Create pop-marks in NC files

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 partmain part that exists in an assembly

The assembly main part in a steel assembly may have other parts welded or bolted to it. By default, the assembly main part is not welded or bolted to any other parts.

The user can change the assembly main part.

. Pop-marks are usually made using a drilling machine that drills a small holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

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 modelmodel that is active in Tekla Structures

The current model can be a single-user model, a shared model or a working model.

folder.

Note:

Pop-marking affects numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

. 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.

  1. On the File menu, click Export > NC files .
  2. 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.
  3. Click the Pop-marks button.
  4. In the Pop-Mark Settings , click Add to add a new row.
  5. 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:

    Option Description
    Main part profile type Select the main part profile type that is pop-marked. The list contains profiles according to the DSTV standard.
    Main part name Enter the names of the main part profiles. You can enter several part names separated by commas, for example, COLUMN, BEAM.

    You can use wildcards (* ? [ ] ). For example, HE* matches all parts with a profile name that begins with the characters "HE".

    Part name can contain more names separated by comma.

    Sec part profile type Select the secondary part profile type.
    Secondary part name Enter the names of the secondary part profiles. You can enter several part names separated by commas.

    You can use wildcards (* ? [ ] ).

    Part name can contain more names separated by comma

    Pop-mark location Select how the secondary part is projected onto the main part.
    • Left side : The left side of the secondary part is marked on the main part. The left side is the side of the secondary part that is closest to the start point of the main part.

    • Right side : The right side of the secondary part is marked on the main part.

    • Both sides : Combines Left side and Right side.

    • Center : Center of the secondary part.

    • Left side holes : Marks the main part with the position of holes in the secondary part, on the left side of the secondary part.

    • Right side holes : Marks the main part with the position of holes in the secondary part, on the right side of the secondary part.

    • Both side holes : Combines Left side holes and Right side holes.

    • Middle line : Marks two points on the middle line of the secondary part x axis.

    Move to flange Select to which part of the main part flange the pop-marks are moved. The options are None , Both flanges , Top flange , and Bottom flange.
    Edge distance Enter the minimum distance from a pop-mark to the edge of the main part. Tekla Structures does not create pop-marks inside this distance.

    If a pop-mark is inside the defined edge distance, Tekla Structures moves it, unless you have set Pop-mark location to Center.

    Secondary pop-marks Select whether pop-marks are created to the secondary parts.

    Then define the pop-mark settings on the Pop-marking options tab:

    Option Description
    Rotate part if pop-marks or other items only on the back First select the Pop-marks on the back check box and then one of the options.

    Also set the Hole diameter.

    Rotate part and drill through pop-marks on the back if items or more pop-marks only on the back
    Drill through pop-marks on the back if no other items on the back
    No pop-marks on overlapping holes Select if you do not want to have pop-marks on overlapping holes.
    Add pop-marks to centers of studs Select to have pop-marks in the stud centers.
    Show pop-marks in the model Select to show pop-marks in the model.
    Consider zero diameter holes as pop-marks Write zero diameter bolt holes as a pop-marks.
  6. Click OK.
  7. Select the parts in the model.
  8. Create NC files.

Pop-marks are written in the BO block in the DSTV file as 0 mm diameter holes.

If needed, pop-marks can also be displayed in drawings. In drawings, select the on/off check box in the part properties to display the pop-marks.

Tekla Structures displays thick red lines for each pop-mark pair in the model viewview that is represented in the modeling mode

Model view is available also in the drawing mode and it is represented in its own window.

Examples

Tekla Structures marks the center point of all round secondary profiles on a main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

(1) Main part can be an assembly main part or a cast unit main part.

(2) input part that the user selects first when creating a component

(2) Connections and details always have a component 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.
