FREE FORM REBAR

[Anonymous]

As you can see, the height of left side and right side of this wall is different

When I do the reinforcement with free form, I'm having a problem.

If I do the maximum spacing 400, the left side wll have 400.

Left side is the problem.

No matter how many rebars I want, Free form wants to keep the number of higher side.

I want to add new rebars every 400.

Is there any way to do that?

Thanks guys Happy new year!

Check in the Contextual Ribbon to see if Varying Rebar Set is selected.

Could you give more details about this? maybe a sample file

I'm guessing you are referring to the vertical bars.

Are you trying to get the bars to face each other two by two?

The way free form rebar works, is that the first bar and last bars obtained at the intersection of the host surface with the start surface and end surface respectively. Then the rest of the bars in the set are obtained by splitting the distance between the two according to the layout settings.

The outer and inner faces in your example have different lengths, so the using maximum spacing will divide the length such that the distance between the bars doesn't exceed 400.

You can adjust the offset of the first/last bar to the start/end faces by using edit constraints.

I can give you a more exact answer if you add a sample file

Thank you for replying

I was not talking about the inner and outer side

In the file I've attached, Rebars are only one side

I really hope there is a way to make this happen

The result you are looking for would easily be accomplished using shape driven rebar, if the wall was straight.

For free form rebar, you must not select the inclined face as start or end, because the bars will be paralel to that.

What you can do, is create an additional object to host the set - sweep with the same profiles, and then trim the set to the inclined face in the wall you are trying to reinforce.

Here's how this looks in your example:

I thought I have to adjust the bars one by one to the inclined face but it doesn't look like you did that way

How can I trim the rebar set to inclined face?

I forgot to mention

It's really simillar with the way you showed me last time ( placing rebars in the round curved column)

I should be more creative like you to play with Revit

Thanks
