1 Tekla Structures 18.0 SR1 Release

Notes

This document explains new features, fixes and improvements in Tekla Structures 18.0 ServiceRelease 1. We recommend this service release for all Tekla Structures 18.0 users.

General

Zero inches in dialog boxes

Zero inches 0" are now shown even if the XS_DISPLAY_ZERO_INCHES advanced option isnot set.

TT75418


6/18


Modeling

User-defined attributes for bolts and welds

Previously, the user-defined attributes of bolts and welds had some incorrect default values inthe list box options. This has now been fixed.

TT74949

Loading applied values from user-defined attributes standard file Loading applied values from user-defined attributes standard (.more ) files did not work

correctly if a dialog box was open. For example, if the column property dialog box was open, thestandard.clm.more file was not applied correctly when model was created or opened.

TT75128

Surface treatment

Adding surface treatment to complex planes has been improved.

TT71132

Snapping

It is now again possible to snap to the distant reference points of a part.

TT74220

Model Organizer

When defining the properties that are shown in the object pane, you can now define that bothreference object properties and report properties are shown under a certain property. Use asemi-colon to separate the properties.

TT75890

Reinforcement

Reinforcing Bar Shape Catalog

You can now apply the reinforcing bars created with the Reinforcing Bar Shape Catalog intomultiple concrete parts at the same time. Previously, the reinforcing bars could only be appliedinside one concrete part at a time.

See below for an example before the fix: Reinforcing bars are applied to one part at a time.


7/18


See below for two examples after the fix: Reinforcing bars applied into multiple parts at a time.


8/18


TT74912

Reinforcement adaptivity

In 18.0 (and newer versions) the adaptivity sometimes failed when you changed the geometryof complex profiles. This has now been fixed.

TT77070

Analysis and design

Analysis models

Analysis models are now saved when you save the model with Save As.

TT76619

Deleting analysis parts

Previously, deleting a large number of analysis parts from an analysis model was slow. This has

now been fixed. Deleting is now faster also when a large number of model parts are deletedwhile the analysis model is active and also analysis parts have been selected.

TT76597

Drawings

Work plane and updating drawings

In Tekla Structures 18.0 final, if you set the work plane to any other coordinate than the model's0 coordinate when creating or editing drawings, your drawings would update incorrectly. Thishas now been fixed.

TT76527


9/18


Section view boundary

The section view boundary of the selected section view was not always highlighted in theparent view. This has now been fixed.

TT75069

Rotating drawing views

Rotating a drawing view no longer moves the view far away from its original position.

TT75142

Showing grids

Grids were not show in a view that had a negative depth. The view plane was not inside theview. This has now been fixed.

TT74460

Updates in associative notes

If an associative note was edited using the Mini Toolbar, the note was not updated after achange in the model. This has now been fixed.

TT75256

Removing unnecessary drawing files

A new command Remove unnecessary drawing files was added in the Customize dialog boxunder the Drawings category. You can use this command for removing drawing files in thesingle user mode.

You need to have full privileges for using this command. The following line needs to be addedin the privileges.inp file:

action:RemoveUnnecessaryDrawingFiles [who] [access]

[who] is everyone or Windows logon name, or domain name

[access] can be none/view/full. In this case, set it to full.

When you use this command, ensure that nobody else is using the model at the same time.

TT74707

Panning in drawing mode

Performance improvement in panning in drawing mode caused quite often a checkerboardeffect. Now the checkerboard is visible only when the graphics are too heavy to be fullyrendered on panning.

TT76676

Part marks

Sometimes an application error occurred when part marks were updated. This has now beenfixed.

TT76340

Drawing filters

Drawing filters were not working correctly, as previous filter rules where used even though thefiltering dialog box contained no filter rules. This has now been fixed, and previous filter rulesare not used anymore.

TT73733


10/18


Recreating drawings

Now selecting No in the drawing recreation confirmation box works correctly, and the selecteddrawings are not recreated.

TT74397

Slotted holes

Slotted holes are now shown correctly in the drawings, and the bolt marks contain slot

information. In some older versions, slotted holes were shown as round holes, and bolt marksdid not contain any slot information.

A slotted hole in a model.

In the following example, only round holes are visible.

In the following example, the slotted holes are shown correctly.

TT48909


11/18


Showing bolt groups

In drawings, if bolts are drawn as symbols, Tekla Structures now shows only those bolts that areinside the view restriction box. In older versions, the bolts in a bolt group were not showncorrectly.

