Tekla Structures – Grids

So that you can easily locate objects in your model, we strongly advise that you create a modular grid. The Tekla Structures grid is shown on the view plane by dash-and-dot lines. You can have more than one grid in a model. You may want to create a large-scale grid for the entire , and smaller grids for some detailed sections. Grids are rectangular. You can also create single grid lines and attach them to an existing grid.


To position objects in a radial or circular pattern:

•      Create one grid line and use the Edit > Copy Special > Rotate command to copy it.

•      Use lines and circles

You can pick grid lines and grid line intersections.
Grid properties
To access the Grid dialog box, do one of the following: • Click Modeling > Create Grid….
Use the Select grid switch and double-click an existing grid.
Grid coordinates The x and y coordinates of a grid are relative. This means that the entries for x and y are always relative to the previous entry. The z coordinates are absolute meaning that entries for z are absolute distances from the work plane origin.

There are two ways to enter the x or y coordinates of grid lines:

•     individually, e.g. 0 4000 4000, or

•     several grid lines with equal spacing, e.g. 0 2*4000. Both create three lines with the spacing of 4000.

Use a zero at the start to represent a grid on the 0,0 coordinate and spaces as separators for coordinates. You can have a maximum of 1024 grid characters in the co-ordinates field.
Labels Labels are the names of the grid lines shown in views. The names in the X field are associated with the grid lines parallel to the y axis and vice versa. The Z field is for the names of levels parallel to the work plane. If you wish, you can leave the label fields empty.
T When working with very large grids, having the grid labels always visible might slow down Tekla Structures. To hide the grid labels when you zoom in, use the variable XS_ADJUST_GRID_LABELS.
Line extensions You can also define the Line extensions over the given grid coordinates and the Origin of the grid.

Magnetism You can make grids and grid lines act magnetically so that the objects on the grid lines follow if you move the grid line.

To bind objects to grid lines, select the Magnetic grid plane checkbox.

In the Extension for magnetic area field, enter a distance from the grid line to extend the area within which the objects are bound to the grid lines.

Grid line properties
You can also create and modify single grid lines. To access the Grid Line Properties dialog box:
Use the Select grid lines switch \Wi and double-click an existing grid line.
Working with grids
Automatic grid When you create a new model, Tekla Structures automatically creates a grid and a view according to the saved standard properties.

2.    Fill in the properties described in Grid properties .

3.     To create the grid, click the Create button.

Tekla Structures prompts you to pick the origin when you create the grid. Pick a point in a view, and the coordinates of the picked point appear in the Grid dialog box as X0, Y0, and Z0. If you do not pick, Tekla Structures positions the origin according to the values you entered for X0, Y0, and Z0.

Creating grid lines

To manually create a grid line:

1.    Click Modeling > Add Grid Line.

2.    Select an existing grid to which to attach the grid line.

3.    Pick the starting point of the grid line.

4.    Pick the end point of the grid line.

Using select on grids

Tekla Structures includes separate select switches for entire grids and single grid lines. The active select switch affects the objects you can select, modify, and delete.

Introduction               There are several ways to create views in Tekla Structures. For example, you can create views:

•     of the entire structure

•     of selected part(s) and component(s)

•     along the grid lines

Each view has properties which define its appearance. You can change the appearance of a view after you create it so choose the creation method that suits you. This section describes the view-specific properties. You can open the view properties dialog box for each view, to view or modify the properties.

T Unnamed views disappear when you close them.

You can have up to nine views on the screen at the same time. If you try to open more than nine views, Tekla Structures displays a warning. If the view does not appear, check how many views you have open.

To switch between views, press Ctrl+Tab.

Getting Started
View plane
Basic view plane Each view has a view plane on which the grids are visible and points are represented as yellow crosses.

Basic views are those parallel to the global basic planes, i.e. xy, xz, and zy. In basic views two axes always define the view plane and they appear in the plane name. The third axis is perpendicular to the view plane. It does not appear in the plane name. In the basic plane view, the model is shown from the direction of that third axis.

The view plane options for basic views are:

View plane coordinate

Other views

For basic views, you also define at which distance from the global origin the view plane is in direction of the third axis. The view plane coordinate equals this distance.

For view types other than basic views, you define the view plane and coordinate by picking points, e.g. With three points, or they are defined automatically according to the chosen creation method/command, e.g. To work plane.

You can change the view plane by moving it like any other object. Click anywhere on the plain background, right-click and select Move Special > Linear… from the pop-up menu..

Moving the view plane
■s Moving a view plane may result in a situation such that view and work area do not intersect and thus nothing can be seen in the window.
View properties
Naming views            Tekla Structures numbers views in order of creation, so you do not have to give each view a

specific name.

You should give a view a unique name if you need to open it in later sessions. When you exit the model, Tekla Structures only saves named views. Tekla Structures does not save unnamed views when you close them.

