Create curved sections!

Anonymous — Fri, 26 Jul 2019 05:46:55 GMT

Hi,

i am working in very large projects where the whole building is radial, keep parallelism is imposible, but the worst is radial sections, we have 100-400m sections to produce.

Do anyone know if with the API is possible to create a new section tool?

thanks

alex

The API doesn't allow you to do anything you cant already do OOTB with Revit, so no.

However, in theory it would be possible by writing an algorithm which could generate the section (output as detail lines for example) by processing the geometry which hits your section line. This would however be quite a significant undertaking, and there would be limitations, such as restricting the process to only output the section cut, as projections would either need to be stretched or shrunk depending on which forward-direction your section cut is taking.

Dear Alex,

Nice to hear from you again after a long time.

I hope you are doing well down under.

Thank you for your query, and many thanks to Thomas for his helpful point.

If Revit does not support full-fledged curved sections OOTB, then you cannot create them programmatically either.

However, you could perfectly well create something quite similar yourself using the API.

The most difficult part to achieve might be full associativity.

However, it sounds to me as if you can save thousands of hours by creating them programmatically.

Also, you presumably have a pretty clear spec on what you need to see and what not in your curved sections.

Obviously you can draw a curve through the model, use that API to determine what is located vertically above it at what point, and represent that in a useful way.

So, I would say yes, you can probably programmatically achieve what you need, or at least the most important aspects of it.

I hope this helps.

Best regards,

Jeremy

Thanks Jeremy for your answer! Is an honour to have you in my network...

I hope we will meet again soon, let me know when you come down under.

I was aware that Revit API and Revit are quite at the same pace... Unfortunately. I was hopping more API could be released as we now can have new geometry since R19?

Cylindric projection should not be a problem for Revit and because there are circular grid should have the view tool adapted to that, I guess is a long term requirement.

For my problem today I need a solution, I have 2 choices, find someone to build the tool for us or teach our team coders to learn how to create that tool. It will not be simple as the project has a complex structure and MEP to LOD350!

I need something ASAP, can you recommend me the best strategy to achieve this?

Suggest a consultant/Autodesk dev/guidance to code?

Thanks so much for your help

You could always contact Autodesk Consulting Services:

Alternatively, maybe somebody here in this forum might be up for the job?

Good luck!

Cheers,

Jeremy

Hi Thomas,

Thanks so much for your offer! I am considering it.

I am internally discussing with the team if we have budget and/or resources to built a API tool, I believe we should after Jeremy's message with some hope... Once we are ready I will contact you to provide more details.

I will keep you updated.

Alex

@Anonymous Hi Alex, how did you solve it in the end? I use Sofistik Bridge Modeller for curved sections. They're not associative, but I doubt we'll get there anytime soon, so I've accepted that for the time being. What bothers me however is the need to define the section plane in terms of road alignment, which makes it unnecessarily hard to use in the context of buildings. So if someone can do better, I'd like to know.
