Settings in the Options dialog box
The Options dialog box (File menu > Settings > Options) contains the current values for a number of Tekla Structures settings.
Check the settings before you start modeling and change them, if necessary.
The model-specific settings in this dialog box are saved in the options_model.db and options_drawings.db databases in the model folder, and the user-specific settings in options.bin in your local <user> folder. Changing user- or model-specific options in the Options dialog box does not require Tekla Structures restart.
You can also save your own settings by using the Save button. Then the standard.opt file is saved in the \attributes folder under model folder. You might want to copy this file to your firm folder. When you create a model, the standard.opt is read from the firm folder.
The options in the Options dialog box are described below.
Clash check settings
NOTE: Settings on this page are model specific. Changing the settings does not require Tekla Structures restart.
Depending on how the objects selected for clash checking have been modeled, different clash check settings are used. For example, if you have modeled embeds as studs, steel parts, or reinforcing bars, respectively either bolt settings, part settings, or reinforcement settings are relevant.
Tekla Structures uses a hard-coded tolerance when checking clashes between native parts. If native parts overlap less than 0.25 mm, clashes are not reported.
Option |
Description |
---|---|
Allowed penetration volume
|
Defines the allowed clash check tolerance if small collisions are acceptable and can be ignored. If the clashing volume is smaller than the given value, for example 1 mm3, then the clash is not reported. Enter the value in the current volume units. |
Clash check between bolt and bolted part |
Defines whether the model is checked for clashes that occur between bolts and the related bolted parts. If you select Yes, Tekla Structures will check the bolts against the real geometry of the bolted part profiles including roundings, and using the real bolt dimensions. |
Define the clash check clearance area for bolts
|
Use to check if bolts collide with parts and if there is enough space to fix the bolts. Enter the clearance dimensions in relation to the bolt head or nut diameter d (the larger value), and the nut thickness t. The clearance in front of the bolted parts is the same as the bolt length. If you do not enter a value, Tekla Structures uses the default value. If you clear the check boxes, the clearance will be zero. If Tekla Structures cannot find the bolt head or nut diameter in the bolt catalog, it uses the shank diameter instead. |
Exact solid weld clash check |
Defines whether the model is checked for duplicate and overlapping welds and for clashes that occur between welds and other objects (such as parts and bolts). If you select Yes, Tekla Structures will check the welds against other welds, against bolts, and against the real geometry of the part profiles including roundings, and using the weld solid dimensions with normal accuracy. |
Reinforcing bar vs steel part clearance (negative value to allow overlap) |
Defines the minimum clearance or the allowed overlap for reinforcing bars when they are checked against steel parts. To allow reinforcing bars to overlap steel parts and to ignore the ribs of bars, enter a negative value. The maximum overlap is the actual bar radius. Tekla Structures only checks the distance from bar side to part. Tekla Structures does not check the distance from bar end to part. If you clear the check box, Tekla Structures will not check the clearance. |
Reinforcing bar clearance (negative value to allow overlap)
|
Defines the minimum clearance or the allowed overlap for reinforcing bars when they are checked against other reinforcing bars. To allow reinforcing bars to overlap, enter a negative value. If you clear the check box, Tekla Structures will not check the clearance. |
Reinforcing bar cover thickness
|
Defines the reinforcing bar cover thickness. Tekla Structures checks the cover thickness against the part that the reinforcing bar belongs to. Tekla Structures only checks the distance from bar side to part surface. Tekla Structures does not check the distance from bar end to part surface. If the bar penetrates a part surface, a clash is reported, even if the bar is completely inside a cast unit or pour. If you clear the check box, Tekla Structures will not check the cover thickness. |
Components settings
Tekla Structures uses the information about the Components tab when it creates parts using system components.
Component properties defined in component dialog boxes override these settings. Tekla Structures only uses these settings if the corresponding boxes in the component dialog boxes are empty.
If you change settings here, Tekla Structures only applies the new settings to components you subsequently create. Components you created prior to changing the preferences are not affected.
NOTE: Settings on this page are model specific. Changing the settings does not require Tekla Structures restart.
Option |
Description |
---|---|
Profile names |
Defines parametric profile prefixes for plates. It is important that profile names are set up correctly so that you can use filters and wizards effectively. Profile names must exist in the profile catalog. If you want to use a parametric profile that does not have a name in the catalog, first add it to the Profile Catalog, then enter it here. Tekla Structures uses the Folded plate prefix when you use the folded plates in components. |
Bolts |
In components, Tekla Structures uses Factor of bolt edge distance and Compare edge distance to to check that the bolts it creates are not too close to the edge of a part, and warns you if they are. Check that Factor of bolt edge distance is set according to the standard you are using. The default edge distance setting depends on your environment. Compare edge distance defines whether the edge distance checks are based on bolt or hole diameter. To define the default bolt properties to use in connections, select a Bolt standard and Bolt size. |
Parts |
Part material defines the default part material grade. Part start numbers defines start numbers for parts that are Welded to primary and Welded to secondary, Loose parts, and Assembly loose parts. Cross-check these settings against the numbering series you define to make sure they do not overlap. If they overlap, Tekla Structures might create two non-identical parts with the same part number. This generates an error in the Numbering history log file. |
Drawing dimensions settings
NOTE: Settings on this page are model specific. Changing the settings does not require Tekla Structures restart.