J? In multi-user mode, it is very important to give views unique names. If several users have different views with the same name, the view settings of one user may randomly override the settings of another user.
Getting Started
View type

The view type defines the appearance of the view. It also affects what methods you can use to rotate the model. The view type options are:

•     Wire frame

Objects are transparent and their outlines are displayed. As the wire frame views use line graphics technique, redrawing views is quick.

•     Rendered

Objects look more realistic because they are non-transparent and their surfaces are displayed as shown in the illustrations below. However, you can also choose the Wireframe or Shaded Wireframe option in the rendered views. Rotating the model in the rendered views is very convenient with the mouse.


In rendered views, you can define how Tekla Structures displays parts and component objects separately. The following options are available:

•     Wireframe

Part outlines are displayed, surfaces are not, i.e. parts are transparent.

(In this example, component objects are displayed as Rendered.)

•     Shaded Wireframe

Part outlines are displayed. Parts are transparent, and their surfaces are shaded.

(In this example, component objects are displayed as Rendered.)

Hidden Lines

Parts are not transparent, i.e. underlying parts are not visible. Part surfaces are not displayed.


Part surfaces are displayed, i.e. parts are not transparent.

Rendered (Dark Colors)

Parts are not transparent. Part outlines are displayed with brighter color, and part surfaces with darker color than in the Rendered option.

•7 In rendered views, use the shortcuts Ctrl+1…5 and Shift+1…5 to set the desired representation for parts in the model and components.
View angle Projection

If you choose the rendered view type, the projection can be:

•      Orthogonal

All objects are of equal size (no perspective). When you zoom, text and point size remains the same. In addition, the zoom remains on part surfaces.

•      Perspective

Distant objects appear smaller than close ones, as do text and points. You can zoom, rotate the model, or fly through it.

Views can be:

•      Plane


Use the shortcut Ctrl+P or click View > Switch to 3D / Plane to switch between 3D and plane view.
Rotation Rotation is view-specific. You can rotate the model in 3D views using the mouse and keyboard, or by defining the rotation angle in the View properties dialog box. You can specify rotation angles around the z axis and around the x axis.
View depth Every view has depth, which is the thickness of the displayed slice of model. You can define the depth separately upwards and downwards from the view plane. The objects within the displayed depth and the work area are visible in the model. However, objects created after the view are visible also outside the view depth
Defining grid view properties
Number of views

Grid views are views along the grid lines. Before creating grid views, you can define how many views Tekla Structures will create, how it will name the views, and which view properties it will use.

There are four options for the number of views:

•      None Tekla Structures does not create any views.

•      One (First) Tekla Structures only creates the view closest to the grid origin.

•      One (Last) Tekla Structures only creates the view furthest from the grid origin.

•      All Tekla Structures creates all views in grid planes in the relevant direction.

View names consist of a prefix and a grid label, e.g. +3000. If the View name prefix field is left empty, no prefix is used. Tekla Structures adds a dash and a running number to the view name if view names are otherwise identical.

Each view plane has its own view properties. You can load the properties from the current view properties with the option or from saved view properties. The Show… button displays the view properties.

Getting Started
2.4 Points
Introduction To place an object in a model you may need to pick points. To place an object where no lines or objects intersect, you have the following options to place objects:

•     Use snapping commands.

•     Use construction planes, lines and circles

•     Create points.

There are many ways to create points in Tekla Structures. Which method is the most convenient at each time, depends on what you have already created in the model and which locations you can easily pick.

When you create points, Tekla Structures always places them according to the work plane coordinate system. Points located in the view plane are yellow and points outside the view plane are red.

Point properties
To view the properties of a point, double-click the point or click Tools > Inquire > Object and select the point.

Phase and ID              Just like any other object, each point has an ID number which is used in log files. Points and

parts have phase numbers. You can filter objects by their phase and ID numbers.

Coordinates               The point information you are most probably interested in is the local (work plane) and global

x, y, and z coordinates of a point. Checking them convinces you of the correct location of the point or some other object related to it.

Creating points

To create points, use the icons on the Points toolbar, or select a command from Modeling > Add Points. The following table lists the commands for creating points and gives a short description of each one:

Command Icon Description
Along Extension of Two Points Creates points as an extension of a line between two picked points.
Parallel to Two Points


Creates two offset points, parallel to a line, between two picked points. This command also creates construction lines showing offset distances.
On Line


Creates points which divide a line.
Command Icon Description
On Plane… Displays the Point Array dialog box and creates a point array relative to the current work plane.
Projected Points on Line Projects a picked point onto a picked line.
Using Center and Arc Points V. Creates points along an arc.
Using Three Arc Points Creates points as an extension of an arc defined by three picked points.
Tangent to Circle Creates a point where a circle and a line meet tangentially.
