2D Reinforcement

 

Naviate Structure – 2D Reinforcement

There are two different ways to work with 2D Reinforcement:

  • Place all reinforcement symbolically using 2D Reinforcement Rebar functions.
  • Place all rebars in 3D with Revit. Then use 2D Reinforcement Rebar to create symbolic rebars and place reinforcement text in the detail views. (Norwegian version only)

It is also possible to use a combination of 3D reinforcement and symbolic reinforcement

 

 

Placing symbolic rebars

The main dialog for placing symbolic rebars is shown below. The dialog shown here is for placing rebar with a distribution line, but all dialogs are more or less the same. There are small variations, and they are specified in the list below the dialog.


 

Bar mark parameters are spesific to the bar mark and is fixed after a bar mark is placed in the model. To change these values use the revise bar mark function.
Note that in the dimension list there is a small button for each value. Use this button to measure the dimension in active view.

The total number of bars with this bar mark in the schedule is multiplied with the “Number of Parts” value.

 

 

Instance Parameters

Material Take Off (MTO)                    
If on, the instance of the bar mark is counted in the schedule. The symbolic representation of a rebar should only have one instance with this set on.

Number Of Bars
The functions with a distribution line calculate this value automatically. In all other functions this must be set manually. When placing bars in elevation there is also a calculate button next to this value that brings up a calculator that can be used to calculate number of bars from distribution length and center distance.

Multiplicator
The number of bar marks of this instance of this bar mark is multiplied with this value in the schedule if MTO is on.

Tag Element
If on, the placed instances are tagged. Usually the tags must be moved afterwards.

Arrow Head
This value is shown symbolically in plane and in tags.

Placement
This value is shown symbolically in plane and in tags.

Scale
When placing rebars in plane or in section it’s possible to set a scale. In the section function the rebars is placed with the bar diameter multiplied with this scale. In plane the size of the symbols (Into plane, out of plane, etc.) is defined by this value. In the plane functions this value is set to the view scale by default.

Angle
When placing rebars in plane and in elevation they are rotated by this value. In elevation the rotation happens after the instances are placed and in most cases it’s better to use standard Revit functions. In plane the symbols on the plane line is set according to this angle. There is also a drop down here where it is possible to select top (0°), bottom (180°), left (90°) and right (270°). When placing multi planar rebars the only possible values are side or front.

Center Distance
This is the center distance between the rebars.

Offset
The instances are placed with this offset value.

Total Running Length
This parameter is only valid when placing running meter. It’s explained in more detail in the running meter chapter.

Running Meter Factor
This parameter is only valid when placing running meter. It’s explained in more detail in the running meter chapter.

 

 

Place Bar with Distribution Line

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a line based symbolic instance of a rebar in plan into active view. The number of rebars is calculated based on the center distance and the length of the distribution line.

 

 

Place Bar in Plan

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a symbolic instance of a rebar in plan into active view.

 

 

Place Distribution Line

This function only places a distribution line with no rebars associated with it.

 

 

 

Place Section Bar with Line

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a line based symbolic instance of a section of rebar’s into active view. The number of rebars is calculated based on the center distance and the length of the distribution line.

If “Display all sections” is checked in the main dialog, all the sections are drawn. If it’s not check, a distribution line is drawn together with just one rebar in section.

 

 

Place Section Bar

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a single symbolic instance of a section of a rebar into active view.

 

 

Place Bar in Elevation

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a symbolic instance of a rebar in elevation into active view. When placing bars in elevation the dialog also has a button next to number of bars. Clicking this button opens a simple calculator for calculating number of bars based on distribution length and center distance.

In the Swedish version it is also possible to show symbols on the ends of rebars in elevation when the bar mark do not have hooks. The symbols are defined the same place as hooks. These symbols are instance based.

 

 

Running Meter Tag

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a tag representing running meter reinforcement.

This function can be used in two ways:

  1. Select a filled region element representing the area where the running meter reinforcement is to be placed, before starting the function. Then the Total Running Length is automatically calculated based on the Center Distance and the Running Meter Factor.
  2. If a region is not selected before calling the function the Total Running Length must be calculated manually. The Running Meter Factor does not have any effect.

 

 

Running Meter with Line

Use this function to place running meter rebars with a distribution line. Total running length and number of bars is calculated from the center distance, running length and the running meter factor. The formulas for calculating are defined in the family. And the running length is the length of one run of rebars.

 

 

Running Meter Symbol

This function places unintelligent symbolic instances of rebars. The parameters that can be set are: scale, placement and symbol. The symbols can be dragged in all directions after placement. It is possible to place four different symbols: In plane, in plane with distribution line, section and section with distribution line.

 

 

Reinforcement Text

Opens the main dialog where type and instance parameters are set. When pressing “Place” the user can place a tagged empty symbolic instance of a rebar in elevation into active view. This means that only the tags are shown. This function is useful if none of the other function makes the desired result. Use standard Revit detail drawing to create the symbolic lines and then place reinforcement text to create the tag and get it reported in the schedule. The running meter symbols can also be used to create the symbolic representation.

 

 

Generate Rebar Symbol from 3D Rebar (Norwegian version only)

This function creates a symbolic rebar symbol from a Revit 3D rebar element created with Revit Structure. Either pre-select one or more 3D rebar before calling this function, or pick a Revit 3D rebar afterwards. It’s not recommended to select more than one 3D Rebar. Afterwards set the instance parameters in the dialog show below.

