Swept Blend with non square profile

Hi,

I'm trying to make a family similar to below. I can do it as an adaptive family but I don't really know how to use the adaptive family. I am quite competent with Generic Model family creation however I don't know how to get the profile similar to the attached. 
I need to do a swept blend with a profile that can be rotated at an angle to the path.

Anyone have any suggestions? I'm very confused so apologise if I have explained it poorly.

Think you can figure it out from the attached?

Thanks for the reply. 

I may have explained it very poorly.

My issue is I want to stay away from an adaptive family because I want to nest this with other Generic model families. I was wondering if its possible to do a swept blend similar to the attached screenshot below. 

BLUE being the profile (a basic square) and RED being the path of the sweep. As seen below, I need to keep the profile vertical however I want to create a parameter to adjust the "SKEW" angle.

Why are you in an Adaptive Template then? Anyhow, you can create that Sweep Blend by pathing along a Ref. Line in a regular Template.  

 

...wait a minute.  I misread you screenshot.  You'll need to cut your form with a Void Extrusion at both ends.  

 

 

....is this what you are after?

Man, you got some Escher sh*t going on here.

haha the geometry has been doing my head in for a while.

What you have there is what I come up with as well. But its not what i need.

This is the best way i can explain it:
(Thats also the reason I attached that adaptive family. To explain the geometry and work out if I could do that as a generic model)

Above.... a-a is the same level and b-b is the same level (constant)

That is just a basic swept blend.

YES! That’s it!

 

So the path is not straight and the profiles are offset?

Would it be possible for you to create that in revit 2021 and send over the file so I can investigate? I can do 2022 if you wish but would just have to download it from my suite.

 

thanks so much. Keen to see how it flexes

Sounds more like

  • a line based extrusion w
  • 2xAngle parameters to tapper each end

Okay then -- so we're back to what I showed you in Message #4.

Ah! I see now. 

 

Can you help me out with this one since you're on a roll now?

Thank you ToanDN!

That is the geometry I am after! Really appreciate the quick response on this.
