Can't delete object in imported dwg

[philvanderloo]

This is the first time I've tried exporting a revit file to a .dwg and then importing that into max. Everything seemed to be working well until I tried to delete objects. Nothing will delete.

Is there a way to make this happen?

Thanks

Only time I've ever had trouble deleting an object is when I use File link.

I'm not seeing a choice other than fbx. Don't recall ever having that problem with link Revit but had plenty of other probs. So I'm trying converting to .dwg and then link autocaf on import, (for lack of choice as far as I am seeing.)

You should be able to apply a poly-edit to the revit model, then go in and switch to element. Select the piece you want to delete and scroll down to Edit Geometry where you can hit the Detach button. Close out of the poly-edit modifier, find the piece you detached and delete it.

 

Hope that works for you.

You can't delete linked objects. If you need to delete them, you either need to delete them in the original DWG file or merge the link into your scene, then the objects full exist in your scene and you can do whatever you want to them.

 

As a general rule if you are linking files (Revit, DWG, whatever) you want to make sure you are happy with the scene in the original format. You don't want to have to do much cleaning once you are in Max as it becomes a ticking timebomb if you apply edit poly/mesh modifiers to everything. Because if you apply and edit mesh/poly and delete faces or objects, and you change the original geometry in the source file, that edit mesh/poly modifier will explode as you have now just change the vert order in which that modifier was relying on. So now, you have to find that object, delete the modifier, and re-do the modifier all over again. And you'll need to do this each time that object changes in the source file. So just make sure your source file is clean and you won't have to mess around with this stuff.

 

If you want 100% control over your objects, don't leave the link live. Merge it into your scene. I would do the link initially as you get better options (especially in terms of FBX files) but then immediately merge (aka bind) that link into your scene.

I always get that evil piece of geometry every now and then that wont die. Born of File linking and surviving the merge. Some how coming back for vengeance for me trying to delete it out of existence.

Go back in to autocad and strip out what you don't want there and do a wblock on the area you want.

I'm curious, why are you taking your revit into Autocad and then into 3ds Max? Why not just link directly from revit into 3ds Max and set the model to separate by material???

It would be much easier to import your revit file straight into max. If you have done it though 'manage links' on the second tab press bind and you should be able to delete objects which were imported.

The main reason behind exporting a Revit file to DWG is that curved surfaces in the DWG export are 100,000 times better than FBX. You actually get a curved surface that you would expect if you had modeled it directly in Max, not some jumbled grotesque mess of verts.

 

Though usually you only want to export the curved surfaces as a DWG and leave the others to either an FBX file or linked directly to Revit.
