Hello! Hope someone can help me  The thing is... When I import a DWG file into a Family, and try to change in the Object Style the materials of the layers that I separated in AutoCAD, something happen and it all goes wrong. The chairs were supposed to be made of wood, and the table would be wood and glass. But like the picture I've attached the table is metal and wood, and the chairs too. I've attached also a window of the Object Style so you people could see that the settings are alright. This have happened to other Families too.

Well, I think I managed to solve this... I've exploded again the blocks in AutoCAD. First it was 8 blocks (table, glass and 6 chairs). Now there are hundreds of them (polygons).

This looks like it should be two or three families. A chair, a table and possibly (but I don't think it should be) a family that has a table and 6 chairs (I would rather see this as a group). Don't! explode your block in REVIT. Instead, seperate your blocks in AutoCAD into two files - chair & table. The blocks (chair & table) should be exploded but not the meshes. Make sure the individual elements ... leg, top, cushion ... whatever, are each on a layer which you can then assign a material to. IMPORTANT CONCEPT - Watch out for nested blocks. REVIT wants to assign materials based on the element's layer. What layer is a nested block on - its inserted layer or the layer the block was created on? REVIT doesn't seem to like this. Now you can insert the AutoCAD dwg into your family. (PURGE ALL UN-USED LAYERS FIRST and make sure you save with your current layer being one that you are using.) Keep working at it .... it gets easier.

I assumed here you are talking about importing 3D AutoCAD object into Revit. I noticed sometime, I download some components into project, when rendered they only showed up GRAY. You mean to say these are actually imported 3D AutoCAD object in the Family. So to assign material I need to explode it and then assign materials based on the element's layer. Kindly correct me or confirm this. Thanks.

Only 3d objects are capable of being rendered so that is what I'm talking about. You don't want to explode AutoCAD 3d objects in REVIT. What I was suggesting is that the objects be cleaned up in AutoCAD before importing into a revit family (or model). Any 3d meshes / planes that are in an autoCAD import can be rendered by assigning a material to their layer.

Yeah, the "exploding" part I was refering was in AutoCAD. In Revit, at least when I tried, to explode things they just disappear. Separating chairs from table is interesting, but I need the blocks together, so it's easier to move. Maybe blending families..........

I assume your term "blending" families means combining families .... Remember, I said you could have a third family that are the chairs and table together .... but I would prefer to define them together in the project as a group. You can place copies of the group where you want them and rotate independently - just as if they are a family. This is a much better solution.

If you nest the chair and table families into the third family that you suggest, you can create a parameter for different sizes of tables that show varying numbers of chairs arranged around them. This assumes the table isn't a particular table that doesn't just come in a single size. We have tables and chairs that we like and nest and load them so that on an instance basis we can select 4' round or 6' round or 8' round to see how they fit in the space...same thing with rectangular table just using four linear arrays instead of one circular array. Just a thought that won't apply in all cases, but may help in some.
