Tunnel interpolation

[derek_marechal]

HI , I`m beginner with corridor fonction, i need to modelize an tunnel, i did my assembly and , put it on my alignement , but i have an conicale transition par between 2  assembly , and i try to figure how to interpolate between those two profile .. sorry my writting in english is bad , here an photo of my profile/assembly that i need to connect

Hi @derek_marechal, do you have a parameter to define the width and height of the tunnel? If so, and you are using C3D 2023, then I think you can take advantage of the corridor transitions tool to achieve that.

I hope this helps. Best regards!

Where i set the witdh and height of teh tunnel, im very beginer with those tools, im more building guy, its my first corridor- tunnel modeling

Is it possible for you to upload the file and the subassembly to see if there is any chance to create the transition using the tool I mentioned?

here`s the dwg

Hi @derek_marechal, I checked your DWG file, and I realized you are creating the tunnel with what seems to be a subassembly from Polyline. Therefore, we cannot use the transitions tool from C3D since we should have parameters to do so.

It would be best to create a custom subassembly that handles at least width and height. Then you'll be able to use transitions. Furthermore, you can directly program the transition between regions within the custom subassembly.

Best regards!

OH thanks , if i do the subassembly with subassembly composer hit would be ok? because i had subassembly i did with subassembly composer for pratice but it was easier et faster with polyline !

Yes, it will work if you have set the parameters. However, it depends a lot on how you computed the rest of the geometry of the tunnel. If other variables are not dependent on these two variables (Width and Height), you should look for the appropriate parameter to edit to achieve the result you expect.