Also note that the dialog has an information window where information about the 3D rebars are given. In the dialog below the selected rebar is located in a floor and 2D Reinforcement has detected that there exists two sets of similar rebar in this floor. And when this is the case the placement is automatically set to Both Horizontal. If the rebar were located in a wall placement would have been set to Both Vertical. Also if the selected 3D rebar already has a symbolic representation Material take off will automatically be set off.

It is also possible to keep 2D Reinforcement from auto detecting these variables by unchecking Use 3D information.

There is another special option here; only tag element. If on, the 3D rebar is not hidden in the view and a symbolic representation is not drawn. Only a reinforcement text element is placed. This is useful if the 3D rebar is shown fine in the view and you do not need to have a symbolic representation.

Also note that number of bars is only used when the 3D rebar is placed as single layout.

The scale defines the size of end symbols when placing rebars in plane.

Rebar symbol from 3D will either place a symbolic rebar or just place reinforcement text elements, depending on the 3D rebar.

If the 3D rebars are placed with a distribution and viewed along the distribution path, they are hidden in active view and a symbolic representation will automatically be placed instead.

If the 3D rebars are viewed perpendicular to the distribution path, in section or as a single bar, the 3D rebars are not hidden in view. A reinforcement text is then placed in the view.

The function automatically detects the bar mark and the shape code. The bar mark is found from the 3D Rebar parameter called “Mark” or “Schedule Mark”. Usually the “Mark” parameter should be used, but if this parameter is empty 2D Reinforcement uses the “Schedule Mark” parameter.

If the 3D rebar is unknown a dialog is shown where it’s possible to select from the known shape codes. Here it’s also possible to select Running Meter. If running meter is selected no symbolic representation is created, the 3D rebar is not hidden, only a running meter tag is placed in the view. To get a symbolic representation, the running meter symbol must be placed manually and the 3D rebar hidden.

 

 

Administrate Bar Marks

This is a set of function for editing and administrating bar marks.

 

 

Edit bar Instance

Change the parameters of a bar instance. This function should always be used to change values of instances. Never use Revit’s Properties window.

 
 

Revise bar mark

Revise a bar mark. This is the same dialog used when placing rebars. The dialog will not close when pressing the Revise button. This is intentional and makes it easier to revise several bar marks.

 
 

Edit scale

Changes the scale of symbolic rebars in active view.

 
 

Change Tag Size

Changes the size of the ISY CAD Rebar text tags. This function will change the tag size of all the tags in the entire model.

   

Rename bar mark

Rename a bar mark.

 
 

Renumber bar mark

Renumber a series of bar marks with a delta value and/or a new letter. This function can be run in two different modes.

If no rebar instances is in selection set when the function is started the user must enter bar marks in the to and form text boxes. All bar marks in the entire model between these will be renumbered.

If one or more instances are in the selection set when starting the function, only the selected instances will be renumbered. This is an ideal function to use if you copy rebars from one floor to another and wants to give the newly copied rebars new bar marks.

 

    

Delete bar marks

Delete bar marks selected in list and all its instances.

    

Verify rebars

Verifies that the 3D rebars and their symbolic representations are coherent.

   

Reload symbols

Reloads all 2D Reinforcement families in the model an recreates the intermediate file used for figures in preview and schedule.

 
 

Purge symbols

Delete all unused bar marks

 

Additional Functions

This is a set of function to create bar mark schedules and editing and list bar marks.

 

Bar Schedule

This function creates a bar schedule from the symbolic rebars in active view, sheet or entire model. The function uses Word documents as templates and can create the schedule as PDF or Word files.

 The dialog has the following options:

Output file. Name of output schedule file.

Output file format. Either Word or PDF. Word files can be doc or docx.

Report. Entire Model, Active View or a View/Sheet set. If entire model is selected. All bar marks in the entire model are listed.

Project data may be altered in the following dialog, Project settings in Create Bar Mark Schedule

 

 

List bar marks

This function opens a dialog that lists all bar marks in the model. The dialog is modeless, which means that it can stay open all the time.

 

List bar marks has the following options:

  • Select. Adds the selected bar marks to selection set in active view.
  • Entire Model, Active View or a View/Sheet set. If entire model is selected. All bar marks in the entire model are listed. If active view is selected only bar marks present in the active view are listed. The last option is View/Sheet set, this will list all bar mark present in selected View/Sheet Set. If no sets are defined in the model this option will not be shown.

2D Reinforcement Options

General

Regional settings

Select the country standard used for shape codes and schedules.

Pre calculate instance parameters

If unchecked, the length of bar in plane is not pre calculated. This will speed up placement of families, but the real length of the bar will not be set until after all instances are placed in the model.

Attach tags with free end

If checked, all tags are attached with free end.

Schedule

Verify 3D linkage when creating schedule/list

If the function for creating symbolic from 3D rebars is used this will run a test to ensure that all the 3D rebars has not changed since the symbolic rebars were created. Note that is this is checked, creating schedules and lists will take longer time.

Calculate number of running meter bars

If checked, number of running meter bars is calculated in schedule. The length of one bar is also shown in the length columns. If not checked, these fields are left blank.

Show figure as

When creating schedules the figures can be created with either letters or the actual dimension.

Figure resolution

The figure in the schedule is created as a bitmap. Use this slider to change the resolution of the birmap.

Figure text size

Use this slider to change the size of the texts in the figures in the schedule.
