Placing materials

I am working on a 3d solids model and would like to attach materials. I am using ADT2010. I can see all of my materials but when I drop them in I get an error message stating that some of the features are not supported by autocad and the materials was not attached. I'm lost. Any help would be greatly appreciated.

Thanks

Do you have any materials in the material editor at all? If so, try selecting the object and assigning it a material through the properties palette. You could also try creating your own materials rather than dropping the preset ones.

The approach is different between regular solids, and AEC objects, which are you using?

If you're using your TP for AEC objects it won't work. Use the material browser under the render ribbon. The materials found ther can be used for solids and meshes NOT AEC objects.

You can use any material for any object. All you have to do is right click on the material in the browser, select "copy to active tool palette", then find it on the tool palette, right click and select "convert to AEC material".

thanks for the help, it seems that 2010 did not load the library. My laptop is running ADT3.3 and it loads when you intall the program. I still can find the library on the DVD. I am loading 2011this weekend so I am hoping to find it then. Thanks for your replies. I was able to manual add custom materials now I just need to find where the stock is hiding.

Post 2007 ADT works in a slightly different way, keeping all materials within each drawing. You can set up a material library type tool pallette in the way that Red333 mentioned above. I'm not sure, but this may then link back to the drawing from which it was created, so you could have a reference file of materials and tool pallette links to them all. Check this out though, I've not had the chance to set this kind of a system up yet as i'm condatantly tweaking my materials. Unfortunately I don't think there is a direct wasy to covert the old style libraries, just a matter of recreating your materials from scratch. It's worth it though as post 2007 also bought in the mental ray renderer which gives really good results over the older versions.
