Wall: attach top/base, no API?

Anonymous — Mon, 30 Nov 2015 11:23:51 GMT

I searched around with no luck. So, to create a gable wall, the only way is to work out the profile and vertices?

Thanks in advance.

Dear Paper Plane,

Does this help?

http://thebuildingcoder.typepad.com/blog/2011/07/create-gable-wall.html

Please note that the sample external command CmdCreateGableWall discussed there is included in The Building Coder samples:

https://github.com/jeremytammik/the_building_coder_samples

It is therefore continously maintained and has been updated for more recent versions of Revit.

Cheers,

Jeremy

Thank you Jeremy.

I had thought there was a way like this:

First, ignore the detail of the wall profile, only create a rectangle wall;

Then, get IDs of the wall and a roof, attach these two using API.

Apparently it doesn't work this way.

Afaik, the top and bottom restriction of a wall can very well be specified by simply supplying an element id each.

However, afaik, these element ids must specify level elements, and these are resticted to being horizontal.

Ergo, no way to use these to specify a non-rectangular wall elevation profile.

Capisci?

Ciao,

Jeremy

Hi Jeremy,

The original poster and I are not trying to attach the wall to a level. We want to use the API to do what the UI allows which is attach the top and bottom of the wall to multiple elements such as a roof or floor. This can be seen in the UI in this video. http://autode.sk/1Q6e5oT

Because it seems like this is not possible with the API, could you please file a request with the development team?

Thank you
Harry

I want to be able to create curved gable walls by creating curved walls and attaching top to the upper roof.

Thank you

Any updates on this?

So far it doesnt seem to be included within the 2020 API as far as i can see.

Attach Wall top to an element (not level) as you can do in the revit UI

Thank you for your vote! Not much more we can do about it right now, I'm afraid. Vote, vote, vote. Good luck!

For now the only thing we can do is delete and recreate floors in my case.

Hope the development team reckons this issues soon.

That is easy. Take a look at the ADN Xtra labs sample to create a little house, Lab2_0_CreateLittleHouse:

https://github.com/jeremytammik/AdnRevitApiLabsXtra/blob/master/XtraCs/Labs2.cs#L42-L427

It creates four walls and attaches them to the bottom and top levels just as you request.

Impossible to say with zero information.

I would suggest working through the getting started material first of all to get a solid understanding of the basics of the Revit API and add-in architecture and then moving forward from there:
