Best Way to Model An Existing Building?

Hello there,

I'm totally new to this Revit modelling so please bear with me.

I have to model an existing building to include some refurbishment elements and an extension.

I can model the extention easily but am struggling with the refurbishment part. At the moment I have attached the 2D cad survey (no point cloud survey I'm afraid) and added my refurbishment elements in Revit so they are 3D. Is this good practice? There is no time available to model the building in 3D from the existing 2D Cad data.

Any ideas guys? I probably spend 50% of my time working on existing buildings with often 2D surveys so I would appreciate any thoughts or comments if I've taken a wrong turn somewhere.

Cheers

Andy

Off hand - I think you are working just fine.

If you don't have time to redo the entire existing building in 3D - stick with doing the referb portion in revit and using the 2d cad imported in.

 

If they want all of the building in 3d - then you can add that to the timeline and cost.

I agree with Lisa on how you are handling it now.

 

We do the same thing here.  Link or Import CAD files into Revit and only draw 3D items close to the addition or remod area.

 

I also have placed room separation lines over the cad file so I can get room tags in Revit to look the same.

Hi LD,

Thanks for this! It's good to know I'm going in the right direction.

Hi,

 

I understand you import the 2d Cad plans into Revit and then model the new, however when it comes to sections that show both new and existing how would you go about this?

 

Thanks

If you have 2D cad sections & elevs, import these into your appropriate section or elevations view with the CURRENT VIEW only option toggled at the select import file dialog. Once the file is visible in the view, move it to correct location. Simple.

 

Otherwise you will have to model the existing building if the info isn't available. Why not just use a simple mass model to replicate it.

Thanks for the response. I guess using a simple mass model is an easy solution!

If you can get away with modelling it in very basic form too right. Takes seconds.

I was also wondering the best way to go about adding detail elements such as wall plates and joist hangers to my sections? Sorry I am very new to Revit!

nothing to be sorry about, we all had to start somewhere. We are here to help!

 

There are detail components prebuilt that you can use in the library. They are 2d elements that can be placed in a section or elevation.