TT68823

Dragging in drawings

Sometimes dragging in drawings worked incorrectly and the whole drawing was moved. Thishas now been fixed.

TT75004

When you dragged the view plane, the view was in some cases drawn in an incorrect place onthe sheet. The view was drawn correctly if you saved and closed the drawing and opened itagain. This has now been fixed.

TT75975

Object level settings

Object level setting for parts are now working also in the enlarged views of the anchor bolt plandrawings.

TT75012

Minimum cut part length

The Minimum cut part length setting (View Properties > Shortening) was calculatedincorrectly in drawing cloning or update if there was a detail mark at the end of the view.

TT76476

Alignment tools

The alignment tools on the Alignment toolbar were not working. This has now been fixed.

TT74433


12/18


Multidrawings

Sometimes view placing was incorrect in a multidrawing if the selected drawings were split inseveral multidrawings.

TT67165

If you had an assembly drawing in a multidrawing, and you used multinumbering, the assemblydrawing views were placed incorrectly after update. This has now been fixed.

TT76620

Multidrawings with layouts are now placed correctly, and the size of the included drawing iscorrect (the same as that of the original drawing).

TT76625

View update in multidrawings has been improved, and views no longer move away from thecontainer box.

TT76931

"Use columns" template setting in cast unit drawings

An application error occurred when you updated a cast unit drawing containing reinforcement,and had selected the Use columns check box in the drawing template Row Properties. This has

now been fixed, and the Use columns setting works correctly.

TT76564

Rebar mesh view creator

The RebarMeshViewCreator macro did not draw the mesh view in correct projection if themesh plane was not parallel to the main view coordinate system. This has now been fixed.

TT74749

New template attribute for reinforcing bar groups: NUMBER_VISIBLE

There is now a new context-specific template attribute NUMBER_VISIBLE for reinforcing bar

groups. When added in a mark, it gives the number of visible reinforcing bars in a view.TT67347

Reinforcing bar group dimension plugin

The RebarGroupDimensionPlugin application is again available for use. This application offersyou altogether three dimensioning representations instead of one. It also allows you to adjustthe placing of the various elements in the dimension annotation more flexibly.

To use this application, add the RebarGroupDimensionPlugin command to a toolbar or to theUser menu through Tools > Customize in the modeling mode.

TT76258

TheRebar group dimension plugin

dialog box now contains a new option for showing orhiding the position text.


13/18


TT74383

Adjusting reinforcing bar location

The Adjust location command did not draw the reinforcing bar in the picked location if the firstor last reinforcing bar in the reinforcing bar group was outside view boundary. This has nowbeen fixed.

TT74408

The Adjust location command now works correctly also with tapered reinforcing bar groups.TT67062

Sometimes extra dimension lines were drawn when you had selected the Adjust locationcommand for a reinforcing bar.

TT74264

Reinforcing bar marks

Reinforcing bar marks were not created if the reinforcing bar was placed at a customizedlocation (Reinforcing Properties > Visibility of reinforcing bars in group > Customized), or ifthe Adjust Location command was used.

TT74263

Actual or nominal reinforcing bar size

In the drawing mode, the reinforcing bar diameter is now displayed in the same way as in themodeling mode. By default the diameter is "actual". If the advanced optionXS_USE_ONLY_NOMINAL_REBAR_DIAMETER is set to TRUE in the Advanced Options categoryConcrete Detailing, the diameter is "nominal".

TT75599

Circular reinforcing bar group hooks

Circular reinforcing bar group hooks were not created correctly in drawings. This has now been

fixed.TT73244

Tapered reinforcing bar group dimension direction

Reinforcing bar dimension line, dimension mark and tagged dimension mark are now created inthe reinforcing bar group direction, not at an angle even if the group is tapered.

TT67642

Reinforcing bar end symbols

Representation of reinforcing bars that point away from the drawing is now changeable. Youcan customize reinforcing bar end symbols (cross, circle, filled circle) in a symbol file by editingthe symbol file bent.sym, which in the default environment is located in..\ProgramData\Tekla

Structures\\environments\common\symbols . Or, you can create a newsymbol file in the same folder, for example,my_new_symbols.sym, and take it into use in therebar_config.inp by entering the following string:EndSymbolFile=my_new_symbols.sym

TT67680


14/18
