rule in Tekla is that you can

select or pick something with one click, and bring up its properties with a double-click - as long asyoure in selection mode. This goes for objects in the model, views and also toolbar commands.

Controlling Views

Firstly, well see how the view navigation works. By holding the middle mouse button and dragging themouse you can pan the view around. By rotating the mouse wheel you can zoom in and out of where thepointer is placed. By holding Ctrl and the middle mouse button you can rotate the view around bymoving the mouse. Note - The point of rotation (the dashed purple circle) can be set at any time bypressing Von the keyboard and selecting a new point. You can also tick the Automatic RotationCentre option through the Tools>Options menu, which means a new centre of rotation is specified with

each press.

Workarea

The dashed box around the grid is the work area. In a view, you will only be able to see the parts that arewithin this workarea. This can be reduced at any time to allow you to work in a specific area, and alsoextended to include the whole model by choosing the Fit Work Area to Entire Model option from theright click menu of the view. The view needs to be selected to do this. A selected view wil l have a redborder around it, meaning it is the active view. Double clicking on the background of a view will bring upthe view properties, which allows you to change various options related to the view.

Creating a GridNow well alter the default grid. Double click the grid to bring up its properties. The Grid dialogue boxwill appear. The first three options are for the coordinates of the grid - or where you want the lines to be -and the second three allow you to label the grid lines. Note these must correspond to be correct whenusing the Create Views Along Gridlines tool. Change the coordinates and labels as shown and Modifythe grid properties.

Inserting Members

Now we can put into the model some basic members. Firstly well put in some concrete columns to formthe pad-stones. This command can be started by either clicking the toolbar icon once

or by selecting the option from the Modeling drop down menu (Modeling>Create ConcretePart>Column). Double clicking the icon or holding Shift when selecting from the drop down menu willbring up the Concrete Column Properties box.

Bring up the properties and change the profile in the Attributes tab to 1000*1000, and the top andbottom levels in the Position tab to -450 and -1000 respectively.

First Steps 6 (17)

Pressing OK orApply will then set these properties for this command. The only difference between thetwo is that OK will close the dialogue box and Apply will leave it open, allowing you to insert differentmembers into the model with the same command.

After starting a command the cursor will change to a cross, meaning that command is now active. Thetext at the bottom left corner of the screen will give you the instructions related to that command, in thiscase Pick position. Place a concrete column at each of the grid intersections. You should notice that thecursor is Snapping to various points of the grid with the shape of the yellow symbol changing. Thisshape represents the snapping point. What the cursor will automatically snap to is determined by whichsnaps are selected on the Snapping toolbar.

You can overide these and pick a specific point at any time by right clicking whilst in a command andselecting from the menu.

The command will remain active until you Interrupt, which ends the command and takes you back to

Selection mode. You can interrupt by pressing Esc or choosing from the right click menu.

First Steps 7 (17)

Tekla (UK) Limited


After interrupting, the cursor will change back to an arrow, allowing you to select any objects in themodel. Multiple items can be selected by holding Shift orCtrl when selecting. Shift will only allow you toselect, while Ctrl will also allow you to deselect. You can also use a window to pick multiple items. Thedirection which you create the window affects what is included in the selection left to right means thewhole object must be in the window, while right to left will include the object in the selection as long asany part of it is in the window.

Next well put in some steel columns. Double click the Create Column icon

or select the command from the drop down menu while holding Shift (Modeling>Create SteelPart>Column) to bring up the Column properties. Change the Profile to UC203*203*46 and the top andbottom levels to 6000 and -425 respectively, then press OK, which will set these properties to thecommand.


8/17

First Steps 8 (17)

Tekla (UK) Limited


Now place a column at each of the grid intersections over the pad stones, Interrupting when finished toend the command.

Next well alter the rotation of the four columns at grids B/1, B/4, C/1 and C/4. This can be done either bybringing up the properties of the member, changing the properties and pressing Modify, or by using theMini Toolbar. For this well use the Mini Toolbar, which allows you to easily modify objects and copytheir properties elsewhere. Selecting one of the columns should bring up a transparent menu just next toit, which will become solid as you hover the cursor over it.


9/17

First Steps 9 (17)

Tekla (UK) Limited


There will be several properties available to change. Click on the Position icon and move the green dotaround the outer circle 90 degrees, which you will see will rotate the column in the model.

Then double click the Copy properties icon and pick the other three columns.


10/17

First Steps 10 (17)

Tekla (UK) Limited


When an object in the model is selected, you will notice a yellow and purple dot appear at each end ofthe member.

These are the start and end points of that member, with the theoretical line between them the referenceline. When placing an item into the model, the point or points picked represent where this reference linewill be. The object can be positioned relative to this line by changing the various Position settings in theobject properties. Note it is good idea when modeling in Tekla to position the parts relative to thereference line where you would like the dimensions on the drawings to be from i.e. centrally in bothdirections for columns and bracings, and centrally on plan and below orBehind on elevation for beams.

Now well put some beams between the columns. Bring up the Beam properties (Modeling>Create SteelPart>Beam)

Change the profile to a UB305*165*40 and press OK.

We want to place the beams from the centre line of each column along the top level. It will make thiseasier to do by turning offSnap to geometry lines


11/17

First Steps 11 (17)

Tekla (UK) Limited


This will mean youre only able to snap to the reference lines of parts, not the part itself. It is a good ideato have this switched off when positioning the members as it greatly reduces the risk of picking a wrongpoint. With the beam command started, note the difference between this being switched on and off andwhat you can snap to.

Snap to geometry lines switched on

Snap to geometry lines switched off

With Snap to geometry lines switched off, place 3 beams between the columns along grid line 1, and 3between the columns along grid line A.


12/17

First Steps 12 (17)

Tekla (UK) Limited


Now interrupt, select the 3 beams on grid line 1, right click and select Copy.


13/17

First Steps 13 (17)

Tekla (UK) Limited


Copy the beams from grid 1 to grids 2, 3 and 4, then do the same for the beams on grid A, copying themto grids B, C and D.

Next well put some diagonal members in between grids 3 and 4, and C and D. Open the Beam

properties, change the profile to UB254*146*31 and press OK.


14/17

First Steps 14 (17)

Tekla (UK) Limited


Now we need to select a point to reference from, so with Ctrl held pick the top of the column on grid C/4.

Now we can enter a distance from this reference point. Pressing R on the keyboard will bring up theNumeric Location box.


15/17

First Steps 15 (17)

Tekla (UK) Limited


Here we can specify a distance from the point just picked. The first figure will be in the X direction andthe second in Y. If a Z direction is needed then this will come third, however if not there is no need toenter one. So we want to type in the box 2000,0. Pressing OK or the Enterkey will then make the firstpoint of the beam 2000 along grid 4 from the column.

Then do the same for the second point, this time entering values of 0,-2000 to set the second point 2000back along grid C from the same point.


16/17

First Steps 16 (17)

Tekla (UK) Limited


Instead of putting the other 3 members in the same way, it would be easier and quicker to copy themaround the centre point of the bay. Pick the diagonal member, right click and select CopySpecial>Rotate.

With the command started we now need to specify a point of rotation. This will be the centre point of thebay. Again, holding Ctrl, pick the top of the column on grid B/4. Now press R and enter the values2500,-2500. Press OK orEnterand the point of rotation should now be set, filling in the origin values onthe left of the Copy Rotate box.

Change the number of copies to 3, the rotaion angle to 90 and then press Copy. This will create 3copies of the beam around that point.
