To define the length, select some other value than Default in End conditions right.

Shape of pin bars

Description

1

Select the shape of the pin bars.

2

Define the vertical dimensions.

3

Select if both bars 1 and 2 are created, or only one of them.

Pin bar direction for bevel edges

Select the direction of pin bars for bevel edges.

Dimensions

Define the pin bar dimensions.

Pin bar direction

Select the pin direction. This setting depends on the selected pin bar shape.

Pin spacing tab

Use the Pin spacing tab to define the pin bar creation and distribution along the concrete part.

Pin zones

You can define six zones for the pin bar distribution. For each zone, you can define the number of pin bars.

Description

1

Set the pin bar offset from the sides.

2

Define which pin bars are created.

The bars illustrated as dots are not created.

Pin bar zone settings

Option Description

Number of spaces

Define how many spacings are created for the zone.

Space

Define the spacing value for the zone.

Length

Define the length of the zone. Length is used if Number of spaces is left empty.

Horizontal space

Define the horizontal spacing of pin bars.

This setting is available if you have set Different spacing horizontal and vertical to Yes.

Vertical space

Define the vertical spacing of pin bars.

This setting is available if you have set Different spacing horizontal and vertical to Yes.

Pin bar distribution range

Select the pin bar distribution range in relation to the input points.

Cover thickness

Description

1

Define the minimum cover thickness for holes and notches.

Spacing for recesses

Description

1

Pin spacing value between the pins. This value is used to create the spaces when the length of the recess is between the defined values (2 and 3 in the image). Otherwise, the spaces are created using the Space value defined for the Zone.

2

Minimum length of the recess

3

Maximum length of the recess

Creation settings

Option Description

Creation method

Select how the spacing of pin bars is defined.

  • By exact spacings creates fixed spacing between each pin bar.

  • By exact spacing value with flexible first and last space creates fixed, regular spaces between the bars. Both the first and last spaces adjust to even out bar distribution.

Different spacing for horizontal and vertical

Select whether to reinforce multiple edges of a wall without changing the settings.

Consider openings

Select whether openings are taken into account and how the bar groups are created.

Edge bars tab

Use the Edge bars tab to define the edge bar dimensions and properties.

Edge bars

Option Description

Create rebars

Select whether edge bars are created.

Standard rebar

Define the grade and size of the first bar group.

Create second group

Select whether to create a second bar group.

Define the grade and size of the second bar group.

End conditions on edge

Define the shape and dimensions of the bar ends of edge bars. You can define both sides separately.

Select a shape:

End conditions on opening

Define the shape and dimensions of the bar ends of opening bars. You can define both sides separately.

Select a shape:

Number of bars and spacing

Description

1

Define either the spacing value or the number of edge bars. You can define the first and second bar group separately.

2

Define which bars are created.

The bars illustrated as dots are not created.

3

Define the edge distances for the groups.

Edge bar shape

Select the edge bar shape in relation to the input points.

Consider openings

Select whether openings are taken into account.

Hook length

Define the length of the hook. You can define the hook length if you have selected to create hooks in Consider openings.

Advanced tab

Use the Advanced tab to define the properties for edge bars, pin bars, and rebar assemblies.

Edge bars and pin bars

Option

Description

Comment

Add content to the comment UDA.

Name

Name that is shown in drawings and reports.

Class

Class number for the rebars.

Serie

Prefix for the rebar position number.

Start number

Start number for the rebar position number.

Rebar groups

Select the number of edge bar groups. Define the grade and size properties on the Edge bars tab.

Extra rotation

Select how the pin bars are rotated.

Option Example

No

Pin bars are not rotated.

Around X

Pin bars are rotated around the x axis.

Around Y

Pin bars are rotated around the y axis.

Create as rebar assembly

You can add the created reinforcement as a rebar assembly to the cast units with a predefined assembly type, name, prefix, and start number.

Option Description

Create as rebar assembly

Select Yes to create all reinforcement as one rebar assembly, and to include it to the cast unit of the input part.

Rebar assembly type

Select the rebar assembly type.

If you do not select the type, the default value of the rebar assembly is used.

Name, Prefix, Start number

Define the name, prefix, and start number.

If you do not define these, the default values of the rebar assembly are used.

Attach to

Select which part the rebar assembly will be attached to, the main part or the neighbor part.

Define the neighbor part selection criteria on the Configuration tab.

Configuration tab

Use the Configuration tab to define further settings for controlling border rebar creation.

Configuration settings

Option Description

Bending radius

Define the bending radius for pin bars and edge bars.

  • rebar_database.inp

    The radius values defined in the rebar catalog for main bars and tie/stirrup are used.

    The rebar_database.inp file is by default located in the \profil folder.

  • Relative to diameter

    The radius is calculated by multiplying the rebar diameter with the entered value.

  • Bending radius

    Define a fixed value for the bending radius.

Detect outside geometry

Define how part cuts are detected inside the concrete part. Typically, this setting is needed when the concrete part has recess cuts.

Use the Distance in material setting and the options in the position in plane list to move the plane that is used in searching for part cuts.

The plane location is visualized in the model if you set the Draw geometry with profiles to Yes.

Draw geometry with profiles

Select whether to create construction lines to visualize the location of the part cut detection plane.

You can change the location in Distance in material.

Draw axis

Select whether to visualize the internal coordinate system of the component.

If you select Yes, three small parts with a round diameter are created at the component axis, starting from the origin. This can help to set up the component, and to give more clearness in component orientation.

Select No to remove the visualization.

Attach pins to

Attach edge bars to

Select whether the pins and edge bars are attached to the main part or the neighbor part.

Find neighbor

Define how the neighbor part is identified, by name or by class.

Cast unit geometry

Select Yes to create reinforcement for all relevant concrete cast units outside the selected part.
