[CAD ID] How to Create a 3D Drawing (Rebar Drawing)


I want to make a 3D section for Rebar drawing using ISO View.



Using the 3D View function of CIM, you can create a 3D section in the form of an isometric view (ISO View).
In addition, you can create customized drawings for Rebar drawing use for drawing artifacts.


Based on the example in the following explanation), based on the section created in CAD INFRA-DESIGN, add the title, dimension line, symbol, etc. of the drawing to make the drawing.

Figure. 1 Section configuration

ㆍSelect the section to be used in CIM View.
    If you double-click the section name in the CIM View Mode - Work Tree window, the section is 
    selected and zoomed in.

Figure. 2 Apply Style and Scale changes

① Drag the View Box to select it.
② Set the view scale to 1:50.
③ Find the registered style name in the Style item and select it.
     In the example of explanation), InfraDesign_Style S05 (ISO Rebar) as selected and applied.

Figure. 3 Application of changes Update

ㆍIf there is a change such as style, right-click on the CIM View Mode section name to display the
    Update dialog box.
ㆍIf you select the Update item, the drawing changes are updated.

Figure. 4 Apply changes Update result

Figure. 5 Select foundation reinforcement and set visibility

ㆍIn ISO View, where rebars are modeled, it is recommended to classify rebars according to the
    user's environment and make drawings.
ㆍIn the example of explanation), the foundation B1 rebar group of the pier is exposed.
    ① Drag the View Box to select it.
    ② Hide all rebar annotations, find and show individual rebar numbers according to drawing

Figure. 6 Create rebar annotation (1)

ㆍThere are two methods of creating reinforcing bar annotations in the 3D section created
     with ISO View.
ㆍIt is divided into SingleAnnotation (SA) / MultiAnnotation (MUA).
    According to the display range of the leader line of the reinforcing bar annotation one rebar or
    grouped rebars are displayed separately.

Figure. 7 Create rebar annotation (2)

ㆍ Figure. In the example of explanation in 7), rebar annotations and ranges are displayed for
     B1 rebar group using MultiAnnotation.

    How to use is as follows.
1. Enter the command MultiAnnotation (MUA)
2. Option selection [Line(L)/Polyline(P)]
    : [L] input * This is an option to indicate the range of the rebar by drawing a line.
3. Insertion point designation / end point selection : * The starting and ending positions of the
     rebar annotation range.
4. Select the Base point : * Designate the location where the reinforcing bar annotation
     will be created.

Creation of annotation for pier foundation B1 rebar group.

Figure. 9 Section copy

Copy the same section and use it for the section where the column reinforcement is visible.

Figure. 10 Column bar selection and visibility settings

In the copied section, the existing reinforcing bars are hidden and the column P1, P3  rebar groups
    of the piers are shown.

Figure. 11 Create rebar annotation (3)

In the case of column reinforcing bars in which multiple reinforcing bars are overlapped,
SingleAnnotation (SA) function is used to display one representative rebar annotation.

Figure. 12 Create rebar annotation (4)

ㆍExample of explanation) uses SingleAnnotation to display reinforcing bar annotations and ranges
    for  P1 column rebar group.

ㆍHow to use is as follows.
1. Enter the command SingleAnnotation (SA)
2. Objet Select : * Select the rebar group to create a rebar annotation.
3. Insertion point designation * Select a representative rebar for which reinforcing bar annotations
    are to be created among rebar groups.
4. Text point designation : * Designate the location where the rebar annotation will be created.

Figure. 13 Create rebar annotation (SingleAnnotation).

ㆍ A representative single rebar annotation has been created for the column P1 rebar.

Figure. 14 Create and utilizing rebar annotations. (Video)


ㆍThis is a video demonstrating the creation of rebar annotations using the
    MultiAnnotation (Foundation part) / SingleAnnotation (Column part) function.

Figure. 15 Section copy

Copy the same section and use it for the section where the rebars of the coping part are visible.

Figure. 16 How to set representative rebar (1)

ㆍIn ISO View, where multiple rebars are modeled, it is possible to select representative
    rebars among grouped rebars for visibility.
ㆍ For representative rebar, select INFRA-DESIGN > Rebar Group Setting > Rebar Group Setting
     Shortkey (RG)

Figure. 17 How to set representative rebar (2)

Select group object : * Select a representative reinforcing bar group.

Figure. 18 How to set representative rebar (3)

Select representative Rebar or [Undo(U)] : * Select the rebars to be displayed as representative

Figure. 19 Coping part representative rebar setting

ㆍIt has been set as a representative rebar for the coping part of the pier.

Figure. 20 Create rebar annotation

ㆍCreate rebar annotations according to the user environment.

Figure. 21 Rebar Group Setting. (Video)


ㆍThis is a demonstration video of setting up a representative rebar.

Figure. 22 Example of rebar annotation creation method using 3D section

EX.1 This is an example of a cross-section using the Multi rebar Annotaion
   (Group rebar annotation) functionon on the foundation part of the pier.
EX.2 This is an example of a cross section using the Single rebar Annotaion function in the
    column part of the pier.
EX.3 This is an example of a section using the Specify representative Rebar and Multi rebar
     Annotaion functions in the coping part of the pier

Figure. 23 Composition of the drawing (Rebar drawing)

ㆍCreate the cross section to be drawn by referring to the contents of Fig.1 ~ Fig.23.
ㆍConfigure the Sheet to use and move it to CAD View Mode model space.
    Reference link [CAD ID] How to Create a Sheet
ㆍIn the example of explanation), I copied and applied the sheet applied in
    [CAD ID] How to Create 2D Drawings (Rebar drawing)
ㆍDrag & drop the section in the CIM View model space and place it on the sheet.
ㆍCreate a drawing by placing the section according to the user drawing configuration, and
    adding the title and symbol of the drawing.
