Is there a way to create a sloped buildingpad programmatically?

Anonymous — Tue, 20 Dec 2016 19:21:50 GMT

Hello everyone, I'm trying to create a sloped building pad but unfortunatelly I couldn't find a way to pass the line arrow like the we can do on floors. And I couldn't find a way to edit the pad so I could inject slope information as well. Is there a way to do that?

Thanks in advance,

Thiago Almeida.

Dear Thiago,

Happy New Year to you!

I cannot answer your question offhand, so I passed it on to the development team.

Cheers,

Jeremy

Dear Thiago,

I heard back from the development team. They say:

As the owner of Site, I don’t think we provide the API functions for sloped building pad yet, including creation and edit.

So, right now, I am not sure there is a way to do that…

Sorry for the bad news.

Cheers,

Jeremy

As there is no direct way to create a sloped buildingpad, you could go the indirect route by copying a buildingpad from an existing document.

The drawback is that you have to know the shape of the buildingpad in advance, as you cant change it using the API. (setBoundery will remove the slopearrow!)

workflow:

preparation:

create helperDocument manualy (containing 1 toposurface and 1 sloped buildingpad)

programming:

load helperDocument

find modellines of the boundery and the slope arrow using the delete and rollback trick. ( List<ElementId> _Ids = doc.Delete(buildingpad.Id) )

the slope arrow is the modelline with name "Slope Arrow".

reposition the modellines to new positions.

reposition the slope arrow to new position.

set slope arrow heights (BuiltInParameter.SLOPE_START_HEIGHT & BuiltInParameter.SLOPE_END_HEIGHT)

copy to Target document

ElementTransformUtils.CopyElements(helperDocument, new List( buildingpad.Id) , target, Transform.Identity, opt);

Hi Jeremy , happy new year to you
I thought I was missing a method or a Util class. It is unfortunate that we don't have it at all , but let's hope it gets implemented in the future.

Thanks for your efforts,
Cheers,
Thiago Almeida.

Hi FAIR59, Thank you for the hint, but unfortunately I am trying to create Building pad based on different scenarios and shape. I appreciate you help anyways.
