How to lock the slope reference plane endpoint to the interface point

How to lock the slope reference plane endpoint to the interface point? The two red line end point not go up together... I want the model look like the cad file but the  slope part can not fit and got some error...

attached revit 2020 file , thanks.

See this video by @fabiosato using a reference line and equality dimensions from each reference plane to each end point.

Hi, I tried the video method, done but only could rotate the element, could not make the element parameters... Can it be using in reference plane not using in reference line?

I don't think you can do it with a plane.

To align and lock elements to a reference line save them as separate families and then insert them into your fitting family as nested sub-families.

Maybe there's another way to do it but I rely on @fabiosato , @L.Maas , @robert.klempau  etc for advice on how to build families. Or else obtain a family from someone else (Wavin?, Geberit?) and see how they do it.

See the attached document as well for advice on creating fittings.

Hello,

To make a flexible angle family, you must use reference lines, reference planes do not change the angle.

Also, the orientation of the fitting may affect how it works.

The primary connector should be facing the left side.

For bends, the secondary connector should point to the upper right quadrant.

For tees, the central connector should point to the bottom direction.

And another important piece of information, the crossing of the pipes axis must be at the family insertion point, where the reference planes with Defines Origin checked, cross each other

Use ref lines, not ref planes.
