Tekla Structures produces NC files in DSTV format. You can select the information to be included in NC files and NC file headers, and define the desired pop-mark and contour mark settings. You can also produce MIS (Manufacturing Information System) list files according to the DSTV standard.

NC (Numerical Control) refers to a method where machine tool operations are controlled with a computer. The NC data controls the motion of CNC (computer numerical control) machine tools. During the manufacturing process a machine tool or machining center drills, cuts, punches or shapes the piece of material.

After you have finished detailing a Tekla Structures model, you can export the NC data as NC files from Tekla Structures to be used by CNC machine tools. Tekla Structures transforms the part length, hole positions, bevels, notches, and cuts into sets of coordinates that the machine tools can use to create the part in a shop. In addition to the CNC machine tools, the NC files can also be used by MIS and ERP software solutions.

The data for the NC files comes from the Tekla Structures model. We recommend that you complete the detailing and create drawings before producing the NC files.

Tekla Structures produces NC files in the DSTV format (Deutscher Stahlbau-Verband) in the current model folder. In most cases, each part has its own NC file. You can also produce NC files in the DXF format by converting DSTV files to DXF files.

DSTV is a standard interface for geometrical description of steel structure pieces for the post-processors with numerical control. The essential aim of this interface is to be neutral, which means that with only one standard description you can manage several different NC machines. The interface standardizes the link between a CAD-program or a graphical system via a CAM file for the NC machines. The geometry of the piece is introduced completely neutrally, and after knowing the parameters of the NC machine, the post-processor is able to translate this neutral language to the NC machine language. For more information, visit https://dstv.deutscherstahlbau.de/ .

Notes and limitations:

Duplicate bolts on a part (bolts in the same location as another bolt) are by default ignored in DSTV NC export. The tolerated distance for bolts to be considered duplicates can be adjusted with the XS_BOLT_DUPLICATE_TOLERANCE advanced option.

The DSTV standard does not support curved beams, and therefore Tekla Structures does not create NC files for curved beams. Use polybeams instead of curved beams.

Contour mark and pop-mark settings should be fixed before numbering and drawing creation, because both affect numbering. For more information, see the following support article: "How scribing affects DSTV and drawing workflow" .

Create NC files in DSTV format

DSTV format is an industrial standard defined by the German Steel Construction Association (Deutsche Stahlbau-Verband). A DSTV file is a text file in ASCII format. In most cases each part has its own DSTV file.

On the File menu, click Export > NC files . If you have some predefined settings that you want to use, select the settings from the settings file list at the top and click Load . In the NC files dialog box, select the check box in the Create column next to DSTV for plates and/or DSTV for profiles .
To modify the NC file settings, select an NC file settings row, and click Edit...
In the NC file settings dialog box, modify the settings on the Files and part selection , Holes and cuts , Hard stamp and Advanced options tabs. Click OK to save your NC file settings and to close the NC file settings dialog box.

Hard stamps can be created for both the main part and the secondary parts. By default, Tekla Structures creates hard stamps only for the main part. Set the advanced option XS_SECONDARY_PART_HARDSTAMP to TRUE to also create hard stamps for secondary parts.

You can select to create only DSTV files, MIS files, both, or DSTV files embedded in MIS files.

If you want to add new NC file settings, click Add... This will add a new row in the NC file settings list, and the NC file settings dialog box is displayed, where you can give the settings a new name.

You can enter a unique name for the settings using Save as . Tekla Structures saves the settings in the ..\attributes folder under the current model folder.

For more information about the NC file settings, see the "NC file settings" section below.
You can customize the order in which information is displayed in an NC file, and add additional information on individual parts in the NC file header. To select the information to be included in the NC file header, click Header... , modify the information, and click OK :
- In the NC File Header Information dialog box, include in the Selected elements list the header information options that you want, and arrange the options in the desired order by selecting the option and using the Move up and Move down buttons.

NC file settings

Files and part selection tab

File location

The default folder is \DSTV_Profiles or DSTV_Plates under the current model folder.

The MIS files are created under the current model folder.

You can define another destination folder for NC files in one of the following ways:

You can enter the folder path in the File location box. You can also browse for the path.
For example, enter C:\NC .
If you leave the field empty, the NC files will be created in the current model folder.
To create the NC file in a specific folder under the current model folder, enter .\<folder_name> .
For example, enter .\MyNCFiles .

You can use the model-specific advanced option XS_MIS_FILE_DIRECTORY to define the destination folder for the exported NC files. Go to the CNC category in the Advanced options dialog box, and enter the desired folder path for the advanced option XS_MIS_FILE_DIRECTORY . The NC files will be created in the specified folder under a folder that has the name of the current model.

