Creating a Rebar Drawing

You can generate and customize the drawing of rebar layers with annotations.

The Rebar Drawing command, available in the Multi-Discipline Drafting app, provides a simplified representation of a rebar layer in a Generative Drawing document with the possibility to choose the bars in the layer that have to be projected. You can also automate the creation of an annotation on top of the 2D bar geometry.

This task shows you how to:

Before you begin:
  • Open/Create a product with at least one rebar layer.
  • The rebar annotations are defined in a catalog that is linked to the resource set in the Data Setup. You need to familiarize yourself with the sample files which are provided for you by default from win_b64\resources\Civil\Rebars\DrawingTemplate. The files include the View Update Rule Template.

Define an Annotation Template

Follow this procedure to add annotations on your rebar drawing using Data Setup. You can use a .3dxml template with the Catalog component type.

You can define your own template if you have the Multi-Discipline Drafting Template role.

Data Setup is an app that allows you to put together resources and share them with all the actors in the project within one or several collaborative workspaces.

  1. Create/Identify a resource file, for example Catalog.3dxml containing the annotations' rules template definition for the rebars in a catalog.

    It will be used as a Chapter resource type for the setting up procedure.

  2. To import the resource file, select Add > Import > 3D XML... and the .3dxml file.

    In the Import Option area of the dialog box, ensure that Import As Ref is selected. For full instructions, see 3DEXPERIENCENative Apps: Importing and Exporting: Importing 3D XML Files.

    The 3D XML resource file is imported into the database.
  3. Ask your Data Setup manager, or if you are granted the rights to use Data Setup (Owner role) or, associate the resources to a collaborative space and add extensions (Leader role), perform the procedure yourself:
    1. Assign the Chapter resource file to the View Update Rule Template in the related resource set table named ASD Drafting resources.
      The View Update Rule Template resource is displayed under the ASD Drafting resource set.
    2. Associate the resource set table, ASD Drafting resource, to a collaborative space.
    3. Click Share > Save > Save with Options to save your changes.
    4. Log out from the 3DEXPERIENCE.
    5. Log in again to benefit from the Data Setup modifications. All changes made through Data Setup will be shared with all actors working in the same collaborative space.
    Note: If no template is assigned in the resource, no annotation is created by the Rebar Drawing command, only 2D geometry appears in the drawing.

Create a Rebar Drawing

You can generate a drawing from the rebar layers' geometry.

  1. From the Building and Civil Assemblies app, open a product.


    Note: The 3DTag (for example on rebar layer 17) will be identical to the annotation text you may generate in the 2D representation of the rebar layer. For more information, see the last section.
  2. Select its Insert > Drawing contextual command and click ASD Drawing.
    The Multi-Discipline Drafting app opens.
  3. From the View Layout section of the action bar, select Front View and click a green plane in the 3D area of the root product for projection. Click the 3D area to create the view.
  4. From the Civil Engineering section of the action bar, click Rebar Drawing .

    All the layers are projected in this view and they are listed in the Elements tab of the Rebar Drawing dialog box. As bars are volumes, this is their layout that is projected into 2D.



    The dialog box displays the following information:

    • A combo box to select one or several layers and apply some preferences.
    • Name: the name of the rebar layer.
    • Group Prefix: name of the group of the bars. By default, the proposed representation of the selected layer is the Single Bar group. You can select another group representation. For information , see the steps further down.
    • Number: index of bars in the layer to be displayed.
    • Status: status color codes
      • : Numbering and annotations are created successfully.
      • : Drawing view is not up-to-date. Click Apply to update it.
      • : Numbering is not launched or failed because the annotation template is not set/found. If the template is changed, all the annotations created with the previous template are deleted. To retrieve it, right-click Choose Template on the No Template cell.
    • Locked: the button is checked when the value is entered manually in the Number column. And automatic numbering does not change this value.

Change a 2D Layer Rebar Representation

You can configure different bar representations in the 2D view.

