Place point-based adaptive component on a model line

[RMohareb]

Hi @vancikv
first to host adaptvie family to line by using dynamo has a problem in API, yes you can do that maual but from API you can not for bug in revit API.

Create Adaptive Component Hosted on Line in Family Instance

See image and attached files. I am trying to write a Python Script that will place a 2 point adaptive at the 0 & 1 parameters of a line that is inside of a loaded Revit Family instance. [image] Here’s the issue - the code seems to work from the aspect of the Adaptive Component is placed in the project and the placement points know they are hosted to the family and to the appropriate parameter, but the Adaptive is Not placed in the correct position, nor does it move along with the host family…

secand: if you add adaptive point host by line you will face problem in the torsion angle (twist) and it is very difficult to solve and avoid this rotation.

for that i do not inset adaptive family host by line. I insert it in global and defiend it to be Z global and instant XY plan as @Draxl_Andreas wrote.

"BriMohareb_XXXX" Package for RevitXXXX Thread

This packedge use Dynamo Revit_2023 as plateform to integrating Revit_23, Civil3d_23 , Autocad, sofistik_2018, sofistik_2023 and Add extra geometry nodes to dynamo through API. It help bridge and tunnel engineers to create and Automate automate model and design. Also makes it possible to create complex bridge and tunnel elements by using Adaptive family [image]

Dynamo Adaptive Tunnel Family rotation and curves

take a look here, its a bit old, but the concept still applies

also you can use “BriMohareb_2023” to create the model and calculate the angle

Rotate Adaptive 3 Points Family arround X-Axis and Z-Axis

Thank you for your reply @RMohareb I have revit 2021, so I can’t open your files I placed another ref. point but still can’t rotate XZ Plane. [Tunnel_script] [tunnel_1]

also this family templet maybe help you