For example, if you define C:\NC , and the name of the current model is MyModel , the NC files will be created in the folder C:\NC\MyModel .

Add a revision mark to the NC file name.

The file name then includes a number indicating the revision of the file, P176.nc1 becomes P176_1.nc1 , for example.

Create what

Select the type of files to create:

NC files creates only DSTV files.

Part list creates only a MIS list file ( .xsr ).

If you create an MIS list file, enter a name for the list in the Part list file name box. Also, you need to click the Browse... button next to the Part list file location box and browse for the location where you want to save the list .

NC files and part list creates both the DSTV files and an MIS list file.

Combined NC files and part list embeds DSTV files in an MIS list file ( .xsr ).

Maximum size

The options define the maximum length, width, and height of the parts the machine tool can handle. Larger parts are sent to other machines.

Profile type profiles that are set to Yes in the Profile type list can be handled by the machine tool. Profile types are named according to the DSTV standard.

I : I profiles

U : U and C profiles

L : L profiles

M : Rectangular tubes

R : Round bars and tubes

B : Plate profiles

CC : CC profiles

T : T profiles

SO : Z profiles and all the other types of profiles

By default, Tekla Structures unwraps round tubes as plate profiles and uses the plate profile type B in the NC file header data. To change this, use the advanced option XS_TUBE_UNWRAP_USE_PLATE_PROFILE_TYPE_IN_NC .

Maximum size of holes Maximum size of holes options define how large holes the machine tool is able to drill. The NC file is not created if a part contains larger holes or its material is thicker than the specified values. The hole size is connected to material thickness or plate thickness.

Each row contains the maximum hole diameter and the material thickness. Both conditions have to be met for the NC file to be created. For example, a row with the values 45 means that when the material thickness is 45 mm or smaller, and the hole diameter is 60 mm or smaller, the NC file is created. You can add as many rows as needed. following example shows how the Maximum size of holes can be defined. In this example, we have the following situation:

Three plates of different thickness.

Two bolt groups with equal sizes, and one bolt group with a larger size.

Maximum size of holes are defined as follows:

Test1 creates a folder under the model folder for the plates that meet the following criteria:

Hole diameter : 22

Plate thickness : 10

Test2 creates a folder under the model folder for the plates that meet the following criteria:

Hole diameter : 22

Plate thickness : 20

When you create NC files for the plates, the folder Test1 includes the plate PL350*10 and the folder Test2 includes the plate PL350*20 . The plate PL350*15 is not included in any folder, because the hole size criterion is not met.

The order in which you enter the criteria is important: enter the most exclusive criteria first. If you define the criteria in a different order, the results will also be different.

Holes and cuts tab


Setting	Description File format	DSTV is the only available value.

Inner corners shape

The Inner corners shape option defines the shape of, for example, web notches or flange cuts at the beam end.

The Inner corners shape option also affects cuts on the flange:

The Inner corners shape option does not apply to rectangular openings that are located in the middle of a part:

The Inner corners shape option does not apply to those inner contours that are already rounded in the model. The model values remain intact.

The examples in the below show how the different inner corner shape options affect the part in the NC file. The original part in the model has flanges cut entirely and the web is notched.

Option 0 : Radius

The inner corners are shaped like holes with a given radius. A separate BO block is not written to the NC file.

Option 1 : Tangential

The inner corner is rounded according to the value in the Radius box.

Option 2 : Square

The corner is as it is in the model.

Option 3 : Drilled hole

A drilled hole is added to the inner corner. The hole radius is the same as the value in the Radius box. Holes are written as a separate BO block to the NC file.

Option 4 : Tangential drilled hole

A drilled hole is added tangentially to the inner corner. The hole radius is the same as the value in the Radius box. Holes are written as a separate BO block to the NC file.

If the inner corner Radius is set to be too large, an NC file is not created to avoid manufacturing errors. The dstv_nc.log file in the model folder shows the error messages, and indicates the parts that have failed and the maximum allowed inner corner radius.

For the radius to be valid, the hole (including angles) must be equal to or greater than radius x 2. For example, a hole with angles needs to be even smaller than radius x 2, so that it would not hit the weld preparation area.

Distance from flange within which web is not cut

The Distance from flange within which web is not cut option defines the height of the flange clearance area. The clearance check only affects the I , U , C , and L DSTV profile types.

If a cut in a part is located closer to the flange than the clearance in the model, the cut points inside that clearance are moved to the border of the clearance area when the NC file is written.

The part how it is modeled. The cut goes closer to the top flange than the defined flange clearance in the NC file settings:

The part how it is written in the NC files. The dimension shows the clearance. The top of the original cut is moved so that the clearance area is left free. The bottom of the cut is not moved.

