Adding parameter for dividing circular free form rebar exceeding 12m lenght

[REDO10]

Hi All,

Hi @ovidiu_paunescu 

Hi @RDAOU 

In my circular tank project my reinforcement are mostly circular and I used the free form rebar option to draw the different shapes I have (see the picture bellow).

My problem is that the circumferences of my circular rebars exceed 12m and the rebar unit length is 12m so how to divide the circumferences over 12m to compute the exact number of bars having 12m and put their number in the schedule? (is there any parameter or formula to add to the free form rebar to split the length if it exceeds 12m?).

Thanks.

It seems you have 210 rebars (540-330) who are not assigned to a partition.

That is very dangerous as you now can't see what host they belong to. You should always partition them as soon as you model your rebars.

Hi All,

Hi @semi , Hi @ovidiu_paunescu 

how can I invert the numbering between two rebars set belonging to the same partition shown in the picture bellow? ....Can I do that by assigning a schedule mark for each rebar set?

Thanks.

[semi]

you can do this with a free add-in called optiBIM

@semi 

No possibility to do it in REVIT only?

[semi]

No, either with Dynamo or 3rd party add-ins.
Why would you want to change the number btw? If you partition correctly, Revit gives each rebar it's own unique number.

I would like to display number order that I want

Hi @semi 

Hi @ovidiu_paunescu 

why do I get two different rebar numbers, while both rebars are the same (quantity, length)?

Note: I made a symmetry in relation to the Tank's center-line  to create the other side of the host including the rebars, does this have an influence on the numbering?

how to solve this problem?

Thanks.

[semi]

are they in the same partition?

[REDO10]

@semi 

Yes they are in the same partition

[semi]

then there are 2 possibilities:

-1. there is a slight difference in rebar length, Ø

-2. the tag numbers are not referring to the rebar number tag parameter

[REDO10]

I don’t think so! all rebars's characteristics are identical (see picture bellow)

  

[semi]

ok, but what partition are they in?

send me the file

[REDO10]

Hi @semi 

Hi @ovidiu_paunescu 

sorry for my late reply

they are in the same partition called "Partition4"...take a look at the view called "fondations" in my attached file bellow to see well the problem.

at the same time give me your opinion on the numbering and tagging  of my rebars.. Is there something wrong or something I need to correct?
Note: see these views, please: (detail1_ferraillage-radier); (detail2_ferraillage-radier); (detail3_ferraillage-radier); (detail4_ferraillage-radier); (detail5_ferraillage-radier) and (Coupe 1-1-Structure)

Thanks.

Hi again,

so the reason for causing the difference in number is because the rebars mutually are already different in the rebar set itself.

You made a rebar set of 3 freeform bars in one ellipse which causes the lengths to be different:

When I change this to a set of one single bar I get the correct length:

So the reason for the difference in rebar numbers is because of this. You are not exactly using the exact same rebar lengths because they already differ in lengths mutually.

I tried mirroring these sets, but it still ends up in different rebar numbers.

I also noticed that you used a straight rebar shape "00" for this.

You could try mess around by using rebar shape "75":

You've now only placed 2 straight rebars with the length of half the circle without an overlap which is wrong.

You should use a rebar shape of a circle and make them overlap each other.

I do know revit is having trouble with generating an overlapping circular rebar.

my circular rebar are distributed according my gusset's geometry and it's logical that they have variables lengths  because gusset's radius increase along rebar N° 46 and I can not draw each of them as a single bar!!! ...the reason I used free form rebar to draw them in a single set.

how can I use rebar shape "75"? ...is it possible to select it in the free form rebar? or you are talking about the single bar case??... can you made a screen video for me how to do that?

I know that I should overlap my rebars and I asked precisely this question to @ovidiu_paunescu  in this same topic and I could understood that it is complicated to do it in REVIT and I have to go through dynamo to do it and as this is only my first project in REVIT I intend to do it later

Thanks.
