I am making Fitting the picture below.

Please if you can help

To make accurate

Because it is necessary for my job

AutoCAD file attached..

Hi all

I repeat ,It was created Fitting.

Please download the attached family

If there is a better way guidance

One person you please answer my question 

[bit000]

could you save lower version of revit. (2014)

hi

no-Sorry-i have Revit 2015.

I looked at your family and screenshot. If I look at your family the bend side arm does not look like the one in the screenshot.

In the screenshot you see that center or R1 and R2 are in line. Further the curve of R1 and R2 end in 'vertical' line. Therfrore you would have to modify that extrusion.

As you can see I also introduced an offset for R2. To create width of duct equal to W3, R2 center has to be offset from R1.

By doing this the duct start to look more like the one in the screenshot.

More should be done to this duct. Setting some of the values will work only upto a certain point. After that the model will break.

So more constraints have to be added, formulas to be added or values limited within certain range. But to decide which/how would require more information on the real part.

Hopefully this will help you along.

hi and Thank you for taking the time Enlint

But the family fails.

The drawing automatically routing(Generate Layout) I want to use my fitting.

But fails.

So that: 

1000 CFM is an example entry and then, 200 CFM output to be the branching The rest continue straight.

I put a lot of time on this problem ,But I always fails.

I feel uncomfortable.

I do not often create duct families myself. But hereby some tips that I found useful when creating those families. First of all study existing families, it might set you on the right track. Constrain your model. This means lock you extrusions etc to the reference planes/lines.

For families with connectors.In most cases make sure that at two of the connector intersect at the origin. Pay attention which connector you assogn as primary.

So I quickly did some modification to your family. Added constrains to some extrusions. Made sure that two of the connectors are on the origin axis (added eq constraints).

Then inserted into project

I also do not find it always straightforward and need some experimenting to get it working..

More testing has to be done and maybe more constraints have to be added. But hopefully this will bring you further