Machine slots as

The Machine slots as option defines how slotted holes are created:

Ignore slots : Slotted holes are not created in the NC file.

A single hole in the center of the slot : Drills a single hole in the center of the slotted hole.

Four small holes, one at each corner : Drills four smaller holes, one at each corner.

Internal contours : Flame-cuts the slots as internal contours.

Slots : Leaves slots as they are.

Maximum diameter for holes to be drilled

The Maximum diameter for holes to be drilled option defines the maximum hole diameter. Holes and slotted holes that are larger than the maximum hole diameter are manufactured as internal contours.

Maximum diameter for circular cuts to be drilled

Maximum diameter for circular cuts to be drilled defines the maximum circular part cuts. They are written as holes if the diameter of the cut is less than the value defined for the setting. Smaller internal circular cuts are converted to holes.

Hard stamp tab

Assembly position: A1.nc1 , A2.nc1

Assembly and part position: A1-P1.nc1 , A2-P2.nc1

The following example shows a hard stamp that contains the elements Phase , Part position , Material , and Text .

Hard stamp placing

If you set the option By orientation mark to Yes , the default face is changed from bottom ( u ) to top ( o ) for L profiles, rectangular tubes and round bars.

The Side option defines the side of the part on which the hard stamp is placed.

The Position along the part and Position in depth of part options define the position of hard stamps on parts.

These options move the hard stamp on the same face it is created, but they cannot move the stamp to a different face. If the face is, for example, the bottom flange, you can move the stamp to a different place on bottom flange, but not to the top flange.

Default faces for different profiles:

I profile: Bottom flange ( u )

U and C profiles: Back side of web ( h )

L profiles: Back (h) or Bottom ( u )

Below is an example, where the Change external contour (AK block) radius sign is not selected.

Below is an example, where the Change external contour (AK block) radius sign is selected.

Curve detection controls whether three points should be read as a curve instead of two straight lines. When Curve detection is set to Yes , Tekla Structures checks the edges of a solid against a virtual curve described by the edges to see if the edges are curved or straight based on the Chord tolerance value. Enter the Chord tolerance value in millimeters. Curve detection is on by default.

The image below describes the chord tolerance.

Select whether to convert I profiles to T profiles when a flange is missing. You can select either Yes or No .

Skip unnecessary points

Select whether to keep or skip the points that are almost collinear.

If the creation points of a contour plate differ less than 0.3 mm from a straight line, they are skipped in the NC file when this setting is selected. When the setting is not selected, every creation point of a plate is written to the NC file.

Skip unnecessary points not selected:

Skip unnecessary points selected:

Create KA block for

Select the following options to show bent line information for bent plates and polybeam plates in the NC file KA block: Unfolded bent plates and Unfolded polybeam plates .

Create pop-marks in NC files

Pop-marks are small holes that help the shop assemble individual parts to form an assembly. Tekla Structures is able to write the pop-mark information in NC files to help position parts that will be manually welded to the assembly main part. Pop-marks are usually made using a drilling machine that drills a small hole in the surface of the material.

Limitation: Tekla Structures pop-marking does not work with polybeams.

Tekla Structures only creates pop-marks for parts for which you have defined pop-mark settings. You can save the pop-mark settings in a .ncp file, which Tekla Structures saves by default in the ..\attributes folder under the current model folder.

Note:

Pop-marking affects numbering. For example, if two parts have different pop-marks, or one part has pop-marks and the other one does not, Tekla Structures gives the parts different numbers. In the NC files dialog box, select the parts for which you want to create the pop-marks by selecting the corresponding check boxes in the Pop-marks column. Click the Pop-marks... button. In the Pop-Mark Settings , click Add to add a new row. To define which parts are pop-marked and where the pop-marks are created, enter or select information for each item on a row.

The order of the rows in the Pop-Mark Settings dialog box is important. Enter the most limiting definition first, and the most generic one last.

First define the pop-mark settings on the Parts to pop-mark tab:

The default symbol for pop-marks is xsteel@0 . You can change the symbol with the advanced option XS_POP_MARK_SYMBOL .

Tekla Structures displays thick red lines for each pop-mark pair in the model view which was last updated.

Examples

Tekla Structures marks the center point of all round secondary profiles on a main part, and does not create pop-marks closer than 10 mm to the main part edge.

Tekla Structures projects the hole location in the secondary plates onto a main part.

Create contour marking in NC files

Tekla Structures is able to generate contour marking in NC files. This means that information on the layout and the parts that are welded together can be added to the NC files and passed on to the machine tool.

Limitation: Tekla Structures contour marking on polybeams does not work in all cases. The visual placement of contour marking on polybeams has been improved.

