Extract tesselated geometry from 2D component

[pmeigneux]

Hello,

I currently use the CustomExporter() function to extract tesselated geometry from the Revit Model.

I arrive to extract to obtain all 3D geometry from the 3D Revit component. 

But I didn't find a way to extract 2D geometry with this approach.

For example, I put a RVT file in attachment with some pipes components which are not extracted.

Thanks for your support,

Philippe

Dear Philippe,

Thank you for your query.

Yes, indeed, I am sorry to say that 2D geometry is not supported by the custom exporter.

I wish it were.

Best regards,

Jeremy

Hello Jeremy,

Thanks for your response.

Do you know if there is any workaround to obtain a tesselated component from 2D Geometry?

Dear Philippe,

Yes, sure.

Query the 2D element for its geometry in a view that provides what you need.

It will consist of curves, I presume.

Use Curve.Tessellate on them:

Hello @jeremytammik,

I take a look to your previous answer and I need to precise our question.

Indeed, it seems Structural and MEP components have a different behaviour from the architectural component. So we didn't find a way to use Curve.Tesselate on MEP elements.

Do you know a way to extract these following informations from Structural or MEP components with CustomExporter():

• extract tesselate geometry from Structural or MEP components, for example with (structural rebar or pipe see .rvt file in attachments)
• color of 2D components;
• transparency data on 2D component.

Thanks for your help,

Philippe

Hello @jeremytammik

I finally succeed to extract a tesselated geometry from 2D MEP component with CustomExporter().

However, I didn't find a way to extract the color and transparency associated on the Materials.

Do you know a way to obtain the Materials.node on the MEP.Curve function?

Regards,

Philippe
