Visibility and reinforcing mesh question.

Hi everybody, I am not sure how to deal with this issue, I hope some brilliant minds can help me here. 

Please see the screenshot below. (This is part of NU Girder) 

jizeliu_0-1695411628805.pngjizeliu_1-1695411654227.png

The bottom green and sky blue rebars are custom made mesh (see screenshot above for mesh detail). Made by 2 different sizes of MD bars. Each piece of mesh is over lap to cover the entire girder.  
 
Even if each mesh is made of many bars, it still needs to be considered as one piece.  I decided to approach this by making the mesh as a generic family. Also base on the very limit knowledge I have for the Revit. I don't think it's feasible to do it by using revit  rebar tool. 
Here is the problem, when I switch the visual style to non wireframe. ALL the mesh is no longer visible to me. 
 
How do I overwrite this or should I create the mesh in a different way.

You can edit sheet reinforcement as per the following advice.

 

https://help.autodesk.com/view/RVT/2023/ENU/?guid=GUID-098B9B94-B06D-4455-BDA6-182AB2E1ECEA

 

As regards drawing this in Revit using Rebar that would be feasible just cut a section and draw the coat hanger shape and add a spacing value so it distributes along the length of the host and then place longitudinal bars for the hanger support bars, again in the section

Hi @jize.liu 

 

You could try to model that using a bent fabric sheet

https://help.autodesk.com/view/RVT/2023/ENU/?guid=GUID-098B9B94-B06D-4455-BDA6-182AB2E1ECEA

https://youtu.be/fb0CKNGTRGk

 

For your example it could look like this

ovidiu_paunescuautodesk_com_0-1695458554830.png

To sketch this, go to Structure tab > Reinforcement panel and click Fabric Sheet

Then in the Modify | Place Fabric Sheet ribbon click Bend Sketch

Sketch the shape

In the type properties you can find an overhang property. You can use this to define the length by which the longitudinal bars overlap the next segment.

ovidiu_paunescuautodesk_com_1-1695458740674.png

 

In the properties palette there is a parameter for defining the longitudinal cut length.

If you do use the Fabric Sheet > Bent Sketch method

In Revit 2021 you have the option for Bent Fabric sheets in View Visibility as you would with Standard Rebar so seems it would cover all your questions.

 

jay_colcombe_1-1695459674022.png

 

This is also the case in Revit Revit 2024 

 

jay_colcombe_0-1695459482278.png

 

And you can turn the Boundary off via Visibly Graphics in

Thanks guys. I appreciate all the detail information and screenshot. 

Sorry I have a follow up question. If I use Fabric sheet tool:

  1. can I add new wire type? 
  2. how to control the wire spacing? This is custom made mesh(for example: 11 SP @ 75MM then switch to 4 sp @ 100mm. )

you can create you own Mesh/Fabric sheet

 

In the Project Browser > Families >  find a sheet close to your specification > Right Click > Duplicate > Type Properties and edit the Parameters specific for your needs

 

jay_colcombe_0-1695825629101.png

 

You can use the Precast Tools to create you own Custom Fabric Sheet if this is not satisfactory

Sorry I think I am been very challenging to you . I see there are a lot to learn. So I decide to try custom fabric sheet. I use rebars tool drawing the rebars and placing it at the right spacing. I assembled all the rebars and then click the custom fabric sheet button. I got a error message.

As the message the Precast method will only allow this in a single host can you confirm the rebar is fully contained within a single slab or wall?

 

As regards the custom Fabric Sheet, are you stating the bars change diameter and spacing in the same direction?

If it is regular spacing in the X direction and the regular in the Y this is achievable by duplicate a standard sheet even with different bar diameters and spacings in the X&Y

Thank you for your help. 

For mesh information please see screenshot below 

As you can see, 2 type of MD bars (Horz. & vertic.)  with different spacing. 

 

 

jizeliu_0-1695837048631.png

 

For the Precast method, It's generic models family I made, shape as a NU girder, not walls or slabs. If my understanding is correct, i drawing the rebar inside the girder, so I think they are  fully contained. (visually )

I think you are outside the limits of the software but happy to be proven wrong.

i would approach it using standard bars and and shapes and create a sheet using single bars then create a Group or Assembly and use the sheet reference as the name so you can count the numbers used and then manually place or copy the Groups/assemblies along the elements/hosts!

Hopefully the Revit Gurus can find a better way of achieving your requirements.

I will mark this as "answered" even we don't have one yet, it's seems like this is a important thing in this planform. 
Also huge thanks for your patience to explain everything to me. At least I learned stuff. Thanks for your help,  I can create and add my own wires bars in the system now. 
 
I already tried "group" or " Assembly" tools
For Assembly : I am use assembly tool to create shop drawings. so my box girder with all the components are already one assembly. It's seem like a assemblies can't nest or contain one another. so If I assemble all the rebars that mean these rebars will not show in my box girder assembly view. 
 
For Group : It seems like I can include the rebars group in a girder assembly. However, in the assembly view, all the rebars show as ungrouped somehow...but same bars show as grouped in the structural plans view. Also rebar schedule will not count per group only per each girder assembly .  
 
The mesh tools / custom fabric sheet are already build in the programs. Let's hope one day they can enhance it.
