What do you mean by the above statement? "Part by part"?  "Single surface"?

Hi @Anonymous!

If I understand your issue, you have a toposurface comprises by multiple parts and you want export to IFC these elements as a single part, correct?

Could you share some images of your toposurface for analysis, please?

[Anonymous]

Hi sir, thanks for your reply, yes you are correct sir, i will share the image now

Hi sir, thanks for your reply 

our issue is topo surface comprises by multiple parts and once we export to IFC these elements as a single part

[ari.monteiro]

Hi @Anonymous!

Configure the Export IFC Options like following image. Depending IFC version, this configuration will be different.

With this setting each part of toposurface will exported separately.

If you'll use the ifcSite class on Topography category, the Toposurface will be exported as single element, regardless you have modeled each part isolately.

Please, let me know if you got solve your issue, ok?

Best regards!

Hi @Anonymous!

To export the building pads to IFC, setting at "Site->Pads" category in "Export IFC options" the IFC class "IfcFooting" like the image below.

After, just export the IFC file using the same configurations that you presented in you first post.

Please, let me know if you got solve your issue, ok?

Hi @Anonymous!

I'm sharing at link below 3 files:
1. The project that I've used to study your issue
2. The ifc file for this project, exported as I suggested
3. The configuration IFC file that you can load in "Export IFC Options"

My test files

https://drive.google.com/file/d/17IaLlNTvNx4625rnktKDh7I5lmLDBTKw/view?usp=sharing 

Please, check these files. You'll be note that in my IFC the toposurfaces coming as a seperated elements and bulding pads is exported, too. The image bellow show how my IFC file is visualized into BIM Vision software:

Two important information: I'm using Revit 2019 update 2.2 and IFC 2019 (version 19.3.0) export extension.

Maybe, you should update you Revit and the IFC export extension. The last version of this extension can be downloaded by this link:

Sure sir, Thanks for your support 

i have one more doubt in the revit to ifc export, can we export an ifc along with architecture wall thickness? sir

kindly advise sir

[ari.monteiro · Accepted solution]

Hi, @Anonymous!

To export the wall thickness to IFC you should use the "IFC2x3 GSA Concept Design BIM 2010" setting.
