Applying materials to surfaces

[uagrad89]

If this has been answered previously, I apologize, but I didn't see it when I searched for it.

I was applying a material to some objects in AutoCAD 2009 this morning as an example for a class that I teach. I had a box and a surface that had been drawn on one side of the box. When I applied the materials to the objects, the box looked fine but the material on the surface did not appear correctly. In my case (and I have done this 4 times this morning with similar results), it appears that the side views are the ones that have the problems. I created surfaces from the top, bottom, front, back, and even left sides (initially) without any problem at all, but when I went in and changed the material the left and right sides are incorrect.

I also tried creating a box then exploding it to get the surfaces and applying material individually to each surface and got the same result.

Any help would be greatly appreciated.

Try to change facetres variable.

Thanks, but no, this has nothing to do with it, unfortunately. Even if I could get it to work on the right and left side, this would mess up the other 4 sides where it is applied correctly.

I'm using AutoCAD 2009, by the way. I didn't say this in my original email.

I drew a box and applied a material to it which applied correctly to all 6 sides. I then exploded the box to get surfaces and again, the material stayed applied correctly. After that, I removed the material from the top, front, and right of the object, then reapplied the material. The material went back on fine in the front and top views, but was messed up in the right view. The same thing happened in the left view.

The same thing happens when I try to apply a material to a planar surface created in either the right or left UCS.

The location of my UCS does not appear to have an effect. I have tried it in all 6 standard UCS views with the same results. I even went so far as to change my UCS before I created my material - granted, that shouldn't make a difference, but sometimes you just never know - and of course that did not work.

I've tried it multiple times on multiple machines, so it is not machine specific. I just wonder if anyone else has encountered the same thing.

Just in case anyone is curious...

The MATERIALMAP command fixes it. You can type this command then choose the "Planar surface" option and select the face that has the messed up material. I happened to be prowling around today in a book and found it.

I still don't understand why this happens only on the right and left faces. This seems like a glitch in AutoCAD that should be fixed at some point. It's odd that the material only goes away on those faces and not the others - at least, it hasn't yet.

Maybe everyone already knew and didn't want to tell me. :-)
