Hi, any solution will likely require a bit of coding in a scripting component.
I think this is a tricky one to solve without any meta-data about the corners. Somehow you’d need to reverse-engineer the contour to get the radii and corner-point handles, then insert plates in Tekla and modify the chamfers according to that data.
Since you can’t edit the plate chamfers using the Plate component you’d need a scripting component to modify them afterwards, there are some ideas and examples in this thread:
Another option might be to interpolate the polyline to get smooth corners, and then use this script to convert that curve into arcs and lines which are translated to arc-point chamfers in Tekla:
To be fair, GH is programming and you’re in a programmer mindset even if you don’t realize it, C# is just a different syntax… so if you’re determined, ChatGPT can do wonders nowadays with suggesting code snippets for GH scripting components. Unironically You could e.g. feed existing code from the examples in the thread into it and ask for corrections or improvements to match what you’re after.
The reverse-engineering of corner radiuses and handles will be the challenge regardless of whether you’re trying to solve it directly in GH or by using some other coding. If you can get hold of that info some other way from the exported data you have a much better starting position.
