Urgent problem to solve (twisted tower)


#1

Dear Dynamo Friends,

I am currently working on my graduate thesis . I do this in Revit 2018.2 and Dynamo 1.3.2.2480.
I am trying to create a twisted tower definition using a elliptic profile that have been lofted to create a solid. The point is the tower is not https://1drv.ms/x/s!ArJ2ZwPsSjN0nQJJig0ynPC3Jxsj twisting linearly, I calculate the degrees of twisting as list in a excel file. Any help with this would be greatly appreciated. I am uploading the file with this post.

Hi Hanif, could you please also upload your .dyn file so we could see how you are using the Excel document, as well as an image/sketch of your desired result? If you provide more information you will likely get more effective help more quickly :slight_smile:

twisted tower sounds like https://www.linkedin.com/pulse/just-another-tower-cesare-caoduro/ by @Cesare_Caoduro3 :stuck_out_tongue:

This is my dynamo file and some images of the result:

As you see this file has some problems. I think first it twisted the profile at base and then twisted the lofted profile again.
I need to get the results on the Mass page in Revit to be able to Selecting surface for Griding it & …
Thank you for your kindly answer.

Before I give an incorrect direction, is this around the result you are looking for?

I think it’s true, but I’m not sure if it’s possible to give the Dynamo file this model so that I can see the three-dimensional volume to be sure of it.

Thank you very much

I would send you the file, but it is part of your graduate thesis :see_no_evil: Does this look right?

Your graph was getting close, I think you just thought it was generating incorrectly because you had preview on for both Geometry.Translate and Geometry.Rotate

In either case, there are some unnecessary aspects of your graph - you don’t need to be creating as many ellipses as you were with Geometry.Translate, the lofting will still be smooth with less cross sections and will run more quickly.

Also the Excel file is not necessary for generating the ranges of your Z values for the distance input on Geometry.Translate, and the degrees for Geometry.Rotate. The link that @Thomas_Vogt shared brings you to this tutorial (PDF download): https://onedrive.live.com/?authkey=!ABAke5h1US5JMMk&cid=7EAF8D40A42D53C5&id=7EAF8D40A42D53C5!2763&parId=7EAF8D40A42D53C5!2104&o=OneUp

Since you are creating your ellipse with Ellipse.ByOriginRadii you can skip some of the first pages of that tutorial. The instructions for pages 18 and beyond will get you your results. Post back with progress (like I said, your Dynamo file was giving you close results so you’re nearly there) and I will be happy to give more specific advice !

Hi
Thanks so much.
My thesis is to get the exact angle of rotation of each profile, so I told my master he was agree that it’s okay if the algorithm is given to me by someone, but the algorithm should be able to read the rotation angle exactly from excel or we can put the entire Excel exactly in a list. And emphasizing that the rotation angle must be accurate.
Please help me again if its possible for you.
Thanks in advance for your cooperation

hi
Thanks so much.
I was able to model my geometry Turn it to the surface
But there is no choice in Mass in Revit for crate grid yet
please guide me

Please Help me to Export geometry Dynamo to Mass
hi
please Help me
I have been using Dynamo to generate massive geometry for our building.
I have a form in dynamo
but i need creative a Curtainwall system in to mass surface.
So I need to transfer the generated form to the mass unit completely to create the curtainwall system in Revit on its surface.
please guide me