Tekla Structures only creates contour markings for parts for which you have defined contour marking settings. You can save the contour marking settings in a .ncs file, which Tekla Structures saves by default in the ..\attributes folder under the current model folder.

You can add contour marking to both the main and the secondary parts.

Note:

Contour marking affects numbering. For example, if two parts have different contour markings, or one part has contour markings and the other one does not, Tekla Structures gives the parts different numbers.

Edge distance	Define the minimum distance from a contour mark to the edge of the main part. Tekla Structures not create contour marks inside this distance. Click OK and create the NC files. Contour marking is written in the `PU` and `KO` blocks in the DSTV file. Tekla Structures displays contour marking as thin magenta lines in the model view. Fittings and line cuts in NC files When creating NC files in DSTV format, the method you use to cut the end of the beam affects the beam length in the NC file. Fittings affect the length of the beam in the NC file. Line cuts do not affect the length of the beam in the NC file. When you cut the beam end, use the fitting method to make sure that the beam length is correct in the NC file. The overall length of a beam will be the fitted net length of the beam. This means that Tekla Structures always takes the fitting into account when calculating the beam length. For lines, polygons, or part cuts, the cut does not affect beam length, but the overall length in the NC file will be the gross (initially modeled) length of the beam. If you want to use the shortest possible length in an NC file, use the advanced option XS_DSTV_NET_LENGTH . Net and gross length If you want to include both net and gross length into NC file header data, use the advanced option XS_DSTV_PRINT_NET_AND_GROSS_LENGTH . Create round tube NC files You can create NC files for tubular hollow sections. You first need to use specific tube components to create the connections. Create the following tube-to-tube and tube-to-plate connections: Tube-Chamfer Tube-CrossingSaddle Tube-MitreSaddle+Hole Tube-Saddle+Hole Tube-SlottedHole After using the components, you can create an NC file for data export. The tube NC file creation results in an XML file that contains the model data. Limitations: To get correct tube NC export results, note the following limitations: Line cuts and fittings created manually or by other components will be exported as simple chamfers. Part cuts are not supported in the XML export to HGG tube NC files. Holes created by bolts are not supported, and they will not be exported. Curved beams are not supported. For square or rectangular tubes, use File > Export > NC files to create DSTV files. On the File menu, click Export > Tube NC files . In the Create Tube NC Files dialog box, enter a name for the export file, and browse for the location where you want to save the file. By default, the file is saved in the model folder. Select whether you want to create the file for selected parts or for all parts. Click Create . Tekla Structures creates an XML file and a log file in the location you defined. Convert DSTV to DXF Use the DSTV to DXF converter to convert DSTV files to DXF format files to be used in fabrication production solutions, such as plate nesting or production management. Many production automation solutions, especially some plate nesting solutions, only support the import of DXF files, not DSTV NC files. The DSTV to DXF converter provides key layer and quantity information in the format expected by the production solutions. The converter also supports the automation of the conversion processes through the command prompt and macro templates, which allow you to set up and customize your automation routines. Convert using the DSTV to DXF Converter To open the DSTV to DXF Converter , in the side pane, click the Applications & components button, search for the DSTV to DXF Converter , and double-click the DSTV to DXF Converter button. The DSTV to DXF Converter dialog box is displayed. Define the desired settings on the various tabs, and use the Add button to add the .nc files. The settings are described in the "Conversion settings" section below. Click the Convert button. The DXF files are created in the specified folder: You can open the output folder by clicking the Open output folder button. To check the conversion log, click the Show log button. Convert DSTV to DXF using a converter template You can use a converter template to automate the conversion process. All you need to do is to fill in the necessary information in the template file in a text editor. Once you have it set up, you do not need open and load the settings in the DSTV to DXF Converter dialog box, and you can do the conversion just by double-clicking one button. In Applications & components , right-click the DSTV to DXF Converter Template button, click Edit , and select a suitable text editor. This opens the DSTVtoDXFConverterTemplate.cs template located in the ..\TeklaStructures\<version>\bin\<Env>\Common\macros\modeling folder. Scroll down to modify the strings to suit local environment and user preferences: `/** Modify these strings to suit local environment and user preferences. */` `private static string attributeFile = @"standard";` `private static string inputFolder = @"./DSTV_Profiles";` `private static string outputFolder = @"./NC_dxf";` `private static string files = @"PL.nc1, BPL.nc1, FLT.nc1";` `private static bool overwrite = true;` `standard` : attribute file name you want to use for conversion `./DSTV_Profiles` : input folder in which single and batch files are searched for `./NC_dxf` : output folder where to create the .dxf files `PL.nc1, BPL.nc1, FLT.nc1` : list of file names each enclosed in quotes or wild card `true` : option to overwrite or not the existing *.dxf files.
