Help on putting a design on my walls.

[Agentoo]

I cant put any texture on my walls when in 3d mode.

click your F1 key and type in materials under the index tab. Scroll down and select applying under the material map heading.

Attaching a MATERIAL with RMAT (or as CADKID explained) will provide a texture when RENDERing.

If you want something that plots with the drawing you'll need to use HATCH or BHATCH. Prior to hatching, roll your UCS to match the wall you're going to hatch, making sure the origin is on the wall.
