Reducing elbow swept edge blend line not align

[pe_simon]

I create it by  elbow swept. Thanks.

If it is a 90 degree elbow then the path must be a quarter of a circle.

[pe_simon]

It is a reducing elbow 50mm x 25mm, how can I fix it?

Hello,

If you can share your family, it will help us to help you.

[pe_simon]

Okay,  sure.   A must 43mm, B must be 50mm. Others can change. Thanks a lot.

Like this?  If so, see attached Revit 2002 family (I don't have 2020) and you can replicate it in your original 2020 file.

Can not open revit 2002 version file...

[pe_simon]

Who can update it from revit 2009?  And then I try to update it to 2020 from version 2009.

You can easily fix your family by yourself.

Just do the following:

Go to Family Editor

--> tab: Ref.Level

--> select the Swept Blend

--> press “Edit Swept Blend”

--> press “Sketch Path” 

--> select the magenta line representing the Sketch Path

--> you will see a tiny circle (near the middle of the path) that is slightly off axis

--> drag it to the dead center of the reference lines cross

--> press the green "check" , and "check" again

--> your family is OK and aligned

It's Revit 2022, not 2002 (typo). If you cannot open it, then you can fix your file yourself by re-drawing the swept blend path as a quarter of an ellipse, which sets the profile 1 and profile 2 planes align with their target ref planes, and that should be it.

Thanks, done it but not same as your figure??

[pe_simon]

Where can find the magenta line??

Sorry the quarter ellipse should be between the inside faces of the two rings.

Fixed, Thanks!
