Hi,

I Have a simple question.

What is the better way to use DWG files in revit.

A: One big DWG imported containing all layers and objects

B:The same file spilt up into multiple DWG and imported

/Best regards

Daniel Monsen

A big A-Cad file slows REVIT down it might be easyer to split em up and hide the parts you're not using at the time.

At least this is my experience

You can choose the options to link or insert the dwg.

You can also choose to have the dwg only show in the inserted view.

Then when you insert, you can select the dwg and choose hide in view when it slows you/Revit down.

My answer initially was don't use CAD files but in this case, you are talking about a site plan.  For the time being, site plans are better off in CAD but be careful with inserting CAD files because they will really cause you problems. 

 

To create a 3D site, you need to insert the CAD file but otherwise, all CAD files are better off linked rather than inserted.  If I still needed the site drawing after creating my 3D model, I would consider deleting the import and then linking it.  In this way, the DWG can be updated.

 

Finally, to improve performance, place your linked or inserted CAD files in a workset that can be un-loaded.  This is really important on very large projects.

Thanks guys, these insights are still valuable for me in managing DWGs in my project today!

 

Just to add to what WWHub said, 1 more reason to always link DWGs is because imported ones won't show in Manage Links! In a big model like mine with hundreds of views, it has become extremely tedious to purge any one imported DWG because I won't readily know which view or views it is in. Even if all copies of it have been found & removed, its symbol may still be there under VG > Imported Categories ...

 

So, be very disciplined about linking DWGs. I'm using DWG Explorer to clean models that didn't learn this lesson, but would rather prevent it from the source!
