-
Open a 3D Shape.
-
From the Reinforcement section of the action bar,
click Rebar Group
.
-
To select the input rebar support, hover over a surface or an edge in the 3D area.
-
To get a predefined layer profile, click Rebar Template
in
the contextual toolbar and select an object type in the Search
Results list that opens.
The rebar type categories are:
- A fixed rebar type, when the rebar shape you envision is defined by a fixed
dimension value. For example, each rebar layer has the same size, shape, and number
of bends.
- An adaptive rebar type limited by planes when the rebar follows the shape of the
geometry such as surfaces until limiting planes.
- An adaptive rebar type when the shape follows surfaces until its boundaries.
-
Click OK to validate your choice and go back to the Concrete Structures 3D Design
app.
The Rebar Group dialog box appears, displaying the following
commands:

Profile, you can choose a configuration value.

Layer Properties |
Expandable section to display:
- The preview of the rebar template:

- Its name and status
- The commands to export or copy it
- The editable pattern configuration
|
Distribution |
Expandable section to verify or edit the pattern information and use
commands to delete , edit or select
another pattern (only
possible after the deletion of the existing one). For more information, see
the step below. |
 |
Deletes a rebar layer. |
Name |
The name of the rebar layers created from a sketch or a template. Select
a line to highlight the rebar layer in the 3D area. A Shift Options command appears in a contextual
toolbar, pointing to the layer, and you can hide or show the shift label by
clicking in the
Rebar Group dialog box. For more information, see
further below. |
Type |
On the same support, you can create several rebar layers with the
Sketch or Template mode. The
Type column of the panel with the
Sketch
or
Template
icon indicates
the creation mode. |
Configuration |
Displays the diameter for the rebar layer. You can select another one in
the list. |
 |
To modify the rebar layer within the Rebar
Creation command. |
Each profile is used as a layer for a rebar group.

To reinitialize the rebar group distribution, expand the
Distribution section and do the following:
The Distribution area containing pattern information and,
commands to delete , edit or
select another pattern (only possible after
the deletion of the existing one).
The linear pattern is chosen by default and it is defined in the
Distribution text box. For example, if you enter
10x300mm , the pattern will contain 10 axis systems spaced by 300mm.
The distribution text is converted into pattern definition.
The unit is set in Preferences: From the top bar, select , and then click the Common
Preferences tab and expand the section.
You can choose the Count or Spacing modes and, the active mode is indicated in the
dialog box. For more information, see next step.
A list of a minimum of three rebars containing the pattern is displayed. Click to expand the list.
- Edit the text in the Distribution box, for example:
300mm+2x400mm+335mm , or 3x300 . The pattern contains
one axis system at 300mm, two axis systems every 400mm, and one more axis system at
335mm.With the textual distribution, it is no longer required to edit the Pattern
feature to modify or create Pattern Groups and their distribution. The general
distribution text format is: C1 x S1 + C2 x S2 + C3 x S3. "Ci": is the number of
axes of the group "i". If the number of axes of this group is equal to 1, it can be
omitted. "Si": is the spacing length of this same group. It can be associated
with a unit, or without any unit. If it does not have any unit, the unit set in
Preferences is used. If a unit is used to define a length, use the same unit for all
lengths.
- Create Pattern groups: Create or select points in the 3D area to
split existing groups into two parts.
- When you initialize the rebar layer layout, there is only one group in the
pattern. The Count and Spacing modes can be changed with the combo box. If you click:
- Count
: Only count
value modification and only one group are allowed.
- Spacing
: Only spacing
value modification and only one group are allowed.
- Count and Spacing
: Count
and Spacing values modification is allowed and several groups can be created. If a
Pattern end point is specified, a Limit Spacing option is
available to shift the Pattern distribution.
If the current mode is Count and spacing, it can contain as many groups as
required, separated by the plus sign. All the groups created are in the Count and
spacing mode. There cannot be several groups with different modes. If you change the
definition of one group, the text editor is grayed out. If a pattern end point is
specified, a Limit Spacing option is available to shift the
pattern distribution. If start and end offset values are defined, distribution
is done between these boundaries. The start and end offsets are not managed in the
text editor. Edit the pattern by clicking to modify their
values.
- Click
to start the pattern
for more precise edition.
Click anywhere in the 3D area to
validate the distribution text, and the preview of the Axis systems is refreshed. An
error message may appear if the input distribution text is incorrect. The pattern
distribution is reinitialized with this text. Then you can continue to edit the rebar
layers.
-
To edit or move a rebar layer, especially when it intersects with another one in the
3D area,
click it in the Rebar Group dialog box and do one of the
following:
-
Change the shift of the layer with the option called With
length by defining a numerical length value nmal to the template plane.
And click Reverse
to define the
shift side.
-
Change the shift with the From selection option, by using
another layer as contact referential. The From selection is
highlighted to reveal the possible selection of a layer to move the first one. Click
Reverse
to define the
shift side.
Before clicking Apply, you can visualize the first bar of each
layer in the 3D area.
-
Click Apply to compute the rebar layers.
 With
the plane colors, you obtain this: 
Each rebar layer is defined by an object type, the pattern, and the plane. In
the tree, the Reinforcing bars Group Set contains a Geometry node aggregating the geometries
of the rebar groups and the new template. Note:
If you use a curvilinear pattern,
the faces used to create the rebar layer are positioned arbitrarily (see Fig.1.) You
need to move the faces manually so that the layers follow the shape of the faces (see
Fig.2.)
