Revit RFA - Extrusion modelling

[Luke.Kemel]

All,

is it possible to detail an extrusion that is on 4 different ref planes?  - See attached Zip file.

The rectangular lines sketched within the pdf show an indicative panel layout. in order to achieve my goal, i need to get this drawing from model lines to extrusions. due to the complex geometry and various planes i cannot work out how to model my extrusion into the rfa.

I have a curved soffit design that starts at a vertical plane (90degrees) and slopes around a corner before becoming a horizontal plane (90degrees). The facade panels are twisted round the corner and i need to be able to present this curvature/twisting to the customer with appropriate panel sizes and structure. 

(Unfortunately i am unable to post the .rfa file here due to client confidentiality/data protection.)

i am not really after a solution on how to detail the soffit, just a bit of insight on how detailing an extrusion on different planes is achieved. if this cant be done, does anyone have any bright ideas on how i can achieve this? 

i have thought about using a sweep, but again an cant seem to get this to work. 

any suggestions/solutions will be greatly appreciated.

Instead of posting a .zip file to download, maybe you could  use the Photos icon and post images as .jpg files.

I have attached them within a .zip file because they are PDF files. the photo icon does not support PDF files, only JPG files. 

the quantity is also too high, as the max number is 3 attachments

Here are the pictures as posted by the OP for what they are worth.

From the images I really do not understand what the question actually is. I am going to suggest conceptual modeling tools I think. They could make a sweeping kind of surface that goes out of plane and then is panelized, which is as best as i can tell from the images is what you want.  Beyond that the images are so out of context it is difficult to understand what exactly the question even is.

I understand the images are not very useful (that was never the intention), but i also don't expect you to fully understand the sweeping motion of this scheme based on 2D images. As mentioned, i am unable to post the .rfa file here due to date protection. 

If you can refer to my my first post, i am not after a solution to the attached images. They were sincerely for a very base understanding that the panels i am working with are sweeping and and have a twist through the center that is only visible in a 3D view. 

Due to the panel geometry, when i begin to create an extrusion i can only select one corner because the other three corners are not associated with the work plane i have set. Therefore, i will revert back to my initial question... Is it possible to detail a rectangular extrusion where all points do not cross the reference plane that is set? 

Is there a way to create a rectangular reference plane so i can outline the panel and detail the extrusion this way, or am i restricted to the reference line tool?

Yes...it's called a conceptual mass family.

Model the form as a Generic Model adaptive or a Mass, divide surface using reference planes, then create another Generic model adaptive for the panel, load it in the host surface, place on the surface nodes and use Repeat to populate it. You may need a few types of panel family (3 points, 4 points, 5 points) to cover the odd shaped panels.

Thank you. this is greatly appreciated.