For more information about dimension settings, see Define dimensioning.
Option |
Description |
---|---|
Exaggeration |
This setting defines the default values for Exaggeration limit and Exaggeration scaling. When you enable the exaggeration of the dimensions, a drawing dimension that is narrower than the defined limit is expanded. Exaggeration limit defines the default value for this limit. Exaggeration scaling defines whether you are using Paper or Model as the exaggeration scaling method:
For more information about exaggerated dimensions, see Create exaggerated dimensions. |
Absolute dimensions |
shows zero at the zero points in absolute dimensions. shows dimensions parallel to dimension lines in absolute dimensions. For more information, see Change the appearance of absolute dimensions. |
Dimensions in tags |
Units, Format and Precision define the default unit, format and precision used in dimension tags. Available units: mm, cm, m, foot - inch, cm / m, inch, feet. Available formats: ###, ###[.#], ###.#, ###[.##], ###.##, ###[.###], ###.###, ### #/# and ###/##.###. Available precision: 0.00, 0.50, 0.33, 0.25, 1/8, 1/16, 1/32, 1/10, 1/100, 1/1000 |
Show dimension in middle tag of automatic dimension |
Defines whether you want to create dual dimension tags in assembly, single-part, cast unit, or general arrangement drawings. For more information about automatic dual dimensions, see Add automatic dual dimensions. For more information about manual dual dimensions, see Add dual dimensions manually. When Tekla Structures creates the drawing, it adds the lower dimension tag in the selected unit, format and precision. |
Dimension line |
Dimension line extension length for line arrow defines the length of the line extension for dimensions that have line arrows. Note that line extensions are not applied to dimensions that have different arrows from line arrows, and certain knock-off dimension types. |

Option |
Description |
---|---|
Edge chamfer |
Line color defines the default line color of the edge chamfers in drawings. Line type defines the default line type of the edge chamfers in drawings. These values are overridden by the values set in the Edge Chamfer Properties dialog box. For more information about edge chamfers, see Edge chamfers in drawings. |
General settings
On this page, Autosave settings are user specific. All other settings are model specific. Changing the settings does not require you to restart Tekla Structures.
Option |
Description |
---|---|
Autosave |
Autosave interval: Autosave after every xx minutes defines the number of minutes after which Tekla Structures automatically saves the model. Note:
The time-based autosave interval does not apply to drawings. Autosave after creating every xx drawings defines the number of drawings after which Tekla Structures automatically saves your work. For more information, see: |
Default adaptivity |
Off means that adaptivity is not defined. Relative defines that handles retain their relative distances to the nearest part faces in relation to the part’s overall size. Fixed defines that handles retain their absolute distances to the nearest part faces. You can also modify the adaptivity settings for each part separately. These modifications override the default settings in the Options dialog box. For more information about adaptivity, see Modify the adaptivity of reinforcement, surface treatment, or edge chamfers in parts. |
Load modeling settings
Use the settings on the Arrow length tab to scale loads in model views.
Use the settings on the other tabs of this page to define the building code and safety factors Tekla Structures uses in load combination.
NOTES:
- Settings on this page are model specific. Changing the settings does not require Tekla Structures restart.
- You should not need to change the building code or safety factors during the project. If you change these settings, you will also need to change the load group types and check the load combinations.
Numbering settings

North direction |
Project north (degrees counter clockwise from global x) defines which direction is north in the model. Enter the value in degrees counter-clockwise from the global x axis.
|
Part viewing direction |
Defines which direction parts are viewed from in drawings. |
Beam skew limit Column skew limit |
Tekla Structures uses limit angles to determine whether a part is a beam or a column when creating orientation marks. Tekla Structures treats parts outside these limits as braces.
Parts skewed more than 80° are columns. Parts skewed less than 10° are beams. |
Preferred location for mark |
Defines the location of part marks in drawings, to the left or right end of the part. |
Mark always to center of column |
This setting only affects columns. Yes places part marks in the center of columns in plan views. To indicate part orientation, include compass direction (Face direction) in the part mark instead. No places part marks on the same flange in general arrangement and assembly drawings. |
Rebar set settings
NOTE: Settings on this page are model specific and only apply to rebar sets, not to single reinforcing bars, reinforcing bar groups, or reinforcement meshes. Changing the settings does not require Tekla Structures restart, but you need to update the existing rebar sets in the model. To do this, go to the Rebar tab on the ribbon and click .
Option |
