Create DWG blocks from Revit families

When exporting a 2D view to DWG format in Revit, the families are broken down into individual line segments in AutoCAD rather than exported as blocks. I’m already aware of the EDER-Tool plugin, which can enhance the export process, but I’m interested in exploring other methods such as Dynamo, Revit API, or an alternative plugin.

Any suggestions would be appreciated.

Hello @p_wehbi 

 

thank you for your question! 

I understand the challenge you’re facing when exporting 2D views from Revit to DWG format, where families are being broken down into individual line segments instead of being exported as blocks. 

While this is the German forum, I will do my best to assist you. When exporting from Revit, one approach you could explore is using the “Group by Family” option in the export settings. This can sometimes help maintain the family structure as blocks in DWG. Additionally, tools like Dynamo or custom scripts with the Revit API could be used to group the line segments into blocks during or after the export. Plugins such as the EDER-Tool, which you mentioned, or similar ones can also enhance this process, depending on your specific needs.If you have already tried these steps and are still encountering issues, let me know, and I will try to assist further. 

 

I hope this helps!

 

Best regards,

Sara

Hello @sara_elsayed15,

Thank you for your reply.
Unfortunately, I couldn’t locate the “Group by Family” option in the export settings. Could you please tell me where exactly to find it?
In the meantime, I’m exploring the possibility of exporting Revit views using the Revit API. I’ll be sure to leave a comment if I come across any difficulties.

first sorry for my english

 

but you have build the familiy wrong

if the family is build correct it will export as a block 

 

Revit familiy

 Autocad block

The problem is the 2D symbol of the installation plan

This must be a detail element of the family 

and build from model lines

then load in the main family

Then it will be exported as an autocad block

 

Example

 But Revit builds a seperate block for every instance 

so it is not possible toi count them cause they ghave diffrent block names

Hi @a_machek 

The disadvantage of this method is that the 2D representation of the symbolic lines is included in the 3D geometry.

As you know, electrical elements are typically represented in Revit with symbolic geometry that is much larger than their actual physical size. These symbols are purely representative and do not reflect the real dimensions of the elements. As a result, this approach may lead to numerous unreliable clashes that are technically incorrect.

One potential solution is to turn off this subcategory in the 3D view before exporting to IFC or Navisworks. However, keep in mind that Revit's internal clash detection tool will still register clashes if these symbolic lines intersect with other objects.

Yep correct 

We split all electrical elements to 2D and 3D an 3D Collision

So that we could correct export it to Navisworks for collision check

Bit i think the question was not the collison it was how to build the familiy so that it will exported as a block
