Automatic conversion of CAD Blocks into 3D Elements in Revit

Hi guys

I have a question. I’m trying to find a way to link or import CAD geometry into Revit and automatically create a 3D model based on that and specified families. I found that there are two ways:

  1. The first one is to export the geometry of CAD Blocks to Excel, Read the Excel file by dynamo, create points based on XYZ coordinates and place the families which does not work for me as shown below:

  2. I found in this forum that there is another way to do it without using Excel file.

Can anyone help me to do it? Thanks :slight_smile:

What does the error say? Are your inputs numbers?

Do you know how I can solve it? Thanks

You’ll have to convert the string back to a number. Search the library for a node that will do just that. Please show some effort and/or search the forum before asking questions.