  1. Select the Groups tab.
    The dialog box contains a series of commands dedicated to the group management of the bars, as detailed further down. The bar group types are detailed in the list with the following columns:
    • Prefix: name of the group.
    • Definition: bar indexes from 1 to N. N stands for the last bar index of the rebar layer. The * symbol stands for all the bars.
    • Template: the name of the template, when an Annotation Rule Template has been defined.
    Notes:
    • A template is assigned to each group defined by default and, its name starts with Single Bars Template or First and last bars Template or All bars Template.
    • If the template is replaced, all the annotations created with the previous template are deleted. For more information, see the status color codes in the previous section.
  2. To automatically define the bar(s) that must be displayed in the drawing, select a rebar layer in the list under the Elements tab.
  3. Click the Move selected Element(s) to a Group command and select a group in the list.
    • If Single bars is selected: the index of the bar at the middle of the layer is proposed. The related definition is N/2.
    • If First and last selected: the index of the first and last bars are proposed. The definition for this group is then set to 1, N.
    • If All bars selected: All the bar indexes are proposed. The definition symbol for this group is *.
  4. Optional: Enter manually the index of the bars in the Number column:
      • Single number, for example: 3 to display only the 3rd bar of the layer.
      • Several numbers separated by a comma, for example: 3,8 to display both 3rd and 8th bar of the layer.
      • * to display all the bars of the Layer.
      • N to display the last bar of the Layer, for example: 1,N displays first and last bar of the Layer.
    Note: If a value is entered manually in the Number column, the value is locked (Lock column) so that the automatic numbering does not change this value.
  5. To refresh the Drawing view, take the numbering changes into account and display the annotations, click Apply.

    In the Groups tab, the three groups are available: Single bars, First and last and All bars. They cannot be modified nor deleted. Each cell in the list is read-only.

  6. To define your own group, click Create new group and do the following:
    1. A new line appears in the dialog box corresponding to the new group. Modify its properties if needed: the Prefix (D by default), the Definition (1 by default) and, the Template (with the No Template defined information in the cell).
    2. Right-click No Template defined and select Choose Template. The Catalog Browser window opens.
    3. Select the Unique Bar Template. This template also belongs to the Catalog resource file. The cell information changes from No Template defined into Unique bar Template.
    4. Click the Elements tab and to select the D group (user-defined group) in the list.
  7. To reset the indexes of the bars that have been selected in the list, click .
  8. To clear the indexes of the bars that have been selected in the list, click
  9. To remove the layers that have been selected in the list, click . If removed, the layers keep their default representation as volumes, no longer as wires, and no annotations are created for them.
  10. To move selected layers from one group to another, click and select another group in the list.
  11. Click Apply.

    You obtain the 2D representation of the bars that are displayed as wires in the drawing.

    If you select , only one bar is displayed by default for each layer selected in the list. Small black disks symbolize the bends' location.

    As explained in the first section above, an annotation rule template can be created to define your rebar annotations. Annotations appear along rebar drawings.

    The bars to be displayed can be modified and the annotation is changed accordingly by clicking Apply.

    Depending on the selected group, you obtain a different 2D representation:

    Single bars First and last bars All bars User-defined Group
    The representation displays only the middle bar of the layer. The intersection is symbolized by a circle and, an annotation text is connected to the bar. A segment represents the width of the rebar layer. Small black disks stand for the bendings. The representation displays only the first and last bars of the layer and, a double leader annotation is created. All the bars are projected into the drawing. With this symbol , you can visualize the intersections. As defined by default, representation displays only the first bar with its annotation.
    Notes:
    • The annotation indicates the number of bars in the layer (for example: 17), the spacing between the bars (for example: 0.04m) and, the bar mark number when it exists.
    • The text of the annotation is the text of the 3DTag defined in the 3D design. If you customize the 3DTag, the 2D annotation is synchronized with the same text.
  12. To manipulate the annotations in the 3D area, click OK and do the following:
    1. Select the annotation text.
    2. Move the double-headed arrow manipulator under the annotation.
